Figure 2.1 McCabe-Thiele diagram ethanol-water at 1 atm - Comparison of operating lines used on D term 2007 versus operating lines generated from Rmin and total reflux 0

Figure 1.1: The McCabe-Thiele diagram used for calculating the number of theoretical steps. The y-axis shows the mole fraction of ethanol in the apvor phase, the x-axis shows the mole fraction in liquid phase. The upper curved line is the equllibrium line, while the straight line y=x is the operating line. The horizontal

the acetone-ethanol x-y diagram. For another system with an x-y diagram that has a more complex shape, more data points in the table may be needed. The McCabe-Thiele diagram is constructed by “stepping off stages.” The starting point is (x D, x D), which is the vapor composition ascending from tray 1. The liquid composition

The McCabe–Thiele graphical solution method for binary distillation is used to determine the number of equilibrium stages needed to achieve a specified separation in a distillation column. This method assumes: 1. The distillation column is adiabatic.

10 Apr 2010 — The mixture is ethanol and water and I need to use McCabe Thiele method. ... pinch point develops when you plot your McCabe Thiele diagram.

This Demonstration presents the McCabe-Thiele graphical method applied to the water-ethanol mixture. First, the rectifying (cyan) and stripping (magenta) operating lines are plotted using a reflux ratio equal to 1.5 times the minimum reflux ratio. These lines are derived by writing global and partial material balances around different sections ...

This article shows how to draw McCabe Thiele diagram for doing binary distillation analysis in a spreadsheet. Example. Determine total number of stages and feed stage for separation of a binary mixture with relative volatility (α) 2.5, Feed composition (z F) 0.36, Distillate Composition (x D) 0.915, Bottom composition (x B) 0.05 and feed quality (q) 1.5.

Figure 3: Example of stepping off stages using the McCabe-Thiele method Since ethanol is a appreciably more volatile than water, it is expected that a small number of stages will be necessary to separate these components. In addition, it is known that under maximum reflux, where the entire top product is

For this example I used the old classic ethanol and water problem. Step1: Open Aspen Plus and this is the first screen to pop up. Choose "Blank Simulation" an press "Ok" ... Txy diagram, depending on your components and property method, but this is not the same as the XY diagram we need for McCabe Thiele. Minimize the Txy diagram.

The purpose of this study was to investigate the separation of a binary water/ethanol solution via a continuous feed distillation column as a function of feed stage location and reflux ratio.
