Integrated system and process for effluent abatement and energy generation

摘要

The present invention relates to an effluent abatement/energy generation system, as well as a method, for abating a process effluent gas stream that contains one or more target compounds such as hydrogen gas, ammonia gas, isopropanol, and other volatile organic compounds that are readily oxidizable, and for concurrently generating energy using such process effluent gas stream. Such effluent abatement/energy generation system comprises a purification unit for removing components other than such target compounds from the process effluent gas stream, and an energy generation unit for generating thermal and/or electrical energy. Such energy generation unit may comprise a combustion assembly, such as a microturbine, for direct combustion or catalytic combustion of the target compounds to generate thermal and/or electrical energy. Such energy generation unit may also comprise a fuel cell for using the target compounds to generate electrical energy.
