| 20120036817 | Particulate Filtering with Filter Cartridges Having Cylindrical Segment Shapes - A filter cartridge which includes a filter medium having a cylindrical segment shape and a channel disposed within the filter medium for receiving fluid filtered through the filter medium. A method of increasing a filter medium surface area of a filter or lowering pressure drop across the filter that has a plurality of filter cartridges disposed in a filter vessel. The method includes removing at least one filter cartridge from the filter vessel and replacing the removed filter cartridge with a filter cartridge that includes a filter medium having a cylindrical segment shape. The latter filter cartridge also includes a channel disposed within the filter medium for receiving fluid filtered through the filter medium. | 02-16-2012 |
| 20120012006 | Pocketed Cyclonic Separator - A number of pocketed apparatus for separating various materials are described. A pocketed cyclonic separator that includes a cyclone chamber, which includes interior chamber walls, an inlet connected to the cyclone chamber, and one or more pocket separators, located on the interior chamber walls, is described. A substance may be introduced through the inlet into the cyclone chamber so as to create a rotational force sufficient to generate a cyclone in the cyclone chamber. Forces generated by the cyclone will cause heavier material in the substance to move towards the interior chamber walls when in use. The one or more pocket separators define one or more pockets that trap heavier material in the substance when in use. | 01-19-2012 |
| 20110262333 | Controlling ammonia flow in a selective catalytic reduction system during transient non-steady-state conditions - A selective catalytic reduction (SCR) system is defined that uses the measured concentration of reactant slip in the exhaust gas after SCR processing to control the amount of reactant injected during non-steady-state operational conditions. The SCR system works with a reactant slip detector located in the post-SCR processing section of the exhaust flue. The reactant slip detector measures the concentration of reactant in the exhaust gases and, based on that concentration, the amount of reactant injected into the pre-SCR processing exhaust gases is controlled. | 10-27-2011 |
| 20110158876 | INTEGRATED EXHAUST GAS COOLING SYSTEM AND METHOD - An integrated exhaust gas cooling system and method, including an expansion joint linking the system to an upstream source of exhaust gas and a pre-oxidation section through which exhaust gas travels. A hot temperature zone in which the exhaust gas is maintained at a temperature optimal for an oxidation process extends through the pre-oxidation section. An oxidation catalyst in the hot temperature zone is provided. The exhaust gas passes through the oxidation catalyst. Oxidized exhaust gas passes a post-oxidation section downstream of the oxidation catalyst. A tempering air stream is injected into the post-oxidation section to create a cool temperature zone in which the oxidized exhaust gas is cooled below the temperature in the hot temperature zone and to a temperature optimal for a reduction process. The system includes a reduction catalyst in the cool temperature zone through which the oxidized exhaust gas passes. | 06-30-2011 |
| 20100154980 | COMPOSITE VANE AND METHOD OF MANUFACTURE - A vane having a profile capable of formation by pultrusion is disclosed. The vane can be used for removing liquids entrained in a gas stream. The vane includes a main curved section oriented generally parallel to the gas stream and curved to reorient the gas stream, the main curved section causing a first and a second change of direction of the gas stream; a first air pocket formed on a first side of the main curved section, the first air pocket sized and oriented into the gas stream where the gas stream first changes direction; and a second air pocket formed on a second side of the main curved section, the second air pocket smaller than the first air pocket and sized and oriented into the gas stream where the gas stream makes the second direction change. | 06-24-2010 |
