According to later versions of NACE MR0175/MR0103 there are temperture limits on the use of AISI 316 in sour environments. If I interpret NACE strictly then I am confined to temperatures below 60ºC. I am talking about a liquid amine stream loaded with H2S. For example 25%DEA in water at 95ºC...
This may be very obvious, but not to me I'm afraid.
I have a pump data sheet in front of me. It gives the product as crude oil with an SG of 0.752 @ 22ºC and a Vapour Pressure of 8.5 Bara at 22ºC. Under H2S concentration it gives '92250ppm v'.
My question is what does '92250 ppm v' really mean...
Can anybody point me in the way of data on gas solubility in lubricating oils (ISO VG 20-30 grades say). What I am particularly interested in is the solubility of Nitrogen and the relationship between solubilty and temperature. I had always assumed that as temperature increased gas solubility...
