The steady-state and dynamic simulation of cascade distillation system for the production of oxygen-18 isotope from water

The steady-state and dynamic simulation models of cascade water distillation system for production of oxygen-18 isotope, are established. An open cascade process consisting of 5 distillation towers and more than 2000 theoretical plates, as shown in part (a), is introduced to test the models. The concentration distribution of 18O and Deuterium at each plate during the start-up period is shown in parts (b) and (c).117
