    摘要: PURPOSE: A separation and recovery method separating hydrogen fluoride from fluorine-containing compound is provided to substantially separate and recover hydrogen fluoride harmful to a human body and the environment due to a high separation and recovery rate of hydrogen fluoride, thereby securing the safety of a future landfill and preventing destruction of the environment. CONSTITUTION: A separation and recovery method separating hydrogen fluoride from a fluorine-containing compound comprises the following steps. A by-product which is generated after disintegrating a fluorine-containing compound into supercritical water is contacted with an absorber, and only hydrogen fluoride is firstly separated and recovered from the by-product. The remainder hydrogen fluoride which is not separated and recovered at the previous step is secondly separated and recovered. The absorber is at least one selected from the group composed of active alumina and silica gel. An absorption liquid is at least one selected from the group composed of water and boric acid. The fluoride-containing compound is either chlorofluoro carbon or hydrochlorofluorocarbon. [Reference numerals] (AA) Removal efficiency(%); (BB) Adsorption time;

    摘要: A process, composition and apparatus for the removal of impurities from corrosive gases, particularly halogen-containing gases, down to about 100 ppb concentration are described. The critical component is zirconia (ZrO2), which in a variety of physical forms is capable of dehydrating such gases. The zirconia can be in the form of a coating on a substrate, as a granular bulk material, or deposited within the pores of a porous body. The zirconia is retained in a simple container which is easily installed in a gas supply line, such as to a gas-or vapor- deposition manufacturing unit. The purification process can be operated for long periods of time in the presence of these gases. The invention provides final purification to gas streams intended for gas-or vapor- deposition formation of high purity electronic, prosthetic or similar products, and can be used in combination with a preliminary dehydration process or a solid particulate removal unit upstream.
