Abstract
Method for optimising the production of middle distillate in a refinery, comprising at least one catalytic cracking unit (3) and at least one vacuum distillation unit (2, 4), the optimising operation consisting in:
- a) recycling (14) at least part of the cut obtained by fractionation of the effluents from catalytic cracking of an atmospheric and/or vacuum residue, distilling at at least 320° C. also called 320° C.+ cut in the feed of the said vacuum distillation unit (4),b) distilling the said cut under vacuum into at least two fractions, a fraction distilling between 320° C. and 550° C. called the HCOSV fraction, and a fraction distilling at at least 550° C. called the SSV fraction,c) sending the HCOSV fraction (18) thereby obtained to at least one of the distillate treatment units,d) and sending the SSV fraction (13) to the feed of the catalytic cracking unit (3), as such or after intermediate upgrading treatment.
