Coal-based ethylene glycol production process
Thread Content
Hello everyone! I would like to ask whether the coal-based ethylene glycol process produces DMC (dimethyl carbonate) as a by-product There is no purification process – was it sold directly?
Yes. Of course, if you want to sell it at a high price, you need to purify it
DMC is a by-product; the purity level achievable directly in the system is too low. On one hand, its price is low, and on the other hand, it is difficult to sell. Currently, further distillation is used to achieve a purity of three 9s; achieving a purity of four 9s is quite challenging!

Dalian Rike uses catalysts containing nitric acid in the ethylene glycol production process, thereby saving resources. It works very well.
