ABSORBENT TO DRY AND CLEAN GAS OF CARBON SULFIDE AND CARBON DIOXIDE Russian patent published in 2011 - IPC B01D53/14

Abstract RU 2430771 C2

FIELD: process engineering.

SUBSTANCE: invention relates to gas, oil and chemical industries, in particular, to absorption drying of hydrocarbon gases. Proposed absorbent comprises alkanolethylene diamine, diethylene glycol and water. Absorbent alkanolethylen diamine is represented by mono isopropanol ethylene diamine, diisopropanol ethylene diamine, and diethanol dithylene diamine in the following ratio of components in wt %: alkanolethylenediamine - 20-30; diethyleneglycol - 65-75, and water making the rest.

EFFECT: higher absorbing capacity.
