Question 8 [15%] Stream 1 is an equimolar mixture of A, B and C (hydrocarbons), where component A is the most volatile, and C the least. It is required to separate this stream into three liquid products, one of each component at at least 98 mol% purity. A young (and possibly inexperienced) engineer, prepared a simulation of his proposed process, shown below. Unfortunately, he did not succeed in converging the second column. What can he do to fix his problem (mark all correct solutions)? a. Change the active specification in T-101 from "comp recovery" to "reflux ratio." b. Increase the specified value of "reflux ratio" in T-100. k c. Change the thermo-property package used. d. Change the active specification in T-100 from "reflux ratio" to "comp recovery." e. Increase the specified value of "Comp Frac-1" in T-101. T-100_C_DUTY T-101_C_DUTY 4 2 T-100 R_DUTY T-101_R_DUTY 5 T-101 T-100
