The energy consumption status of the fractionation column of 1 Mt/a delayed coking unit in Jiujiang Company was analyzed by Aspen process simulation software.Through optimizing the pump-round heat ratios to fully utilize the high temperature heat for increasing the temperature of feedstock entered fractionation column,the bottom temperature of the column was raised obviously.Thus,the consumption of furnace gas was reduced and the energy consumption of the unit was lowered significantly,which could provide a cost saving of 2 Million RMB annually.
