Is it necessary to import the internal components for methanol separation in the methanol synthesis unit of coal-to-methanol projects?
Thread Content
Experts, is it necessary to import the internal components for methanol separators? Are there any domestic examples of the production of such components for 1.8 million tons of methanol separation capacity? Also, is the methanol separator important in a methanol plant? How great is the impact on the entire unit and the syngas compressor?
It’s not very clear whether domestic products have achieved any results. But from personal experience, if the methanol separator does not perform well in separation, it can lead to liquid entering the compressor, causing serious accidents ； At the same time, the separation efficiency is poor; the recycle gas contains too much methanol, and there are also many side reactions involving methanol
There are many domestic companies that specialize in methanol separation; some use a combination of ultrafiltration, fine filtration, and cyclone separation, while others rely on pure gravity sedimentation
