Rigorous Dynamic Simulation of Cryogenic Distillation of Hydrogen Isotopologues in the Fuel Cycle of a Thermonuclear Reactor Based on UV Flash
'Informa UK Limited', 2024Co-Authors: Ovcharov A., Szczepanski R., Kosek J., Pedrosa N., Lu X., Basili L., Lo Frano R., Aquaro D.Abstract:Operation of the fuel cycle of a thermonuclear fusion reactor naturally leads to accumulation of surplus protium, but in some cases it can also lead to accumulation of surplus deuterium. Both surplus protium and deuterium have to be separated, detritiated, and discharged to the environment, normally passing a final detritiation stage based on either the liquid phase catalytic exchange or water distillation process. The concept of a multicolumn cryogenic distillation (CD) system capable of discharging a time-varying surplus of deuterium is presented in this paper. A model of a CD column based on a UV (internal energy U–volume V) flash formulation and equation of state (EOS) thermoDynamic model for hydrogen isotopologue mixtures is also presented at the principal step to a comprehensive model of the isotope separation system. Although fundamental for constant volume systems, the UV formulation of the thermoDynamic state has not been widely used in transient Simulations; in particular, for distillation Dynamics modeling, other approaches are much more common. At the same time, in helium cryogenics the UV formulation has gained wide usage in large-scale Dynamic Simulations. It is known from the literature that a UV formulation of the distillation problem is very challenging for a numerically stable implementation. To cope with this situation, we present our findings on the sources of numerical instabilities and approaches

aspen Dynamics Simulation of a middle vessel batch distillation process
Journal of Process Control, 2015Co-Authors: William L LuybenAbstract:Abstract Aspen Dynamics is a powerful Dynamic simulator that is widely used to explore the Dynamics and control of continuous processes around some steady-state design operating point. This paper explores its use to study the Dynamics of a batch process. The example studied is a middle-vessel batch distillation system for separating a ternary mixture. The batch system is operated by adjusting the two reflux flowrates (one from the reflux drum to the top of the upper column and the second from the middle vessel to the top of the lower column). The liquid inventories in the three drums vary with time. This paper shows how this batch operation can be conveniently simulated by first using the steady-state simulator Aspen Plus to correctly size the equipment. Then the file is exported into Aspen Dynamics where a Rigorous Dynamic Simulation can explore alternative control strategies by using the large library of control functions.
