Biodegradable lubricants

Agenda: • Types of lubricants • Advantages and disadvantages • How to apply and maintain • US environmental protection agency • Best practice • Case study in the Netherlands • CJC oil conditioning systems

Types of bio-lubes

Natural, synthetics and blends such as:

• PAO (Polyalfaolefins) low temp properties

• Di-esters good anti-oxidation characteristics

• PAG (Polyalkyleneglycols) fire resistant

Note: Bio based property at least 51% of the lubricants is made of natural biomaterials.

Advantages and disadvantages: Good lubricating qualities polar nature Good solvents keep dirt and debris in suspension High natural viscosity and viscosity index Higher flash point then mineral oils Biodegradable and less toxic o Shrink rubber seals o Poor solubility with additives o Emulsifies with water high saturation level o Low oxidative stability o Higher pour point

C.C.JENSEN Benelux B.V., IP, Biodegradable lubricants, October 2013

How to apply and maintain: Consider the lube system design characteristics such as

operating temperature, pressures and flow rates.

Flush the system when switch from mineral to bio-lube, incomplete conversion leads to severe foaming, plugged filters, higher wear on components, increased operating temperature.

Correct sealing and hose materials.

Cross contaminations with other fluids during assembly, check whether the fluids are compatible.

Oil conditioning unit to maintain the required cleanliness to ensures the quality of the lubricants

US Environmental Protection Agency From 19 December 2013 ships sailing into US waters to use EAL (Environmental Acceptable Lubricants) in all oil-to-sea interfaces unless technically infeasible.

Most relevant components are:

o Stern tubes

o Rudder bearings

o Controllable Pitch Propellers

o Thrusters

o Fin stabilizer

Best practice: • Tank design and seals

• Oil type selection

• Configuration of shut-off valves, pressure relief and non return valves to minimize cavitation and shearing.

• Tank breathers (silica gel)

• Regular oil samples intervals and trend analysis

• Adequate oil cooling system, recommended operating temperature 50-60°C

• Oil condition monitoring device ea. moisture, ISO4406 cleanliness code, temperatures, pressure, etc.

• Oil conditioning unit in off-line (side stream) configuration, keep the oil clean & dry in optimum quality

Round table evaluation of the project of all involves parties.

Summaries of case study:

• Pre-treatment of the bio-lube before usage

• Filling bio-lube into oil system through three micron filter

• Maintaining moisture level below 800 mg/kg benefits the oil life time

• Achieved cleanliness level much better than recommended enhances reliability of the machine, less breakdowns

Dedicated CJC oil conditioning units:

1. Limited moisture ingress: dedicated unit is

HDU type utilizing B27/27 inserts and electric preheaters. Absorptions of moisture and retentions of particles and oxidation by-products.

2. Continuous (sea)water ingress: dedicated units are combination of Desorber type D10 or D30 and HDU type utilizing BLA27/27 inserts for retention of salt, dirt and oxidation by-products.
