How do you calculate reflux ratio from minimum reflux ratio?
Minimum Reflux Ratio (Rm) Draw a line from ( xD, yD) passing through ( x1, y1) with an intercept xD / (Rm + 1) on Y axis. Reflux ratio is calculated as 1.5 times the minimum reflux ratio.
What is VLE diagram?
Vapour-Liquid-Equilibrium (VLE) Curves. Constant pressure VLE data is obtained from boiling point diagrams. VLE data of binary mixtures is often presented as a plot, as shown in the figure on the right. The VLE plot expresses the bubble-point and the dew-point of a binary mixture at constant pressure.
How do you find the minimum reflux ratio from McCabe Thiele?
How do you determine the number of stages in a distillation column?
If we use partial reboiler and partial condenser, then the actual number of stages = but if we use total reboiler and total condenser, then the actual number of stages is the same as the actual number of trays So, the actual number of trays =13 and since we used in our calculation partial reboiler then the actual …
How is VLE data calculated?
Calculating VLE. Raoult’s Law in combination with Dalton’s Law are useful for determining VLE data of a binary mixture if the vapour pressure information are available. By repeating the calculations for several vapour pressures, we can obtain a series of x and y values from which the equilibrium curve can be plotted.
Can you graph equations in Excel?
You can use a similar technique to plot any function or equation in Excel. Simply choose a range of x-values to use in one column, then use an equation in a separate column to define the y-values based on the x-values.
What are McCabe-Thiele diagrams used for?
McCabe-Thiele diagrams are an indispensable aid to teaching distillation, as they graphically demonstrate key concepts (number of stages, feed location, minimum reflux ratio, etc.) related to operability of a distillation column.
What is the tray efficiency of the McCabe Thiele method?
100% tray efficiency. Trays calculated using the McCabe-Thiele method are called “theoretical trays”. In practice fluids do not reach equilibrium on each tray, and so the “tray efficiency” is used to determine the number of actual trays required to make a given separation.
What is the McCabe-Thiele method?
It is a method for calculating the number of theoretical trays required for the distillation of a binary mixture. This article describes how to apply the McCabe-Thiele method.
What are the assumptions of the McCabe-Thiele distillation method?
The McCabe-Thiele method is a very simplistic model of distillation and subject to the following assumptions: The mixture is binary i.e. there are only two components. The heat of vaporization of the two components are equal (When one mole of the heavier component is vaporised, one mole of the lighter component is condensed).
