摘要: 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.

摘要: A mercury monitoring device that continuously monitors the total mercury concentration in a gas. The device uses the same chamber for converting speciated mercury into elemental mercury and for measurement of the mercury in the chamber by radiation absorption techniques. The interior of the chamber is resistant to the absorption of speciated and elemental mercury at the operating temperature of the chamber.

摘要: Cement waste product (CWP), such as recovered from kilns utilized in cement production, is used for scrubbing of sulfur oxide-containing industrial offgases. The CWP is preconditioned with liquid water prior to employing it as a scrubbing medium. Preconditioning involves addition of sufficient water to the essentially anhydrous CWP to achieve essentially total rehydration of the rehydratable calcium compounds contained in the CWP, for example, aluminates, oxide and sulfates. The preconditioned CWP is dried and used as a highly efficient scrubbing medium for sulfur oxides.
