| Abstract: | The sequence control of cracked gas dehydration and control strategy of Propylene rectifier is introduced.Sequence control can accomplish automatically dehydration of cracked gas and regeneration of desiccating agent.These generation has the following procedures :depressure,purge,heating,cooling,re pressure and standby.The control strategy of propylene rectifier is realized by regulating the ration of reflux flow to propylene production flow.Gonsequently both high purity propylene and stability of propylene rectifier are achieved. |
