Abstract
The present invention discloses an apparatus and process for removing particulate material and mercury-containing compounds from a gas stream. The apparatus includes a particulate removal means to remove the particulate material and a mercury collection means to remove the mercury-containing compounds. The apparatus can selectively remove particulate material and mercury-containing compounds which may be disposed of separately. The mercury collection means is positioned downstream of the particulate removal means and includes a regenerable sorbent. The sorbent is regenerated by elevating the temperature of the sorbent to release the mercury-containing compounds from the sorbent.
