According to the results of conceptual studies, the energy
savings after heat integration were 57.8% and 54.9%, respectively.
The results were then placed back into the process and
the energy savings were estimated to be 34.3% and 32.2%,
respectively. Additionally, the energy consumptions for trireforming
and SCM processes were compared. The trireforming
process requires 19.0 kWh and SCM requires
11.5 kWh for every kg CO2 converted. However, the methanol
production rate from tri-reforming process was much higher
than that of the SCM process, suggesting tri-reforming process
will be a more economical and profitable way for the utilization
of CO2 in an industrial scale..
