| Abstract: | The approaches for energy conservation of delayed coker were proposed and analyzed according to the energy-use characteristics in the coking process. Based on three-link method for process integration and optimization, the retrofit of the 500 kt/a delayed coker in Shanghai Refinery was conducted by using the process simulation technique. The heat of coker gatch pump-around was increased to produce more 1. 0. MPa steam through the optimization of the pump-around, and the low-temperature heat was recovered to preheat the water from the river in the water treatment station. The above energy saving measures lowered the energy consumption and improved the economic profit of the delayed coker remarkably. |
