Cetus PAG

Premium performance PAG based synthetic compressor oil

(formerly known as LPG Compressor Oil)

Product description

Cetus PAG is a premium performance synthetic gas compressor lubricant formulated with Polyalkylene glycol and designed for use in enclosed pattern gas compressors where the crankcase and bearings operate in a hydrocarbon or chemical gas-filled atmosphere.

Cetus PAG is designed to maintain a high level of insolubility in this gas-filled environment helping avoid dilution and the significant drop in oil viscosity and lubricant protection this can cause, making it suitable for marine service on vessels carrying specialist liquefied gas cargoes. 

Customer benefits

• Helps minimise gas solubility in hydrocarbon and chemical gas-filled atmospheres, promoting improved compressor wear protection

• Robust formulation offering reliable, extended lubricant service life

• Helps deliver improved gas compressor operating efficiency and reduced foaming

• Designed for multi-gas service across a wide range of gases including vinyl chloride and butadiene

• Formulated to resist the dimerisation of butadiene and to prevent the generation of solid deposits

• Suitable for marine service on vessels carrying specialist liquefied gas cargoes

Applications

Cetus PAG is a high performance synthetic gas compressor lubricant, designed for enclosed pattern gas compressors for hydrocarbon and chemical gases, where the crankcase and bearings operate in a gas-filled atmosphere. Under these conditions the gas is readily soluble in mineral oil lubricants which, on dilution, suffer a significant drop in viscosity and lubricant performance. This problem can be overcome by using Cetus PAG in which the gases are much less soluble. It is particularly suitable for marine service on vessels carrying specialist liquefied gas cargoes.

Cetus PAG is used for the following gases:

• liquefied petroleum gases such as propane and butane

• liquefied natural gases such as methane and ethane

• hydrocarbon chemical gases such as ethylene, propylene and butylene

• chemical gases such as vinyl chloride, ammonia, butadiene

Cetus PAG is particularly suitable for marine service on vessels carrying specialist liquefied gas cargoes

Cetus PAG demonstrates some water and sulphide tolerance in pipeline compressor applications. The oil tolerates up to 4% water before hazing at 80 °C, and has been evaluated for corrosion resistance with 2.5% water

Cetus PAG does not affect common seal and gasket materials such as Nitrile Rubber (NBR) and fluorosilicones

Cetus PAG softens ordinary industrial paints. Two pack epoxy formulations are normally resistant  

Product maintenance and handling

• Cetus PAG should not be mixed with mineral oils
