ABSTRACT:
A method of low temperature regeneration of glycol used for dehydrating natural gas in a glycol dehydration system including the steps of passing natural gas against flowing glycol in an absorber vessel so that the glycol absorbs water from the gas, providing spent glycol and dehydrated gas, conducting the spent glycol into a reboiler vessel, feeding a portion of the dehydrated gas into a burner positioned within the reboiler vessel where the dehydrated gas is combusted to heat the spent glycol, conducting a first portion of dehydrated gas into a gas distributor located within a lower portion of the reboiler vessel, the gas distributor causing small bubbles of gas to move upwardly through the spent glycol within the reboiler to augment separation of water from the heated glycol, conducting a second portion of the dehydrated gas into an upper gas stripper vessel mounted within an upper portion of the reboiler vessel to contact the dehydrated gas with the spent glycol to further augment the separation of water from the glycol to provide dehydrated glycol followed by withdrawing the dehydrated glycol and passing the water vapor that has been removed from the spent glycol to the atmosphere, the dehydrated gas serving to gently but thoroughly agitate the heated spent glycol to augment the separation of water, thereby permitting the spent glycol to be thoroughly dehydrated without the glycol reaching its boiling point, thereby reducing evaporation of the glycol in the regeneration process.
