Dehydration of methanol to dimethyl ether
Thread Content
What are the requirements for the methanol feedstock in the process of converting methanol into dimethyl ether? Is high-purity methanol necessary?
Of course, pure alcohol is better. When using pure alcohol, it is important to pay attention to the concentration; 90% or higher is sufficient.
Dimethyl ether produced from phenol has a mild odor
Pure methanol is definitely better; it’s a good deal in the market right now
This is mainly determined by the design process. Of course, pure methanol is the best, but it’s not necessary. For example, our factory uses crude alcohol to produce dimethyl ether, and this is a common practice nowadays; however, it may not always be possible to obtain crude methanol from the market. Calculate the cost
All of them can be used, but crude methanol has a complex composition that can easily cause corrosion in the vaporization tower; moreover, the color of the dimethyl ether product may not be good either
