Reduce CO2, H2S acid gases, and VOCs

There are inherent impurities in gas that not only accelerate the corrosion of pipelines and transmission control equipment—such as CO2, often deadly H2S acid gases, and volatile organic compounds (VOCs)—but also lower the heating value of the gas and contribute to fugitive emissions. These impurities must be removed prior to transmitting gas to a processing facility.

Experience optimal gas treatment

Our differentiating technology portfolio and expertise in process design and engineering provide the optimal gas treatment based on the parameters of your specific operation, including acid treatment, emissions control, glycol dehydration, natural gas liquid recovery, phase separation, and more. When you're planning your next front-end engineering and design (FEED) study, we can help you make the most of your natural gas recovery, treatment, and monetization.

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.
