ABSTRACT:
A method of removing gaseous selenium from a flue gas is disclosed. The method includes injecting an effective amount of ammonia into the flue gas to produce a solid selenium reaction product. The solid selenium reaction product is removed from the flue gas by undergoing deposition in a filter assembly. The filter assembly may then be cleaned through conventional methods.
