Aspen Tech acquires Sulsim software

Mary Page Bailey

Aspen Technology, Inc. (Burlington, Mass.;, a provider of software and services to the process industries, announced it has acquired the Sulsim sulfur simulation software from Sulphur Experts Inc.(  The Sulsim sulfur-recovery product has been used by the world’s leading energy companies for over 25 years. With Sulsim, process engineers can model the reaction furnace, reactors, incinerator, and other related operations of sulfur recovery plants accurately.  Because this is the last step in acid-gas cleaning, accurate modeling is essential since any disturbance will bottleneck the process flow causing reduced throughput and heavy losses. Sulsim technology will allow AspenTech customers for the first time to optimize acid-gas cleaning and sulfur-recovery design and operations together.  Potential benefits for refiners and gas processors from using a single engineering environment include improved efficiency, capital savings, safer operation, and minimized operating costs. Terms of the transaction were not disclosed.
