The process gas carrying a large amount of oil needs to go through separation, coarse filtration separation, and fine filtration separation to make the oil content in the process gas lower than 1 PPM. If the oil in the process gas cannot be effectively separated, it will cause the screw machine system to lack oil in the long term, affecting the service life of the screw machine. The oil in the process gas will also affect the subsequent processing of the process gas.
