This can’t be explained in just a couple of sentences. If a major maintenance campaign is planned, it is necessary to consider transferring as much propylene as possible from within the system to the storage tanks for recovery before shutting down the system. When parking, pay attention to the balance of the utility systems ； Following a planned routine shutdown and adhering to the operating procedures, there are generally no major issues; attention should be paid to the dry gas seal system as well as the turning gear.
