摘要
1.0Mt/a催化裂化装置为提高富液闪蒸效果,2010年液化气脱硫单元实施了技术改造。但改造后导致酸性气中的烃含量偏高,使酸性气无法被回收利用。文中分析了酸性气中烃含量升高的原因,并采取了调整闪蒸温度、闪蒸时间等措施降低烃含量,收到了实际效果。
The 1.0 Mt/a catalytic cracking unit implemented technical modification to the liquefied gas desulfurization unit in 2010 to improve rich-gas flashing effect. However , the hydrocarbon content in the acidic gas was high after the modification , causing unable to recycle the acidic acid. The causes for the high content of hydrocarbon in acidic gas were analyzed , measures such as regulating flashing temperature and flashing time were adopted , and actual effect has been obtained.
