True or False: During the reaction process in the polymerization reactor, if the instrument air supply is suddenly stopped, the control valve for the jacket circulation water should be in the closed position. ( ) Answer:×
During the reaction in the polymerization reactor, if the instrument air supply is suddenly interrupted, the control valve for the jacket circulation water should be in the closed position. ( X )
During the reaction in the polymerization reactor, if the instrument air supply is suddenly interrupted, the control valve for the jacket circulation water should be in the closed position. ( CHUO )
Error--------------------
Wrong; the reaction is exothermic. For safety reasons, the instrument air should be shut off, and the control valve should be opened to facilitate cooling
During the reaction in the polymerization reactor, if the instrument air supply is suddenly interrupted, the control valve for the jacket circulation water should be in the closed position. (X)
Answer: Wrong. Uncertain whether it is in the open or closed state
Wrong; aggregation is an exothermic reaction, and the circulating water control valve should be of the F.O type.
During the reaction in the polymerization reactor, if the instrument air supply is suddenly interrupted, the control valve for the jacket circulation water should be in the closed position. (Correct)
