Application of synthetic lubricating oil in processing and hydrocarbon gas presses

1. Hydrocarbon and process gas compressor lubricants Historically, hydrocarbon, chemical processing and inert industrial gas compressors have used traditional mineral oil-based lubricants. However, mineral oil cannot meet the needs of many modern rotary compressor designs and other complex applications. A typical gas processing application is at an outflow temperature of 80-1100C and a pressure of 7-70barg.
