摘要： The present invention provides a purification system capable of efficiently purifying a mixture containing a plurality of solvents. A purification system 100 of the present invention is for purifying a mixture 70 containing a first solvent, a second solvent, and an impurity other than the first solvent and the second solvent. The purification system 100 includes a first membrane separation device 10 including a pervaporation membrane 11 and a second membrane separation device 20 including a filtration membrane 21. The pervaporation membrane 11 separates the mixture 70 into a first permeated fluid 80 and a first concentrated fluid 81, the first permeated fluid 80 having a lower concentration of the impurity than that in the mixture 70 and having a higher concentration of the first solvent than that in the mixture 70, the first concentrated fluid 81 having a higher concentration of the impurity than that in the mixture 70 and having a lower concentration of the first solvent than that in the mixture 70. The filtration membrane 21 separates the first concentrated fluid 81 into a second permeated fluid 90 and a second concentrated fluid 91, the second permeated fluid 90 having a lower concentration of the impurity than that in the first concentrated fluid 81, the second concentrated fluid 91 having a higher concentration of the impurity than that in the first concentrated fluid 81.

摘要： The present invention provides a metal organic framework suitable for increasing a flux of a permeation fluid permeating through a separation membrane. The metal organic framework of the present invention includes a metal ion and an organic ligand. The organic ligand includes, besides a functional group to be coordinated with the metal ion, a first functional group and a second functional group different from the first functional group. The second functional group is a hydroxy group, a nitro group, or a carboxyl group. A ratio of the number of moles of the second functional group with respect to a total value of the number of moles of the first functional group and the number of moles of the second functional group is 30 mol% or less.

摘要： Provided is a carbon-dioxide capture and treatment system comprising: a carbon dioxide-enriched mixture gas generation device comprising a separation membrane capable of increasing a carbon dioxide concentration of a mixture gas taken therein, thereby generating a carbon dioxide-enriched mixture gas; a carbon dioxide conversion device configured to convert carbon dioxide in the enriched mixture gas received from the carbon dioxide-enriched mixture gas generation device, into a chemically stable compound; a final treatment device comprising an adsorbent, wherein the final treatment device is configured to adsorb the carbon dioxide by the adsorbent, thereby separating the carbon dioxide from other gas components; and a carbon dioxide direct capture device configured to take in air contained in an ambient environment, and supply the taken-in air to the final treatment device or an upstream side thereof in the carbon-dioxide capture and treatment system. The carbon-dioxide capture and treatment system is operable to treat carbon dioxide generated inside a plant entirely within the plant, without emitting the carbon dioxide to the outside of the plant, and to take in air contained in an ambient environment and subject the intake air to the same treatment as that for emission gas from the plant, so that it is possible to allow carbon dioxide emissions from the plant to the outside to have a negative value.

A separation membrane 10 of the present invention includes a separation functional layer 1, an interlayer 2, and a porous support member 3 in this order in a stacking direction. The interlayer has a thickness of 0.1 µm to 2.5 µm. A total value of the thickness of the interlayer 2 and a thickness of the separation functional layer is less than 4.0 µm. The interlayer 2 contains a polymer compound (E), for example. A distance Ra between a Hansen solubility parameter of the polymer compound (E) and a Hansen solubility parameter of H 2 O is less than 19 MPa 1/2 , for example.
