There are two processes in sodium sulfate production Chemical process Feed sodium chloride ( ≥ 97 ) and Sulfuric Acid ( H2SO4≥ 98 ) into Mannheim furnace, and the reactant is sodium sulfate
The process is as following
2NaCl + H2SO4 = Na2SO4+ 2HCl ↑- Q
Actually, the reaction is proceeded in two steps
NaCl + H2SO4 = NaHSO4 + HCl↑ + Q(1)
NaHSO4+ NaCl = Na2SO4+ 2HCl↑ - Q(2)
