Acidic oil refinery tail gas contains large amounts of H2S, if a large number of release, may be harmful to human health and the environment.

For the claus sulfur recovery of tail gas treatment device, the sulfur compounds in sulfur recovery unit exhaust (SO2, COS, CS2 and Sx) by hydrotreating for H2S.Claus tail gas of sulfur compounds can also through the wet sulphuric acid (WSA) process into sulfuric acid.

There are many oil refineries faced to refineries to improve efficiency and reduce emissions that the grim problem of double.Top line verified by commercial fuel gas hydrotreating technology can remove sulfur compounds from usually difficult to remove the dirty oil refinery fuel gas flow, allowing the two problems solved.

Stripper overhead accumulator and washing operation of acidic wastewater containing impurities, the most obvious is that sulfur compounds and ammonia, must remove the impurities in the water to be reused in the refinery.
