# How do you plot McCabe Thiele diagram?

## How do you plot McCabe Thiele diagram?

Target product quality (composition) of the top and bottom products.

1. Step 1: Establish the Plot.
2. Step 2: Add 45 Degree line.
3. Step 3: Add Equilibrium Data.
4. Step 4: Choose Product Compositions.
5. Step 5: Add the Feed Condition Line.
6. Step 6: The Rectifying Section.
7. Step 7: The Stripping Section.
8. Step 8: Stepping Down the Plot.

## What is the assumption when using McCabe Thiele method in calculate the number of tray in distillation?

Thus the slope of the operating line for the stripping section is a ratio between the liquid and vapour flows in that part of the column. The McCabe-Thiele method assumes that the liquid on a tray and the vapour above it are in equilibrium.

What are the assumptions of McCabe-Thiele method?

the molar heats of vaporization of the feed components are equal; for every mole of liquid vaporized, a mole of vapor is condensed; and. heat effects such as heat of solution are negligible.

How do you find the reflux ratio from Mccabe Thiele?

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 are the assumptions of McCabe Thiele method?

Within this framework, the assumption that the saturated liquid and vapor enthalpy curves are parallel lines, apart from adiabatic and isobaric operation of the distil- lation column, is shown to be sufficient to derive all the major results of the McCabe-Thiele method including the constant molar overflow condition.

How do you find the minimum reflux ratio McCabe Thiele?

What is reflux ratio formula?

The reflux ratio is defined as the ratio of the liquid returned to the column divided by the liquid removed as product, i.e., R = Lc/D.

#### Which of the following shape represents the number of theoretical stages in McCabe-Thiele method?

Clarification: In the McCabe-Thiele plot, the number of theoretical stages required for a given separation is represented by the number of triangles that can be drawn between operating lines and equilibrium curve.
