The global methanol market size was USD ۲۷.۹۵ Billion in ۲۰۲۰ and is projected to grow from USD ۲۸.۷۴ billion in ۲۰۲۱ to USD ۳۹.۱۸ billion in ۲۰۲۸ at a CAGR of ۴.۵% during the ۲۰۲۱-۲۰۲۸ period. The methanol-to-olefins (MTO) reaction is one of the most important reactions in C۱ chemistry, which provides a chance for producing basic petrochemicals from nonoil resources such as coal and natural gas. As olefin-based petrochemicals and relevant downstream processes have been well developed for many years, MTO is believed to be a linkage between coal or natural gas chemical industry and modern petrochemical industry. Many institutions and companies have put great effort to the research of MTO reaction since it was first proposed by Mobil Corporation in ۱۹۷۷. Getting ethylene and propylene from methanol by the MTO process represents a major progress in chemical technology in recent years. This paper deals with the conceptual design of an energy efficient and cost-effective MTO process. Hence, we try to introduce the basic value chain management of Methanol to Olefin Process and hope to give the researcher a holistic approach to develop this research by mathematical modeling, system thinking approaches and so on. The economic evaluation results revealed that the conversion of methanol to olefins is more attractive for investment than the sale of crude methanol. The development of methanol to olefins units is more economical than constructing a new gas to ethylene, polyethylene and propylene unit because of the lower investment costs.
