The SWSPlus Process

SWSPlusSM is a patented two-column sour water management technology, where the gases from a Sour Water Stripper (SWS) are separated into acid gases (H2S and CO2) in one stream and a salable ammonia (NH3) in another, that can be used as a simple addition to existing refinery equipment. The technology is designed and proven to increase the overall refinery margin by debottlenecking sulfur recovery unit operation and generating an additional revenue stream. Find out more and learn about our “Bolt-On Absorber” for SWSPlus use for maximizing refinery margins. 

  • Expand the capacity of your Sulfur Plant
  • Make blue ammonia from a waste stream
  • Reduce SOx, NOx, and PM emissions

Commercially Proven Technology

                                         

For every ton of NH3 removed, approximately 3 tons of hydrogen sulfide can be processed in the downstream Sulfur Recovery Unit (SRU). Removing NH3 allows for effective debottlenecking of the SRU train and increased reliability.
