| Abstract: | The domestic APC and optimization technology application in the ethylene splitter of 145kt/a ethylene plant is discussed. The improved advanced control model has been developed based on previous control strategy and operation experience in the ethylene splitter. Critical quality control, energy save and optimum control are performed based on the software measurement estimation of ethylene concentration. It is proved that the benefit is achieved because control is more stable and ethylene output is increased. |
