针对遂宁轻烃回收装置脱乙烷塔体系目前存在塔底温度控制不稳定,塔底液化气易汽化,回流泵操作困难等问题进行分析与讨论,寻找优化操作方案,从而提高回收率。
In view of the problems of instable bottom temperature control, easy vaporization of bottom liquefied gas and difficult operation of reflux pump, the de-ethane tower system of light hydrocarbon recovery unit in Suining currently has the problems of difficult operation and operation of the reflux pump. The optimized operation scheme is sought to improve the recovery rate.
