Control and Simulation of A 13C Isotope Separation Process

Roxana M. Motorga, Vlad Muresan, and Mihail Abrudean

Abstract—This paper is presenting a control solution for the concentration of the 13C isotope, both at the output and inside of the separation column; the proposed solutions are a relay and a PID controller. The 13C isotope results after a distributed parameter process, specifically the chemical exchange process of the carbon dioxide and carbamate. The analytical solution that was determined in order to model the described process is simulated. The evolution of the proposed solution depends on two parameters: the position in the column height and the time. The reference model is simulated in order to reach to the desired concentration using an acceptable flow of solution. The tuning method for the PID controller is Ziegler-Nichols, based on the bipositional relay. The advantage obtained during this control process consists of the possibility of reaching the desired concentration of the 13C isotope at any point of height inside the separation column.
