APPARATUS AND PROCESS FOR PURIFICATION OF A NITROSAMINE-CONTAMINATED PRODUCT FROM A CO2-CAPTURE-PLANT

摘要

The method involves heating a contaminated product on a temperature and destroying the nitrosamines in thermal manner. The temperature is higher than a maximum temperature in the process plant, where potassium hydroxide is fed as leach (5). The contaminated product is substantially freed from carbon dioxide. The contaminated product acts as a nitrosamine-product that during reprocessing of solvent contaminated with nitrogen oxide or sulfur oxide. An independent claim is also included for a device for regenerating a nitrosamine contaminated product from a carbon dioxide capture system.
