Natural Gas & Propane Applications

Sour Gas Treatment: Sulfolane is used during the pre-treatment process of natural gas. While most natural gas requires minimal treatment, sour natural gas requires a chemical absorption process. Although various formulated amine solvents are effective in removing H2S, CO2, and COS, the addition of Sulfolane provides mercaptan and other organic sulfur compound removal capabilities. Sulfolane also acts as a foam inhibitor, increasing process reliability.

Petroleum and Refinery Applications

Aromatics Extraction: Combined with process technology offered by Axens and UOP, Sulfolane-W can be used to separate BTX (benzene, toluene, and xylene) aromatic hydrocarbons from refinery reformate.
