095150000 | Including foaming of liquid to aid in the separation | 6 |
20080271603 | Air purification system and method of purifying air - An air purification system and method of purifying air according to various embodiments of the invention includes an ambient air inlet and a purified air outlet for the passage there through of air via a transport line. At least one cleaning chamber configured to contain therein an aqueous solution containing a reactant medium is in fluidic communication with the transport line. The ambient air passes through the at least one cleaning chamber and bubbles through the aqueous solution reacting with the reactant medium contained therein to remove gaseous pollutants and/or particulates. To recharge the system, a user simply changes out the cleaning chamber when the reactant medium is no longer capable of reacting to remove the gaseous pollutants and/or particulates from air passing there through. | 11-06-2008 |
20100116137 | REMOVAL OF CARBON DIOXIDE FROM AIR - An air/liquid exchanger comprising an open-cell foam | 05-13-2010 |
20110011261 | WET SCRUBBER FOR CARBON DIOXIDE COLLECTION - A scrubber unit for removal of carbon dioxide from flue gas, including a first chamber, a second chamber, a partition dividing the first chamber and the second chamber, a first weir to distribute flow across of aqueous absorbent across the chamber, and a second weir in the second chamber. The partition is positioned to allow fluid to flow from the first chamber to the second chamber beneath a lower edge of the partition. The scrubber may be used in an algae growing system, along with an algae bioreactor, with the aqueous absorbent solution flowing in a continuous circuit through the wet scrubber and the algae bioreactor to absorb carbon dioxide in the wet scrubber and to provide the absorbed carbon dioxide to algae. | 01-20-2011 |
20120012002 | MONOTERPENE COMPONENT-RICH ESSENTIAL OIL, METHOD FOR PRODUCING SAME AND METHOD FOR REMEDIATING ENVIRONMENTAL POLLUTANTS USING THE ESSENTIAL OIL - To develop a means for effectively utilize terpene compounds contained in tree leaves, whereby branches and leaves cut in tree thinning and pruning can be effectively utilized as a resource. For this purpose, provided are a monoterpene component-rich essential oil containing 90% or more of monoterpene components; a method for producing the monoterpene component-rich essential oil which includes subjecting coniferous leaves to microwave steam distillation and collecting a distillate thus obtained; and a method for removing environmental pollutants which includes bringing the monoterpene component-rich essential oil into contact with atmosphere containing the environmental pollutants. | 01-19-2012 |
20130074694 | Bubble-Column Vapor Mixture Condenser - In a bubble-column vapor mixture condenser, a fluid source supplies a carrier-gas stream including a condensable fluid in vapor phase. The condensable fluid in liquid form is contained as a bath in a chamber in each stage of the condenser, and the carrier gas is bubbled through the bath to condense the fluid into the bath. The bubble-column vapor mixture condenser can be used, e.g., in a humidification-dehumidification system for purifying a liquid, such as water. | 03-28-2013 |
20140245887 | Absorber - An absorber is provided which uses a liquid solvent formed into a myriad of bubbles and micro-droplets. The solvent froth is a solvent for a selected component in an incoming gas stream. A plurality of spaced apart mesh assemblies is placed in one or more absorber tubes or in a reaction vessel. Using screens having cross-sections that are substantially rectangular wave in design together with proper operating parameters, the phenomenon of solvent pulsing is induced and maintained, maximizing efficiency of the absorber. | 09-04-2014 |
