20100326276 | ACID GAS SCRUBBING COMPOSITION - This invention provides novel compositions comprising substituted polyamines as acid gas scrubbing solutions and methods of using the compositions in an industrial system. The invention relates to the use of such polyamine compounds in industrial processes to remove acidic contaminants from natural and industrial fluid streams, such as natural gas, combustion gas, natural gas, synthesis gas, biogas, and other industrial fluid streams. The compositions and methods of the invention are useful for removal, absorption, or sequestration of acidic contaminants and sulfide contaminants including CO | 12-30-2010 |
20110100218 | Method for combining desalination and osmotic power with carbon dioxide capture - Carbon Dioxide capture processes utilizing ammonia, or ammonia in water as the capture fluid for carbon dioxide generate concentrated solutions of ammonium carbonate species in water, which are subsequently decomposed to capture the carbon dioxide and recycle the ammonia. Forward osmosis processes utilize ammonium carbonate species as draw solutions to pull water from saline solutions such as seawater in the ammonium carbonate solution. The ammonium carbonate solution is then heated to decompose the ammonium carbonate to ammonia and CO2 which are both reused, while a portion of the aqueous stream is recovered as pure water. Combination of carbon capture process with an integrated forward osmosis process provide great economies over standalone operations. Furthermore, the very high concentrations of ammonium carbonate provide a further opportunity to include osmotic power recovery cycles with the integrated forward osmosis and carbon capture process. | 05-05-2011 |

20130098245 | REMOVAL OF THERMAL STABLE SALTS FROM ORGANIC SOLVENTS - A Method for removing salts, which cannot be thermally regenerated in a temperature range from 0°-200° C., from organic solvents in aqueous solution by evaporation, wherein the normal boiling point of the organic solvents is higher than water. The organic components contained in the solvent and the salt-like components which are contained in the organic components are enriched by evaporating water and a portion of the organic components in a liquid phase which is formed in a first container. The salt-like components are concentrated in the liquid phase which is forming in the second container, and a partial stream of the liquid phase which is formed in the second container is discharged from the second container. | 04-25-2013 |
20130276631 | METHOD AND SYSTEM FOR REMOVING CARBON DIOXIDE FROM EXHAUST GAS BY UTILIZING SEAWATER - This invention relates to a method for removing carbon dioxide in an exhaust gas utilizing seawater, and to apparatuses for removing carbon dioxide by the method. The method includes producing a concentrated seawater having an increased concentration of salt by utilizing a reverse osmosis membrane method, producing an ammonia-saturating concentrated seawater by blowing ammonia into the concentrated seawater, contacting a non-heated exhaust gas with the ammonia-saturating concentrated seawater such that carbon dioxide is absorbed in the ammonia-saturating concentrated seawater, collecting a sediment of sodium hydrogen carbonate, and collecting ammonium chloride from a solution comprising the ammonium chloride produced by absorption of the carbon dioxide in the ammonium-saturating concentrated seawater. | 10-24-2013 |
20130319236 | A SCRUBBER SYSTEM FOR TREATING EXHAUST GAS IN A MARINE VESSEL AND METHOD OF TREATING EXHAUST GAS IN SCRUBBER SYSTEM OF A MARINE VESSEL - A scrubber system for treating exhaust gas in a marine vessel with a water based solution includes a first scrubber unit and a second scrubber unit, an exhaust gas inlet in the first scrubber unit and an exhaust gas outlet in the second scrubber unit and a second conduit section connecting the first scrubber unit to the second scrubber unit, a first scrubbing medium circuit and a second scrubbing medium circuit. The first scrubber medium circuit is provided with a source of scrubbing solution having a first connection to an outside of a hull of the vessel beneath the water line of the vessel and the second scrubber medium circuit is provided with a source of scrubbing solution having a source of fresh water in the vessel. | 12-05-2013 |
20140338533 | METHOD FOR SEPARATING OVERSPRAY - A method for separating overspray produced during the painting of objects, the overspray is absorbed by an air flow and transported to a separating surface of a separating device over which a separating liquid flows. A large part of the overspray merges with the separating liquid, is transported away by said separating liquid, and is removed from the separating liquid by separation. Separating liquid is fed to the separating surface using a dispensing device, which is arranged so that the total discharge mass flow (GM) of the separating liquid is dependent at least on the viscosity of the separating liquid. Furthermore, separating liquid having a predetermined inlet mass flow (ZM) is fed to the dispensing device, wherein the inlet mass flow (ZM) of the dispensing device is equal to the total mass flow (GM), and the viscosity of the separation liquid during the operation of the separation device is calculated. | 11-20-2014 |
20150107451 | Radon Removal From Gas - Radon is removed from a gas in an apparatus comprising: (a) a liquid-contacting apparatus having a shielded reservoir containing a fresh working liquid in which radon is soluble; and (b) a means for causing a stream of gas containing radon to pass through the liquid-contacting apparatus. When the radon level in the working liquid reaches a certain level, the working liquid is either taken out of service and stored until the radon level is reduced or the working liquid is diluted with additional working liquid having no radon. | 04-23-2015 |
