Abstract

A method for facilitating reducing mercury in a fluid stream using a catalytic bed assembly including at least a first catalytic bed. The method includes receiving a flow of fluid including mercury at the catalytic bed assembly; injecting a flow of a compound including ammonia and a first mercury oxidizer upstream of the first catalytic bed; and oxidizing the mercury using the mercury oxidizer and the catalytic bed assembly.
