In execution of the hydrostatic test of a pressure vessel is necessary to measure the perimeter of the equipment before and after the test?
Why? Where is write?
dougarthur42,
You have sure about that? In your opinion, the pH doesn't lowers in the process of expansion in turbine? Is not it the physiochemical phenomenon in the expansion of steam to reduce its ph?
It's strange that we have a superheated steam at pH of around 8 and its condensate after...
I would like to know why the steam lowers its pH in the process of expansion in turbine equipment? Could someone show me some literature that best explains this phenomenon?
IRstuff,
Do you already heard about: Kp = equilibrium constant in terms of partial pressure and its relationship with Kc = equilibrium constant in terms of concentration? { Kp = Kc.(RT)^n} ... Then, I think it can explain what I'm telling!
I don't know what's happening exactly, but the reduction of the pH in expansion of the turbine is a fact! No doubt about it!Perhaps a physical-chemical phenomenon? Perhaps an imbalance of ions H+ caused by the expansion of the steam turbine?
Contamination with ions or error read's interpretation...
Where, I worked the last year, after being expanded in the turbine condensing, the superheated steam's condensate generates a pH of about 3 and to be reused in the process needs to have its pH adjusted to about 8. This is done with the use of amine (usually morpholine). I would like to...
