Article 4 of 5 — Pulp and Paper Industry

How Khash Would Implement ICML 55 Lubrication Management in a Pulp and Paper Mill Through Noria-Style Consulting and Service Programs

I will continue using Khash as the lubrication-management implementation lead or consultancy program owner. This article is written for a complete pulp and paper operation, including wood yard, pulping, stock preparation, chemical recovery, paper machine, tissue machine, corrugating, converting, utilities, and wastewater systems.

1. Strategic intent: why pulp and paper requires a formal lubrication-management system

A pulp and paper mill is one of the most demanding lubrication environments because it combines water, steam, heat, high-speed rolls, heavy nip loads, chemical exposure, fiber contamination, paper dust, hydraulic precision, long circulating-oil systems, high lubricant volumes, wet-end moisture, dry-end heat, and continuous production pressure.

A paper machine may contain hundreds or thousands of lubrication points, including bearings, gears, couplings, journals, cylinders, and valves. Many of these points are lubricated through large circulating-oil systems rather than isolated manual lubrication points, which means one lubricant system may simultaneously affect dozens or hundreds of bearings and gears. (machinerylubricationindia.com)

For Khash, the lubrication challenge is not only selecting the correct paper machine oil or grease. The real task is to create a governed lubrication-management system that controls:

lubricant selection
lubricant cleanliness
water removal
fiber and paper-dust exclusion
circulating-oil flow
filtration
reservoir health
hydraulic cleanliness
grease delivery
automatic lubrication system integrity
oil analysis
condition-based oil changes
leakage and top-up discipline
lubricant storage and handling
operator inspection
RCA and continuous improvement

ICML 55 is the appropriate framework because it is a lubrication-specific asset-management standard. ICML describes ICML 55 as a group of standards aligned with ISO 55000 and intended to support effective, audit-ready management of lubricated mechanical assets. ICML 55.1 defines requirements, while ICML 55.2 provides implementation guidance that organizations can customize to their needs. (Lubrication Council)

Khash’s pulp and paper objective should therefore be:

To implement an ICML 55-aligned lubrication-management system that improves machine availability, protects paper machine circulating-oil systems, controls water and particle contamination, extends lubricant and component life, reduces lubrication-related downtime, improves product-quality stability, reduces lubricant waste, and integrates lubrication into reliability engineering, maintenance planning, operations, procurement, EHS, and management review.

2. Pulp and paper lubrication philosophy under ICML 55

A pulp and paper lubrication program must be managed as a closed-loop technical system, not a collection of PMs. Khash should define the lubrication lifecycle as:

Lubricant specification
Approved product selection
Supplier and procurement control
Lubricant receiving inspection
Storage and handling
Filtered transfer
Machine application
Circulating-oil monitoring
Flow verification
Oil sampling
Oil analysis
Grease inspection
Filtration and dehydration
Corrective work order
RCA
Waste handling
Audit
Management review
Continuous improvement

This is especially important in pulp and paper because paper machines often use large circulating systems. These systems pump oil from a central reservoir through supply lines to many lubrication points, then return the oil to the reservoir. Circulating oil provides cooling, lubrication, contaminant transport, and centralized filtration opportunities. (machinerylubricationindia.com)

3. ICML 55 framework translated into pulp and paper requirements

ICML 55 management area	Pulp and paper implementation focus
Lubrication objectives	Reduce dryer bearing failures, press-section hydraulic failures, roll bearing distress, gearbox failures, vacuum pump failures, oil contamination, unscheduled shutdowns, and lubricant waste.

Management review	Review KPIs, critical risks, RCA actions, training progress, oil-analysis exceptions, hardware progress, and business value.

