20100139483METHOD AND SYSTEM FOR ULTRASONIC RESIN DEGASSING - A method and system for degassing a resin is provided. A degassing trough retains the resin, and an ultrasonic energy source applies ultrasonic energy to the degassing trough and resin. The application of ultrasonic energy to the resin reduces the amount of trapped gas bubbles contained within the resin.06-10-2010
20090044700Process for Producing Injectable Solutions by Degassing Liquids and the Use Thereof for Stabilizing Oxidation-Sensitive Substances - The invention relates to chemistry, in particular to pharmaceutical engineering, and more specifically to a method for degassing, in particular, to deoxygenating liquid, in particular aqueous media consisting in simultaneously in agitating an inert gas, in exposing a solution to a deep vacuum and to a ultrasound action and in heating it with a temperature ranging from 35 to 60° C. The inventive method makes it possible to obtain an aqueous medium whose oxygen content ranges from 4 to 0.4 mg/l for producing stable aqueous solutions of food or pharmaceutical products.02-19-2009
20090205488CYCLONIC LIQUID DEGASSING SEPARATOR AND METHOD FOR DEGASSING A FLUID MIXTURE - A method and cyclonic separator are disclosed for degassing a fluid mixture comprising a carrier liquid and gaseous and/or vaporizable components, wherein: the fluid mixture is accelerated in a throat section (08-20-2009

20100089232Liquid contactor and method thereof - The invention relates to a gas liquid contactor and effluent cleaning system and method and more particularly to individually fed nozzle banks including an array of nozzles configured to produce uniformly spaced flat liquid jets shaped to minimize disruption from a gas. An embodiment of the invention is directed towards a gas liquid contactor having a plurality of modules including a liquid inlet and outlet and a gas inlet and outlet. An array of nozzles is in communication with the liquid inlet and the gas inlet. The array of nozzles is configured to produce uniformly spaced flat liquid jets shaped to minimize disruption from a gas flow and maximize gas flow and liquid flow interactions while rapidly replenishing the liquid.04-15-2010
20100089231Apparatus and method thereof - The invention relates to a gas liquid contactor and effluent cleaning system and method and more particularly to an array of nozzles configured to produce uniformly spaced flat liquid jets with reduced linear stability. An embodiment of the invention is directed towards a stability unit used with nozzles of a gas liquid contactor and/or an enhancer for stable jet formation, and more particularly to reducing the stability of liquid jets formed from nozzles of the gas liquid contactor. Another aspect of the invention relates to operating the apparatus at a condition that reduces the stability of liquid jets, e.g., a droplet generator apparatus. Yet another aspect of the invention relates to operation of the apparatus with an aqueous slurry. Still another aspect of the invention is directed towards to an apparatus for substantially separating at least two fluids.04-15-2010
20110174155METHOD FOR REMOVING SULFUR FROM A GAS STREAM - A method for removing elemental sulfur from a hot gas stream, such as an autoclave vent gas, while simultaneously cooling the gas stream. The method results in conversion of sulfur in the hot gas stream to the form of solid, non-sticky sulfur allotropes such as rhombic sulfur while avoiding formation of sticky sulfur allotropes such as monoclinic sulfur, thereby avoiding scaling and fouling of plant equipment. According the method, the hot gas stream is contacted with an aqueous medium containing a particulate material inside a quench vessel having a first inlet for the hot gas stream, a second inlet for the aqueous medium, and an outlet for removing a sulfur-containing liquid fraction from the vessel. At least a portion of the sulfur contained in the hot gas stream, along with other condensable materials, becomes incorporated into the aqueous medium and is subsequently drained from the vessel. The aqueous medium may comprise a slurry of tailings or other waste material, and the particulate matter contained in the aqueous medium may provide nucleation sites for the preferential formation of non-sticky solid forms of sulfur.07-21-2011
20090133575METHOD FOR THE TREATMENT OF SORPTION MATERIAL IN THE PURIFICATION OF SMOKE GAS IN BRICKWORKS - A method for the treatment of sorption medium in the treatment of smoke gas in brickworks is provided, in which smoke gas which has occurred during combustion is conducted through an exhaust air duct into which treated sorption medium, in particular limestone chips, is introduced. Treatment of the sorption medium involves introducing sorption medium into a mixer as initial material, the sorption medium being fresh material, partly saturated sorption material which has been recovered from the smoke gas, or a mixture of fresh and partly saturated sorption material. Additionally, a liquid, preferably water, is added to the sorption material directly in a mixer or before entering into the mixer.05-28-2009

20110126711Device and Method for Recovering Moisture in the Atmosphere - The invention relates to a device for recovering moisture present in the atmosphere. The device comprises a collection structure with a water recovery surface which during use at least partly makes an angle with respect to the orientation of gravity. Further, the collection structure is detachably couplable to a reservoir for storing the recovered moisture. In addition, the collection structure is nestable.06-02-2011
