It is very exciting to obtain methanol from CO₂ emissions as a by-product, especially when this by-product causes world environmental catastrophes and health problems. This paper is organized to present applicable solution for reduction CO₂ emissions through converting CO₂ emissions of refining plant to methanol by hydrogenation technology. Therefore, Aspen HYSYS simulation program was used for simulation of CO₂ capture plant and methanol production plant. The results achieved that 99% of CO2 emissions from refining plant were captured. As well as production of methanol with 99.99% purity of methanol; in addition, that CO₂ tones/one tone methanol of our work is less than previous work by 82.3%. Therefore, this paper presented an actual solution for reduction of CO₂ emissions and enhancing methanol production.