4. Noria-style consulting and service delivery model

Khash should implement the pulp and paper program through a Noria-style Lubrication Program Development model: Ascend Assessment, Engineering Design, and Program Implementation. Noria describes Lubrication Program Development as a three-phase process with typical average durations of approximately one week for Ascend Assessment, six to eight weeks for Engineering Design, and one to two years for Implementation. (Noria Corporation)

Noria’s Engineering Design phase is particularly relevant to paper mills because it surveys lubricated assets onsite, builds dynamic lubrication procedures from machine operating conditions and OEM requirements, and provides lubricant, hardware, procedure, data, implementation, and metrics deliverables through LubePM. (Noria Corporation)

5. Phase 1 — ICML 55 / Ascend baseline assessment for a pulp and paper mill

Khash should begin with a full-site lubrication assessment. In pulp and paper, a lube-room audit alone is not sufficient. The assessment must include the paper machine’s wet end, press section, dryer section, calender, reel, winder, stock preparation, pulp mill, recovery area, utilities, wastewater treatment, and all storage/handling interfaces.

5.1 Assessment scope

5.2 Assessment questions

Khash should ask:

Does every critical lubricant system have a defined owner?
Are paper machine oil systems treated as critical assets or simply as reservoirs?
Are oil samples drawn from representative live-zone sample points?
Are there separate sample points before and after filtration?
Are paper machine bearing oil flows verified daily?
Are flow meters calibrated and readable?
Are low-flow alarms functional?
Are filters sized for viscosity, temperature, dirt load, and required cleanliness?
Is water removed continuously or only after alarms?
Are vacuum dehydration, coalescing, centrifuging, or offline filtration used where justified?
Are oil changes condition-based or calendar-based?
Are lubricant leaks tolerated as “normal paper machine behavior”?
Are captured leaks ever reintroduced to the system without adequate filtration and testing?
Are hydraulic fluids in press, calender, and coating areas controlled to servo/proportional valve cleanliness requirements?
Are wet-end bearings protected from water and fiber ingress?
Are dry-end bearings protected from heat, oxidation, and varnish?
Are grease systems inspected to confirm actual grease delivery?
Are food-grade or H1 lubricants required in packaging, tissue, hygiene, or food-contact-adjacent applications?
Are all lubricant substitutions reviewed technically before use?
Are oil-analysis red alarms converted into work orders?
Are lubrication failures coded in the CMMS?
Are operators trained to recognize lubrication abnormalities?

11. Lubricant selection and consolidation strategy

Pulp and paper mills often accumulate too many lubricant SKUs because of mixed OEM recommendations, legacy products, mill expansions, specialty applications, and emergency substitutions. Khash should consolidate only after an engineering review.

11.1 Lubricant families in a pulp and paper mill

Lubricant family	Typical applications
Paper machine circulating oils	Wet end, press, dryer section, bearings, gears, shared circulation systems
Hydraulic oils	Press section, calender, coater, winder, roll loading, hydraulic actuators
EP gear oils	Gearboxes, reducers, wood yard drives, stock-prep drives, conveyors
Synthetic gear oils	High-temperature, high-load, or energy-critical gearboxes
Turbine oils	Steam turbines, generator auxiliaries, large rotating equipment
Compressor oils	Plant air, instrument air, process air systems
Vacuum pump oils	Liquid ring or dry vacuum systems where oil is used
High-temperature greases	Dryer area, Yankee area, corrugators, recovery area bearings
Water-resistant greases	Wet end, stock prep, washers, pulp mill equipment
Electric motor greases	Motors for fans, pumps, drives, conveyors
Food-grade/H1 lubricants	Packaging, hygiene, tissue, converting, corrugating where required
Chain oils	Corrugators, conveyors, dryer-area chains, converting lines
Open-gear/specialty lubricants	Specialty large gears, racks, or slow-speed exposed systems where present
Wire-rope lubricants	Cranes, hoists, roll handling equipment
Assembly and anti-seize compounds	Maintenance, threaded fasteners, high-temperature assemblies

11.2 Paper machine oil selection parameters

Paper machine oil selection is critical because the oil may serve bearings, gears, and sometimes hydraulic functions within the same machine architecture. Khash should specify:

ISO viscosity grade
viscosity at operating temperature
viscosity index
demulsibility
oxidation stability
rust and corrosion inhibition
antiwear performance
EP performance where gear loads require it
filterability
additive retention through filtration
foam tendency
air release
water separability
thermal stability
compatibility with seals and paints
compatibility with existing oil
cleanliness target
water target
oil-analysis alarm limits
food-grade requirement, if applicable
OEM approval
approved alternate

