1. A system for treating, compressing, and sequestering various CO2 streams from a bio fermentation based facility, the system comprising:
a fermentation stream gas blower configured to move a CO2 gas stream from a fermentation unit to a gas conditioning unit and a cooler;
the gas conditioning unit configured to condition the CO2 gas stream from the fermentation unit;
a cooler configured to lower a temperature of the CO2 gas stream to assist in removing water and preparing the CO2 gas stream for compression;
a sequestration compression unit configured to compress the CO2 gas stream and convey the compressed CO2 gas stream towards at least one of a sequestration site, a storage tank, or at least one industrial user, the sequestration compression unit comprising a sequestration compressor and a dehydration unit;
a waste heat recovery unit configured to capture heat from flue gas of one or more process units and direct a heating medium or steam towards a capture unit;
a process units flue gas blower configured to move a flue gas from the one or more process units to the capture unit;
a gas-gas exchanger configured to cool the flue gas from the one or more process units before the flue gas enters the capture unit; and
an air blower configured to blow ambient air through to the gas-gas exchanger for cooling; and
the capture unit is configured to capture the CO2 from the flue gas of the one or more process units, the capture unit including a CO2 absorber and a liquid absorbent for absorbing CO2 from the flue gas.
