Embodiment Construction
[0080] see figure 1 with figure 2 , this propylene production unit includes:
[0081] A liquid phase reaction system 10 for liquid phase homopolymerization;
[0082] A pressure separation system 20 used for separation, liquid removal, discharge and sealing of polypropylene powder and propylene liquid;
[0083] A fluidized bed reaction system (or called a fluidized reaction system) for producing copolymerized polypropylene by completing the copolymerization reaction between polypropylene copolymer and other monomers30;
[0084] Steaming system 40 for polypropylene pre-drying;
[0085] A propylene recycling system 50 for the recovery and recycling of propylene and other monomers;
[0086] Polypropylene drying system 60;
[0087] Propylene supply system 70.
[0088] The working process is as follows:
[0089] The configured catalyst is injected into the liquid phase reactor (liquid phase bulk reactor) 12 through the catalyst inlet 11 in the liquid phase reaction system 10...