Paper machine oils are formulated for water contamination, loads, oxidation resistance, rust inhibition, antiwear protection, and sometimes detergent performance. Viscosity and demulsibility are especially important because the oil must be pumpable while maintaining film strength and separating water effectively. (machinerylubricationindia.com)

11.3 Grease selection parameters

For grease-lubricated paper mill applications, Khash should specify:

NLGI grade
base-oil viscosity
thickener type
water resistance
corrosion resistance
oxidation stability
mechanical stability
dropping point
high-temperature capability
pumpability through centralized systems
low-temperature pumpability where applicable
compatibility with existing grease
bearing speed factor
load capacity
color or staining risk
H1/food-grade status where required
purge behavior
relubrication interval
calculated relubrication volume

Paper machine greases may require high base-oil viscosity, water resistance, and color control where grease could contact the paper product. (machinerylubricationindia.com)

11.4 Consolidation rules

Khash should not consolidate:

paper machine circulating oil into generic hydraulic oil without OEM and additive review
press-section hydraulic oil into paper machine oil without valve-cleanliness and compatibility review
high-temperature dryer or corrugator grease into general multipurpose grease
wet-end water-resistant grease into dry-end high-temperature grease without design review
food-grade applications into non-food-grade products
electric motor grease into heavy EP or moly grease
vacuum pump oil into compressor oil unless OEM-approved
turbine oil into paper machine oil without oxidation, foam, demulsibility, and additive review
detergent paper machine oils into non-detergent systems without flushing and compatibility review

The output should be an Approved Lubricant List containing product code, application class, viscosity or NLGI grade, OEM approvals, food-grade status, storage code, transfer-container code, approved alternate, and management-of-change restrictions.

12. Contamination-control strategy

In pulp and paper, contamination control must address water, steam condensate, paper fiber, paper dust, sawdust, process chemicals, coating pigments, starch, black liquor, white liquor, caustic, acids, corrosion products, and wear debris.

Oil analysis providers emphasize that pulp and paper production combines heavy loads, high speeds, dirty and wet conditions, and contamination from water, dirt, sawdust, and metal particles that can interfere with the very thin oil film separating moving parts. (spectrosci.com)

12.1 Water contamination

Water is the dominant contaminant in paper mills. It enters through:

wet-end roll seals
steam joint leakage
condensate leaks
washdown
humidity
cooling-water leaks
reservoir breathers
open hatches
poor drum storage
maintenance work
hydraulic cylinder rod ingress
vacuum pump carryover

Khash should implement:

demulsible paper machine oils
reservoir residence-time review
sloped reservoir bottoms
low-point drains
BS&W bowls
desiccant breathers
water sensors
Karl Fischer water testing
crackle screening for field checks
vacuum dehydration
centrifugation
coalescing filtration
steam-leak RCA
cooler leak testing
wet-end seal upgrades
shutdown preservation controls

12.2 Particle contamination

Particle sources include:

paper fiber
filler particles
coating pigment
sawdust
paper dust
airborne debris
corrosion particles
maintenance dirt
filter bypass
seal wear
gear and bearing wear debris

Khash should implement:

full-flow filtration
return-line filtration
offline kidney-loop filtration
proper beta-rated filters
filter differential-pressure monitoring
sealed reservoirs
sealed top-up systems
filtered transfer carts
dedicated clean sampling equipment
maintenance contamination-control procedures
flush criteria after major maintenance
patch microscopy for abnormal particle sources

Paper machine circulating systems benefit from multiple filtration points: supply filters, return filters, and offline filters. (machinerylubricationindia.com)

12.3 Chemical contamination

Chemical contamination may come from:

black liquor
white liquor
caustic
acids
bleaching chemicals
peroxide
starch
sizing chemicals
coating chemicals
biocides
cleaning chemicals

Khash should control chemical contamination through:

seal upgrades
lubricant compatibility review
frequent visual inspections
water and acid-number trend review
corrosion metal tracking
root cause investigation of sudden viscosity, TAN, or FTIR changes
operator abnormality reporting
chemical-area lubricant selection review

13. Cleanliness, water, and oil health targets

Targets must be finalized using OEM requirements, system design, baseline capability, component sensitivity, and criticality. Khash can use the following starting targets during Engineering Design.

