Contribution to Production of Basic Oils by Hydrocracking

Abstract The largest part of contemporary lubricants has been obtained by different procedures of fabrication and processing of crude oil, mainly on the paraffin basis. Many contemporary plants for oil production have been designed and built a few years ago. The successful implementation of the existing technology in this field gives opportunities for optimisation of the existing technology and/or change of the existing production process with introduction of the new regime of work. In accordance with the results of laboratory and exploitation investigations in crude oil refineries and production of basic oils the possibility for reduction of the process of production of the basic oils, excluding vacuum distilling plant under alternation of regime of work of hydro-cracking has been examined. Hydro-cracking has been designed for production of fuels with total conversion of charge. Under changed conditions it is necessary to work with the residue, which has the same distilling interval as the distilling interval of the charge, and serves for production of basic oils.
