It is very difficult to remove these impurities by using a catalyst column or an adsorption column. In this work a new purification method for SF6 mixture based on batch distillation is proposed. Experimental study showed good purification performance, where SF6N50 was obtained from SF6N30 feed. In the modeling of the batch purification process of SF6 mixture, the K-value was calculated based on the regular solution theory and a short cut method was employed. Results of simulations showed good agreement with those of experiments.

We propose a systematic procedure to achieve the optimal operation of a PSA process. The model of the PSA process for CO2 separation and recovery is developed first and optimization is performed to identify optimal operating conditions based on the model. The effectiveness of the

The model is based on the mass balance relationships written for the simplified wet-end white water network. The dynamic response of the wet-end is influenced both by the white water volume and by the level of wire retention. Effects of key manipulated variables
