Cost estimation and prediction of CO2 and hydrogenated to green methanol
CO2 hydrogenation to green methanol is an important technology choice in carbon capture,storage and utilization technology.In order to predict the development trend of this technology,the project of CO2 hydrogenation to green methanol with an annual output of 100,000 tons was taken as the research object.Based on the calculation and analysis of the production cost and cost composition of CO2 hydrogenation to green methanol,the cost development trend of CO2 hydrogenation to green methanol was further predicted by Aspen Plus simulation calculation method.The results show that under the main economic indicators of 0.3 yuan/(kW·h)green electricity and 320 yuan/t CO2,the production cost of CO2 hydrogenation to green methanol is close to 3 950 yuan/t.In the next five years,the prices of green electricity and CO2 will be reduced to CNY 0.1/(kW·h)and CNY 200/t respectively.At the same time,considering the process optimization brought by the progress of methanol synthesis catalytic technology,the production cost of CO2 hydrogenation to green methanol can be reduced to CNY 1 618/t,which is 59%lower than the current level.The technology of CO2 hydrogenation to green methanol will mainly reflect the cost advantage and competitiveness with the decrease of green electricity price,and promote the green transformation of methanol industry.
