Activity Description
Using the SPG-HT continuous polypropylene process, which combines slurry polymerization and horizontal reactor gas-phase polymerization, the production process includes propylene purification (removal of light components, desulfurization, dehydration, and arsenic removal), pre-polymerization, polymerization reaction, gas-solid separation, propylene recovery, steaming, and drying.
Process Description
Polypropylene (PP) resin is one of the five major general-purpose thermoplastic synthetic resins. It appears as a white powder or granules and dissolves in solvents such as dimethylformamide or thiocyanates. Polypropylene is a non-toxic, odorless, tasteless, white, highly crystalline polymer and is currently one of the lightest varieties among all plastics. It can be used in fields such as electronics and electrical appliances, automotive, construction materials, medical devices, and packaging.

Technology comment
The SPG-HT continuous polypropylene process is adopted, with the reaction section consisting of liquid-phase pre-polymerization, liquid-phase bulk polymerization, and gas-phase polymerization. Liquid-phase pre-polymerization and liquid-phase bulk polymerization are both carried out in vertical reactors, while gas-phase polymerization takes place in a horizontal reactor; all reactors are equipped with stirrers. The powder post-treatment system employs a steaming and drying process, which efficiently removes hydrocarbons and oligomers from the powder, enabling the production of high-quality polypropylene products with low VOC content and low odor.
