Coal-to-methanol purification process
Thread Content
I need to create a small design for a purification process for coal-based methanol; can anyone provide some information on this topic? It mainly involves the design and calculation aspects of its equipment – what processing method is the most feasible to choose?
It’s a pity I can’t upload the materials; otherwise I could give you valuable first-hand information. Currently, most of the processes involve low-temperature methanol washing; it is a mature technology that is simple to operate and stable in performance.
Transformation + low-temperature methanol washing + sulfur recovery will suffice. Can the low-temperature methanol washing process use the technology from Dalian University of Technology? For sulfur recovery, Shandong Sanwei offers low investment costs and meets environmental standards! I’m not sure which company in China has more mature technology for this transformation; it’s provided for reference only
For large-scale projects, a full low-temperature shift conversion process combined with low-temperature methanol washing and Claus sulfur recovery is sufficient, which is quite good.
The all-low-temperature transformation is an excellent catalyst developed by Hubei Institute of Chemistry, and the associated process is also well-established；
