Sour Gas Treatment

Sour gas treatment involves using amine solutions to remove acid gases such as hydrogen sulfide (H2S) and carbon dioxide (CO2) from hydrocarbon gas in refineries and gas plants.

An ideal version of sour gas treatment completely separates acid gases from hydrocarbons in the gas stream, so that the treated gas contains no acid gases, and the acid gases contain no hydrocarbons.

The treated, sweetened gas moves on to the refinery fuel gas system, while the amine solution is further treated to remove the H2S and CO2. These acid gases are sent to the sulfur recovery unit for processing into sulfur.

Our solutions for this application include a combined dispersive ultraviolet optical bench and non-dispersive infrared sensor, providing the fast-response measurements required for control of the sour gas treatment. Our experience in this application enhances safety for technicians and sample handlers.

  • Application +


    Feed-forward, amine efficiency

    Feed gas analysis requires a real-time quantification of the combustion components, so an analysis time of under 5 seconds is essential. Balancing the combustion air ensures an efficient process, which is of great importance, specifically for upset situations.

    SO2 removal efficiency

    The efficient removal of SO2 from the process gas stream is essential to prevent contamination and reduce harmful emissions.
