摘要： This invention proposes innovative techniques of NOx reduction in boiler operation through an adaptation of staged combustion in combustion boilers. In preferred processes, air is fed into an air separation unit, and a nitrogen-enriched stream is combined with air to produce a nitrogen-enriched first stage air stream, and at least a portion of an oxygen-enriched stream is mixed with air to produce an oxygen-enriched second stage air stream. A reduction in NOx and increase in efficiency is promoted by the inventive processes and systems.

摘要： Provided are systems and methods for separating a purge gas recovered from a polyethylene product. The method includes recovering a polyethylene product containing one or more volatile hydrocarbons from a polymerization reactor and contacting the polyethylene product with a purge gas to remove at least a portion of the volatile hydrocarbons to produce a polymer product having a reduced concentration of volatile hydrocarbons and a purge gas product enriched in volatile hydrocarbons. The purge gas product is compressed to a pressure of 2,500 kPaa to 10,000 kPaa, and is then cooled and separated into at least a first product, a second product, and a third product. A portion of one or more of the first, second, or third products is then recycled as a purge gas, to the polymerization reactor, or to the purge gas product enriched in volatile hydrocarbons prior to compression, respectively.

摘要： Carbon dioxide in combustion exhaust gas can be effectively separated and the combustion exhaust gas including the other exhaust gas components condensed through the separation of carbon dioxide can be discharged to the atmosphere.Air 7 is separated by an air separation unit 8 into oxygen 9 and other nitrogen-prevailing gas 10a. The obtained oxygen 9 and coal 1 are burned by a burner 5a of a combustion furnace 4. Exhaust gas treatment is conducted for the resultant combustion exhaust gas from the furnace 4. Then, part of the combustion exhaust gas is recirculated to the burner 5a and the remaining unrecirculated combustion exhaust gas is compressed to take out liquefied carbon dioxide 29. The other exhaust gas components 31 unliquefied through the compression is mixed and diluted with the other nitrogen-prevailing gas 10a in the separation of the oxygen 9 from the air 7 in the air separation unit 8 and is discharged to the atmosphere.

摘要： Hydrocarbons are recovered from the product purge gas in an alkene polymerization process by absorption of heavier hydrocarbons from the purge gas by an intermediate hydrocarbon stream to yield a vapor rich in inert gas and alkene monomer. Alkene monomer is condensed and rectified by dephlegmation at low temperatures from the inert gas, flashed and vaporized to provide refrigeration for the condensation step, and recycled to the polymerization process. The intermediate hydrocarbon from the absorption step is recycled to the polymerization process. Optionally a portion of the inert gas is reused for purge gas.
