The rich glycol from the cold separators enters the reflux coils above the packing in the still columns of the ethylene glycol Re-boilers, where self refluxing occurs. The rich glycol is then passed through integral lean / rich glycol coils in the surge tank section of the Ethylene Glycol Re-boilers. After being preheated by the lean Ethylene Glycol in the accumulator, the rich glycol stream flows to the Glycol Flash tanks where any free gases that exist are flashed off and sent to flare. Any liquid Hydrocarbon that have been carried over to the flash tank is also removed utilizing the Hydrocarbon skimmer connection.
