Preheated edible, food grade oils and fats are exposed to temperatures between 290° C. and 475° C. under vacuum, in the presence of oxygen. The developing flavor vapors are immediately and completely removed from the heated oils and fats. The mixture of air-purge/flavor-vapor is immediately carried away from the heat transfer surface of the edible oil or fat. An evaporator, preferably a spinning disc, spinning band or thin film evaporator, without a condenser is used as process equipment. The air-purged flavor-vapors are diffused and absorbed in an absorption device into suitable food-grade liquids.

  • Patent number: 8618334
    Abstract: Methods for continuously preparing cyclohexanone from phenol make use of a catalyst having at least one catalytically active metal selected from platinum and palladium. The process includes enriching phenol in a distillation fraction as compared to a subsequent fraction, wherein the subsequent fraction includes phenol and side-products having a higher boiling point than phenol. Distillation is carried out in a vacuum distillation column equipped with trays in the lower part of the column. In an upper part of the column, i.e., in the part above the feed inlet, packing material is present instead of trays in at least part thereof. The packing material has a comparable or improved separating efficiency, and provides a reduction of the pressure drop by at least 30%, preferably more than 50%, as compared to the case with trays in the upper part, under otherwise similar distillation conditions.

  • Patent number: 8617359
    Abstract: A method for distilling a starting material that includes a liquid Fd to be distilled, uses a gas-tight container system that is resistant to excess and/or negative pressure. The container system includes a condenser for condensing the liquid Fd, which has turned to vapor and whose temperature can be adjusted, to give the condensation product, and a vapor chamber connecting the evaporator and the condenser. The pressure and temperature in the vapor chamber are monitored and controlled so that distillation is always carried out in a range close to the saturation vapor pressure of the liquid Fd to be distilled. If the pressure is too high, it is reduced so that especially foreign gas is removed. An installation includes a container for distillation according to method.

  • Patent number: 8361277
    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 vapor, which in use condenses and releases latent heat of vaporization to the liquid sample in the container. As the temperature of the sample is dependent on the saturated vapor temperature of the liquid in the reservoir, the temperature of the samples is reliably limited, thereby avoiding overheating.

    Abstract: A vacuum dehydrator for processing an oil containing entrained contaminants such as water, air, and particulates comprises a tower enclosing upper and lower chambers. A random packing is contained in the upper chamber. The oil is preheated to a temperature above the boiling point of water and is introduced into the upper chamber for downward flow through the random packing into the lower chamber. Entrained air and water is retained as water vapor in the upper chamber, and particulates are retained in the random packing. Heated ambient air is introduced into the lower chamber for upward flow through the random packing into the upper chamber, and the upper chamber is cooled to condense the water vapor. Oil and condensed water are pumped respectively from the lower and upper chambers.

  • Patent number: 8337672
    Abstract: The invention relates to the oil processing industry and can be used for producing vacuum in a vacuum petroleum distillation column. The inventive method involves pumping out a vapor-gas medium from the column by of a gas-gas ejector in such a way that a vapor-gas mixture is formed at the entry thereof and supplying said mixture to a condenser for producing a gas mixture and a vapor phase condensate. The gas mixture is supplied from the condenser to a liquid-gas jet apparatus and the condensate is delivered to an additional separator. A hydrocarbon-containing condensate is removed from the additional separator for the intended use thereof and a water-containing condensate is fed to a steam generator for producing steam by supplying heat of a hot distillate evacuated from the vacuum column. The thus obtained steam is used in the gas-gas ejector as a high-pressure gas.
