针对鞍钢35000m3/h空分设备运行后分子筛纯化系统存在的不足,通过采取延长分子筛吸附器的并行时间、减小分子筛吸附器的升压速度和改进分子筛蒸汽加热器系统的措施,实现了分子筛纯化系统和整个空分设备长期稳定运行。
Aiming at the deficiencies of the molecular sieve purification system after the operation of 35000m3 / h air separation plant in Ansteel, the molecular sieve purification was achieved by adopting the methods of extending the parallel time of the molecular sieve adsorber, reducing the step-up rate of the molecular sieve adsorber and improving the molecular sieve steam heater system Long-term stable operation of the system and the entire air separation plant.
