Cetus PAG
Premium performance PAG based synthetic compressor oil (formerly known as LPG Compressor Oil)
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.
Εφαρμογές
- 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 resistantT
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
Approvals
- VGP Compliant and listed by the US Environmental Protection Agency as approved Environmentally Acceptable Lubricants
Performance
- Cetus PAG meets the performance requirements of Linde for general service gas compression including ammonia, vinyl chloride and butadiene
- Cetus PAG meets the requirements of Sulzer Burckhardt AG, Winterthur for use in their K-type gas cargo compressors for general LPG/LNG service and for ammonia, vinyl chloride, butadiene
- Cetus PAG meets the requirements of Howden Compressors Ltd, for use in refrigeration compressors operating with propane and propylene at discharge pressures exceeding 7 kg/cm²
- Cetus PAG remains approved and listed under the old name of LPG Compressor Oil
