Latest Patents

One of Hazelton's latest patents is related to phase separation processes. This innovative separation process allows a polymer-solvent solution to separate into phases of highly different composition, which remain in equilibrium over a broad temperature range. The addition of a phase-separating agent, which is near or above its supercritical conditions, leads to rapid disengagement into two distinct phases. Notably, the solvent-rich phase is significantly larger than the polymer-rich phase. This process can be conducted at relatively low temperatures, making it suitable for both polymerization and post-polymerization processes. The separation is achieved by adjusting the concentration of the phase-separation agent to or above a minimum effective concentration, causing the upper and lower critical solution temperature lines to merge. The phase-separating agents used are organic and inorganic compounds that exist as gases at standard atmospheric pressure and room temperature. Their gaseous nature allows for easy removal from the solvent phase for reuse.

Another significant patent by Hazelton is the autorefrigeration polymerization apparatus. This invention addresses the fouling of autorefrigeration polymerization systems caused by entrained particles in the vaporized solvent-diluent. By returning the recycled solvent-diluent into the reaction zone through nozzles that create a fine spray of droplets, the system effectively removes major amounts of entrained particles down to 5 microns in size. The solvent-diluent can be either an inert material or unreacted alpha-olefin, such as propylene.
