| 20100224062 | CAUSTIC-ASSISTED SEAWATER SCRUBBER SYSTEM - The system uses seawater to remove sulfur dioxide from shipboard diesel exhaust gases. Structurally, the system includes a single-stage countercurrent scrubber with top and bottom ends. During operation, diesel exhaust gases are introduced into the bottom end of the scrubber and flow to the top end of the scrubber. Further, seawater is fed into the top end of the scrubber and falls to the bottom end while absorbing sulfur dioxide from the diesel exhaust gases. Thereafter, the exhaust gases exit the scrubber, substantially free of sulfur dioxide. Further, the extremely acidic effluent seawater exits the scrubber and is treated with caustic. As a result, the caustic neutralizes the seawater. Also, dissolved carbon dioxide may be removed from the effluent seawater to reduce the amount of caustic required for neutralization. In addition, an oxidizer may be used to reduce the chemical oxygen demand of the effluent seawater. | 09-09-2010 |
| 20110083556 | COMPACT WASTEWATER CONCENTRATOR AND POLLUTANT SCRUBBER - A compact and portable liquid concentrator includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. Fresh liquid to be concentrated is also introduced into the re-circulating circuit at a rate sufficient to offset the amount of liquid evaporated in the flow corridor. | 04-14-2011 |

The tank has, on its upper side, a gas-collecting chamber, in which the separated-off gases are collected and from which these are discharged. Likewise, the treated process water is discharged from the tank via a drainage means. | 10-31-2013 |

| 20160067649 | Process of Gas Containment - A process for capturing a target gas from a flowing gas mixture by use of at least a pair of capture and release sections together with a discharge section is described. The at least one pair of capture and release sections includes a target gas capture section and a target gas release section in fluid communication with one another. The target gas discharge section is in fluid communication with the target gas capture section. The capture, release and discharge sections have a high surface area medium and a fluid contained therein, and include a fluid entry point at a first end and a collection tank at a second end. The process comprises the steps of: directing a gas mixture through the target gas release section followed by the target gas capture section, wherein the fluid contained within the pair of capture and release sections allows for the target gas to be contained within a defined area between the capture and release sections; directing fluid through a first recirculation path from the collection tank of the target gas capture section to the entry point of the target gas release section and directing fluid from the collection tank of the target gas release section to the entry point of the target gas capture section, thereby recycling the fluid. The pair of capture and release sections include a concentration gradient of at least one of the target gas and the fluid. Further steps are: directing the fluid through a flow path, from the collection tank of the target gas capture section, heating the fluid and passing it through the discharge section to thereby release the target gas from the fluid within the discharge section due to the reduced solubility; and directing the fluid depleted of the target gas through a second recirculation path from the collection tank of the discharge section, and then to the entry point of the capture section. An apparatus is also disclosed. | 03-10-2016 |
