摘要
剖析了C_5石油树脂间歇精制工艺存在的问题及改进的必要性,采用降膜蒸发器开发了连续化精制新工艺。改进后的工艺与原工艺比较,缩短了精制时间,提高了产品质量和控制水平,降低了劳动强度,改善了操作环境。
New continuous purification process has been developed. Compared with the existing process, the improved process is characterized by shorter purification period, better product quality and control level.
