The Preliminary Design about the Synthesis Construction Section

of Vinyl Chloride of PVC 50000 tons per year

Speciality: Chemical engineering & technology Author: Su Lin Supervisor: Zeng Wennan

Abstract:This graducation design is a primary designed about synthesis construction section of vinyl chloride of PVC 50000 tons every year.According to the Zhuzhou chemical industry group scene practice pertinent dates and related dates,the design was completed with the calculation of the balance of material and heat quantity.During the sign,the instruction booklet and three diagrams have been worked out．

The main contention of the instruction booklet can be briefly illustrated as follows:1.The development history of producing PVC &VC and its trendency.2.The production way to produce VC.3.The calculation of the balance of material and calculation of heat quantity.4.The design and choice about the main equipments.5.The design and choice about the main pipelines.6.The disposal of three wastes processing security and fire protection technology.

There are three diagrams as follows:1.The technique flow chart with controlled point.2.The factory floor-plan diagram.3.The main equipment installing picture.

Key words:synthesis、PVC、VC、technological、design.
