摘要： The invention relates to a fluid distributor (9,10)for a column (1)comprising at least one cell (2) containing a bed of particles (3), the fluid distributor (9, 10) comprising: - a floor (11, 21) comprising at least one injection point (15, 25) providing a fluidic connection on either side thereof; - a layer of resistive medium (12, 22) fixed on one face of the floor(11, 21), the resistive medium being permeable to the fluid; - a spacing device (13, 23) inserted between the floor (11, 21) and the layer of reistive medium (12, 22) and maintaining a space for the circulation of the fluid between the floor (11, 21) and the layer of resistive medium (12, 22). The invention also relates to a column, in particular a chromatography column, provided with this fluid distributor.

摘要： The invention related to a method for purifying a first fatty acid, preferably polyunsaturated, using an initial mixture further comprising at least one second fatty acid, optionally a third fatty acid and optionally a fourth fatty acid, with the method comprising: a first step of chromatographic separation in liquid phase, using the initial mixture, carried out in a first unit for chromatographic separation, making it possible to recover on the one hand a first flow enriched with a first fatty acid and on the other hand a flow enriched with a second fatty acid, optionally, a second step of chromatographic separation in liquid phase, using the first flow enriched with a first fatty acid, carried out in a second chromatographic separation unit, making it possible to recover on the one hand a second flow enriched with a first fatty acid and on the other hand a flow enriched with a third fatty acid; optionally, a third step of chromatographic separation in liquid phase, using the third flow enriched with a first fatty acid, carried out in a third chromatographic separation unit, making it possible to recover on the one hand a third flow enriched with a first fatty acid and on the other hand a flow enriched with a fourth fatty acid; at least one among the first unit for chromatographic separation, the second unit for chromatographic separation and the third unit for chromatographic separation being a static bed chromatographic separation unit with a single column with recycling in stationary state.

摘要： A method for purifying an amino acid from an initial mixture is disclosed, in which the amino acid includes an aromatic ring and has an acidity constant Ka, the method including: a first step of putting the initial mixture into contact with a strong cation resin, at a pH greater than or equal to pKa; and a second elution step with an aqueous solution of eluent having a pH greater than the pH of the first step, giving the possibility of collecting a flow enriched in the amino acid.

摘要： The invention concerns a purification method comprising: providing a flow comprising a glycol, monovalent ions and multivalent ions; treating this flow with ion exclusion chromatography comprising: injecting the flow into a chromatographic unit comprising an ion exchange stationary phase; injecting an eluent into the chromatographic unit; collecting a fraction at the outlet of the chromatographic unit; the collected fraction being enriched with glycol and depleted of monovalent ions and multivalent ions relative to the flow.
The invention also concerns an installation adapted to implement this method, and its application to the regeneration of an anti-hydrate agent.-

摘要： The invention relates to a method for chromatographic separation, comprising at least one step of elution of species held on a stationary phase by means of an eluent, followed by a step of moving the eluent in contact with the stationary phase by means of a compressed gas. Preferably, the movement step takes place after a step of elution of the product(s) of interest and/or after a step of regeneration of the stationary phase.

摘要： The invention relates to a method for treating sugar comprising: placing a coloured sugar juice in contact with an ion exchange resin so as to charge the resin with colouring agents and to collect a bleached sugar juice; regenerating the colouring-charged resin, comprising: placing the charged resin in contact with a regeneration brine comprising a chloride salt; and collecting a regeneration effluent, the regeneration effluent comprising at least three fractions A, B and C, fraction A having a higher concentration of chloride salt than fractions B and C; and recycling the regeneration effluent, comprising: nanofiltration of fraction A of the regeneration effluent in order to obtain a first permeate and a first retentate; diafiltration of the first retentate, said diafiltration comprising: dilution of the first retentate with the fraction B of the regeneration effluent; nanofiltration of the mixture in order to obtain a second permeate and a second retentate; mixing of the first permeate with the second permeate and fraction C of the regeneration effluent,
