are a Significant Number of Options

In a previous paper (Jantes Jaramillo et al, 2012) we examined a how a multi-component mixture that had difficult separation tasks could be separated into its component parts. It was argued with mixtures having difficult separations capital cost considerations dominate. Consequently, the way in which such separations should be conducted needed to be identified first. This then led to a significant reduction in the number of viable schemes and identification of the better options was simplified.

In this paper attention is directed at systems that cannot be simplified in this manner and where a large number of options are available.
