Abstract: Novolen gas-phase process is widely used in the production of polypropylene products, which can achieve full range of polypropylene product coverage. During the polypropylene production process, the ratio of various materials, reactor temperature, catalyst flow rate, etc. have a great impact on the quality of the product. Due to the lack of a quality prediction model with strong generalization and interpretation, the quality of polypropylene products is difficult to control. A polypropylene quality prediction model is built by designing a mechanism-based AI hybrid technology, taking material ratio, reactor temperature, catalyst flow rate, etc. as mechanism inputs, and screening those with high correlation with polypropylene quality as noise inputs outside the mechanism. Based on historical data fitting, a polypropylene quality prediction model with strong generalization and good interpretation is achieved. The polypropylene quality prediction model combines advanced process control theory to build an automated, safe and stable advanced process system.
