Point Efficiency for the Regeneration of Triethylene Glycol

Example 13.2.2 Point Efficiency for the Regeneration of Triethylene Glycol 

Let us continue with Example 12.1.2 and estimate the point efficiency for the regeneration of triethylene glycol(2) (TEG) from a mixture with water(l). 

SOLUTION The values of both Qj and Qji were determined in Example 12.1.2. The values were 

Armed with the point efficiency we may calculate the composition of the vapor above the tray as
