Simulation Model for ASU Distillation Column of a 300 MW Oxy-Fuel Pulverized Coal Boiler

Abstract:

Based on a 300MW Oxy-fuel pulverized coal boiler,this paper established a dynamic mathematical model of air separation system distillation column, and compiled simulation procedure with the Fortran language on the platform of IMMS. With distillation column as the object of the research, it carried on a disturbance experiment about the outlet air flow of purifier and extractable volume of liquid nitrogen in lower tower. The results demonstrate that when the outlet air flow of purifier decreases, the nitrogen purity in gas is reduced by 0.39%, and the oxygen purity in liquid is reduced by 1.5%;when the outlet air flow of purifier is constant and extractable volume of liquid nitrogen decreases, the nitrogen purity in gas is increased by 0.2%, and the oxygen purity in liquid is increased by 0.06%.
