Claim 7:
8. A process for treating, compressing, and sequestering various CO2 streams from a bio fermentation based facility, the process comprising:
directing, by a fermentation stream gas blower, a CO2 gas stream from a fermentation unit to a gas conditioning unit and a cooler;
conditioning, by the gas conditioning unit, the CO2 gas stream;
cooling, by the cooler, the CO2 gas stream;
compressing, by a sequestration compression unit, the CO2 gas stream into a compressed CO2 gas stream, the sequestration compression unit comprising a sequestration compressor and a dehydration unit; and
conveying, by the sequestration compression unit, the compressed CO2 gas stream towards at least one of a sequestration site, a storage tank, or at least one industrial user;
capturing, by a waste heat recovery unit, heat from a flue gas of one or more process units and directing a heating medium or steam towards a capture unit;
directing, by a process units flue gas blower, the flue gas from the one or more process units towards the capture unit;
cooling, by a gas-gas exchanger, the flue gas from the one or more process units before the flue gas enters the capture unit;
capturing, by the capture unit, the CO2 from the flue gas of the one or more process units.
