Abstract: The present invention describes a process for heating the reboiler of the propane/propylene separation column situated downstream of an FCC unit and fed with the C3 cut from said FCC unit, a process consisting of heating the water in a hot water circuit by means of one or more process fluids originating from units placed upstream and/or downstream of the FCC unit and called hot fluids, one of these fluids being constituted by the overhead vapours from the fractionation column connected to the mild hydrocracking unit.

Abstract: The invention relates to a process for converting used tyres to obtain carbon black, comprising the following steps:

a) sending a solid feedstock based on used tires to a reaction zone in the presence of a liquid solvent to obtain a vapor effluent and a first liquid effluent comprising the carbon black,
b) sending the liquid effluent to a filtration and washing unit to obtain a filtered and washed carbon black cake and a second liquid effluent;
c) sending said vapor effluent and the second liquid effluent to a fractionation zone to obtain at least one hydrocarbon cut;
d) sending said hydrocarbon cut obtained at the end of step c) to the reaction zone as liquid solvent of step a);
e) drying the carbon black cake.

Abstract: The invention relates to a process for converting a plastic feedstock and for converting used tyres to obtain carbon black, comprising the following steps: a) a solid feedstock (100) based on used tyres is sent into a reaction zone (10) in the presence of a liquid solvent (340) comprising aromatic compounds to at least partly dissolve said solid feedstock and to thermally decompose said dissolved solid feedstock so as to obtain carbon black (160) and a first hydrocarbon-based liquid fraction (120); b) a molten plastic feedstock (200) is sent together with at least a portion of the first hydrocarbon-based liquid fraction (120) obtained on conclusion of step a) into a conversion zone (20) to dissolve said molten plastic feedstock (200) and to thermally decompose said dissolved plastic feedstock so as to obtain a second hydrocarbon-based liquid fraction (230).

Abstract: The present invention relates to a process for desulfurizing a cracked naphtha containing organic sulfur compounds comprising the following steps: a) feeding the cracked naphtha to a distillation column comprising a bottom reboiler; b) fractionating said cracked naphtha into a light naphtha fraction and a heavy naphtha fraction which is removed as bottoms from the distillation column; c) feeding the heavy naphtha fraction and hydrogen to a hydrodesulfurization unit containing a hydrodesulfurization catalyst to produce a desulfurized heavy naphtha effluent. The process further comprises a step of providing heat to the distillation column by an intermediate reboiler powered with a heat source having a temperature lower than that one of the bottom reboiler.

Abstract: The present invention describes a liquid-liquid extraction column with perforated plates and downpipes, having a majority of so-called “open” plates and a minority of so-called “closed” plates, the two types of plates differing in the degree of perforation. Application of the said column to the treatment of liquid-liquid systems with time-variable coalescence.
