Abstract
A method for processing a flowable nonaqueous, high viscosity dispersion which includes a product, where the product is a particulate material having a particle size between about 1.0 microns to about 200 microns, is disclosed. The flowable dispersion has a viscosity from about 10 cps to about 500 cps at 140.degree. F. The method comprises cross flow filtering the dispersion through a porous nonmetallic inorganic filter having a pore size from about 0.5 to about 10 microns. The cross flow rate is in the range of from about 3.0 to about 9.0 feet/second (1 to 3 ml/sec) at least about 120.degree. F. and preferably there is at least one backflush at a rate of about 2 to about 5 seconds for every 3 to about 5 minutes of cross flow filtration.
