Gents, Thank you for the prompt replies. I had a copy of the Hydrocarbon Processing article you mentioned, and it is an example of why I turned to this forum for help. The article provides good information on corrosion mechanisms and the benefits of stress relief, but doesn't specifically...

Is PWHT necessary (or recommended) when using equipment & piping fabricated from 316SS or alloy 2205 in amine service (CO2 absorption)? There is a possibility that a small amount of chlorides may accumulate in the system which has me leaning toward 2205, but I can't seem to find an answer to the...

You have received some very good responses here. I am a little late in replying to your post, but have nearly 30 years experience in the chemical industry and as many of the other post contributors here, have experienced the hazards of steam firsthand. Things that CANNOT be over-emphasized are...

CGA G-2.1 Section 5.5.6 specifies that an opening in an anhydrous ammonia "container" need not be equipped with an excess-flow valve if the opening is not larger than a No. 54 drill size. I interpret this to mean the VESSEL NOZZLE must be restricted to this size internal opening, rather than...

Without knowing actual process conditions, from your post it appears you will definitely need to consider two-phase flow in sizing the relief device. Several resources can be found on the Web for relief device sizing methods (it sounds like you have a variant of the basic "fire exposure"...

I am trying to locate a company who can provide "turn-key" non-destructive testing and inspection services for a small industrial anhydrous storage facility that has been idle for 3-4 years. In addition to the inspection of two storage vessels, functional testing of valves (primarily control...

You might look at Atlas-Copco also.

You don't mention the conditions under which your system operates (aside from temperature), but you might want to consider using a mag-drive (seal-less) pump.
