Removal of acidic hydrogen sulphide (H2S) gas is a common contaminant in natural gas or CO2 processing applications, and particularly for biogas.
GLP has designed and installed many different H2S removal systems tailored to each customer’s requirements.
H2S is typically removed with the following technologies:
– Wet scrubbing with water or alkaline solutions
– Dry absorption with mixed metal oxides (typically iron or zinc oxides)
GLP works with customers to specify the most suitable process technology for each requirement including desired H2S removal efficiency and available utilities.
