摘要： A process for preparing high-purity phytantriol, that includes rectifying the phytantriol which is obtained and is contaminated with lower and/or higher boiling byproducts under medium vacuum in rectification columns containing metal cloth packings with ordered structure using channel liquid distributors with a minimum of 500 drip points/m2, which are arranged at an angle of 90° to the cloth layers of the packing elements located directly below the distributors, in which 2 or more of the packing elements underneath the liquid distributors have only a small height, which ensure absolute exclusion of air and a strictly adiabatic procedure. The preparation of high-purity phytantriol takes place particularly advantageously when the phytantriol which is contaminated with byproducts is a phytantriol which has been obtained by reacting isophytol with performic acid and subsequently hydrolyzing the product formed in the reaction with alkaline agents in a manner known per se.

摘要： A large and economical type of multi-stack vertical tube evaporator (MS-VTE) is disclosed having units of multiple stacks of vertical tube bundles or stages mounted in a single vessel, and having its liquid feed pumped to the uppermost VTE bundle stack or stage and having the feed then cascading downward through the lower bundle stacks in series flow, and wherein all the tube bundles are heated with the same waste steam of no or low $-value, e.g. with turbine reject steam in parallel flow under vacuum into the steam-sides of all tube bundles in the unit through a common steam conduit; and wherein the feed liquid is progressively evaporated from stage to stage or stack to stack and the vapors produced in the tubes of each bundle during the partial evaporation of the feed are separated between the stacks and condensed by parallel flow into one or more condensers. Applied to seawater desalination in a co-generation procedure with a coastal power plant, this evaporator produces about one pound of distilled water per pound of turbine reject steam used under vacuum and applied to single-effect mode in one evaporator unit or several units mounted in a single vessel with a condenser, to substantially reduce the cost of such useful distilled water. When applied in a similar cogeneration procedure but in a multi-effect series mode of several such units, or multiple units, the rate of distilled water production can be increased several-fold based on the amount of turbine reject steam applied.

摘要： There is provided a reduced-pressure distillation system, which is relatively simple in construction, easy in operation without depending only on driving of a vacuum pump, and therefore can be manufactured and operated at low costs. The system includes an impure water tank, a separating tank, a drainage tank, and a collecting tank. The impure water tank, the drainage tank, and the collecting tank each has an outside pressure communicating chamber, which makes contact with outside pressure, and a cell, which communicates with the outside pressure communicating chamber corresponding thereto and is sealed with respect to the outside pressure during operation of the system. The separating tank is sealed with respect to outside pressure and has an evaporator provided therein. Impure water is fed from the cell of the impure water tank to the evaporator, by using an effective head between levels of the impure water in the impure water tank and priming supplied to the drainage tank. Remaining water in the evaporator is discharged to the cell of the drainage tank. Purified water in a bottom portion of the separating tank, which is obtained by evaporating the impure water by activation of the evaporator, is collected into the cell of the collecting tank. The cells of the respective tanks communicate with each other via the separating tank. Evacuation within the separating tank is carried out to keep each cell in a pressure-reduced state.

摘要： The invention essentially relates to a method for vacuum distillation of liquids that includes feeding a polar liquid into a vacuum-producing liquid-gas jet apparatus as a motive liquid if evacuation of a nonpolar gas-vapor medium is to be effected. Further, the method includes condensing the nonpolar gas-vapor medium, forming a gas-liquid mixture, disengaging a gaseous phase from the mixture, forming a liquid emulsion containing the polar liquid and a nonpolar condensate, separating the emulsion into continuous layers, withdrawing the nonpolar condensate and recycling the polar liquid by pumping it back into the liquid-gas jet apparatus. A nonpolar liquid is to be used as the motive liquid of the liquid-gas jet apparatus if evacuation of a polar gas-vapor medium is required. There is another variant of the method applicable when an evacuated gas-vapor medium contains both polar and nonpolar components. As distinct from the previous variants, in this case, the method comprises forming a liquid emulsion containing a polar liquid, a polar condensate and a nonpolar condensate, mixing of the polar substances and forming a polar liquid medium, separation of the emulsion into layers of the polar medium and nonpolar condensate, withdrawing a surplus amount of the polar medium, and recycling a remainder of the polar medium as the motive liquid. The system realizing the methods has an evacuated reservoir with a pipeline for evacuation of a gas-vapor medium, a vacuum-producing device composed of a liquid-gas jet ejector, a separator and a pump. A suction port of the pump is connected to a section of the separator, where a layer of a liquid being used as the motive liquid settles.

摘要： A method of remediating water contaminated by dissolved gases and liquids and suspended particles wherein the contaminated water is collected into a closed container without filling the container and heated to a temperature below the boiling point of water. Negative pressure is then drawn on the closed container without causing the water in the container to boil, whereby the dissolved gases and liquids in the contaminated water, having a boiling point lower than water, will evaporate out of the water into the head space above the water in the container. Finally, atmospheric air and/or oxygen are allowed into the container to push the vapors out of the head space of the container.

The invention also relates to a system for realizing this method, which has a rectification column, a liquid-gas ejector, a pump, a heat exchanger and further is furnished with a separator. An outlet of the ejector and the suction side of the pump are connected to the separator, and the pump is connected to the nozzle inlet of the ejector through the heat-exchanger.
