H2S POLISHING SKID
​The H₂S Polishing Skid is part of ABA’s integrated biomethane product line, engineered to condition raw or scrubbed biogas into high-quality, pipeline-ready biomethane. All wetted parts are constructed from stainless steel to ensure long-term durability, corrosion resistance, and stable operation in demanding biogas environments.

Configured in a proven lead-and-lag arrangement, the system delivers continuous H₂S reduction to below 5 ppm, enabling uninterrupted operation while allowing media change-out without process downtime. This configuration provides reliable protection for compressors, membrane separation systems, and other critical downstream equipment.
​
Designed for seamless integration within ABA’s biomethane upgrading trains, the polishing skid supports consistent gas quality, operational resilience, and long-term asset protection across a wide range of biogas applications.
