摘要
简要综述了HFC-134a生产过程中氟化氢的回收利用方法。分别介绍了吸附法、硫酸洗涤法、氢氟酸洗涤法等氟化氢直接回收利用工艺和氟化氢经过水吸收后制成氢氟酸后制取氟化钙、氟化镁、氟硅酸钾等衍生物盐类实现对氟化氢的再利用方法。HFC-134a生产过程中浪费的氟化氢得到有效地回收和利用,对氟资源的综合利用和环境保护具有积极意义。
Recycling method of hydrogen fluoride for the production of HFC - 134a was reviewed. Directly recycling, such as adsorption, hydrofluoric acid washing, sulfuric acid washing, and the use of derivatives, for example to produce calcium fluoride, magnesium fluoride, and potassium fluorosilicate were introduced, which provided important reference to the comprehensive utilization of fluoride resource and environment protection.
