Aspen Technology Inc. has acquired Sulsim sulfur simulation software from Sulphur Experts, Aspen Technology said April 1.

Sulfur recovery is performed in almost every refinery and gas plant processing high sulfur feeds. Regulatory policies require the removal of sulfur from gas produced by these plants. With Sulsim, process engineers can model the reaction furnace, reactors, incinerator and other related operations of sulfur recovery plants more accurately, according to Aspen Technology.  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.

AspenTech’s Aspen HYSYS software already provides modeling capabilities for process equipment and for acid gas cleaning systems. Sulsim technology will allow AspenTech customers 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.
