    Abstract: There is disclosed a method and an apparatus for reducing the amount of waste, requiring special handling and possible destruction, in a process involving vaporization, in an evaporator apparatus (1-6, V1-V6), of a water solution containing environmentally hazardous substances. A considerable amount of the water content of said water solution is vaporized in a reusable vaporization chamber (2a). At a certain time, the vaporization process is stopped, so that the remaining water content is 70% to 5% of the initial water content. Thereafter, in a second step, the remaining water solution in the reusable vaporization chamber (2a) is transferred into a separate waste isolating container (6), where the remaining water is subjected to at least one further water-reducing process. The remaining waste, including the environmentally hazardous substances, is left in the waste container for separate handling and possible destruction.

    Abstract: Disclosed is an improved sublimation method for the purification of organic small molecules. The new method features that barriers are applied in the collection region of sublimation tube so that the gas flow path is modified to pass through or bypass the barriers from the heating region to the vacuum pump. The arrangement of the barriers can effectively separate the main product from the impurities. The main product is enriched in a collection region, while the volatile impurities are enriched in an impurity region. This method has been proved to improve the quality of sublimed materials substantially according to the purity measurements and OLED performance tests.

    Abstract: A low-temperature-slush-fluid producing apparatus capable of achieving an increased weight solidification rate of slush fluid is provided. A low-temperature-slush-fluid producing apparatus includes a slush-fluid producing unit that includes a heat exchanger having a heat-transfer surface and disposed in a liquid-phase low-temperature fluid L stored in a container and scraping means for scraping a solid-phase low-temperature fluid formed on a surface of the heat-transfer surface; and a cryogenic-fluid generating unit for supplying into the interior of the heat-transfer surface a cryogenic fluid having a lower temperature than the liquid-phase low-temperature fluid L stored in the container. The low-temperature-slush-fluid producing apparatus is configured so that the flow rate and temperature of the cryogenic fluid flowing into the interior of the heat-transfer surface and the rotational speed or reciprocating speed of the scraping means can be adjusted based on the particle size of the solid-phase low-temperature fluid scraped by the scraping means.

    Abstract: The present invention relates to a process for recovering subliming substances, which deposit in the form of crystals, from a subliming substance-containing gas by combining a cooling operation for lowering the temperature of collecting tubes for the deposition of crystals below the temperature at which the crystals deposit with a heating operation for heightening the temperature of the collecting tubes above the temperature at which the crystals deposit. A subliming substance is continuously recovered in the form of crystals at a high ratio without suffering the recovered crystals from developing a color.

    Abstract: The liquid cooled trap for effectively and efficiently collecting condensable vapor in a chemical vapor reaction system includes two stages. The first stage includes an entrance area to the trap that is purposely designed to be large in space and a very poor heat exchanger in order to avoid condensation and resulting solid deposits that could clog the entrance port to the trap. The second stage comprises a better heat exchanger to spread the condensation and deposits efficiently over a larger surface area and a longer flow path. The second stage is a very efficient heat exchanger to clean up and remove whatever small amount of the condensable vapor remains after the first stage of the trap. The second stage includes cooling coil tubes and cooling cones or fins to increase the overall efficiency of the trap be increasing the interior surfaces upon which the flowing condensable vapor can condense, while not significantly reducing the flow conductance of the trap.
