摘要： A method and system for CO2 capture from flue gas uses an absorber vessel in which a flue gas stream containing CO2 is contacted with an ammoniated solution to remove CO2 from the flue gas, and a regenerator vessel in which CO2 is released from the ammoniated solution. Parasitic energy consumption of the system can be reduced by adding to the ammoniated solution a promoter effective to enhance the formation of ammonium bicarbonate within the ammoniated solution. The amount of ammoniated solution recycled from the regenerator vessel to the absorber vessel is less than that which would be required using the ammoniated solution without the promoter for removal of the same amount of CO2 from the flue gas.

C. and 500.degree. C. and at a pressure between 10 and 400 atmospheres for between about 0.01 and 10 minutes;(c) producing compounds which are environmentally acceptable or are amenable to further degradation by conventional disposal systems; and(d) optionally degrading further the compounds of step (e) by reaction in a conventional disposal system. The waste includes ordnance waste, process waste, agricultural waste and the like.

摘要： A process for hot or supercritical water oxidative decomposition of wastes, particularly halogenated organic compounds, is described. The process employs a heterogeneous reagent which accelerates the decomposition and is effective to neutralize acidic byproducts. The reagent is maintained in suspension throughout the reaction by operating at conditions of temperature and pressure at which the heterogeneous reagent is largely or fully insoluble in water, and preferably at which liquid water is not present. Production of potentially corrosive brine is also minimized by operating at conditions under which sodium chloride is insoluble.
