ABSTRACT:
A liquid--liquid separating hydrocyclone that utilizes gradual taper angles to reduce energy loss, helical precession, and velocity differentials and, thereby, increase the efficiency and capacity of the hydrocyclone. A separation portion of the hydrocyclone tapers to the underflow outlet orifice and no cylindrical portion is used at the underflow end. The hydrocyclone has either one or two frustoconical taper sections that have predetermined taper angles. The hydrocyclone cavity conforms to specified relationships that limit the taper and length to provide sufficient retention and to maintain the centrifugal force at the underflow end. The hydrocyclone includes inlets for introduction of a liquid mixture and separate outlets for the less dense liquid and the more dense liquid. An improved method of separating a less dense liquid from a more dense liquid is to functionally apply the above described hydrocyclone.
