Abstract
1. Способ выделения с одновременным концентрированием органических веществ с помощью первапорационного разделения жидких смесей, включающий создание градиента парциального давления через мембрану, селективную по целевому компоненту, отличающийся тем, что первапорационное разделение проводят через две селективные по целевому компоненту мембраны, между которыми существует зазор, а процесс массопереноса паров компонентов жидкостей через мембраны проводят так, чтобы скорость массопереноса через вторую мембрану была выше, чем скорость конденсации пермеата на этой мембране. ! 2. Способ по п.1, отличающийся тем, что градиент парциального давления паров компонентов жидкостей создают подбором одного или нескольких параметров, выбраных из ряда: состав и структура мембраны, их толщина, межмембранные расстояния, концентрация компонентов, температуры. ! 3. Способ по п.1, отличающийся тем, что питающий раствор, из которого осуществляют выделение целевого компонента, имеет концентрацию целевого компонента в обогащаемом растворе, равной или превышающей концентрацию целевого компонента в питающем растворе. ! 4. Устройство для выделения и одновременного концентрирования органических веществ с помощью первапорационного разделения жидких смесей для осуществления способа по п.1, содержащее два контура для циркуляции растворов, содержащих целевой компонент, отделенных друг от друга селективной по целевому компоненту мембраной, отличающееся тем, что оно дополнительно содержит вторую мембрану, расположенную относительно первой с зазором, выполненным с возможностью обеспечения массопереноса между ними. 1. The method of separation with the simultaneous concentration of organic substances using pervaporation separation of liquid mixtures, including the creation of a partial pressure gradient through a membrane selective for the target component, characterized in that the pervaporation separation is carried out through two target-selective membranes between which there is a gap, and the mass transfer process of vapors of liquid components through the membranes is carried out so that the mass transfer rate through the second membrane is higher than the speed condensation of permeate on this membrane. ! 2. The method according to claim 1, characterized in that the partial pressure gradient of the vapor of the components of the liquids is created by selecting one or more parameters selected from the range: composition and structure of the membrane, their thickness, intermembrane distance, concentration of components, temperature. ! 3. The method according to claim 1, characterized in that the feed solution from which the target component is isolated has a concentration of the target component in the enrichment solution equal to or higher than the concentration of the target component in the feed solution. ! 4. A device for the separation and simultaneous concentration of organic substances using pervaporation separation of liquid mixtures for implementing the method according to claim 1, containing two circuits for circulating solutions containing the target component, separated from each other by a membrane selective for the target component, characterized in that it additionally contains a second membrane located relative to the first with a gap made with the possibility of mass transfer between them.
