Greenhouse gases (GHGs) warm the surface and the atmosphere with significant implications for
rainfall, retreat of glaciers and sea ice, sea level, among other factors. Increased atmospheric CO2
concentration is widely being considered as the main driving factor that causes the phenomenon of
global warming. The chemical reduction of carbon dioxide is regarded as the most effective
method to reduce carbon dioxide concentration in the atmosphere. A steady-state heterogeneous
model for this methanol synthesis reactor was developed. This model is used to compare the
removal of CO2 in this reactor with a membrane dual type methanol reactor (MDMR) and
conventional dual-type methanol synthesis reactor (CDMR). A cascade membrane methanol
synthesis reactor is a vertical shell and tube heat exchanger in which the first reactor is cooled with
cooling water and the second one is cooled with synthesis gas. The wall of the tubes in the both
reactor is covered with a palladium-silver membrane, which is only permeable to hydrogen. The
simulation results represent 4.96% and 2.66% enhancement in the CO2 removal rate due to have a
favorable profile of temperature along the CMMR relative to CDMR and MDMR, respectively.
