Gas Treatment

Facilitating the recovery, treatment, and monetization of natural gas

Gas treatment facility

There are inherent impurities in gas that not only accelerate the corrosion of pipelines and transmission control equipment but lower the heating value of the gas. These impurities must be removed prior to transmitting gas to a processing facility.

Our differentiating technology portfolio and expertise in process design and engineering provide the optimal gas treatment based on the parameters of your specific operation. When you're planning your next front-end engineering and design (FEED) study, we can help you make the most of your opportunity.

Services from concept through operations
Our global network of experts provides a wide range of services, including conceptual design, project execution, precommissioning, commissioning, operations, remote monitoring, and technical support.

Acid Gas Treatment

Separate CO₂ and H₂S from saleable natural gas streams with gas sweetening processes.

Use industry-leading technologies for CO₂ and H₂S removal

Acid gas treatment and removal technologies separate sour gases—highly corrosive CO2 and often deadly H2S acid gases—from saleable natural gas streams in a process known as gas sweetening. Once removed, the CO2 and H2S are usually vented in low concentrations, flared, and then reinjected or otherwise properly disposed of. Larger concentrations of CO2 are recovered and repurposed for enhanced oil recovery applications.
