Abstract
Provided herein is a first fluid dispersed in a second fluid to form an emulsion of micro-droplets having an average droplet size and having a droplet size distribution around the average droplet size and below a maximum droplet size. The 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. The 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 the average particle size and the maximum particle size. A filtrate of the micro-filter comprises a majority of the micro-spheres that is substantially void of micro-spheres having a particle size exceeding the maximum allowable particle size.
