I'm just wondering if anyone on here has any experience with a 90% gas stream through their dehy's. Since day 1 we've had hydrocarbon problems in our glycol, to the point where we actually physically skim the surge drums into a bin, consistently, even after 5 yrs of running. Our situation is recycling CO2 with 2 centrif compressors, obviously needing 2 dehy's before these that dry the aprox. 200 million of produced gas. We run through 2 inlet separators, then added 2 cyclone separators after that before the dehy's. We still have hydrocarbon problems in the glycol. We still skim the surge tanks, and actually have the surge tanks pressure up once in a while, from oil build up.
I guess there's quite a bit more info to give, but any suggestions would be helpful. We're told nothing is undersized.
