Work Problem Propane-Propylene Splitter with Bottoms Vapor Compression. In our example of the propane-propylene splitter we worked on the case of compression of the overhead bottom. Work the same column using the same assumptions but with bottoms vapor compression. Note that a desuperheater is added in the vapor return. This is used merely for mathematical purposes, in a real column the superheated vapors would be returned directly to the column. The starting point is shown by figure...

The actual obtainable heat work ratio should be about 50-80 of the ideal heat work ratio, for the given ATEX. An ideal heat work ratio of less than 10 at this point would be inauspicious, unless the heat flow is expensive. (3) Study the effects of pressure on capacity and separation in the column, and decide on a new column operating pressure from this. The new column needs to be sized, and a new reflux ratio assigned. Rework the ideal heat work ratio of Part (2) remembering to take into...
