Fluid recovery system

A fluid recovery system comprising:

• a reciprocating compressor, a vapor recovery unit, a control system, a compressor frame vent line, a packing case vent line, a main vapor recovery unit inlet line, and a discharge line, the packing case vent line comprising a valve;
• the vapor recovery unit comprising a vapor recovery vessel and a vapor recovery compressor comprising a motor, the main vapor recovery unit inlet line being fluidly connected to the vapor recovery vessel;
• the reciprocating compressor being fluidly connected to the compressor frame vent line and the packing case vent line;
• the packing case vent line valve being adapted to regulate a flow of packing case vapor through the vent line to the main vapor recovery unit inlet line;
• the compressor frame vent line being adapted to permit a flow of blow-by gas through the compressor frame vent line to the main vapor recovery unit inlet line;
• the control system being adapted to monitor a vapor recovery vessel input pressure and control the vapor recovery compressor;
• and
• the control system being further adapted to control a vapor recovery vessel output to the discharge line, the discharge line being fluidly connected to the reciprocating compressor inlet vessel, the reciprocating compressor inlet vessel fluidly connected to the reciprocating compressor.
