Abstract:
The plugging of fluidized solids in long transfer lines is a particularly troublesome problem from an operational standpoint. Obstructions are cleared by closing off the transfer line at both ends, introducing an inert (non-deleterious) gas into the conduit at a few atmospheres pressure above the pressure at the conduit output, maintaining the gas pressure for a time to allow pressure equilization along the conduit, and thereafter opening the conduit outlet to permit the plugged solids to refluidize and then clear the line.
