SATURATED GLYCOL SOLUTION REGENERATION METHOD Russian patent published in 2005 - IPC

Abstract RU 2257945 C1

FIELD: oil and gas production.

SUBSTANCE: invention relates to regeneration of saturated glycol solution used in the natural gas pre-transportation treatment and may also be employed for separating liquid thermolabile substances, whose destruction products are corrosion-active components. Regeneration is accomplished with the aid of mass-exchange column and evaporator. Glycol solution to be regenerated is first separated into at least two portions, of which one is used in unheated state as reflux for the mass-exchange column top vapors and finally gets into evaporator, whereas the rest of the glycol solution is heated and then fed directly into evaporator. Temperature of the column top vapors is controlled by amount of the cold portion of saturated glycol solution used as reflux.

EFFECT: lowered mass-exchange column corrosion intensity.
