Question

A fermentation broth coming from the saccharification and fermentation reactor processing potatoes can be idealized as a mixture of 15% ethanol, 75% water, and 10% dextrin. Make a theoretical study calculating the possible vapor concentration that can be produced if this liquid mixture is heated to 80◦C. State all the assumptions you will use in dealing with this mixture. List down all the references that you will use for this problem.

ASSIGNMENT
Given:
	Ethanol = 15% , x1 = 0.15
	H2O = 75% , x2 = 0.75
	Dextrin = 10% , x3  = 0.10
	T = 80◦C = 80+273 = 353K
Step 1 - Antoine Equation for Ethanol
	A = 5.24677 , B = 1598.673 , C = - 46.424 , P = bar , T = K
	 
	log10(P) = A - B/ T + C  
      	log10(P1sat) = 5.24677 - 1598.673/353 - 46.424
	
	P1sat = 1.0768 bar
Step 2 - Antoine Equation for H2O
	
	A = 5.0768 , B = 1659.793 , C = - 45.
