15339972ExxonMobil Research and Engineering CompanyNarasimhan SUNDARAM

Systems and methods are provided for combined cycle power generation while reducing or mitigating emissions during power generation. Recycled exhaust gas from a power generation combustion reaction can be separated using a staged complementary swing adsorption process so as to generate a high purity CO2 stream while reducing/minimizing the energy required for the separation and without having to reduce the temperature of the exhaust gas. This can allow for improved energy recovery while also generating high purity streams of carbon dioxide and nitrogen.


2. 20170136409 USE OF CLINKER KILN DUST FOR GAS SCRUBBINGUS18.05.2017
B01D 53/68
15410007CalPortland CompanyHartmut Riess

Methods and apparatus for reducing the content of controlled acidic pollutants in clinker kiln emissions are disclosed. The methods and apparatus include introducing bypass dust produced during production of clinker into one or more locations between the preheater exhaust and the inlet to a dust filter including into a gas conditioning tower. Total bypass dust separated from the kiln exhaust gas may be used. The bypass dust can be separated into a fine and coarse portions. Fine or total bypass dust can be mixed with water to form a bypass dust slurry that can be introduced into the gas conditioning tower. Bypass dust can be used to reduce the content of acidic pollutants such as hydrogen chloride HCl and sulfur oxides SOx from clinker kiln emissions.

Disclosed are novel engineered fuel feed storks, feed storks produced by the described processes, and methods of making the fuel feed stocks. Components derived from processed MSW waste streams can be used to make such feed stocks which are substantially free of glass, metals, grit and noncombustibles. These feed stocks are useful for a variety of purposes including as gasification and combustion fuels.


5. 20170136404 CARBON DIOXIDE SEPARATION AND RECOVERY SYSTEMUS18.05.2017
B01D 53/04
15127592KAWASAKI JUKOGYO KABUSHIKI KAISHATakeshi OKUMURA

A carbon dioxide separation and recovery system includes an adsorption tower, a regeneration tower, and a drying tower. The adsorption tower causes a target gas to contact an adsorbent to adsorb carbon dioxide contained in the target gas to the adsorbent. The regeneration tower causes a normal-pressure wet gas which is a gas mixture of the carbon dioxide and steam to contact the adsorbent having adsorbed the carbon dioxide to desorb the carbon dioxide from the adsorbent. The drying tower dries the adsorbent. In addition, the carbon dioxide separation and recovery system includes a compressor that compresses the carbon dioxide, and an ejector that expands the carbon dioxide discharged from the compressor while suctioning negative-pressure steam, to generate the wet gas.

According to one embodiment, a water treatment method is a method configured to use a working medium that includes a draw solution and a water-containing solution to be treated. The draw solution is a hyperosmotic solution which generates an osmotic pressure difference with water. The method includes generating a flux of a mixture of water and a draw solution by an osmotic pressure difference generated between a solution to be treated and the draw solution in an osmotic pressure generator compartmentalized by an osmosis membrane, transferring the flux of the mixture to a vaporization-separation unit, separating the mixture into the water and the draw solution by a pressure difference, and recycling the draw solution separated by the vaporization-separation unit.

G01N 27/407
15417304DENSO CORPORATIONMikiyasu MATSUOKA

A catalytic conversion characteristic of a catalyst, which indicates a relationship between an air-to-fuel ratio and a catalytic conversion efficiency of the catalyst, includes a second air-to-fuel ratio point, which is a point of starting an outflow of NOx from the catalyst and is located on a rich side of a first air-to-fuel ratio point that forms an equilibrium point for a rich component and oxygen. A constant current circuit, which induces a flow of an electric current from an exhaust side electrode to an atmosphere side electrode through a solid electrolyte layer in a sensor element, is connected to the sensor element. A microcomputer controls a current value of the electric current, which is induced by the constant current circuit, based on a difference between the first air-to-fuel ratio point and the second air-to-fuel ratio point at the catalyst.

Systems and methods for using pressure swing adsorption to separate and/or capture resulting emissions are provided. A stream of recycled exhaust gas is passed into a first swing adsorption reactor comprising a first adsorbent material which adsorbs CO2. An enriched N2 stream is recovered from a forward end of the first swing adsorption reactor. The pressure in the first swing adsorption reactor is reduced. The first swing adsorption reactor is purged with a portion of the first N2 stream recovered from the first swing adsorption reactor. The first purge output is passed to a second swing adsorption reactor comprising a second adsorbent material which adsorbs CO2. A second N2 stream is recovered from the second swing adsorption reactor. The pressure in the second swing adsorption reactor is reduced. The second swing adsorption reactor is purged with a steam purge.
