A theoretical analysis is developed that is postulated before the study of the feasibility that a polluting gas, such as SO2, could be removed by an absorption process and then used or valorized as a commercial product after a joint process of subsequent desorption (stripping) stage. This Absorption/Deabsorption set could thus constitute an industrial plant for the generation of a commercial product (e.g., enriched SO2 or sulfuric acid), environmentally coupled with a large coal combustion plant.

Introduction
The process of absorption of gases has its reciprocal or inverse in what is called desorption (or here, “deabsorption” to distinguish from the too called desorption after an adsorption). In the present paper are addressed a brief definition of these processes and the intervening physical phenomena, so as the valorization of emissions such as those of SO2 that, at least theoretically, could be achieved. It then goes to a brief collection and analysis of theoretical approaches, design criteria and a particularized application for the deabsorption.
