摘　　要：针对新疆独山子石化公司TBN250高碱性环烷酸钙润滑油添加剂生产中存在脱水难的问题,对原工艺进行了改进.在原有生产工艺的基础上增加了回流脱水工序,取得了较好的脱水效果,对产品质量无不利影响.该方法可将添加剂中的水分脱除至0.1%以下,脱水时间从原工艺的2～3天,缩短至2h左右,缩短了润滑油添加剂生产周期,同时还降低了生产能耗.A process improvement of the production of highly basic calcium additive （TBN 250） for lube oil was carried out to solve the difficulty in dehydration. naphthenate A refluxing procedure was added to enhance the efficiency of dehydration without side effect on product quality. Water in additive was effectively removed to below 0.1% by this improved process in about 2h instead of 2--3 days with the original process. The production cycle was much shorter and energy consumption reduced.
