Does catalytic or coker liquefied gas contain dimethyl ether?
Thread Content
I would appreciate it if experts could advise me: does catalytic or cokerized liquefied gas contain dimethyl ether? If it is present, what is the typical PPM level? Thank you
We have a methanethiol analysis item; I’m not sure if there is a dimethane analysis item as well.
Dimethyl ether is only available in purchased liquefied gas, and it is usually added by the seller.
Generally, dimethyl ether is not present; it is dimethyl sulfide instead. The specific content depends on the form of sulfur compounds in the liquefied gas
If catalytic cracking and coking are carried out using petroleum-based feedstocks, the products will not contain dimethyl ether. If coal-based feedstocks are subjected to catalytic cracking and coking processes, trace amounts of dimethyl ether may be produced, but it’s uncertain whether they can be detected. Dimethyl ether is generally produced by the dehydration of methanol molecules. In conventional petroleum processing, there is no significant amount of methanol, so dimethyl ether is not formed.