Asset class	Suggested starting cleanliness target

Corrugator high-temperature bearings	Managed by grease condition, temperature, relubrication accuracy, and contamination control

Water targets should be stricter for paper machine oil, hydraulic systems, turbine oils, and high-speed bearing systems than for low-criticality gearboxes. The important point is not only the absolute ppm number; Khash must manage rate of water increase, water-removal effectiveness, and recurrence.

14. Machine lubrication readiness

Khash should treat poor machine readiness as a design weakness. A technician cannot perform precision lubrication on a system that lacks sample ports, safe access, flow indication, drains, breathers, and filtration connections.

14.1 Paper machine circulating-oil readiness

Required hardware:

live-zone sample ports
reservoir sample port
pre-filter sample port
post-filter sample port
return-header sample port
flow meters at critical bearing supply lines
low-flow alarms
pressure gauges
temperature sensors
filter differential-pressure indicators
desiccant breathers
sealed reservoir hatches
bottom drains
water drain valves
BS&W bowls
offline filtration connections
dehydration connections
sight glasses
columnar level gauges
magnetic plugs or magnetic separators
reservoir inspection hatches
spill containment
clearly marked oil fill points
QR-coded inspection points

14.2 Hydraulic system readiness

Required hardware:

pressure-line sample ports
return-line sample ports
reservoir sample ports
high-efficiency breathers
offline filtration loops
filter differential-pressure indicators
online particle counters for critical systems
moisture sensors where water risk is high
clean quick-connect fill points
sealable reservoir covers
temperature and pressure monitoring
drain valves
hose-change cleanliness procedures

14.3 Grease system readiness

Required hardware:

tagged grease points
fitting caps
remote grease manifolds where access is unsafe
relief fittings
purge paths
centralized grease pump alarms
injector confirmation
blocked-line detection
pressure gauges
line protection
calibrated grease guns
color-coded grease tools
single-point lubricators where justified
route labels or QR codes

Automatic greasing systems in paper machines dispense grease from a central reservoir through injectors, but each line and injector must be inspected to confirm proper operation. (machinerylubricationindia.com)

15. Oil analysis, grease analysis, and condition monitoring

Oil analysis is central in pulp and paper because large oil volumes, high asset criticality, contamination exposure, and continuous production make condition-based decisions more valuable than fixed-interval changes. Spectro Scientific describes oil analysis as an important maintenance practice for pulp and paper companies because pumps, gears, bearings, compressors, engines, hydraulic systems, and other oil-wetted machinery are critical to avoiding unexpected failures and unscheduled downtime. (spectrosci.com)

15.1 Oil-analysis test slate by asset class

Asset class	Routine tests	Exception / advanced tests
Paper machine circulating oil	viscosity, acid number, water by Karl Fischer, ISO particle count, elemental analysis, FTIR oxidation, additive trend, PQ/ferrous debris	demulsibility, foam, air release, MPC varnish potential, RULER, membrane patch, analytical ferrography
Dryer section oil	viscosity, acid number, oxidation, water, particle count, elemental metals, PQ, additive trend	varnish potential, RULER, air release, foam, demulsibility
Press/calender hydraulics	particle count, water, viscosity, acid number, FTIR, elemental analysis, additive trend	patch microscopy, varnish potential, servo-valve deposit analysis
Gearboxes	viscosity, water, particle count, acid number, oxidation, elemental metals, PQ/ferrous debris	analytical ferrography, magnetic plug debris analysis, foam, demulsibility
Turbine oils	viscosity, acid number, water, particle count, oxidation, RPVOT where applicable	RULER, MPC varnish potential, foam, air release
Compressors	viscosity, acid number, oxidation/nitration, water, particle count, elemental wear metals	varnish/deposit testing, RULER, compressor deposit analysis
Vacuum pumps	viscosity, water, oxidation, acid number, particle count, wear metals	contamination identification, FTIR for process contamination
Greases	consistency, oil separation, FTIR oxidation, water, wear metals, contamination, microscopy	worked penetration, dropping point, thickener analysis, ferrography

