Abstract
The present invention discloses a process for removing undesired particles from a gas stream including the steps of contacting an additive containing nitrate and/or nitrite anions with the gas stream; collecting the undesired particles and additive on a collection surface to form an aggregate on the collection surface comprising the additive and undesired particles; and removing the agglomerate from the collection zone. The anions can be compounded with one or more of potassium, sodium, calcium, and aluminum. In a preferred composition, the anion(s) is/are compounded with potassium. The process may be applied to electrostatic precipitators to improve undesired particle collection efficiency.
