Partial condenser not a stage
WebThis Demonstration shows a depropanizer with three components: propane, -butane, and -pentane. The depropanizer has a total condenser, a partial reboiler, 20 equilibrium stages, and operates at 17 bar. The feed stream, a saturated liquid at 101.6 °C, enters the depropanizer at stage 11 at a flow rate of 100 kmole/hr. WebThus, the optimal stage for the membrane draw stream (NMF) is not the bottom stage. Figure 2 (a) also shows that, for a fixed membrane feed flow rate (10 or 50 kmol h − 1 ), increasing the stage cut (from 0.1 to 0.5) increases the effect of the membrane, resulting in a lower column condenser duty.

The pressure of the condenser … WebIt allows up to four feeds connected to different stages of the column and up to two optional side extractions. Total or partial condenser and partial reboiler are implemented. When partial condenser is selected, the distillate is withdrawn vaporized. Murphree efficiency allows for non-equilibrium behavior on each stage.
WebThe vapor distillate product is 99.9 mol% n-pentane and the bottoms product is 99.9 mol% n-hexane. The system has a partial condenser (thus the distillate product is a saturated vapor) and operates at an external reflux ratio of Lo/D = 2.8. The reboiler is a partial reboiler. Find D, B, QC and QR.
