摘要： The present application relates to a method for removing an unreacted vinyl chloride monomer (VCM) in polyvinyl chloride (PVC). According to an illustrative stripping apparatus and a stripping method using the stripping apparatus of the present application, in a stripping process using steam, a temperature difference between a raw material including a target substance to be removed and steam is minimized to suppress foam generation in the stripping process, thereby increasing efficiency of removing the target substance to be removed, particularly, an unreacted VCM in PVC. In addition, a cleansing cycle to remove foams generated in the stripping apparatus can be reduced, thereby not only securing economic feasibility of the process, but also preventing degradation in quality of a final product that may occur when an antifoamer to remove the foams is used.

摘要： Provided is a water distillation system (10) for distilling sea or brackish water. The system has a feed water arrangement (14 and 37) for supplying feed water from a feed water source (FEED) to one or more flashing stages (28). Each flashing stage has a water flash evaporator (29) for vaporising at least a part of the feed water therein, and a condenser (35) for receiving the vapour and to convert at least a part of the vapour into distilled water. A heat storage arrangement (20) provided with a heat generating source for storing heat energy is used to heat a fluid medium flowing through it. A heat exchange arrangement (24) receives the hot fluid medium and transfer heat to a stream of vapour flowing under pressure from each flashing stage. The vapour leaving the heat exchange arrangement being at a raised temperature is arranged to be condensed into water at the condenser and to transfer some of its latent heat to the evaporator.

摘要： The plant for tomato juice concentration uses a falling-film evaporator (1) of known type, with an external sleeve (2) which surrounds a vertical bundle of tubes (3) divided into a plurality of sectors (3a, 3b, 3c and 3d), in which the tomato juice circulates in succession, and which is combined with a heat exchanger (7) of known type, which is arranged externally of the evaporator (1) and which is divided into a plurality of sectors (7a, 7b and 7c) in each of which the tomato juice is circulated and heated as it exits from a sector of tubes (3a, 3b, 3c) of the evaporator before being introduced into a successive sector. The plant also comprises a compressor (8) of known type which aspirates steam from a bottom zone, being a separation chamber (5a) of the evaporator (1), compresses it and reintroduces it into the central part (l a) of the evaporator. The compressor is powered by a gas turbine (9) of known type and in turn powered by live steam coming from a boiler (10). Steam discharging from the gas turbine (9) constitutes the heating fluid necessary for operating the plant.

摘要： The invention relates to a method and a device for purifying waste water that is polluted with organic and/or inorganic matter. The invention is characterized in that the waste water is evaporated and condensed within a primary system (13) and a secondary medium (14), preferably untreated water, within a self-contained secondary system (14) that contains a compressor (66) and that is separate from the primary system (13) by evaporating the waste water by heating it on the secondary medium (14) previously compressed in the compressor (66) and further heated up. The steam is guided through a cyclone (58) and the secondary medium expanded in the secondary system (14) is evaporated by condensing the waste water steam. The total waste water fed to the primary system (13) is subdivided into a first partial flow (23) and an at least commensurate second partial flow (24). The first partial flow (23) is brought to a temperature close to the boiling point in a first heat exchanger (28) at the outlet of the primary system through which hot distilled water (31) flows and the second partial flow is brought to a temperature close to the boiling point in a second heat exchanger (38) through which the removed hot clarification (36) flows. The ratio referred to as concentration factor (CF) of supplied total water per time unit to clarification quantity per time unit is selected to range between greater 1 and approximately 20. The inventive method is suited for the thermal reprocessing of waste water and produces germ-free distilled water of high quality and a greater or lesser concentration of the water to be evaporated while saving energy.

摘要： There is described a method for the treatment and processing of solutions of an organic fluid, water and one or more compounds of alkaline earth metals, alkali metals and metal ions, comprising the following steps: a) conducting a stream (5) consisting of organic fluid, water and one or more compounds of alkaline earth metals, alkali metals and metals ions to a salt reduction and crystallization unit (6), b) evaporating and optionally partially condensing the stream (5) and providing thereby a steam (9, 10) of evaporated water and organic solvent and a steam (8) of organic fluid and the compounds of alkaline earth metals, alkali metals and/or metal ions, c) conducting the steam (8) consisting substantially of organic fluid and the compounds of alkaline earth metals, alkali metals and/or metals ions to a salt reduction means (24), d) nucleating crystals of the compounds of alkaline earth metals, alkali metals and/or metal ions by means of depressurization and temperature increase, e) removing the portion of the precipitated crystals and/or particles from the organic fluid. The method is particularly well suited for processing of solution consisting of mono-, di, tri, or polyethyleneglycol or mixtures thereof. There is also described a means for carrying out the method.

摘要： Process water from pulp manufacture (2) is purified in a separator device (7) by mechanical or a combination of mechanical and chemical methods and is thereafter evaporated (3), at least part of the concentrate resulting from the evaporation being recycled (4) and mixed with the process water fed into the separator device (7). In a preferred embodiment, a precipitant (5) is added to the mixed water comprising the process water and the concentrate. The part of the concentrate not recycled and mixed with the process water (11) is supplied, optionally after further evaporation, with an acid (13) to a pH of 1-5, whereupon resulting flocs and precipitates are removed in a separator device (12).
