An all gas-phase technology based on a fluidized bed reactor system, UNIPOL® PP process is designed to have fewer moving parts and less equipment than any competing technology. The simple, reliable design of UNIPOL® PP process and related product technology, coupled with SHAC® catalyst systems and the new CONSISTA® catalyst systems, offers another significant economic benefit – the ability to operate the plant above nameplate capacity. The core UNIPOL® PP process facility has the smallest footprint in the industry, about 60 meters by 65 meters. This includes the following operations: Purification Reaction Purging Vent Recovery Additive Addition Pelleting SIMPLE, YET STATE-OF-THE-ART UNIPOL® PP process and related product technology is state-of-the-art. At the same time, it is mechanically simple and easy to operate. A minimal amount of major equipment is required. There are only three or four pieces of major rotating equipment depending on your configuration. A single reactor is used to produce homopolymers and random copolymers. A second reactor in series with the first will allow production of impact copolymers. The simplicity of the homopolymer/random copolymer systems is also mirrored in the impact copolymer state. It uses the same gas-phase fluidized bed process with a slightly smaller reactor.
