    摘要： A liquid-liquid extraction system (1) adapted for the flow of two or more liquids therein is disclosed. The system comprises a mixer settler sub-system (100) and a counter-current liquid-liquid extraction column (200). The sub-system (100) comprises one or more mixer settlers (110) connected in series, and the column (200) comprises either a mixing section (260) comprising an agitation means (261) and/or a static section (280) comprising an internal (281). The first outlet (131) of the mixer settler sub-system (100) is in fluid communication with the first inlet (221) of the column (200) and the second inlet (112) of the mixer settler sub-system (100) is in fluid communication with the second inlet (222) of the counter-current liquid-liquid extraction column (200). The invention further relates to a counter-current liquid-liquid extraction process for using said system 1. The present invention further relates also to the use of the system (5) or process in removing aromatic compounds from organic streams, in treating an oil stream of a refinery, or in a liquid-liquid extraction process having at least two feed streams of different viscosity, similar density, or low interfacial tension.

    摘要： A method for separating an alkyl aromatic hydrocarbon, the method having a step of adding a first diluent and an extractant having a superacid to a mixture comprising the alkyl aromatic hydrocarbon and one or more isomers thereof to carry out an acid-base extraction to thereby form a complex of the alkyl aromatic hydrocarbon with the superacid, and thereafter separating the complex from the mixture, and a step of adding an eliminating agent having a relative basicity in a range of 0.06 to 10 with respect to the alkyl aromatic hydrocarbon and a second diluent to the complex, and carrying out complex exchange of the alkyl aromatic hydrocarbon for the eliminating agent to thereby separate the alkyl aromatic hydrocarbon from the complex.

    摘要： The invention relates to a liquid-liquid extraction process, comprising: the provision of a main input liquid stream, comprising at least one compound of interest and an excess compound; the provision of a liquid scrubbing stream; the extraction of the excess compound from the main input liquid stream by contact with the liquid scrubbing stream, making it possible to collect a main output liquid stream, depleted in excess compound with respect to the main input liquid stream; in which: the main input liquid stream and the liquid scrubbing stream exhibit a difference in density of less than or equal to 50 kg/m3 and also an interfacial tension of less than or equal to 3 dyn/cm; and the extraction stage is carried out in a packed contactor with a ratio by weight as input liquid scrubbing stream/main liquid stream ranging from 0.3 to 0.5. The invention also relates to a process for the production of acrylic ester in which the production stream is treated by means of the above liquid-liquid extraction process.

    摘要： The invention relates to a process for obtaining at least one aromatic amine from a liquid mixture comprising water and the at least one aromatic amine by extracting with at least one nitroaromatic in an extraction column (1) to form an essentially water- comprising raffinate stream and an extract stream comprising the at least one nitroaromatic and the aromatic amine. The extraction column (1) is divided by a dividing wall (3) into two regions (5, 7), and, in the case of an amount of liquid for separation which is less than a minimum cross sectional loading of the entire extraction column (1), the liquid mixture to be separated is fed only to one of the regions (5, 7) of the extraction column (1) divided by the dividing wall (3). The invention further relates to a process for preparing an aromatic amine and to an apparatus for separating a liquid mixture comprising water and at least one aromatic amine by extracting with at least one nitroaromatic, comprising an extraction column (1).
