ABSORBENT FOR DRYING HYDROCARBON GASES Russian patent published in 2011 - IPC B01D53/14

Abstract RU 2417823 C1

FIELD: process engineering.

SUBSTANCE: invention relates to gas, oil and chemical industries, in particular, to absorption drying of hydrocarbon gases. Absorbent comprises polyalkanolethylenediamine of general formula: (CH₃-CH(OH)-CH₂)_x-NH₍₂._x)-CH₂-CH₂-NH₍₂._y)-(CH₂-CH(OH)-CH₃)_yor (HO-CH₂-CH₂)_x-NH₍₂._x)-CH₂-CH₂-N₍₂._y)-(CH₂-CH₂-OH)_y, where x=1-2, y=0-2, diethyleneglycol and water at the following ratio in wt % polyalkanolethylenediamine - 20-30; diethyleneglycol - 65-75, and water making the rest.

EFFECT: increased gas drying depth.
