Manufacturer's description

Mobil Rarus PE KPL 220 is an ISO VG 220 ethylene and co-monomer compressor oil based on a patented combination of high-purity, saturated hydrocarbon oils supplemented with friction-reducing and free-radical trap additives at adapted treat levels. It is specifically designed for the lubrication of very high-pressure ethylene and co-monomer hyper compressors, usable up to 3800 bar depending on the oil injection system and temperature, with viscosity and composition tailored for the highest pressures found in ethylene compressors for LDPE production. The oil keeps viscosity increase under extreme pressure low enough to ensure adequate lubricant flow, while its additives prevent early polymerisation of reactive gas components and impurities inside the compressor, which could otherwise cause deposits and lubrication failure. It also mitigates friction losses and can improve cylinder packing life, reducing the frequency of maintenance shutdowns. Its low-reactivity, high-purity, low-polarity components do not interfere with polymerisation reactions and avoid discoloration or odour in the finished polymer, making the oil suitable for polymers used in food packaging and electrical insulation applications. Mobil Rarus PE KPL 220 is registered to NSF H1 and meets or exceeds FDA 21 CFR 178.3570 and Burckhardt VSB 1001180, including Burckhardt Pumpability certificates for hyper compressors up to 3850 bar and 3896 bar at a minimum temperature of 70°C. Typical properties include ISO VG 220 grade, kinematic viscosity of 210 mm²/s at 40°C, flash point of 270°C, pour point of -12°C, and total acid number of 0.5 mg KOH/g.

Applications

• Mobil Rarus PE KPL 220 is specifically designed for the lubrication of very high pressure ethylene and co-monomers compressors. It may be used up to 3800 bars, according to oil injection system and temperature. Mobil Rarus PE KPL 220 is formulated for the most demanding applications. Its viscosity and composition are tailored for the highest pressures found in ethylene compressors for LDPE production. The viscosity increase under the highest pressures remains low enough to ensure an adequate flow of lubricating oil. Additives also prevent the early polymerization of reactive gas components and impurities into the compressor itself, which may lead to formation of deposits, and eventually to lubrication failure. Additives also mitigate friction losses and may improve cylinder packing life. As a result, shutdowns for maintenance, are less frequent. This product meets or exceeds the requirements of: • Burckhardt Pumpability certificate for hyper compressors for pressures up to 3850 bars at a minimum temperature of 70 °C for a pump speed of 164 rpm • Burckhardt Pumpability certificate for hyper compressors for pressures up to 3896 bar at a minimum temperature of 70 °C for a pump speed of 250 rpm

Performance & benefits

• Processing aids such as lubricants may be applied to USP <661.1> polymers but are not specified by the chapter. • Low reactivity components. Do not interfere with polymerization reactions. • High purity components. Do not induce any discoloration or odor in the final polymer. • Components approved for food contact. Suitable for the manufacture of polymers for food packaging containers. • Low polarity. Suitable in the manufacture of polymers for electrical insulation and thin sheets (plastic bags). • High pumpability. Adequate flow of lubricating oil and improved cylinder lubrication at very high pressure. • Reduced maintenance shutdowns. • Outstanding anti-wear and corrosion protection enhances equipment life and performance.

Standards & approvals

• NSF H1

  NSF H1 — incidental food contact lubricant

  The NSF registration for lubricants that may incidentally touch food during production. The formulation is limited to permitted substances, and the contact stays incidental, not intended.

• FDA 21 CFR 178.3570

  FDA 21 CFR 178.3570 — lubricants with incidental food contact

  The article of the US regulation listing the substances permitted in a lubricant that may incidentally contact food. It is the legal basis an NSF H1 registration rests on.
