摘要： The invention uses both heating and cooling zones to prevent the precipitation of solids onto equipment surfaces until they are efficiently removed from the gas phase via one or more heat exchangers. Each heat exchanger may be regenerated to melt off the solids when the amount collected becomes excessive. A storage plenum is available under each heat exchanger to store the melted solids until final removal to avoid the need to open the equipment for the removal of the unwanted solids.

摘要： A multicomponent, ground based system for reducing the hazard of explosion of aircraft fuel in the on board tanks of aircraft. The system is adapted to provide a supply of scrubbed fuel having a low concentration of dissolved oxygen. The scrubbed fuel can be supplied from bulk storage tanks to dispensing stations nearby the aircraft loading and boarding positions at an airport. The system also includes equipment adapted to wash the ullage of the aircraft fuel tanks to remove excess oxygen above the fuel in the tanks. The system further includes a gas cleaning unit to strip excessive amounts of volatile organic compounds from gas exhausted during operation of the system thereby producing environmentally benign atmospheric emissions. The system also includes redundant sources of inert gas so that the system can continue to operate in the contingency that one of the inert gas sources temporarily ceases to operate.

摘要： The cleaning process according to the present invention includes three main steps including supercritical extraction of soluble contaminants with a solvent composition, subcritical removal of particulate material with agitation, and solvent recovery and recycle. The supercritical extraction of soluble contaminants is performed by pumping a solvent composition into a cleaning vessel containing articles to be cleaned and pressurizing and heating the fluid in the vessel to a supercritical state. Then the subcritical phase is begun to remove particulate material from the articles by reducing the pressure and temperature of the solvent composition in the cleaning vessel to a subcritical state and reforming the liquid/gas interface. Agitation of the articles in the cleaning vessel is provided by recirculation of the solvent composition or by motion of a mechanical device within the cleaning vessel. Due to a density difference between gas and liquid in the subcritical phase, the degree of agitation and resultant particulate removal is maximized. The solvent composition recovery step preferably includes further depressurization of the fluid to separate and remove soluble and insoluble contaminants from the fluid, allowing this solvent composition to be reused. The system may be operated with any gas with suitable solvent properties such as carbon dioxide, carbon dioxide based mixtures, or other known solvents.
摘要翻译： 根据本发明的清洁方法包括三个主要步骤，包括用溶剂组合物超临界萃取可溶性污染物，在搅拌下亚临界除去颗粒物质，以及溶剂回收和再循环。 可溶性污染物的超临界萃取通过将溶剂组合物泵送到含有待清洁物品的清洁容器中并进行加压并将容器中的流体加热至超临界状态来进行。 然后通过将清洁容器中的溶剂组合物的压力和温度降低至亚临界状态并重整液体/气体界面，开始亚临界相从制品中除去颗粒物质。 通过溶剂组合物的再循环或通过清洁容器内的机械装置的运动来提供清洁容器中的物品的搅动。 由于亚临界相中的气体和液体之间的密度差异，搅拌程度和最终的微粒去除率最大化。 溶剂组合物回收步骤优选包括进一步减压流体以从流体中分离并除去可溶性和不溶性污染物，允许该溶剂组合物被再次使用。 该系统可以用具有合适溶剂性质的任何气体操作，例如二氧化碳，二氧化碳基混合物或其它已知溶剂。

摘要： The present invention relates to a continuous processing apparatus and method for cleaning articles with a liquified compressed gaseous solvent mixture. The continuous processing apparatus includes three processing chambers including an entrance chamber, a cleaning chamber, and an exit chamber. The chambers are provided with hatches which are opened and closed at appropriate times to allow the articles to be cleaned to pass into and out of the chambers. The entrance chamber is used for evacuation of the incoming articles to remove the majority of the air and moisture from the articles. After evacuation of the incoming articles, the entrance chamber is pressurized and the articles pass into the cleaning chamber. The cleaning chamber is maintained at a temperature and a pressure at which the liquified compressed gaseous solvent mixture is in a subcritical state and a liquid/gas interface exists between a liquid and a gas portion of the liquified compressed gaseous solvent mixture. The cleaned articles are then passed into a pressurized exit chamber where the liquified compressed gaseous solvent mixture remaining in the articles is evacuated before the cleaned articles are removed from the apparatus.

摘要： A method for the substantial separation of at least one gas component from a gas mixture to generate a residue gas substantially depleted of the gas components to be separated. A semipermeable membrane is provided which has a feed gas side and a sweep gas side. The feed gas side is contacted with a feed gas mixture containing at least one gas to be retained and at least one gas to be separated therefrom. The sweep side is simultaneously contacted with a sweep gas having a pressure lower than that of the feed gas. The partial pressure of certain gas components present on both sides of the membrane are balanced to cause the remaining gas components to diffuse in either direction across the membrane depending upon their differential partial pressures. Apparatus for the gas separation is also provided.

摘要： An apparatus for producing a sterile cryogenic liquid (for example into a container of food) is provided, as well as a method of use of same using a just-in-time approach to production. The apparatus includes at least one cryogenic liquid filter, the filter including filter media having the capability to effectively sterilize cryogenic liquids, the filter media positioned within a housing to accept non-sterile cryogenic liquid and produce sterile cryogenic liquid. The apparatus further includes at least one sterile cryogenic liquid receptor tube, the sterile cryogenic liquid receptor tube having a sterile cryogenic liquid outlet for outflowing sterile cryogenic liquid. The receptor tube is surrounded by a manifold which collects and drains spent condensed steam after a periodic filter sterilization cycle. The receptor tube also collects raw cryogenic fluid, which helps insulate sterile cryogen in the receptor tube. The cryogenic liquid filter is provided within a vacuum jacketed tank. A sheath is positioned over the cryogenic liquid filter within the tank for sterilizing the filter.

摘要： Provided are novel methods and systems for separating a mixed gas containing oxygen and chlorine. According to one method in accordance with the invention, the mixed gas and a refrigerant are introduced into a separator unit. At least a portion of the chlorine is condensed from the mixed gas in the separator unit, thereby forming a condensed chlorine-rich liquid fraction and an oxygen-enriched gas fraction. The condensing duty is supplied by the refrigerant, which can be liquid oxygen. The mixed gas and refrigerant can be brought into direct or indirect contact with one another. The invention can be advantageously applied to the treatment of exhaust gases from an ore treatment plant, and can result in enriched oxygen and chlorine streams which may be recycled or used in other applications.
