Abstract

The present invention is related to two alkanolamines mixture aqueous solutions industrial use, the compositions of which can be established on a wide values interval, either on units of percent by weight, molar concentration, et cetera, for selective purification, by means of cyclic-type industrial process comprising gas/liquid absorption and regeneration of absorbing solution by means of temperature increase, of gaseous currents mainly composed of light hydrocarbons. Particularly, invention refers to simultaneously composed mixtures by diethanolamine and methyldiethanolamine in water and to a process for acid gases efficient removal, such as sulfhydric acid and carbon dioxide, which are presented as contaminants in different hydrocarbon gaseous currents.
