Abstract: A few methods for shaping and assembling a highly efficient cyclone separator for the removal of entrained solids from gases comprises basically, among other steps, the novel steps of:(1) attaching a solids-free-gas outlet (74) having an area (O) to the upper portion of the separator housing shaped for receiving solids-free-gas at a velocity in the range of 52 feet per second to 200 feet per second,(2) forming the solids-free-gas outlet area (O) proportional to the separator inlet area (I) in the range of substantially O/I=0.4/1 to 1.0/1.0, and(3) forming the distance (L) from the gas outlet (74) to the solids outlet (70) proportional to the diameter (D) of the cyclone separator cylindrical portion (56) in an amount of L/D=4.49-1.09 (O/I) for providing maximum efficiency with minimum erosion of both the cyclone separator internal housing wall surface and of the separated solids. L/D is about 4.0.

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.

Abstract: A cyclone separator for the removal of entrained solids from gases, the cyclone separator having a barrel portion and a conical portion which cooperatively define a separation chamber, a gas inlet in open communication with the portion of the separation chamber defined by the barrel portion, a gas outlet tube extending centrally, upwardly from the barrel portion, a solids discharge outlet located at the lower end of the conical section, a solids discharge dipleg conduit in open communication with the solids outlet, the geometric parameters of the separator providing high efficiency with minimal erosion.
