The capture of excess CO2 from the atmosphere is of paramount importance as this gas plays a key role in global warming and brings about severe problems. In this paper, the CO2-to-methanol conversion process as a feasible way to consume the captured CO2- was studied. The effect of different components of the inlet stream was examined. Another significant parameter is pressure, and the effect of this parameter was studied as well. According to the data obtained from this simulation, operating pressure has a reverse impact on production yield. By increasing the operating pressure, the lower conversion was obtained. On the other hand, the concentration of CO2 affects the conversion positively, and on the higher concentration, we achieve a higher conversion rate. This process is simulated using Aspen HYSYS V 8.8 for modeling and simulating of conversion of carbon dioxide to methanol. For this purpose, Peng Robinson is used as the fluid package; since it has shown better performance and less error when dealing with hydrocarbons in comparison with other equations.
