Sulfur Plants: Simplify Tail Gas Clean Up, Lower Costs

Tougher regulations for emissions reductions require refiners to achieve ever higher sulfur recovery efficiency in their Sulfur Recovery Units. A classic solution is to use an amine-based tail gas clean up unit (TGCU) behind a Claus plant. A U.S. refiner, working on a major capacity increase, evaluated and selected an alternate technology. They selected the SUPERCLAUS® Tail Gas Clean Up Process, followed by a DynaWaveTM Wet Gas Scrubber. This system both meets stringent emission limits and provides advantages such as lower capital cost (TIC), smaller footprint and simple operation.
