<p>PCT No. PCT/US97/00884 Sec. 371 Date Jul. 30, 1998 Sec. 102(e) Date Jul. 30, 1998 PCT Filed Jan. 22, 1997 PCT Pub. No. WO97/27924 PCT Pub. Date Aug. 7, 1997This invention relates to a process for centrifugal separation of polyamide and polypropylene materials contained in a liquid slurry. The polypropylene material has a specific gravity which is less than the specific gravity of the liquid carrier and the polyamide material has a specific gravity which is greater than the specific gravity of the liquid carrier. A gas, preferably air, is injected into the slurry prior to feeding the slurry to a hydrocyclone.</p> |
