Polypropylene Plant Energy Analysis And Energy-saving Technology Research

In the light of the adjustment of industrial structure fo Yanchang prtroleum group and the urgent request of the shortage of the propylene resource, the paper investigate the reasons that causes high comsumption of propylene of polypropylene device from Yanan refinery 100kt/a polypropylene unit. The influence factors, such as the jam frequency of Z203, unstable operating conditions of PK301, unreasonable design of E301, poor cooling effect, big emission of propylene rusult from the opening or stopping of the device, high amount emission of desalted waterfrom electrolytic hydrogen system, flash lines is easy to cause the material hanging block, and the abnormal polymerization result from the tocicant of the raw material propylene were studied. Aitionally, the mesures for reducing propylene consumption for the factors were investigated. The results indicate that the optimization measures is confidently reduce thecosumption of propylene for the polypropylene device of Yanan refinery factroy form Yanchang prtroleum.In this study, reducing the unit consumption of propylene and energy consumption, reduce the processing costs, for the Yanan refinery chemical strategy and products from the refinery to the chemical type of high value-added transformation has the important practical significance. Design and operation optimization for other similar polypropylene device also has an important guiding significance and reference value.
