Catalog excerpts

Reaction furnaces Acid gas (main) burners In-line heaters Tail gas incinerators Waste heat boilers (Kettle and Steam Drum circulation types) Packaged units are available complete with controls and burner management control systems > Several technologies exist for removal of sulphur compounds from acid or sour gases which arise in the oil refining, gas processing and other process industries. The sour feed gas is treated in an amine scrubber in which the acid gases are absorbed in a basic amine solution to produce sweet (sulphur free) sales gas and an off gas stream (tail gas) rich in...
