针对克石化炼厂气回收系统负荷有限的现状,通过研究富氢装置排放气体组成分析,采用增加高压加氢装置高分气膜分离系统、全厂低分气脱硫系统、重整PSA尾气回收系统等多项措施,不仅有效地利用全厂瓦斯,避免了火炬的燃烧和浪费,还回收大量的氢气供加氢装置使用,达到很好的节能减排效果。
In view of the limited load status of the gas recovery system in the petrochemical refinery, by analyzing the composition of the exhaust gas in the hydrogen-rich plant, the high-pressure membrane separation system of high-pressure hydrogenation unit, the low-gas desulfurization system of the whole plant and the tail gas recovery system of PSA And many other measures, not only effective use of the entire plant gas, to avoid the torch burning and waste, but also recycling a large number of hydrogen for hydrogenation unit to achieve good energy-saving emission reduction effect.
