1. A compression system, comprising:

  • a compressor;

    a process fluid source containing a process fluid;

    a lubricant source;

    a process fluid pump;

    a lubricant inlet line fluidly connecting the lubricant source to the compressor and the process fluid pump, wherein the lubricant inlet line provides a usable lubricant to the compressor and the process fluid pump from the lubricant source;

    a separation device fluidly connected with the lubricant source, the process fluid source, the compressor, and the process fluid pump, wherein a portion of the usable lubricant mixes with the process fluid, and the process fluid is separated such that a gaseous portion of the process fluid is channeled to the compressor and a liquid portion of the process fluid is channeled to the process fluid pump;

    a lubricant recycling line fluidly connected to the lubricant inlet line, the compressor, and the process fluid pump, wherein a used lubricant is discharged from the compressor and the process fluid pump into the lubricant recycling line, and the lubricant recycling line provides a recycled lubricant to the lubricant inlet line;

    a lubricant filter fluidly connected to the lubricant recycling line, wherein the lubricant filter filters the used lubricant;

    a lubricant pump fluidly connected to the lubricant recycling line, wherein the lubricant pump pumps the used lubricant through the lubricant recycling line; and

    a lubricant cooler fluidly connected to the lubricant recycling line, wherein the lubricant cooler cools the used lubricant.
