A breakthrough in flue gas cleanup, CO2 mitigation and H2S removal

摘要

SWAPSOL Corp. is developing commercial processes around a newly discovered chemical reaction verified to reduce hydrogen sulfide (H2S) below detectable levels while reacting with carbon dioxide (CO_2) to form water, sulfur and carsuls, a carbon-sulfur polymer. The Stenger-Wasas Process (SWAP) stands to fundamentally simplify sulfur removal technology as it consumes carbon dioxide in an exothermic reaction under relatively mild process conditions. The SWAP will have applications in landfill gas, sour gas, flue gas cleanup, Claus tail gas cleanup and may serve as an alternative to Claus technology. A related process allows for the destruction of waste hydrocarbons to form hydrogen sulfide and carsuls, providing a hydrogen sulfide source where it is not otherwise available. The primary reactions and variants have been independently verified and the chemical kinetics determined by a third party laboratory. Swapsol has filed US and international patent applications covering all aspects of the technology. Laboratory scale development of the various Swapsol processes is nearing completion and the company is exploring opportunities for pilot plant development programs with potential partners.
