High pressure natural gas treatment plants

-cost - 10 MPa just around the #600 limit
-Pipeline pressure: Most pipelines in Europe operates around 70-80 barg
-Process: NG tends to go into dense phase around 100 barg. Som of these processes may not work as well then?

I've operated 1800 psi TEG units no problem. The treaters will work, I just do not know if the reaction and absortion data exists to acurately predict what happens at 15 to 20 MPa.

As for dense phase, just means a little bigger separator, nothing bad will happen.

OK - but the other two items are still correct I THINK.

You will have to install #900 flanges and most pipelines in Europe will allow #600 systems.

It seems that the most economical rating is the 600#, pressure and temperature rating per ASME B16.5. However, we have had recently to employ some Norsok flanges for the extreme ratings under the 600# class, particularly for those 30" (and larger) flanges, in order to keep the costs under control. I subscribe to the limit of 600#, otherwise the cost goes thru the roof...There is also another limit, for the Austenitic Steel sections, which have lower rating limit or the option of Duplex and higher...
