Abstract

A first fluid is dispersed in a second fluid to form an emulsion of micro-droplets having an average droplet size and having a droplet size distribution around said average droplet size and below a maximum droplet size. Said micro-droplets will lose their solvent to transform to micro-spheres exhibiting a particle size distribution around an average particle size and substantially below a maximum allowable particle size. Said micro-spheres are subjected to a micro-filter having a relatively narrow pore size distribution around an average pore size, which average pore size is between said average particle size and said maximum particle size. A filtrate of said micro-filter comprises a majority of said micro-spheres that is substantially void of micro-spheres having a particle size exceeding the maximum allowable particle size.
