For example, a fabric filter may be coupled with sorbent injection systems for collection of both gaseous and solid pollutants. Sorbent introduced up-stream of the fabric filter is deposited over the entire surface of the filter bags. Flue gas flowing through the sorbent-coated filter bags provides intimate pollutant-to-sorbent contact, thereby ...
