摘要:

针对异戊烷酸值偏高的问题，通过异戊烷与碱反应，分析了碱罐中的晶状混合物成分，查找出导致异戊烷产品酸值偏高的主要原因是罐区充压干气中的CO2在轻油中有一定的溶解量，并最终研究出了一种简单可行的降低异戊烷酸值的方法——精馏法，并成功地应用于异戊烷生产装置改造中，取得了良好的效果。

Abstract:

According to the problem which i-pentane's acidity was high, a series of researches were made by reacting with alkali, researching the compositions of mixture lens which was took out from the alkali pot, and rectifying to reduce i-pentane's acidity. A bri
