CB&I's Novolen® technology licenses the gas-phase polypropylene process worldwide on the basis of Ziegler-Natta and metallocene catalysts for the production of a full range of polypropylene resins. This reliable and versatile process produces products meeting the requirements of the most demanding applications, while maintaining a strong focus on health, safety and environmental issues. The gas-phase process features lower total installation costs (TIC) and is very competitive in cash production costs.
CB&I’s on-purpose technologies for the production of polymer grade propylene, such as CATOFIN® dehydrogenation and Olefins Conversions Technology (OCT), allows licensors all over the world to benefit from the synergies provided when combining those in-house technologies with Novolen’s polypropylene technology.
The Novolen technology gas-phase process utilizes one or two identical vertical gas-phase stirred bed reactors. Homopolymers and random copolymers can be manufactured either in a single reactor or in a reactor cascade with two reactors, depending on the required capacity and product range. Alternatively, two reactors can be operated in parallel to achieve higher capacities for a single train plant and to produce bimodal resins. A cascade reactor configuration is required for the production of impact copolymers, whereas in the first reactor a propylene homopolymer (or random copolymer) matrix is polymerized and in the second reactor the ethylene-propylene rubber (EPR) is produced. Independent from the configuration chosen, all reactors are identical in design, size and material.
Our advanced Novolen VRC® reactors allow for choosing between a parallel and cascade reactor configuration without any downtime. This concept provides you with ultimate flexibility.
