In an FPSO the gas condensate contains water and mixed into the super dried export gas, it is still assumed that the contents of water in the total export gas exceeds the pipeline owner requirements. Preliminary it seems that the solution will be molecular sieves at the gas condensate streaming.
One suggested alternative is to operate the TEG (Tri Ethylene Glycol) gas dehydration plant at 140 bar(a) pressure, which means to install a column in the total gas and condensate stream. This has to our knowledge been tested in Brazil and other places. The Oilfield owner have experience that it leads to large losses of glycol into the gas streaming.
Our customer wishes to discuss the problems around this high pressure TEG system. Our question is whether you have experiences of such issues and subsequently may convey your experience summary to us. Provided viable solutions from existing plant(s) is likely to require tender(s) for the equipment at later stage.