Paper machine oil changes are often condition-based because of the large volumes involved, and typical oil-analysis variables include particle count, water, viscosity, additives, and wear metals, with periodic tests such as varnish potential, foam tendency, and demulsibility. (machinerylubricationindia.com)

15.2 Sampling frequency

Criticality	Example assets	Frequency
A-class	main paper machine circulating oil, dryer oil, press hydraulics, Yankee bearing oil, turbine oils	monthly, biweekly during instability, online sensors where justified
B-class	refiners, major gearboxes, vacuum pumps, compressors, major fans	monthly to quarterly
C-class	small reducers, minor pumps, noncritical auxiliary systems	semiannual, annual, or exception-based
Post-maintenance	flushed systems, rebuilt gearboxes, reservoir cleaning, oil changeouts	baseline sample after startup and follow-up sample after early operation
Abnormal condition	water ingress, low flow, foam, high temperature, filter bypass, hydraulic instability	immediate sample and corrective action

15.3 Oil-analysis workflow

Khash should enforce:

Correct sampling point
Correct sample method
Sample under stable operating condition
Flush sample port before capture
Record hours, lubricant age, top-up volume, filter change, and abnormal observations
Apply correct test slate
Compare to absolute, rate-of-change, and statistical alarms
Review by trained analyst
Convert alarm into work order
Close corrective action
Verify with follow-up sample
Update RCA and KPI records

16. Filtration, dehydration, and flushing strategy

16.1 Filtration architecture

Khash should design filtration according to system risk:

System	Recommended filtration architecture
Paper machine circulating oil	supply filtration, return filtration, offline kidney-loop filtration, filter differential-pressure monitoring
Dryer section	full-flow filtration, offline filtration, water removal, varnish monitoring where required
Press/calender hydraulics	pressure-line filtration, return filtration, offline filtration, online particle count for critical systems
Gearboxes	offline filtration for large or critical units, portable filter-cart connections for others
Turbine oils	high-efficiency filtration, water removal, varnish monitoring where applicable
Vacuum pumps	contamination-specific filtration and water management
Bulk oil storage	dedicated filtration loop, desiccant breather, sample tap, bottom drain
Top-up	filtered transfer through sealed quick-connects

16.2 Dehydration strategy

Water-removal methods should be matched to the oil and contamination mode:

reservoir settling
low-point draining
coalescing filtration
centrifugation
vacuum dehydration
headspace dehumidification
desiccant breathers
controlled reservoir ventilation
cooler leak repair
wet-end seal improvement
steam leak correction

16.3 Flushing strategy

Ecol’s pulp and paper service description emphasizes that flushing oil systems requires an additional filtration unit with capacity and flow rate beyond the system’s own pump and filters, with turbulent flow helping remove contaminants from dead zones. (Ecol)

Khash should specify flushing after:

new machine commissioning
major reservoir repair
pipework modification
bearing failure
gearbox failure
severe water contamination
varnish/deposit event
lubricant incompatibility event
unapproved oil addition
catastrophic filter failure
major maintenance outage

A flushing plan should include:

target cleanliness
target water level
target oil temperature
flushing oil selection
turbulent flow requirement
filter beta ratio
dead-leg flushing method
sample points
filter change criteria
final verification samples
acceptance certificate
restart oil-analysis baseline

17. Precision lubrication task engineering

Khash should eliminate vague PMs and convert them into auditable lubrication procedures.

17.1 Bad PM language to eliminate

“Check oil.”
“Grease bearings.”
“Lubricate paper machine.”
“Top up reservoir as needed.”
“Inspect lube system.”
“Change oil annually.”
“Use standard grease.”
“Check filters.”

