Appl. No.:

09/660128

Inventors:

Robert Elmer Running - Wrightsville Beach NC
Richard Anderson McBraye - Wilmington NC
Gregory Nash Latham - Currie NC

Assignee:

Occidental Chemical Corporation - Dallas TX

International Classification:

B01F 706

US Classification:

366251, 366270, 366307, 105358

Abstract:

Disclosed is an agitator assembly which comprises an agitator and means for mounting the agitator assembly on top of a tank. The agitator comprises a shaft, a propeller fixed to one end of the shaft, and means for rotating the shaft to provide an axial discharge from the propeller of at least 4. 0 m/sec with a flow equivalent of at least 0. 2 tank volumes/minute. The agitator is mounted on top of the tank so that the shaft enters the tank at an angle a to the longitudinal axis of the tank of between about 30 and about 60 degrees and at an angle to the transverse vertical axis of the tank of less than about 50 degrees. Also disclosed is a method of shipping solids that are soluble in a solvent. The solids are placed in a tank on which the agitator assembly has been mounted. The quantity of solids placed in the tank exceeds the amount that will dissolve when the tank is filled with the solvent.
