UNIPOL PP Process Technology Used in Coal-to-Olefins Plant in China      

The 300 000 t/a polypropylene facility came online in early August, using UNIPOL TM Polypropylene (PP) Technology from Dow Basic Plastics Licensing and Catalysts, a business group of The Dow Chemical Company (Dow).
    UNIPOLTM PP Process Technology is an all gas-phase process for producing the broadest range of polypropylene resins. Its simple design is both consistent in terms of product quality and energy efficient, requiring no equipment for handling, separating or recycling solvents. The system's fluidized-bed reactors and high performance SHAC TM Catalyst systems give manufacturers the flexibility to produce homopolymers, random copolymers and impact copolymers.
   The integrated coal-based mega plant is built by China Shenhua Coal to Liquid and Chemical Baotou Coal Chemical Company, under Shenhua Group, which is the first to manufacture PP made from coal-generated olefins. According to the company, its gasification technology converts coal into a synthesis gas (or syngas); syngas is used to produce methanol, which is transformed into olefins - a building block for producing polypropylene.
