 A new technology of methanol (MeOH) production by using carbon dioxide CO2 has changed world prospective regarding methanol production. These will contribute to the mitigation of CO2 which become the major gas in greenhouse gas. The study of this paper is to use quantitative risk assessment (QRA) for this process route to determine the risk tolerance levels, it acceptability in methanol production region and comparing to the old process route which used synthesis of natural gases. With the help of process simulators HYSYS, it can provide precise information regarding the process route at any given time. ALOHA software is implanted in this case study to help in identify the safe zone and vulnerability mapping of each of the process route. Lastly, by comparing the tolerance levels between new and old process route, it can determine which is more preferable to implemented in industrial production. © BEIESP.
