Abstract

Se describe un procedimiento para la separación de dióxido de carbono a partir del gas del proceso de un oxirreactor, que comprende las siguientes medidas: i) introducción de un gas del proceso con contenido en olefinas, aldehídos y dióxido de carbono de un oxirreactor en un pre-lavador, ii) tratamiento del gas del proceso en el pre-lavador con una disolución acuosa que contiene alcoholes, aminas y/o aminoalcoholes, para separar aldehídos del gas del proceso, iii) introducción del gas del proceso liberado de los aldehídos en un absorbedor de una instalación para el lavado de gases dispuesta a continuación del pre-lavador, con el fin de separar dióxido de carbono del gas del proceso, y iv) tratamiento del gas del proceso en el absorbedor con una disolución acuosa con contenido en amina y/o aminoalcohol, y separación de dióxido de carbono a partir del gas del proceso. El procedimiento representa una mejora de procedimientos conocidos al poder reducirse claramente la formación de espuma en el absorbedor de la instalación para el lavado de gases.A process for the separation of carbon dioxide from the process gas of an oxirreactor is described, which comprises the following measures: i) introduction of a process gas containing olefins, aldehydes and carbon dioxide from an oxreactor in an pre-scrubber, ii) treatment of the process gas in the pre-scrubber with an aqueous solution containing alcohols, amines and / or amino alcohols, to separate aldehydes from the process gas, iii) introduction of the process gas released from the aldehydes in an absorber of a gas washing facility arranged next to the pre-scrubber, in order to separate carbon dioxide from the process gas, and iv) treating the process gas in the absorber with an aqueous solution containing amine and / or amino alcohol, and separation of carbon dioxide from the process gas. The process represents an improvement of known procedures as foam formation in the absorber of the gas washing facility can be clearly reduced.
