|PCT/US2013/037748||PRAXAIR TECHNOLOGY, INC.||HASHI, Mohamed|
An air compression system and method for an air separation plant in which air is compressed in a series of compression stages and a temperature swing adsorption unit adsorbs water vapor and carbon dioxide. The temperature swing adsorption unit is situated at a location of the compression stages such that air pressure upon entry into the adsorbent beds is between about 400 psia and about 600 psia. Each of the adsorbent beds of the unit have a minimum transverse cross-sectional flow area that will set the air velocity of the air to a level below that at which adsorbent bed fluidization would occur. Such operation allows fabrication costs of the adsorbent beds to be reduced because less adsorbent and smaller adsorbent beds are required while power consumption will be at a minimum.

The present invention provides a chromatographic stationary phase material various different types of chromatography. One example chromatographic stationary phase is represented by Formula 1 [X](W)a(Q)b(T)c (Formula 1). X can be a high purity chromatographic core composition. W can be absent and/or can include hydrogen and/or can include hydroxyl on the surface of X. Q can be bound directly to X and can include a first hydrophilic, polar, ionizable, and/or charged functional group that chromatographically interacts with the analyte. T can be bound directly to X and can include a second hydrophilic, polar, ionizable, and/or charged functional group that chromatographically interacts with the analyte. Additionally, Q and T can essentially eliminate chromatographic interaction between the analyte, and X and W, thereby minimizing retention variation over time (drift or change) under chromatographic conditions utilizing low water concentrations.

A preceding oxidation catalyst device (21), a diesel particulate filter (DPF) device (22), the turbine (14) of a turbocharger, a preceding NOx selective reduction catalyst device (23), and a subsequent NOx selective reduction catalyst device (24) are disposed in the exhaust system of an internal combustion engine (10) in this order from the exhaust port side, and an ammonia-based solution feeder (25) is disposed on the inlet side or outlet side of the DPF device (22). The NOx selective reduction catalyst of the preceding NOx selective reduction catalyst device (23) is constituted of a catalyst comprising a rare-earth composite oxide, and the NOx selective reduction catalyst of the subsequent NOx selective reduction catalyst device (24) is constituted of a zeolite catalyst. By thus properly disposing the exhaust gas purification units, not only the percentage of NOx removal is improved in wide ranges from low to high temperatures and to high flow rates, but also the temperature of the DPF device (22) is kept high to increase the period and frequency of continuous regeneration, thereby reducing the frequency of forced regeneration of the DPF device (22) and the discharge amount of CO2 that generates during the forced regeneration.
