MTBE ion reactor temperature
Thread Content
The temperature at the very top of the ion reactor always fluctuates between 35 and 60 degrees; it is believed that the etherification reaction occurs when the temperature is high, while the reaction is less intense when the temperature is low. What causes the reaction to occur sometimes and not at other times? Feed temperature: 28 degrees
What ionic reaction is taking place? Thank you
Is there a reaction occurring in some area of the ion reactor, causing the medium at the outlet to be hot in segments?
The feed temperature is too low; it should be kept around 40°C to stabilize the pressure in the fractional distillation tower. Control the flow rate of the feed pump to keep it stable, etc
It doesn’t have to be an etherification reaction; it’s possible that the feed contains a high amount of water, which reacts with isobutylene (releasing heat)； Generally, at 28 degrees Celsius, etherification hardly occurs
It could be that the preheating temperature is too low, or it might be due to a flat flow
Unstable isobutylene content in the C4 feed, along with unstable methanol feed volume, causes fluctuations in the alcohol-to-olefin ratio, which in turn leads to fluctuations in the reaction temperature； Fluctuations in system pressure cause fluctuations in reaction temperature ； Effect of the fractionation tower
