Acid gas sweetening

The process of removing sour gas components like carbon dioxide (CO2) and hydrogen sulfide (H2S) from gas streams is known as acid gas removal or gas sweetening. These impurities must be eliminated due to issues like H2S toxicity, gas corrosiveness, low caloric value, potential environmental harm or other problems based on the application of the gas.

H2S removal

Sulfur types like H2S must be reduced to very low levels for safety, corrosion prevention and environmental protection as well as compatibility with downstream catalytic processes. Sulfur removal targets are often guided by global standards, such as the maximum allowable concentrations in natural gas transported via pipeline or in liquid form.

CO2 removal

Carbon dioxide (CO2) removal is required in many applications. Eastman AdapT solvents rely on the chemistry of the different amine-CO2 reactions to optimize the performance for each application. By selecting the type and concentration of the different amines, the CO2 removal rate and absorption capacity can be adapted.
