20080236391 | Cooling and Purification of Gas Streams - Process for purifying and cooling a gas stream comprising a dialkyl ester A) of an aromatic dicarboxylic acid, which comprises treating the gas stream with an aliphatic dihydroxy compound B) at a temperature less than/equal to the melting point of the dialkyl ester A) in a 1st stage and treating the gas stream with an aliphatic dihydroxy compound B) at above the melting point of the dihydroxy compound B) in at least one 2nd stage. | 10-02-2008 |
20100132555 | PROCESS FOR A GAS REMOVAL ZONE - One exemplary embodiment can be a process for increasing an efficiency of an acid gas removal zone. The process can include sending a sour gas stream including at least one gas to a first absorber providing an overhead stream absorbing the at least one gas; withdrawing a side-stream from the first absorber and passing the side-stream through a holding tank, a side-stream fluid transfer device, and a side-stream chiller before returning the side-stream to the absorber; and passing the first absorber overhead stream to a pump-around circuit for a second absorber. Usually, the pump-around circuit may include a flash drum, a pump-around fluid transfer device and a pump-around chiller before providing a slipstream to the first absorber and another portion to the second absorber. | 06-03-2010 |
20110079148 | METHOD AND EQUIPMENT FOR IMPROVING GLOBAL WARMING AND AIR POLLUTION - A method and an equipment for improving global warming and air pollution are proposed, wherein hot exhaust gas generated by a thermal machine is injected into an exhaust boosting unit to be compressed and mixed with a liquid medium for atomization. Pollutants in the hot exhaust gas and heat generated due to combustion are adsorbed by the liquid medium. After the liquid medium passes a dust collecting unit, the pollutants adsorbed by the liquid medium will adhere to the dust collecting unit. Humid and hot clean air is extracted to the atmosphere, and rises to high altitudes and is cooled there. Water will drop to the ground in the form or rain or snow to cool the ground temperature and remove other pollutants in the air. Heat circulation and water circulation can be sped up to improve the situation of global warming and render more water resource to the Earth. | 04-07-2011 |
20120234167 | Gas Scrubber Having an Integrated Heat Exchanger - A gas scrubber, equipped with heat exchanger surfaces constructed of thermoplates, suitable for cooling and cleaning a hot gas by avoiding an excessive thermal load of the washing liquid. | 09-20-2012 |
20130118351 | AIR POLLUTION CONTROL SYSTEM AND METHOD | 05-16-2013 |
20130186272 | AMMONIA CAPTURING BY CO2 PRODUCT LIQUID IN WATER WASH LIQUID - A method for capturing ammonia present in combustion flue gas subjected to carbon dioxide removal, using a water wash unit ( | 07-25-2013 |

20100126349 | REDUCED TEMPERATURE SCRUBBING OF EFFLUENT GAS - Systems, apparatus and methods are provided involving a reduced-temperature wet scrubbing system adapted to scrub effluent gases within an abatement system. The reduced-temperature wet scrubbing system may include a wet scrubber adapted to be operated within a range of reduced temperatures and a cooling system adapted to maintain the wet scrubber within the range of reduced temperatures, which is below 23° C. The cooling system may include a coolant, preferably chilled water, adapted to cool the wet scrubber. The wet scrubbing system further may include an indication device, such as a temperature sensor, to indicate whether the wet scrubber is within the temperatures range. A controller in communication with the indication device may be provided to control the cooling system. In addition, the wet scrubbing system may include baffles and nozzles spraying chilled mist along a path of the effluent gas between an abatement tool and the wet scrubber. | 05-27-2010 |
20120152120 | PRODUCTION OF CARBON DIOXIDE FROM SYNTHESIS GAS - The present invention provides a series of processing steps to remove carbon dioxide from synthesis gas. The syngas exiting a hydrogen sulfide absorber is first compressed, subjected to a dehydration step and a low temperature liquefaction and separation to remove carbon dioxide. The high pressure syngas then continues on to a carbon dioxide absorber for carbon dioxide removal. The system can operate with lower solvent rates and equipment sizes compared to prior art systems. | 06-21-2012 |
20130125752 | Down-Flow Direct Contact Cooler - Systems and methods are contemplated for down-flow cooling of a feed gas. Contemplated systems can include a housing having an inlet conduit disposed within an upper portion and configured to receive a first stream. First and second stages can be disposed within the housing, with the first stage disposed upstream of the second stage and having a first cooling stream, and the second stage having a second cooling stream that is colder than the first cooling stream. The housing can be configured such that the first stream is cooled by down-flow heat exchange with the first and second cooling streams to produce a conditioned stream depleted of at least a portion of water condensed from the feed gas. | 05-23-2013 |
20160051925 | AMMONIA CAPTURING BY CO2 PRODUCT LIQUID IN WATER WASH LIQUID - A method for capturing ammonia present in combustion flue gas subjected to carbon dioxide removal using a water wash unit included in a chilled ammonia process. The method includes combining a CO | 02-25-2016 |
