The following stream at 100F and 480 psia is to be separated by two ordinary distillation columns
Question:
The following stream at 100°F and 480 psia is to be separated by two ordinary distillation columns into the indicated products.
Two different distillation sequences are to be examined. In the first sequence, CH4 is removed in the first column. In the second sequence, toluene is removed in the first column. Compute the two sequences in the following manner: Estimate the actual reflux ratio and theoretical-tray requirements for both sequences. Specify a reflux ratio equal to 1.3 times the minimum. Adjust isobaric column pressures so as to obtain distillate temperatures of about 130°F; however, no column pressure should be less than 20 psia. Specify total condensers, except that a partial condenser should be used when methane is taken overhead.
