Instruction manual:
Polypropylene is a generic synthetic resin ,which is polymerizated by propylene monomer .As a polymer plastic, in the modern chemical production it occupies an important position and was one of the five major engineering plastics.
Polypropylene is the fastest developing material in variety of hydrocarbon materials .The key reason is the catalyst’s rapid development. This design introduced polypropylene’s development with the development of catalyst.
The design is based on the S-PP technology and set for 90,000 tons of annual output .Then proceed to the material balance 、 energy balance and equipment selection, Finally reached a more complete design specification.
Another, Because of its rich resource, low price, easy to process takes shape, fine productoverall performance,therefore it is widely applied to chemical,the chemical fiber, the light industry, the electrical appliances, the building, the packing, agricultural, the national defense, thetransportation, the civil plastic product and so on. In the polyolefine resin,it is only inferior after the PVC、PE the third general plastic.
Along with the chemical industry fast development, the chemical product already the omnipresent there is no place did not have. Therefore the chemical design duty is more and more heavy. First, in the chemical production, through transporting chemical industry design aspect knowledge and the method, may realize to the chemical factory (workshop) rebuilding and extension, carries on the productivity to the unit operation equipment or the entire installment to demarcate with the technology economic indicator evaluates; carries on the appraisal to the technical process; discovers the weak link and unreasonable phenomenon as well as excavation productive potential and so on. Second, in scientific research, since childhood experimental to experimental enlargement, down to the investment industrial production, all cannot leave the design. Looked from the modern times photochemistry industrial development process that, the research holds the important status day by day. But if we want cause the scientific research achievement to transform the productive forces, namely realizing industrialization, We must carry on the scientific research and design in close integration with new development work and so on craft, new product as well as new equipment. Third, in the capital construction, design is the capital construction most important link, is the ready-made construction basis. From single equipment to complete set installment, from a miniaturized factory (workshop) to large-scale petroleum chemical industry enterprise, they all must first finish the engineering design before construction. If we want to complete a good quality and advanced level chemical industry installment, the important precondition is must have a high level and high grade design. Enhanceing the design’s quality and speed is the crucial promoter action to the capital construction enterprise development.
This design content is about 90000 tons/year polypropylene production technology design, design including process flow design, material calculation, energy calculation, equipment selection, safe environmental protection and economic technology evaluation. In this paper a detailed calculation out of raw materials, product of dosage units unit output, is by the heat transfer area selected for the various kinds of equipment technology, according to the selection process design out of the process flow diagram and production workshop pattern, and in the last wrote the feasibility study report, business planning books and user manuals.
This design has referred to below the national standard and the stipulation.
