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...

Info

This shows 3 efficiency is lost by the refrigeration cycle for this case. The characteristic of the refrigerant heat transfer fluid used is important on efficiency. The following list gives the desired characteristics listed in rough order of importance. 1 The vapor pressure of the fluid must be in a reasonable range for the desired temperatures. A vapor pressure of 0.1 psia or 5000 psia would make the fluid undesirable. 2 The liquid cannot freeze at the lowest temperature met in the cycle. 3 A...
