ABSTRACT:
A method for removing mercury from a gas stream. In the method, sorbent is injected into the gas stream. Water is dispersed into the gas stream to create a cooled gas stream. The cooled gas stream is allowed to dwell with the sorbent in a chamber to remove mercury from the cooled gas stream. The cooled gas stream is passed through an electrostatic precipitator located above the chamber which collects water and recycles the collected water back into the chamber for cooling the gas stream in the chamber. An apparatus for removing mercury from a gas stream is also provided.
