Recover Gas from Pipeline Pigging Operations

The document outlines a method for recovering gas from pipeline pigging, where liquids are removed from gathering systems using pigs. It details the necessary equipment, such as vapor recovery compressors and storage tanks, and provides economic data showing that small recovery systems can be installed for approximately $24,000 with annual operating costs exceeding $1,000.

• Most of the vented gas can be recovered by installing a gas control system and recovering flash gas from pressurized liquid tanks, which adds gas to the sales line and reduces methane emissions.
• The average gas surplus per application is 21,400 thousand cubic feet per year. For a system gathering 3,000 barrels of condensate per pigging operation (occurring 30-40 times annually) at 200-300 psi, a small recovery system with an electric compressor costs $24,000 to install with annual O&M costs exceeding $1,000.
