由含硫原油生产Ⅰ类润滑油基础油中的问题

THE PROBLEMS IN THE PRODUCTION OF Ⅰ GROUP LUBE BASE OIL FROM SULFUR CRUDE

论述了由含硫原油生产Ⅰ类润滑油基础油的重要性,并介绍了由含硫原油生产Ⅰ类润滑油基础油加工过程中存在的问题,认为并非由含硫原油不能生产优质的基础油,而是我国现有的基础油生产装置是按加工大庆原油设计,不能完全适合加工含硫原油的需要,所以应适当改造。例如:增加丙烷脱沥青的溶剂比,用加氢补充精制代替白土精制等,此外,在含硫原油生产基础油时,对原油也应适当选择。

The importance of producing Ⅰ Group lube base oil from sulfur crude is discussed, pointing out some problems in the processing. It is thought it possible that sulfur crude is used to produce the premium base oil. Because the present facilities for base oil production in China are designed only for producing Daqing crude, it is not suitable for sulfur crude processing. So some renovations should be made, for example, increasing the solvent ratio of propane deasphalting; using hydrofinishing instead of clay treating; moreover, when producing base oil with sulfur crude, the crude has to be selected.
