Acid Gas Pipeline Charge Pump
Compass Model No.: EM200-PLG3M
Application: Acid gas pipeline charge pump
Customer Objective: Condense and pump acid gas from compressor/dehydrator for injection into sour gas gathering pipeline
Design Challenges:
■ Condense acid gas and generate suitable pressure to feed pump
■ Reliable safe operation
■ Minimize corrosion
■ Minimize fugitive and operator induced emissions
Compass Solution:
■ Use of a vertical style condenser with a horizontal accumulator vessel to minimize footprint and maximize the pressure below the bubble point
■ Dual pump packages
■ Double diaphragm reciprocating pump. Package with flange connections throughout with instrument isolation and venting.
