Abstract
The disclosure provides methods and systems for decreasing nitrosamine content, e.g., in the context of non-aqueous solvent systems. It includes a method including receiving a non-aqueous solvent system and contacting the non-aqueous solvent system with a composition including one or more alkoxides to give a treated solvent system having a nitrosamine content that is lower than the starting nitrosamine content. Similarly, it includes a system including a first unit configured to remove undesirable components from a gas stream; a second unit holding a composition including one or more alkoxides, and a conduit to connect these units.
