Abstract
A method for the removal of entrained solids from gases in a cyclone separator having a dipleg attached to the bottom thereof comprises the basic steps of, (1) injecting the gases with the entrained solids in an inlet (54) of cyclone separator in the range of substantially 52 feet per second (16 m/s) to 80 feet per second (24 m/s), (2) spinning the injected gases with the entrained solids around and down the cyclone separator to the inlet (70) of the dipleg (34) by a vertical distance (L) below the gas outlet (74) proportional to the diameter (D) of the top of the separator by an amount of L/D=4.49-1.09 (O/I) or about 4, and (3) ejecting the solids-free-gases through a gas outlet (74) in the range of substantially 52 feet per second (16 m/s) to 200 feet per second (61 m/s) having an area (O) in proportion to the area (I) of the separator inlet (54) in the range of substantially O/I=0.4/1 to 1/1, for providing a maximum efficiency with minimum erosion of both the cyclone separator internal wall surface and of the separated solids.
