摘要
TBA精制系统开车运行后出现闪蒸罐再沸器因结垢堵塞导致运行周期短的问题,通过对结垢物质进行分析研究,采用添加20Y60分散剂的处理措施,有效延长了再沸器运行周期,提升了闪蒸罐温度,减少了重组分排放量,减少了危废处理费用。
After the start-up of TBA distillation system,fouling caused short run-lengthen of reboiler of flash tank.Through the analysis and study of foulant,20Y60 dispersant was added into the feed of flash tank.And through application of 20Y60 dispersant run-lengthen of reboiler extends,and the bottom temperature of flash tank can increase so the bottom discharge and hazardous waste treatment cost decrease.
