ABSTRACT:
A process for filtering fine particulates from a stream of hot gas wherein the particulates vary in size between about 0.15 and 250 microns includes the steps of removing a majority of the larger size particles from the gas stream, while leaving a majority of the smaller particles in the stream, then introducing into the gas stream particulates having an average size greater than the smaller size particulates, and thereafter passing the gas stream through a porous filter medium having a pore size exceeding the size of the smaller size particulates.
