Abstract:In a petrochemical project, the parameters of reactor discharge cooler in the reaction and C3 concentration unit are abnormal, which eventually leads to the shutdown of the unit. When the equipment is stopped for inspection after 4 months of operation, no problems have been found in the operation of the equipment. Within one month after the start-up, after more than 10 times of startup and shutdown due to unstable operation of the unit, the water and gas balance of the reactor discharge cooler is seriously unbalanced, and serious leakage occurs and the device stops. In this case, the factory and engineering company have analyzed the failure of the reactor discharge cooler.
