Abstract: Fire and explosion hazards in the production of polypropylene mainly depend on the hazard characteristics of the polymerization process itself and the dangers of the raw materials that are used, such as the flammability and explosion of propylene, hydrogen and catalysts, as well as the electrostatic accumulation of polypropylene powder and the risk of dust explosion. The accident cases of polypropylene plants at home and abroad are enumerated. Taking the 30t/a polypropylene plant of Lanzhou Petrochemical Company as an example, fire and explosion hazards of the plant are discussed from the aspects of process safety, dangerous raw materials and so forth.

Key words: polypropylene, hazard factors, fire explosion
