Abstract

A method and system of for introducing an active material to a chemical process in which a processing element including a passive component and an active element is installed within the system and exposed to a chemical process performed within the system. As the chemical process proceeds, the passive component erodes and thereby exposes the active component embedded therein. The introduction of the active component to the chemical process alters the chemical process.
