How to design a distillation column for ethanol-water component by the feed of 95℅ solvent and the product of 99.5℅ solvent for 10KL per day.can anybody give me some idea about it

[Art Montemayor]

Mohammed:

 

To learn how to process design a distillation column you can do a variety of things:

 

• You can take a first year chemical engineering Unit Operations course in a university that offers such a study;
• You can purchase and study a book on the subject;  some books are:
  Douglas, James M., Conceptual Design of Chemical Processes, McGraw-Hill, 1988, pp. 453-457.
  Kister, Henry Z., Distillation Design, McGraw-Hill, 1992, pp. 275-282.
  Luyben, William L., "Introduction" in Practical Distillation Control (W.L. Luyben, ed.), Van Nostrand Reinhold, 1992, pp. 10-11.
  McCabe, W.L., J.C. Smith, P. Harriott, Unit Operations of Chemical Engineering, 5th Edition, McGraw-Hill, 1993, pp. 560-568.
  Seader, J.D. and Ernest J. Henley, Separation Process Principles, John Wiley, 1998, pp. 305-312.
• You can study the material found in many web sites on the internet.  One such site is Dr. Randel Price's (http://facstaff.cbu.edu/rprice/) and a sample of his lecture notes is attached.

An idea is use extraction with benzene.

[Nikolay_]

I apologize. Azeotropic distillation with benzene.

Hi,

I need help in designing a small scale ethanol distillation column. I'm not sure on what steps and calculations to follow. I have only decided to use valve trays. It would be a great help if someone could guide me on how do the design calculations.

 

Thanks in advance

Jay.
