Dimethyl ether reactor temperature excursion
Thread Content
Who can provide a detailed explanation of the process surrounding the runaway temperature in dimethyl ether reactions? ? And what causes the temperature to rise? ?
Has anyone never worked with dimethyl ether? ? Bring in an expert, please! ! ! !
Let’s first talk about the specific details of your reactor; otherwise, the topic is too broad and I don’t know where to start.
Reply to 3# DXJ122: Our reactor is a three-stage quench type fixed-bed reactor
Reply to 4# Yunying: Thank you for sharing your introduction. The issue of excessive temperature rise in such reactors is quite complex; it would be better to let those who have experience in designing them discuss it first. I think they have done calculations regarding heat removal and taken precautions into account.
There isn’t enough cooling capacity; the temperature of the gas entering the tower is high. The catalyst bed reacts well, but heat cannot be dissipated. Is the load too high? Adjust the cooling gas and operate at the designed load level, and that should solve the problem
There’s usually a steam temperature control line, right?
