Design Code for Glycol Dehydration Units

Design Code for Glycol Dehydration Units

Design Code for Glycol Dehydration Units

(OP)
Hello Members;
I am in the process of collecting design information of a Gas Dehydration Unit (Glycol) for FFS evaluation. Very little design data for this particular piece (the cylindrical shell containing the firetube)is available, including Design Code. While researching in order to determine the usual Design Code applied, i learned that an API Spec (ANSI/API 12GDU, now withdrawn)is in existence. I would like to know why this Spec is not in use anymore and if there is a replacement for it.
Thank you in advance!

RE: Design Code for Glycol Dehydration Units

No idea why it was withdrawn but it can still be purchased on techstreet.com.

I don't think that API 12GDU would help you out anyway if you are doing FFS since the standard really was intended to talk about the process configuration of the package as opposed to the mechanical design of the components.

I believe that as far as design codes for shells and firetubes, I believe these would normally be ASME Section VIII.  I looked at 12GDU and didn't see any guidance on this subject in it.

RE: Design Code for Glycol Dehydration Units

the glycol regenerator opers less than 15 psig, so it is not covered by a code.
