Mobil Rarus™ PE R- A/B/C/D 220
Ethylene compressor oil
Product Description
Mobil Rarus™ PE R-A, R-B, R-C and R-D 220 are viscous, colourless oils of ISO viscosity grade 220, specifically designed for the lubrication of very high pressure ethylene compressors. They are based on high purity, saturated hydrocarbon oils (white oils), supplemented with friction reducing and free-radical trap additives at adapted treat levels.
In the production of polyethylene, high-speed reciprocating compressors are used to compress ethylene gas to high pressures up to 3000bar. In these applications, the compressor lubricant can come in contact with the polyethylene in the polymerization process. Under these circumstances, the lubricating oil required must be of acceptable purity and be known not to modify the properties of the polyethylene.
Mobil Rarus PE R-A, R-B, R-C and R-D 220 provides good lubrication of the compressor cylinders and are compatible with the polyethylene process. They can be used to produce polyethylene where food contact can occur such as in food packaging. Mobil Rarus PE R-A, R-B, R-C and R-D 220 have good thermal and chemical stability. They can be used up to 3000 bars, according to injection system and temperature. Reactive gas components and impurities may react into the compressor itself, with formation of sludge, which may lead to lubrication failure. This is prevented by the additives, which also reduce bushing wear.
Mobil Rarus PE R-A 220 is recommended with highly reactive gas components.
Mobil Rarus PE R-B 220 is recommended for low reactivity impurities. Its additives display low volatility and migration. It is well suited for applications where there is fatty food contact
Mobil Rarus PE R-C 220 is recommended for intermediate reactivity gases.
Mobil Rarus PE R-D 220 is recommended for specific highly severe, high pressure applications.
Features and Benefits
Mobil Rarus PE R-A, R-B, R-C and R-D 220 are specifically engineered to help provide long and trouble-free compressor performance. Mobil Rarus PE R-A, R-B, R-C, and R-D 220 products are NSF H1 registered for food machinery “Lubricants for Incidental Contact with Food”, and meet the requirements for lubricants with incidental food contact (FDA 21 CFR 178.3570) and processing aids used in the production of olefin polymers intended for use in contact with food (FDA 21 CFR 177.1520)
