How to adjust the levels of MSBE and polymers in MTBE? In the current MTBE production facilities, the levels of MSBE and polymers are very high – they account for over 40% of the total composition. Various adjustment methods have been tried, but these levels remain high. I hope experts can help identify the reasons for this
The high levels of MSBE and polymers are due to insufficient methanol amounts; increasing the alcohol-to-olefin ratio and controlling the reactor inlet temperature helps address this issue
For most problems related to high levels of MSBE and polymers, it is necessary to adjust the alcohol-to-olefin ratio; when there is an excess of MSBE, it is also important to consider whether the material is undergoing prolonged full reflux operation in the reactor, as such operations can also lead to an increase in MSBE levels.
MSBE issues are often caused by high reaction temperatures, or an alcohol-to-olefin ratio that is too high or too low; oligomer formation is usually due to a lack of methanol, and adjustments should be made according to the specific situation
The high polymer content is due to insufficient methanol amount; increasing the alcohol-to-olefin ratio, appropriately reducing the reactor inlet temperature to lower the backpressure, and increasing the line speed
