Abstract
A process for the continuous dearomatization of a petroleum cut to produce a hydrocarbon-containing fluid with a very low sulphur content and very low aromatic compounds content, includes at least one stage of catalytic hydrogenation at a temperature between 80 and 180° C. and at a pressure between 50 and 160 bar. The stage of catalytic hydrogenation of the dearomatization process comprises several interchangeable reactors linked in series.
Claims12
A process for continuous dearomatization of a petroleum cut, comprising:
- (a) producing a hydrocarbon-containing fluid with a very low sulphur content and very low aromatic compounds content, at least one stage of catalytic hydrogenation at a temperature comprised between 80 and 180° C. and at a pressure comprised between 50 and 160 bar, and the stage of catalytic hydrogenation is made up of several interchangeable reactors linked in series;
- (b) isolating one of the reactors;
- (c) feeding a first one of two non-isolated reactors with the petroleum cut and feeding a second non-isolated reactor with effluent from the first non-isolated reactor;
- (d) regenerating the isolated reactor by replacement of the catalyst;
- (e) interrupting the feeding the second non-isolated reactor with effluent from the first non-isolated reactor;
- and
- (f) feeding the regenerated reactor with the effluent from the first non-isolated reactors of stage (c) and feeding the second non-isolated reactor of stage (c) with the effluent from the regenerated reactor.
