    摘要: A process for eliminating at least pollutants including polar compounds present in a first fluid, with said first fluid sent to a subsequent treatment, e.g., an etherification process: a) the first fluid containing pollutants is contacted with an auxiliary fluid such as a vapor phase, under operating conditions that are selected so as to obtain, at the end of this first stage, said first fluid that is purified and freed of, for the most part, pollutants, and a vapor phase that is loaded with pollutants, said vapor phase being produced during one phase of the process, and b) at least a portion of said first purified fluid is recycled to a subsequent treatment stage.

    摘要: An enhanced ether production process from an olefinic cut containing at least one iso-olefin and from an alcohol comprises a stage of removal of the acetonitrile present in the hydrocarbon feed by liquid-liquid extraction, the extraction solvent being a non-aqueous ionic liquid of general formula Q+A−, wherein Q+ is an ammonium, phosphonium and/or sulfonium cation, and A− an anion likely to form a liquid salt with said cation. Advantageously, the method according to the invention generally allows the amount of water at the etherification reactor inlet to be divided by at least two and thus the purity of the ether produced to be improved.

    摘要: A process for carrying out a reaction on an organic feed, for example dimerization, co-dimerization, oligomerization or metathesis of olefins, as described in which the catalyst is a catalytic metal compound dissolved in a non-aqueous ionic medium which is not or is only slightly miscible with hydrocarbons. The reaction is carried out in a system comprising at least two treatment loops each comprising at least one reaction zone and at least one zone for separating the organic and polar phases between which the polar medium containing the catalytic metal compound, and the organic phase circulate. Fresh polar phase is injected into the second loop and used polar phase is eliminated from the first loop. The hydrocarbon to be transformed is injected into the first loop and the products are withdrawn from the second loop. The invention also concerns a unit for carrying out the process.

    摘要: Synthetic oil that contains wholly or partly of dialkylbenzenes and/or partially or totally hydrogenated dialkylbenzenes. The synthetic oil according to the invention can also be used as an oil base or oil base additive and comprises at least one dialkylbenzene and/or at least one partially or totally hydrogenated dialkylbenzene and meets the general chemical formula: R1—A—R2 in which R1 and R2 represent alkyl groups and A is a benzene core and/or a cyclohexane core and/or a cyclohexene core and/or a cyclohexadiene core and is characterized in that it contains between 1 and 20% by weight or ortho isomers and in that at least one of the alkyl groups is attached for the most part to group A by carbon 2 of the aliphatic chain. The two alkyl groups are preferably attached for the most part to group A by carbon 2 of the aliphatic chain.
