A method for removing polymer from an acid gas treating system comprising contacting an acid containing stream with an aqueous alkanolamine solution and hydrocarbon solvent to form a mixture of an alkanolamine rich solution having the acid gases or byproducts thereof contained therein and the hydrocarbon solvent, where the hydrocarbon solvent has about 60 to 100 volume % aromatics content; and about 50 to 85 volume % two ring aromatic content, based on the total volume of the solvent.
L'invention concerne un procédé d'élimination des polymères dans un système de traitement des gaz acides, consistant à mettre en contact un flux renfermant un acide, une solution aqueuse à base d'alcanolamine et un solvant à base d'hydrocarbures, afin de former un mélange renfermant une solution riche en alcanolamine contenant les gaz acides ou leurs dérivés, et le solvant à base d'hydrocarbures. Ce solvant à base d'hydrocarbures renferme 60 à 100 % environ en volume de contenu aromatique, et 50 à 85 % environ en volume de contenu aromatique à deux cycles, sur la base du volume total du solvant.
