In this study, the methanol synthesis process via trireforming
was investigated and rigorously simulated using
Aspen Plus. On the basis of specific flue gas composition, the
effects of reaction temperature, pressure, and CH4/Flue gas
ratios have been examined to determine the optimum conditions
of the tri-reforming process to produce syngas, which
is then converted to methanol. Additionally, heat integration
with different objective functions was performed to optimize
utility selection and energy costs. An economic analysis was
also conducted after heat integration to evaluate the potential
profits obtained through the integrated energy network.
