为了使分子筛脱水装置能高效平稳地运行，通过分析以前设计中存在的流程不合理、设备能耗高、设备本体损坏等不足，在新工程中针对以上问题进行研究分析，找出原来不足的原因并提出具体的解决方案。最终通过优化再生气的工艺流程，改变再生气管线和再生气冷却器以及避免再生气压缩机材料的H₂S腐蚀，改变分子筛脱水塔底部支撑的结构形式，保证工艺装置的正常运行。同时改变再生气加热炉的结构形式，提高加热炉的热效率，大大降低装置的能耗，达到节能环保的目的。

Analyzed are such shortages existing in previous engineering design of molecular sieve dehydration unit as unreasonable technological process, high energy consumption and equipment damage, identified are causes resulting in such shortages and proposed are specific solutions. Optimized is technological process of regeneration gas, changed are materials of regeneration gas pipelines and cooler as well as regeneration gas compressor so as to avoid corrosion of H2S on these equipments, changed is the bottom support structure of molecular sieve dehydration tower so as to ensure normal operation of process unit, and changed is the structure of regeneration gas heating furnace so as to improve thermal efficiency of the heating furnace, which reduces energy consumption of the furnace greatly and achieved is the purpose of energy conservation and environmental protection.
