Hello

 

I am a third year ChemEng student, currently doing an equipment design project.

 

The unit I'm designing is a total condenser for anhydrous ammonia which uses cooling water, and I would like to use a vertically oriented spiral plate heat exchanger, however I'm struggling to find a design procedure which would include condensation. Would anyone be able to point me to a book/journal etc. which would outline such a procedure, or at least cover spiral plates in depth. 

 

I am currently in possession of the "Process Heat Exchange" by the Chemical Engineering Magazine and Kern's "Heat Transfer".

 

For anyone interested I'm attaching the equipment specification as a .docx file

 Equipment Specification FINAL lols.docx   17.92KB   34 downloads

 

Thanks for taking the time to help out a confused 3rd year...

Maqkwon:

 

I have downloaded and read your project specification and have a basic question to ask:  Why do you want to specify a spiral heat exchanger?  The project specs do not call for it.

 

Probably unbeknownst to you, the design capabilities and “know-how” for this type of special equipment lies in the realm of very specialized heat exchanger designer and fabricators.  The special and arcane information required to design such equipment is considered intellectual property of these companies and they are not about to reveal it to you.  There is no text book that I know of that teaches you how to design this type of exchanger.

 

My best advice to you is to select a conventional shell and tube type of exchanger (found in Kern’s “Process Heat Transfer”) and go with that.

I too agree with Art(sir) that you should be using S&T xchanger.

 

I made the project on Double Helical Heat Xchanger in my 3rd and 4th year.....and let me tell you whenever we make new projects and we have no guide to complete our knowledge for that specific project.....it is very difficult to cross the finish line.

 

I would suggest you to heed Art's(sir) advice and do your project....

 

If not click on below link and ask the forum............

PS: And I believe you will also be fabricating the Xchanger you are making.It would be costly for for you to make this Xchanger.Even if you are building this project in a group of 2-4.
