The energy consumption issues in coal-based synthetic ammonia and methanol production
Thread Content
I would like to ask everyone, what is the energy consumption comparison between coal-based methanol production and ammonia synthesis? What are the main differences in energy consumption among different processes?
By analogy under equivalent conditions: when the coal quality and gasification technology are the same, the supporting utility systems are also the same; the main differences lie in the subsequent processing stages – adjusting the hydrogen-to-carbon ratio (synthetic ammonia production requires thorough conversion to minimize CO content, while methanol production involves less extensive conversion), as well as purifying acidic gases (nitrogen is useful for synthetic ammonia production but inert for methanol production). Another major difference is between methanol synthesis and synthetic ammonia synthesis；
