空分设备运行节能降耗的优化措施及操作实践

Optimization measures and operation practice of energy saving and consumption reduction in air separation plant operation

河南某公司制氧厂为争取生产成本最小化,结合实际工作经验,从循环水泵的变频改造、总循环水量的增减、分子筛纯化系统预冷吹节能法、降低空压机排气压力等四个方面,介绍空分设备节能降耗的具体措施和取得的效果。

in order to minimize the production cost,combined with practical work experience,the oxygen plant of Henan Yuguang Gold lead Co.,Ltd.introduces the specific measures and results of energy saving and consumption reduction of air separation equipment from four aspects:frequency conversion transformation of circulating water pump,increase or decrease of total circulating water volume,precooling blowing energy-saving method of molecular sieve purification system and reducing the exhaust pressure of air compressor.
