A method for reducing hazardous gases exhausted from a process chamber includes an effluent gas treatment system with a gas energizing reactor and an additive gas source. The communication system includes a first group of one or more remote devices that interface with a local host in accordance with a first protocol and a second group of one or more remote devices that interface with the local host in accordance with a second protocol. In the case of a carbon dioxide -containing methane gas as an impure feed gas, contacting, in the stripping stage, the solvent effluent from the absorption stage with a recycled vapor fraction of the solvent effluent from the stripping stage can improve the recovery and purity of not only the methane, but also that of the CO2 contaminant gas. Incoming fuel passes through a fuel chamber, separated by a membrane from a pressure chamber, which in turn is connected to the intake pipe.
