The wet sulfuric acid process (WSA process) is one of the key gas desulfurization processes on the market today. Since the Danish catalyst company Haldor Topsoe introduced and patented this technology in the late 1980s, it has been recognised as an efficient process for recovering sulfur from various process gasses in the form of commercial quality sulfuric acid (H2SO4), with simultaneous production of high pressure steam. The WSA process is applied in all industries where removal of sulfur is an issue. The wet catalysis process is especially suited for processing one or more sulfur containing streams such as.: *H2S gas from e.g. amine gas treating unit *Off-gas from sour water stripper (SWS gas) *Off-gas from Rectisol *Spent acid from an Alkylation unit *Claus process tail gas *Heavy residue or petcoke-fired utility boiler off-gas *Boiler flue gases from various processes SNOX flue gas desulfurisation *Metallurgical process gas *Production of sulfuric acid == The process == 800px ;The main reactions in the WSA process *Combustion: 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「wet sulfuric acid process」の詳細全文を読む スポンサード リンク
