Abstract:
A comprehensive energy system, comprising:a utility plant arranged to process fossil fuel, combustion air and cooling water, provided as inputs, to produce base load electric power, off-peak electric power, SO.sub.2 -containing stack gas, and process heat as outputs, and to accept as an input for distribution, on-peak electric power;a Br.sub.2 -steam-methane unit arranged to receive as inputs water, process heat from said utility plant, off-peak power from said utility plant and HBr, to produce said on-peak power for input to said utility plant, H.sub.2, O.sub.2 and Br.sub.2 ;a CO.sub.2 recovery and methanol synthesis unit arranged to receive as inputs stack gas from said utility plant, after cleaning of SO.sub.2 from that stack gas, process heat from said utility plant, H.sub.2 from said Br.sub.2 -steam-methane unit and electric power from said utility plant, to produce methanol as an output; anda Bunsen reactor arranged to receive as inputs process heat from said utility plant, SO.sub.2 -containing stack gas from said utility plant, Br.sub.2 from said Br.sub.2 -steam-methane unit, and electric power from said utility plant, to produce HBr provided as input to said Br.sub.2 -steam-methane unit, H.sub.2 SO.sub.4, and CO.sub.2 -containing stack gas, depleted of SO.sub.2 and provided as input to said CO.sub.2 recovery and methanol synthesis unit.
