Abstract: The present invention concerns a process for the production of light olefins and BTX using a catalytic cracking unit, NCC, processing a naphtha type feed, and an aromatics complex. It can be used to exploit the synergies between these two units. The thermal balance of the NCC, which is intrinsically deficient in coke, is resolved by the optimal use of heat from the reforming furnaces in order to preheat the feed for the NCC, and by introducing at least a portion of the raffinate obtained from the aromatics complex as a mixture with the naphtha.
