From the perspective of stirring, your analysis is quite reasonable. However, if you don’t stop the mixer and let it keep running, even though there are sufficient reaction conditions, the heat generated cannot be dissipated, which can lead to equipment corrosion; there are actual cases of this happening. ” Will it rise a lot here? Is there no cooling device?
The residual olefins in the reactor can cause the reaction temperature to soar; this should be considered improper operation, as standard procedures do not permit such a situation
Mainly, there is no refrigerant to carry away the excess heat
How can we avoid the problem of excessive or above-standard sulfur content in products due to delayed material release after a shutdown?
I see that on the reactors made by STRATCO, there is a cooling device specifically at one end?
Right, is it part of the standard operating procedures to keep the mixer running continuously?
There are two methods. One is to extend the cycle time of cyclobutane during the shutdown process, in order to carry as much of the olefins and oils present in the system as possible to the downstream system; this greatly reduces any further reactions that may occur within the reaction system after the shutdown； Another method is to drain the acid from the bottom of the reactor and the acid sedimentation tank after shutting down, and then reintroduce the acid before restarting the operation; this approach also allows for all the acid to be drained and not reused when the acid level in the system drops to 91. The above two methods are relatively effective solutions in production practice.
No, after the shutdown, all the power equipment in the entire system stops operating, except for the seal oil pump.
