Clean Production Of Polypropylene Device

Polypropylene resin is one of the fastest growing varieties of synthetic resin, with the rapid development of polymerization and catalyst for propylene, polypropylene, grade varieties increased, expanding the scope of application, polypropylene has become a kind of synthetic materials is very important.Clean production is an environmental policy popularized in our country in recent years, this thesis, through the concept of cleaner production in accordance with the production process of polypropylene, reduce the fine powder and energy saving as the key research, thus minimizing the pollution of the environment, in order to achieve the objectives of environmental protection. It is instructive to the actual production of polypropylene plant.1first introduces the development history of production technology and catalyst in polypropylene, put forward existing problems in the production of polypropylene, polypropylene production from the resulting in lower consumption of fine powder and two energy saving research and solve problems.2from the Ji’nan branch of Sinopec polypropylene unit of the device is introduced, using the domestic Spheripol technology, used in the process is in a loop reactor with high efficiency catalyst polymerization method for producing polypropylene liquid propylene. The main production of the device (row) and node is powder scrubber process wastewater, waste produced by the reaction of condensed oil, waste powder granule.3describes the harm in the production of polypropylene unit fine powder production, causes of powder of the plant are analysed, put forward to reduce the corresponding countermeasures continued disputes, and the effects of the test.4presents the energy consumption in the process of producing polypropylene device part, starting from several reduced circulating water consumption, electricity consumption, steam consumption, high energy consumption, solving the device, and the benefit analysis. 5to further reduce energy consumption improvement measures and schemes, combined with economic analysis, obtained apparent effect from the environmental benefits, economic benefits, social benefits and other aspects, the energy saving, energy, pollution reduction, waste utilization organically, throughout the whole process of production and operation of. The device into the track of healthy development of energy saving, pollution reduction efficiency, will obtain good economic and social effect.
