【Abstract】 Dynamic characteristics of Air Separation System influences the chararistics of IGCC plant seriously.The study of the characteristics of Air Separation System is important to the study of the control of IGCC plant.Distillation tower is the key device of Air Separation System.The mathematic model of distillation tower was built by plate plate means.The inflence that the amount of liquid nitrogen pumped did to the concentrtion of product gases had been done.The inflence that the amount of product oxygen pumped did to the concentration of product gases had been done.The dynamic response was studied when the amount of product oxygen did a step change.更多还原
