Abstract: A process and system for low NOx cogeneration to produce electricity and useful heat. Fuel and oxygen are provided to an internal combustion engine (10) connected to drive an electric generator (9), thereby generate electricity. An exhaust stream is recovered from the engine. Fuel is added to the exhaust stream to create a fuel-rich mixture. The fuel enriched stream is provided to an afterburner (18) to provide a heated oxygen-depleted stream. The oxygen-depleted stream is cooled in a first heat exchanger (22). Conversion oxygen is admixed with the cooled stream which is then passed over a catalyst bed (25) under overall reducing conditions. The stream from the reducing catalyst bed is cooled and air is added to produce a further cooled stream and the further cooled stream is passed over an oxidizing catalyst bed (26) to oxidize remaining combustibles.

Abstract: A method for improved slurry-phase bioremediation treatment of organic sludge and mixtures of organic sludge and organics-contaminated soils by dissolving the contaminants into an aqueous phase and microbially degrading same. A high solids slurry of the sludge and soils is formed with water and an active bioslurry consisting of large populations of acclimated hydrocarbon-utilizing bacteria and small amounts of biodegradation residue. The slurry is passed through a plurality of in-series bioreactors in each of which a low hydraulic shear is maintained to promote the development of a large population of microorganisms that will form flocculent suspensions. The output from the series of bioreactors is flowed continuously or semicontinuously to a liquid-solids separator to partition the mixed liquor bioslurry from the biodegraded waste residue The mixed liquor bioslurry containing small amounts of biodegradation residue is returned to the slurry being processed for recycling. Off-gas components from the system are recirculated back to one or more of the bioreactors, to return high volatility toxic constituents for increased microbial degradation and control of volatile toxic constituent emissions from the process. The related system is also disclosed and claimed.

Abstract: A process for low NOX combustion which involves combusting an oxygen-containing combustible gas stream having fuel material in excess of the oxygen in the combustible gas stream, whereby the combustible gas stream is combusted in a reducing atmosphere to produce a heated oxygen-depleted gaseous stream, converting at least a portion of the heat in the oxygen-depleted stream into steam, adding air to the oxygen-depleted stream to produce a stoichiometric excess of oxygen in the resultant stream relative to fuel material present in the resultant stream, passing the resultant stream over an oxidizing catalyst to produce an oxidized gaseous stream, optionally removing heat from the oxidized stream, and venting the resultant cooled stream. A system for carrying out the foregoing process is also provided.
