摘要
导热油长期使用后,导热油系统管线及反应釜夹套内易形成大量油泥、积炭等污垢,影响系统正常使用,需及时进行清洗。针对以上问题,通过斑点试验和离心试验进行了分散剂加量考察,确定了清洗油添加剂配方为质量比2%分散剂+98%清洗油;以此清洗油配方进行导热油系统清洗,采用分光光度法监测清洗油中油泥含量,建立了导热油清洗效果的评价方法,并对导热油系统清洗过程进行了跟踪评价,结果显示清洗效果良好。
After long-term use of heat-transfer oil,oil sludge and coke were formed in the heat-transfer oil pipe and reaction kettles,affecting the efficiency of heat-transfer.Aiming at these problems,the dispersant dosage was investigated through spot test and centrifuge test.The heat-transfer oil system was cleaned using the cleanout oil consisting of 2% dispersant and 98% base oil.Sludge amount was detected through spectrophotometry method and the evaluating method of heat-transfer oil system was established.The follow-up evaluation result of the cleaning process showed that the cleaning effect is good.
