This paper illustrates the potential for separation of nm magnetic particles from viscous flows with a brief discussion of a novel magnetic method for breaking tight emulsions(U.S.Patent No.5,868,939)which was the forerunner of a new primary separator,the Magnetic Micro-Particle Separator,(MM-PS,patent pending).The remainder of the paper will focus on the MM-PS which was designed for high throughput isothermal and isobaric separation of nm iron catalyst particles from Fischer-Tropsch wax at 260deg C.Using magnetic fields up to 2,000 gauss,F-T wax with 0.3- 0.5 wt% solids was produced from 25 wt% solids F-T slurries at product rates up to 230 kg/min/m~2.The upper limit to the filtration rate is unknown at this time.The test flow sheet is given and preliminary results of a scale-up of 75:1 are presented.
