Latest Patents

Robertson holds a patent for an olefin polymerization process. This patent discloses a method for reducing fouling in an apparatus and process for separating polyolefin from a slurry in a slurry polymerization reactor system. The process involves contacting a catalyst composition and α-olefin monomers in a reactor at a pressure of at least 2000 kPa to form a polyolefin reaction mixture. The mixture is then transferred to a high-pressure separator, where the pressure ranges from 200 to 2500 kPa. Additionally, the polyolefin reaction mixture is treated with an organic amine before entering the high-pressure separator. This innovative approach enhances the efficiency of polyolefin separation.
