H2S & CO2 Removal
H2S, CO2 and other contaminants are commonly found in natural gas streams. H2S is an extremely toxic and corrosive gas that provides the serious risk to human life in the case of equipment and/or pipeline leaks and drastically shortens equipment life due to accelerated corrosion in carbon steel materials. CO2 drastically reduces the heating value of natural gas; and, where CO2 concentrations exceed 2-3 mol%, the natural gas becomes un-marketable. CO2, when combined with water, forms a carbonic acid that is extremely corrosive to carbon steel materials.
Several methods can be employed to reduce the content of H2S and/or CO2 in natural gas. KOCKEN Sistemas de Energia Inc. applies the most common using a variety of liquid solvents including:
- Liquid Solvents
- MEA
- DEA
- MDEA
- DGA
- Specialty Solvents
