Dehy hydrocarbons
Dehy hydrocarbons
(OP)
First off, it's my first post and I'm actually operating an oil / gas plant. But do have 4th class boiler ticket and a 2 yr petroleum Sait course. Hope I'm not too stupid to be on here.
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.
Thanks

One thing to keep in mind, all the mechanical separators you'll every put in will have zero effect on components in the gaseous state. So if you have C5 in your inlet stream and the conditions stay right for it to be a gas you will have C5 in your outlet stream.
