Trilok:

It would take an Excel Workbook to tell you what you want to know. Tell me your email address and I'll send you the subject Workbook on how to generate a vacuum. (Also, tell me your full name, location or country, and your industry or company name)

Art,

I too am interested in this application. I work for an alternative energy company (Hydrogenics Corporation, Mississauga, Ontario, Canada) and we are currently investigating the use of vacuum for a new process we are developing to generate hydrogen. Could you forward me a copy of this file? My e-mail address is jac_caz@sympatico.ca

I designed a three stage steam ejector during my college years in India, which was appreciated by one of the pharam companies in India. Can you send me your excel spreadsheet, I would like to compare my calculations.

Just curious to know how I did back then.

Hi, Mr. Montemayor

Me too..^^

I am interested in your Excel work book on the estimation of vacuum duties.
I have been referring to the UOP Manual - "MAXIMUM AIR LEAKAGE VALUES FOR COMMERCIALLY TIGHT SYSTEM." No description or discussion on its source and its applicability is made.

Mine is sgkim@3dsystem.com
Many thanks in advance.

Hello Art,

Vacuum system design & trouble shooting is a part & parcel operation in chemical engineering practice . Can you provide excel workbook as an attachment on this forum for rest of the members?
I think file size may be more than size specified in forum-board.Then, would you please send me vacuum file on following:

Please send me a copy to:
