METHOD OF DRIVING A CO2 COMPRESSOR OF A CO2-CAPTURE SYSTEM USING WASTE HEAT FROM AN INTERNAL COMBUSTION ENGINE

摘要

An integrated system and method for driving a CO 2 compressor to densify CO 2 captured from the exhaust gas stream of an internal combustion engine on board a mobile source of CO 2 includes operating a turbine that is operatively connected to the power input or drive shaft of the CO 2 compressor, and operatively connecting a motor-generator to the turbine for (a) recovery of any excess power when the turbine-generated power exceeds the CO 2 compressor power demand and (b) providing supplemental power when the turbine-generated power is insufficient to meet the CO 2 compressor power demand.
