Abstract:
A fully automatic vaporizing separator for liquid media which is capable of coping with size increase. The vaporizing separator, which is for separating a liquid medium and a liquid mixture, comprises: a vaporizing means in which either of a liquid medium and a liquid mixture comprising the liquid medium and a nonvolatile substance is stored to thereby form a liquid surface and which vaporizes the liquid medium to give a vaporized medium; a separation means which cools a gas discharged from the vaporizing means and the vaporized medium to condense the vaporized medium and thereby convert it into a condensed medium and which thus separates the condensed medium from the gas. The vaporizing separator for a liquid medium and the liquid mixture includes: a pressure-measuring means which measures the pressure of the gas; a pressure-difference determination means which determines the difference between the pressure in a given position in the vaporizing means and the pressure of the gas; and a calculation means which calculates the position of the surface of the liquid relative to that given position from the pressure of the gas and the pressure difference.

Abstract:
The invention relates to a device for recovering solvents from a hydrocarbon mixture contaminated with impurities, comprising a container (12) with a jacket (12'), to which is assigned a heating device (18) for evaporating the solvent, a head (12'') covering the jacket (12') to which is assigned a cooling device (20) for condensing the evaporated solvent, and an inlet (22) for introducing the contaminated hydrocarbon mixture into the container (12). The head (12'') of the container (12) on its inner side has a surface (28) for condensing the solvent which runs upwards and is substantially shaped like a cone or has a similar shape, and, adjoining and situated below said surface (28), a collecting channel (30) for drawing off the condensed solvent. The invention also relates to a corresponding method.
Abstract:
A distilling device having a vapor compression distiller. The vapor compression distiller can include a reservoir for receiving liquid for distillation. Evaporation surfaces can receive the liquid and evaporate the liquid into evaporated vapor for subsequent condensing. Condensing surfaces can receive the vapor and condense the vapor into distillate. A compressor can deliver the vapor to the condensing surfaces. The distilling device can also include an engine that produces heat. A boiler can be heated by the heat from the engine for producing a working vapor. A vapor turbine can be driven by the working vapor. The vapor turbine can be mechanically coupled to the compressor for mechanically driving the compressor, thereby reducing electrical power needs of the vapor compression distiller.

Abstract:
An evaporator is provided for evaporation of liquid from a solution or liquid mixtures, together with methods of operation of the evaporator. The evaporator comprises a chamber (1); a liquid reservoir (3) for holding a heat transfer liquid exposed to the interior of the chamber; a support (6) for supporting a container (8) in the chamber, such that the liquid sample in the container is exposed to a fluid path (15) for connection to a condenser (16), the fluid path being separated from the chamber interior, and at least a portion of the container is closely thermally coupled to the chamber interior; and means (4) for heating the heat transfer liquid in the reservoir to create heat transfer liquid vapour, which in use condenses and releases latent heat of vaporisation to the liquid sample in the container. As the temperature of the sample is dependent on the saturated vapour temperature of the liquid in the reservoir, the temperature of the samples is reliably limited, thereby avoiding overheating. High levels of heat energy may be delivered controllably to the samples, enabling a high evaporation rate to be achieved at relatively low temperature.
Abstract:
A liquid being processed, such as nonaqueous solvents and the like which contain dirty components, is heated and evaporated under reduced pressure in a distillation still (1) having a heating mechanism (4) which uses a heat-resisting oil as a heating medium. Vapor of the nonaqueous solvents is condensed and liquefied in a condenser (19). A condensed and liquefied distillate is circulated through a moisture separator (31). The interior of the distillation still (1) is reduced in pressure by an ejector (34) provided in a distillate circulating system to be in a predetermined condition of reduced pressure. Residue remaining in the distillation still (1) is discharged into a liquid storage tank (22), which is connected to the distillation still (1) via a waste fluid pipe (21) provided with an opening and closing valve (53) and is connected via a conducting pipe (54) to have the pressure of the tank reduced to a similar level to that of the distillation still (1), and is cooled in a cooler (48). In this manner, a liquid being processed, such as nonaqueous solvents and the like which contain various dirty components, can be efficiently recycled.
Abstract:
Oil-solvent solutions are separated by azeotropic distillation. Despite the reduction in the proportion of solvent in the oil thereby attained, the latter is regarded as special waste. The new process provides virtually solvent-free oil. In it the oil-solvent solution is agitated with dry gas. The solvent-enriched gas is removed and dried by abrupt cooling. The solvent which condenses out and the dried gas are removed and the solvent-free oil left behind.
