摘要：

To reduce greenhouse gas emissions from fossil fuel power plants, post combustion CO2 capture with amine-based solvent is the most mature technology. Ethanolamine (MEA), the benchmark amine, is the most studied amine but some degradation products are still unknown and for an environmental acceptance, it is important to identify them. In this work eleven amides and nitrogenous heterocycles were identified in a pilot plant liquid sample. Among them seven molecules were never reported in literature. Different analytical methods were developed especially HS-SPME coupled to GC/MS. Mechanisms of formation were proposed for each molecule and were validated in most cases. (C) 2014 Elsevier Ltd.
