Sulfuric Acid | Wet gas Sulfuric Acid (WSA)

The WSA process is a wet gas catalytic process. The concentrated sulfuric acid is produced by condensation from a wet process gas. Drying of the process gas prior to treatment in a WSA plant, therefore, becomes superfluous, hence generation of wastewater and loss of sulfur are avoided. The purpose of the first step in the process is to produce an SO2 gas at the operating temperature of the oxidation catalyst in the SO2 converter. If the sulfur in the feed is SO2, only a simple preheating is required.

Coker naphtha hydrotreating technology

Coker naphtha places extraordinary demands on hydrotreating processes. These difficult-to-process streams often contain high levels of silica, which decrease HDN catalyst activity. Complications can also arise because they have high concentrations of conjugated di-olefins that tend to polymerize, as well as olefins that immediately saturate and release heat that challenges temperature control.
