Monte-Carlo Simulations of Centrifugal Gas Separation

The use of a Monte–Carlo formalism in a centrifugal gas process separation simulation provides an efficient predictor of dew-pointing as a function of the imposed radial pressure gradient. Previously, this was done by simply calculating radial pressure and then resorting to a separate equation of state routine for evaluating whether condensation will occur or not. In our model, we incorporate the potential energy associated with rotation of a gas element into the simulation along with molecular interaction terms. This enables us to predict when sufficient nucleation has occurred that condensed material forms—an important limit for stable operation of a gas centrifuge.
