ABSTRACT:
The fouling of autorefrigeration polymerization systems because of entrained particles in the vaporized solvent-diluent is substantially reduced by returning the recycle solvent-diluent into the reaction zone through nozzles which provide a solvent-diluent spray of an average droplet size of less than 1000 microns, preferably between about 225 and 300 micron average particle size, which spray removes major amounts of entrained particles down to 5 microns in size. The solvent diluent may be an inert material or unreacted alpha-olefin, such as propylene.
