Using SELEXOL™ Solvent for Multiple Applications A Discussion of Flow Schemes and Case Studies

摘要

SELEXOL™ Solvent is a physical solvent that has been successfully used for many different applications around the world, including acid gas (CO_2 H_2S, COS and mercaptans) removal from gas streams and hydrocarbon dewpoint control. This paper will describe the properties and versatility of SELEXOL Solvent in a variety of flow schemes providing energy efficient gas treating in a range of applications - ammonia, gasification, natural gas treating (CO_2/H_2S and organic sulphur) and hydrocarbon dew point control. Design guidelines and performance limitations for SELEXOL Solvent are discussed. Most publications on SELEXOL solvent are focused on syngas treating from gasification. This paper provides design and operations information for applications not typically found in earlier studies.
