硫酸分解氯化钾是生产Ｋ２ＳＯ４的主要方法，国际上具有代表性的为比利时的ＴＥＳＳＥＲＤＥＬＯＣＨＩＭＥ公司法、日本窒息法、日产法及台湾青上法，均采用曼海姆护法。目前国内硫酸钾生产约６０％采用台湾青上曼海姆反应炉。其原理： ２ＫＣＩ＋Ｈ２ＳＯ４－Ｋ２ＳＯ４＋２
Sulfuric acid decomposition Potassium chloride is the main method of producing K2SO4. The international representative companies are the TESSERDELOCHIME company law in Belgium, the Japan suffocation law, the Nissan law and the Taiwan Green Law, all adopting the Mannheim law. At present, about 60% of the potassium sulfate production in Taiwan adopts the Mannheim reactor at Qinghai. The principle: 2KCI + H2SO4-K2SO4 +2
