400 HP Screw Compressor Package (Custom Unit)

Compass Model No.: WK400-SS-PDR25

Application: Mine Vent Gas Recovery

Location: Green River, Wyoming

Design Challenges: The customer required removal of explosive mine gas which was previously vented into the atmosphere. The mine gas included a certain percentage of 02 which needed to be accurately monitored to ensure the compressor operated outside of explosive limits.

Compass Solution: Compass Compression custom designed a 400 HP rotary screw compressor package pulling vacuum with a discharge pressure of 70 psig and special 02 sensing equipment. Once the gas was recovered it was used as plant fuel gas for burners on process equipment.
