  • Cleaning and separation in conduits
    Patent number: 6916383
    Abstract: A coherent body (B) of wet crushed ice is pumped along a pipe (5). The crushed ice body can be used as a means of cleaning the pipe wall, as a means of driving a product liquid out of the pipe for recovery, or as a barrier for preventing mixing of two different bodies of liquid (1,2) in the pipe to either side of it. Being coherent but flowable and non-tensile, the mass of crushed ice can negotiate internal constrictions, obstructions and junctions of the pipe readily, unlike conventional solid or gelled pigs.
