Abstract: A process for the isomerization of a feed of hydrocarbon compounds containing C5 and/or C hydrocarbon compounds, comprising: a) supplying an isomerization unit with at least one liquid fraction of the feed of hydrocarbon compounds and isomerizing the feed in the presence of a chlorinated catalyst; b) supplying a stabilization unit containing at least one stabilization column with the effluent obtained from the isomerization unit and separating the effluent; c) providing an absorption unit having one absorption column; d) extracting a liquid flow enriched in chlorinated compounds from the absorption unit which is recycled to the isomerization unit; and e) extracting the liquid flow containing at least one isomerate from the stabilization unit.

Abstract: The present invention relates to a process for producing high-purity para-xylene, comprising a single step of separation by adsorption in an SMB, with a subsequent step of separation by distillation in a first three-fraction distillation column producing at least two raffinates and optionally of two isomerization steps, making it possible to improve the overall para-xylene yield of the aromatic loop and to minimize the economic impact.

Abstract: A process for recovering 1-hexene comprising: a) separating the mixture obtained from the ethylene trimerization reaction into a top fraction comprising ethylene and a bottom fraction, b) separating a portion of the bottom fraction obtained from step a) into a top fraction comprising 1-hexene and 1-butene and a bottom fraction, c) separating a portion of the fraction comprising 1-hexene and 1-butene obtained from step b) into a top fraction principally comprising 1-butene and into a bottom fraction principally comprising 1-hexene, and in said process: a portion of the bottom fraction obtained from step b) is returned to the reaction section and another portion of said bottom fraction obtained from step b) is used in a recirculation loop connecting the reaction section and the column of said step b), said recirculation loop being used to cool the reaction section and to reboil said column of step b).
