Can dimethyl ether be removed in the light-end stripping tower?

Yes, dimethyl ether forms an azeotrope with the C3 components, and a small amount of it can be removed
Thanks, friend. I’m the one who did the alkylation
It can be removed – no problem! ! !
Given that the boiling point of dimethyl ether lies between that of C3 and C4, it can be removed, though some C4 is consumed in the process
Theoretically, it is possible as long as the appropriate temperature, pressure, and number of trays are used. However, in practical operation, it was found that there is a high proportion of isobutane at the top of the tower, resulting in significant losses of isobutane; moreover, the removal efficiency is not good, and a large amount of dimethyl ether remains at the bottom of the tower. This is for reference only
Yes, dimethyl ether is in the light components
