MUMBAI, India, July 7 -- Intellectual Property India has published a patent application (202647077163 A) filed by Basell Polyolefine Gmbh on June 22, 2026, for Process For Preparing Ethylene Polymers In A Slurry Polymerization With An Interruption.
Inventors include Prang, Harald; and Kuehl, Reinhard.
The application for the patent was published on July 03, 2026, under issue no. 27/2026.
Abstract: A slurry polymerization process for the preparation of polyethylene in a polymerization reactor at a temperature from 40°C to 150°C and a pressure from 0.1 MPa to 20 MPa to obtain an ethylene-based polymer, wherein the polymerization occurs in a polymerization reactor at least in the presence of a catalyst, ethylene and diluent in a reactor slurry, wherein the process comprises a shut-down phase in which the at least one reactor inlet is closed, the reactor is cooled down to a predetermined temperature threshold, the agitator is stopped letting the reactor slurry settle down to the bottom of the internal reactor volume, the active cooling of the reactor and heat exchanger is stopped and the circulation loop pump is stopped.
