Method and device for extracting volatile degradation products from the absorption circuit of a CO2 separation process

摘要

The method involves removing a condensate (6) by a downstream condensation process (5) during a desorption process (4), where degradation products (7) are purified to a large extent. A purified condensate (8) is formed, which is guided back to an absorption medium circuit (1). Cleaning of the condensate of degradation products is carried out by distilation process or by activated carbon wash process. An absorption medium (9), which is guided in the absorption medium circuit, is an aqueous solution of amine, amino acid, or potash. An independent claim is included for an apparatus for extraction of volatile degradation products from an absorption medium cycle by carbon dioxide deposition process.
