Publication number: 20140345458Abstract: The present invention provides strategies for reducing the nitrosamine content of amine compositions that are contaminated with one or more nitrosamines. The present invention is based apart upon the appreciation that irradiating contaminated amine compositions with a suitable fluence of electromagnetic energy, such as ultraviolet energy, is able to selectively decompose the nitrosamine content relative to the amine content. This allows the amine content of the treated compositions to be preserved. As a consequence, the principles of the present invention are particularly useful for regenerating amine absorbents. Reducing the nitrosamine content so easily also facilitates disposal, further processing, or other desired handling of amine compositions.Type: ApplicationFiled: September 20, 2012Publication date: November 27, 2014Inventor: Eric J.
