We are in the process of evaluating transferring a sweet service oil emulsion skid to a sour field. The system will operate at ~30 psig and the vessel has a 50 psig MAWP. The vessel is internally coated, so I believe the vessel to be suitable for this application, but what about the piping...
What would be an acceptable level of oxygen in the inlet to an amine plant and/or a refrigeration plant with EG dehydration and hydrate inhibitor.
I know that the oxygen will react unfavorably with the acids in the amines and glycols causing corrosion, however I have not found what is high or...
Thanks for you input guys, it seems that there could be some oxygen in the inlet stream to this facility which I'm sure is causing some grief in this area. For curisosity sake, what is the tolerable limit for oxygen in the feed to a gas plant?
I have encountered a EG glycol system on a refrig plant that has a low pH approximately 5. What are some of the potential causes of this low pH and perhaps some solutions to keep it in a more normal range.
Thanks
