The present invention provides methods for removing particulate and a vapor phase contaminant from a gas stream comprising, in one embodiment, directing a gas stream comprising fly ash and a vapor phase contaminant into a particulate collection device, wherein the particulate collection device comprises an upstream collection section and a downstream collection section; removing at least a portion of the fly ash from the gas stream in the upstream collection section; injecting a sorbent into the particulate control device between the upstream collection section and the downstream collection section; adsorbing the vapor phase contaminant onto the sorbent to produce spent sorbent; and removing the spent sorbent from the gas stream in the upstream collection section. An apparatus is also provided for performing the methods.
