This practice, reported by the Phillips Enron Gas Pipeline Group, can recover approximately 12,000 cubic feet of gas per shutdown event. For a station with six compressors experiencing 42 shutdowns annually, the estimated savings are 500,000 cubic feet of methane per year. Capital costs for necessary piping and valves are estimated between $900 and $1,600 per compressor, with a projected payback period of less than three years based on a gas price of $3 per thousand cubic feet.","ai_generated":true,"unit":"catf-000549#summary","date_modified":"2026-10-23"},"key_insights":[],"climate_tags":["methane emissions"],"geography_discussed":[],"frame_perspective":[],"analysis_type":["technical assessment","economic analysis"]}]}
