A method for high temperature - short-time - distillation of residual oil

摘要

A process for the high temperature - short-time - distillation of residual oils, is improved in such a way that of the gas / oil vapour - mixture of the mixer (1) a small residual fraction is obtained in a technically simple manner, in which the undesirable catalyst - pollutants (ccr, ni, v, asphaltenes) are mainly concentrated. For this purpose, the in a mixing reactor (1) generated gas / oil vapour - mixture in a column (17) is diluted with gas or water vapor to such an extent that, in the case of below 450°C, a high-boiling pollutant-containing fraction with an initial boiling point above 450°C. condensed and is drawn off, in which the pollutants are mainly concentrated. According to a further improvement of the roller which is not condensed product oil from column (17) of a fractionation - column (19), in which it is in a low-pollutant vacuum gas oil, as well as in a benzine / gas oil - fraction is broken down.
