What is the composition of the feed syngas in coal-to-methanol production?
Thread Content
I would like to ask the experts: after making changes in coal-to-methanol production, what are the appropriate proportions of hydrogen, carbon monoxide, and carbon dioxide as the feed gases for methanol synthesis?
Hydrogen minus carbon dioxide divided by carbon monoxide and carbon dioxide; a value between 2.05 and 2.15 is preferable
You want to know the H/C, right? It’s obviously 2. 05-2. Between 015. Here is a set of data on fresh gases; see if it’s useful: CO 30.48, H2 66.14, CO2 2.72, CH4 0.12, AR 0.15, N2 0. 39 This post was last edited by sdtzwh on 2009-3-14 15:57 ]
Are these numbers upstairs from actual production? How is the temperature of such a synthesis tower controlled?»
Factors that affect the tower temperature include the drum pressure, the circulation rate of the synthesis compressor, the amount of fresh gas, and the gas composition. Only by understanding these factors can the tower temperature be controlled stably.
