氢气除水干燥工艺改进

Improvement in hydrogen drying process

烧碱装置原有氢气输送工艺夹带的水分,影响下游双氧水生产的稳定运行。通过工艺改进,在压缩机进口管道上增加氢气预冷器,减少了氢气中的水含量,保证双氧水车间氢化效率稳定,稳定双氧水车间运行,保障装置的稳产高产。

The moisture in the original hydrogen transportation process of caustic soda plant affected the stable operation of downstream hydrogen peroxide production.Process improvement were made:a hydrogen precooler was added to the inlet pipe of the compressor.After the improvement,the water content of hydrogen reduced.Thus,the hydrogen efficiency of hydrogen peroxide workshop was stable,the operation of hydrogen peroxide workshop was stable,and the stable production at high yield was guaranteed.
