摘要
针对中海沥青股份有限公司0.3 Mt/a润滑油糠醛精制装置在开工过程中出现的一些影响产品质量和加工能力的瓶颈问题,分析了原因,并采取优化原料换热流程、降低抽提塔中段循环量、注缓蚀剂等改进措施,使装置在较短时间内开工正常,精制油收率及质量指标均达到设计要求。
Problems in the start up of the 0.3 Mt/a lube oil furfural refining unit of Zhonghai Asphalt Company were reviewed and analyzed, such as high feed inlet temperature of deaerator led to feed loss,high bottom reflux of extractor caused low refined oil yield, the oxidation of furfural and feed resulted in the bad color of refined oil and etc. Proper countermeasures were adopted to optimize the operation including the improvement in feed heat exchange, reducing the reflux of extractor and the injection of corrosion inhibitor,the start up was successful in a short period of time. Since then the yield and quality of the refined oil well met the design requirements.
