![]() The liquid thus collected is temporally stored at GA-SYS pressure and subsequently stored in a tank at low pressure. ![]() This mitigates the pressure drop in GA-SYS that consequently improves gas flow rate and augments the pipeline efficiency. Pigging of GA-SYS is often accomplished by using round-shaped or bullet-like pigs to strip out the condensed liquid. Gas accumulation and treatment plants are installed downstream of gathering systems (GA-SYS), where the liquid entrained in hydrocarbon-rich gases is prone to condense. It is estimated that just from methane emissions, 21,400 Mcf of gas can be recovered annually lost during pigging operations (EPA, 2005). 4.5.3 Personal decontamination and skincareġ Importance of Gas Recovery during Pigging operations.4.4 Maintenance, examination, and testing.4.3.4 Respiratory protective equipment (RPE).4.3.3 Personal protective equipment (PPE).4 Safety Measures during pigging and gas recovery.3 Gas Condensate Recovery System for pigging.2.3 Cooling System for Compressor and Vapors.2.2 Liquid Ring Compressors for Vapor Recovery.2 System for Gas Recovery during pigging.1 Importance of Gas Recovery during Pigging operations.
