摘要： Sonication is employed in the destruction of organic chemicals, using liquid carbon dioxide as the sonicating medium. The process of the invention for decomposing at least one chemical comprises: (a) providing a sonicating vessel equipped with an array of sonicators; (b) introducing the chemical to be decomposed into the sonicating vessel, together with liquid carbon dioxide; and (c) exposing the chemical in the sonicating vessel to sonication for a period of time sufficient to cause the chemical to decompose to form at least one decomposition product. The sonication process may additionally employ one or more of ultraviolet light, oxidizing modifiers such as water, sodium hypochlorite, ozone, or hydrogen peroxide, and reaction-quenching species such as hydrogen (H.sub.2). Depending on the nature of the decomposition product(s), disposal may range from simple concentration of the product and collection thereof (in the case of liquids or solids), to venting to the atmosphere (in the case of gaseous, inert products), to venting to the atmosphere through an appropriate gas-trap (in the case of gaseous product that are toxic, reactive, or considered to be environmentally-controlled substances).
摘要翻译：超声处理用于破坏有机化学品，使用液体二氧化碳作为超声介质。用于分解至少一种化学品的本发明的方法包括：（a）提供配备有超声波器阵列的超声波容器; （b）与液体二氧化碳一起引入要分解成超声波处理容器的化学物质; 和（c）将超声处理容器中的化学物质暴露于超声处理一段足以使化学品分解形成至少一种分解产物的时间。超声处理方法可另外使用一种或多种紫外光，氧化改性剂，例如水，次氯酸钠，臭氧或过氧化氢，以及反应猝灭物质如氢气（H 2）。根据分解产物的性质，处理可以从简单的产品浓度和其收集浓度（在液体或固体的情况下）到排放到大气中（在气态，惰性产物的情况下）通过适当的气体阱（在有毒，反应性或被认为是环境控制物质的气态产物的情况下）排放到大气中。

摘要： A piece of soiled fabric is cleaned by contacting it with a jet of an ionized soil-dislodging gas to dislodge the soil therefrom. The ionized gas and the use of an oppositely charged electrostatic filter aid in preventing redeposition of the soil onto the fabric. The fabric may be agitated while it is contacted with the gas jet. A portion of the piece of fabric may be treated with an electrostatic spotting compound that enhances the effect of the ionized gas and may also enhance the removal of the soil. An apparatus for accomplishing the cleaning includes a container having an interior in which the fabric is received, a gas jet nozzle directed into the interior of the container, a source of a pressurized gas communicating with an inlet of the gas jet nozzle, a gas jet manifold extending from the source to the gas jet nozzle, and a gas ionizer disposed to ionize the pressurized gas passing through the gas jet nozzle.

摘要： A cleaning system and method utilizing sonic whistle agitation to enhance the soil removal and mass transport capacity of the liquid carbon dioxide at low process temperatures. Sonic whistles are within a cleaning chamber, and liquid carbon dioxide is forced out of the sonic whistle jets to ultrasonically emulsify and disperse non-miscible liquids or insoluble solids, such as remove low solubility oils and greases, in the liquid carbon dioxide contained in the cleaning chamber. Cleaning is accomplished at temperatures between -68.degree. F. and 88.degree. F., and the temperature of the liquid carbon dioxide is typically below 32.degree. F.

摘要： Fabrics are cleaned by treating at least a portion of the piece of fabric with a particulating chemical, and agitated by a gas jet of a particle-dislodging gas to dislodge the particulated soil. The particulating chemical loosens embedded non-particulate soil and converts it to a particulate form, which is then separated from the fabric by the particle-dislodging gas.

摘要： A process is provided for cleaning, disinfecting, and sterilizing substrates comprising the steps of: (a) placing the contaminated substrate in a cleaning vessel; (b) contacting the contaminated substrate with dense phase carbon dioxide in liquid form; (c) subjecting the substrate and the dense phase carbon dioxide to ultraviolet radiation having a wavelength within the range of about 180 to 300 nm for a duration and intensity sufficient to produce a photochemical reaction capable of destroying the DNA of microorganisms on the substrate; (d) substantially simultaneously subjecting at least the dense phase carbon dioxide to agitation; and (e) removing the dense phase carbon dioxide from the cleaning vessel and thereby transporting the contaminants from the substrate such that the substrate is cleaned and, in the case of contaminated garments, disinfected or, in the case of medical and dental instrumentation, sterilized. Substantially simultaneously with the UV exposure and agitation, the substrates are also subjected to an oxidizing sterilant, such as H.sub.2 O.sub.2.

摘要： Substantial amounts of particulate soils in garments can be removed by agitation in gas-jet in a solvent-free, low-pressure environment. The ability of the present gas-jet agitation system to remove particulate soils from garments and fabrics rivals that of conventional dry-cleaning processes which agitate the garments and fabrics while immersed in solvent. Thus, a dry-cleaning operation may consist of a solvent-immersion step for removing soluble soils and a gas-jet agitation step to remove particulates. Considerable savings in equipment and operating costs may be realized in the practice of the invention, since solvent flow rates need not be boosted to provide necessary agitation for particulate soil removal. The savings achievable by employing gas-jet agitation are even more pronounced in dense phase gas dry cleaning systems, which require pressurized environments to maintain a liquified solvent. Advantageously, the apparatus employed in the practice of the invention has no moving parts and is relatively inexpensive to fabricate and maintain. Further, the gas used as a means of agitation may be any commonly-available inexpensive gas, such as carbon dioxide, nitrogen, or air, so that the process is environmentally-friendly.

摘要： A method of replenishing liquid carbon dioxide solvent in a liquid carbon dioxide dry cleaning system or other dense phase carbon dioxide cleaning system. The method uses dry-ice or solid carbon dioxide, as a replenishing stock, thus reducing transportation, storage and handling costs. The method disposes solid carbon dioxide blocks in a cleaning chamber after a cleaning cycle. Liquid carbon dioxide solvent is boiled and is used to melt the solid carbon dioxide blocks. Liquid carbon dioxide solvent produced by melting the solid carbon dioxide blocks is pumped from the cleaning chamber into a storage tank to replenish the liquid carbon dioxide solvent.

摘要： An improved liquid carbon dioxide dry cleaning system containing an improved dry cleaning fluid. The dry cleaning fluid contains an antistatic agent for dissipating static charge on members or garments generated by friction during cleaning thereof. The concentration of the antistatic agent is typically less than 1 percent. Static charge present on the members or garments that are cleaned is transferred through the dry cleaning fluid to ground. This transfer of charge minimizes static charge buildup on the members or garments and suspended soil redeposition onto the members or garments. An odorizing agent or fragrance, and/or a deodorizing agent may be added to the cleaning fluid.