21. Storage and handling design

21.1 Main lube room

The main lube room should include:

enclosed, clean, dry space
humidity control where practical
bunded storage
sealed bulk tanks
desiccant breathers on tanks
dedicated filtration loops
dedicated dispensing lines
bottom drains
sample taps
clear lubricant identification
color-coded and shape-coded transfer hardware
food-grade lubricant segregation
grease storage cabinets

filter-cart storage
sample bottle storage
quarantine area for nonconforming lubricant
FIFO and shelf-life control
SDS access
spill kits
used-oil segregation

audit checklist

21.2 Satellite lube cabinets

Because pulp and paper mills are large, Khash should install controlled satellite cabinets near:

wood yard
pulp mill
recovery area
paper machine wet end
paper machine dry end
tissue/converting
corrugator
utilities
wastewater treatment

Each satellite cabinet should contain only approved lubricants for that area, protected from water, paper dust, fiber, and chemical contamination.

21.3 Lubricant receiving inspection

Every delivery should be checked for:

product name
product code
batch number
certificate of analysis where required
container condition
seal integrity
water contamination evidence
correct labeling
approved product list match
shelf-life status
food-grade/H1 status where required
storage assignment

No lubricant should be issued to the plant until it is confirmed against the approved product list.

22. CMMS, LubePM, and route governance

Khash should use the CMMS/EAM for work control and a lubrication-management platform for lubrication detail. Noria’s Engineering Design process identifies LubePM as a central delivery platform for procedures, asset data, recommendations, implementation management, approvals, and metrics. (Noria Corporation)

22.1 Lubrication master data

Each lubrication point should have:

site
department
machine section
asset ID
component ID
lubrication point ID

quantity
frequency
method
cleanliness target
water target
sample point
oil-analysis slate
route assignment
access requirement
safety requirement
inspection criteria
abnormality code
corrective action trigger
photo or diagram
responsible role

22.2 Route design principles

Routes should be separated by:

clean oil sampling versus dirty greasing
wet-end route versus dry-end route
running inspections versus shutdown tasks
hydraulic sampling versus mechanical lubrication
food-grade zone versus non-food-grade zone
high-temperature route versus general route
operator inspection versus lube-technician route
condition-monitoring route versus lubrication application route

Khash should avoid allowing technicians to perform precision hydraulic sampling immediately after dirty greasing routes unless strict contamination controls are used.

22.3 CMMS integration

The CMMS should manage:

lubrication PMs
oil sampling work orders
filter changes
breather replacements
water removal tasks
dehydration tasks
flow-meter inspection tasks
low-flow alarm corrective actions
oil-analysis alarms
leak repair backlog
grease system inspections
reservoir cleaning
flushing tasks
RCA actions
shutdown lubrication work
lube-room audits
training assignments

23. Training and competency program

Khash should implement role-based training.

25. Environmental, waste, and product-quality controls

Pulp and paper mills have strong environmental and product-quality drivers. Khash should connect lubrication management to both.

25.1 Environmental controls

Track lubricant consumption by machine and area.
Track used-oil volume.
Segregate used oils by type.
Avoid mixing paper machine oil, hydraulic oil, gear oil, and contaminated process fluids.
Use filtration and dehydration before disposal decisions.

Maintain spill kits at lube rooms and satellite cabinets.
Track leaks and repair backlog.
Reduce overgreasing.
Prevent grease purge from entering drains.
Control oil handling during shutdowns.
Document waste-oil disposal.

25.2 Product-quality controls

Lubrication can affect product quality through:

oil leaks onto paper
grease drip onto tissue or board
wrong lubricant in food-packaging zone
excessive lubricant near converting lines

30. Pulp and paper industry conclusion

For pulp and paper, Khash should implement ICML 55 as a circulating-oil, water-control, hydraulic-cleanliness, and machine-readiness program. The program will not succeed if it focuses only on selecting better oil. The highest-value improvements come from disciplined control of oil flow, filtration, water removal, live-zone sampling, condition-based oil changes, low-flow alarm response, hydraulic cleanliness, wet-end sealing, dryer-section oxidation control, centralized grease system verification, food-grade lubricant governance, and RCA.

The highest-priority assets for early implementation are:

paper machine circulating-oil systems, dryer section bearings, wet-end roll bearings, press and calender hydraulic systems, Yankee dryer bearings, corrugator high-temperature bearings, refiners, vacuum pumps, recovery boiler auxiliaries, lime kiln drives, critical gearboxes, compressors, turbines, fans, and finished-product converting lines.
