摘要/Abstract

摘要： 某石化公司精对苯二甲酸装置氧化干燥机运行3年来,在生产过程中频繁出现筒体内部积料、结垢,造成下料堵塞、运行周期短等问题,不仅影响装置长周期稳定运行,而且形成安全隐患。文章分析了干燥机内部结垢问题的发生原因,并逐项采取措施,减少了停车碱洗次数,节省了检修及能耗费用,达到了延长了干燥机连续运转周期的目的。

Abstract: The oxidation dryer in a PTA plant of certain petrochemical company has run for threeyears.In the production process,the inner buildup of the dryer＇s cylinder frequently occurs and the scaling is formed,resulting in feed opening blockage and short-term running.This not only affects the longterm operation,but also brings safety risks.This paper analyzes the causes for the scaling problems within the dryer and takes corresponding measures to reduce the number of alkaline wash,which saves the cost of maintenance and energy consumption and helps to achieve the goal of extending the dryer＇s cycle of operation.
