Basics Of Operation And Application Of Oil Flooded Rotary Screw Compressors.

Tutorialpg. 147-156Rotary screw compressors are widely used today in chemical and petrochemical refining, gas processing, and in the oil patch. Common applications include refrigeration using hydrocarbons, hydrofluorocarbons (HFCs), and ammonia refrigerants, vapor recover, gas gathering, and compression of fuel gas, natural gas, landfill gas, tail gas, CO2, and helium. Simple in concept, the screw geometry is sufficiently difficult to visualize that many people using screws today have only a vague idea how the actually work. An understanding of the basics of their operation will help in applying them correctly, avoiding nuisance problems in operation, and achieving the best overall system designs
