摘要
Abstract
In order to study the economy of carbon dioxide catalytic hydrogenation large-scale methanol production plants,three representative processes(one methanol tower with circulation process,two methanol towers with circulation process and two methanol towers with circulation and small synthesis process)were taken as the research object,and 10×104 t/a methanol production capacity was taken as an example from three aspects:fixed asset investment,public engineering consumption and total cost.The economic efficiency of the three processes was analyzed and compared.The results show that the total cost of two methanol towers with circulation process is reduced by 5.3%compared to one methanol tower with circulation process and the total cost of two methanol towers with circulation and small synthesis process is reduced by 9.0%compared to one methanol tower with circulation process.In the total cost,hydrogen accounts from 46%to 52%,so hydrogen is the decisive factor affecting the total cost.When the price of methanol is 2696.9 CNY/t,the price of carbon dioxide is less than or equal to 0.4 CNY/m3 and the price of hydrogen is less than or equal to 0.7 CNY/m3,two methanol towers with circulation and small synthesis process is economically feasible.关键词
