Complete elimination of hydrogen sulfide levels
Over 98% reduction in outage time
No personnel exposure to hazardous materials
No additional disposal expense
Designed for instantaneous and permanent elimination of hydrogen sulfide present in refining and other process equipment. The most efficient abatement product on the market capable of removing 3 moles of sulfide to 1 mole of active chemical.
The initial H2S readings from the Sour Naphtha tank exceeded 40,000 ppm (4.0%). A 50% FQE H2S in water mixture was prepared and circulated in the tank. The tank bottom was circulated first to eliminate the hydrogen sulfide present in the residual naphtha.
Following the neutralizing of naphtha, the aqueous phase was atomized through the tank airspace successfully eliminating the airborne hydrogen sulfide. The tank was a fixed roof, 100’ diameter tank containing approximately 30,000 bbls of residual naphtha. The hydrogen sulfide elimination was completed in less than 2 hours with the H2S being reported at 0 ppm. The liquid was allowed to phase separate for 1 hour and the aqueous phase containing the sulfide reaction product decanted from the tank.
Typically, this process is conducted by the slow removal of vapor by thermal oxidation (internal combustion engine) over a 2 – 3 day period of time resulting in extra cost and lost time pending process completion.
