Epcon Industrial Systems

The Challenge A leader in Latin America’s Chemical and  Petrochemical Industry  needed equipment to oxidize Hydrogen Sulphide and removal of SO 2 /SO 3 . The chemical plant generated large quantities of exhaust enriched with H 2 S, water vapor and air, which were costing the facility exorbitant amounts to properly dispose of . The company went out seeking the technical solutions and went to several  manufacturers  to locate the best possible technology. The Solution  Epcon has built several systems for Chemical companies for similar applications for removal of H 2 S and acid gases and used their prior experience to asses the appropriate technology. Epcon evaluated several technologies and decided on an Afterburner with Quench and Scrubber as the best solution for this application. Other types of oxidizers can be used, but based on their small flow and high heat release from VOC’s we chose an Afterburner. Epcon also designed and installed Quench ...

Afterburners and Thermal oxidizers rely on the process of combustion to oxidize VOC’s to the hydrocarbon units of CO 2 and H 2 O.   High temperatures and residence time, coupled with the proper amount of turbulence, allow this process to occur. Generally, these processes will be able to destroy over 95% of the VOC’s in the process gas.   In order to increase the VOC destruction efficiency, higher temperatures and longer retention times are necessary.   When the destruction efficiencies are this high, the only products of this reaction are water and Carbon Dioxide.   These off-gases can be released to the atmosphere, so there are no removal costs.   Another unique property of these incineration type devices is the ability to destroy both small particulate VOC’s as well as airborne VOC’s.   By combining an incinerator with other methods of VOC removal such as scrubbers , baghouse filters and boilers, 99%+ removal efficiency can be guaranteed.
