temperatures while reducing NOx emissions. Use of an NOx reducing agent and an N20 control agent, such as urea and monosodium glutamate, enlarges the temperature window for effective selective noncatalytic NOx reduction while significantly eliminating N20 emissions commonly experienced with urea injection. Further, the present invention discloses methods for controlling N20 emissions from stationary combustion systems having variable flue gas temperatures while reducing SOx emissions. Use of an NOx reducing agent, an SOx reducing agent, and an N20 control agent, such as urea, an alkaline-earth metal compound, and an alkalimetal compound, respectively, enlarges the temperature window for effective NOx and SOx reductions while significantly eliminating N20 emissions.

therefrom, and a control mechanism for opening and closing the bleed valve. When opened, the bleed valve preferably permits ambient air to admix with the gaseous process feed stream to form the blower feed stream. Increased blower gas throughput results in a lower magnitude gas temperature increase across the blower. The control mechanism used in the practice of the present invention involves monitoring the temperature of the blower effluent (or the gaseous feed to a downstream unit operation), and controlling operation of the bleed valve in accordance with that temperature reading.
5272879 5271507 STORAGE DISPOSAL SYSTEM FOR RECYCLABLE WASTE PRODUCTS Edward Evans A waste disposal system wherein a control panel inside a. building activates a series of spring loaded diverters which cooperate with a duct leading to a series of bins. Operator means is electrically connected to the control panel. When a user depresses a preselected contact means on the control panel, the diverter connected to it changes its position so as to allow access to a corresponding bin. The user can access different bins for separately storing cans, bottles, paper products, general trash and the like. The present system allows easy access to various bins, and encourages recycling by each householder.
5271557 METHODS AND SYSTEMS FOR GAS TREATMENT R Larr Lynch, Jeffre Powell assigned to Univar Corporation The present invention provides a process for decreasing the relative humidity of a gaseous or vaporous process stream, while increasing the temperature thereof. A preferred embodiment of the process of the present invention is implemented using a bleed valve, a positive displacement blower located downstream
MULTI-SYSTEM POWER GENERATOR B Rylan Wiggs A geothermal power system utilizes a fluid refrigerant capable of changing phase between liquid and gaseous states. The system includes a heat exchanger exposed to a heat source such as earth, water, air, or industrial waste for vaporizing the fluid in the heat exchanger. The heat exchanger includes at least two compartmentalized heat exchanger cells. Each of the heat exchanger cells is disposed in a portion of the naturally occurring heat source, the portions being sufficiently spaced apart such that a temperature of any one portion is substantially unaffected by a temperature of any other portion. The vaporized fluid is directed to a turbine or energy extraction means wherein the gas is expanded and energy is re)eased in the form of mechanical rotation of a shaft. The turbine shaft may be coupled to a generator for converting the mechanical rotational energy to electrical power. The gas discharged from the turbine is cooled/condensed and circulated into an accumulator, with a sensor and a controller for continuously maintaining the optimum amount of refrigerant flowing in the system under particular heat source/heat sink conditions. The liquid refrigerant is then recirculated to the heat exchanger, and the process is performed continuously. A compressor and sensored and controlled accumulator may be utilized in a second and separate refrigerant heat exchange loop with compartmentalized heat exchanger cells if necessary to maintain continuous output from the geothermal power system under all temperature conditions.
