Abstract
A method of dehydrating natural gas and for reducing emissions of hydrocarbon aromatics including the steps of passing natural gas upwardly in an absorber against downwardly flowing liquid desiccant to provide treated gas, the desiccant absorbing water and hydrocarbon impurities from the gas and forming spent desiccant, passing a portion of the treated gas from the absorber through a desiccant stripper vessel, the balance of the treated gas being passed for distribution, heating the spent desiccant and passing it downwardly through the desiccant stripper vessel to purge the spent desiccant of hydrocarbon aromatics, conducting the spent desiccant from the stripper vessel into a reboiler to again heat the spent desiccant and conveying treated gas from the stripper vessel to a burner in the reboiler where the treated gas is combusted with air, the spent desiccant is being heated in the reboiler to boil off entrained water to provide a regenerated desiccant that is recirculated back to the absorber. The liquid desiccant can be recirculated by an electrically powered pump or by a glycol/gas powered pump.
