概述制备干燥气体(露点-60℃)供空分系统的冷设备解冻加温,是空分解冻工艺的主要任务。为此,历来将湿空气加工成干气,供解冻加温之用。早期用固体烧碱为干燥剂,现代使用硅胶铝胶,分子筛等吸附解冻工质中的水分。这些干燥剂,除固体烧碱外,其他都以再生处理循环使用。为完成上述要求,解冻工艺流程就复杂些。如 KDON Overview Preparation of dry gas (dew point -60 ℃) for the air separation system of cold equipment thawing heating, air separation and thawing process is the main task. To this end, the wet air has always been processed into dry gas for thawing heating purposes. Early use of solid caustic soda as a desiccant, the modern use of aluminum gel silica gel, molecular sieve adsorption and other work in the water. These desiccants, except for solid caustic soda, are recycled for recycling. To complete the above requirements, the thawing process is more complex. Such as KDON
