    摘要: Process for separating one or more compound(s), including at least one n-paraffin, in a hydrocarbon feedstock, in which: A stream, or a portion of a stream of said feedstock, is passed successively and in any order into at least one distillation column and at least one membrane separation unit comprising a selective membrane with regard to at least one n-paraffin; and One or more stream(s) is (are) recovered from the column and the membrane separation unit, each of said streams being enriched respectively with one of said compounds, and at least one of said streams being enriched with at least one n-paraffin. Installation for the implementation of this process. The invention relates in particular to a process and an installation that allow the fractionation of a petroleum fraction that contains hydrocarbon molecules with close boiling points.

    摘要: A process for the production of an isomerate with a RON that is at least equal to 80 and that contains less than 1% by weight of aromatic compounds, starting with a fraction consisting mostly of hydrocarbons with 7 carbon atoms, and containing paraffins, naphthenes, and aromatic compounds in any proportion is described. Said process uses at least one isomerization unit, at least one unit for opening naphthene rings, and at least one separation unit; these units are combined in such a way as to recycle, to exhaustion, methyl cyclohexane, toluene, and normal paraffins and monobranched paraffins.

    摘要: The present invention relates to a method of deacidizing a gaseous effluent comprising at least one of the acid compounds as follows: H2S, mercaptans, CO2, COS, SO2, CS2, wherein the following stages are carried out: a) contacting the acid compounds contained in said effluent with reactive compounds forming a liquid, so as to obtain a gaseous effluent depleted in acid compounds and a first liquid fraction comprising products formed by reaction of the reactive compounds with acid compounds, and reactive compounds that did not react with acid compounds, b) contacting said products contained in the first liquid fraction with extraction compounds forming a second liquid fraction so as to obtain a product-depleted first liquid fraction and a product-enriched second liquid fraction, c) recycling to stage a) the first liquid fraction obtained in stage b), said first liquid fraction obtained making up at least part of said liquid, d) regenerating the second liquid fraction obtained in stage b) so as to release acid compounds in gaseous form and to obtain a mixture of reactive compounds and of extraction compounds.
