Abstract
A filter cleaning process for filters for separating particulates from a hot gas stream using hollow, tubular filter elements. Blowback and hot purge gas systems provide for cleaning of the filter elements and maintenance of the blowback system clear of the solids or condensation products that might form during separation. The process is especially useful in filtering solids from a hot, corrosive gaseous stream, such as a zirconium tetrachloride process gaseous stream, where the gas stream contains gaseous constituents that are subject to condensation directly to a solid during separation of the particulates and prior to discharge from the filtering apparatus.
