polyvinyl chloride (PVC). The vinyl chloride production is almost exclusively realised through the so-called balanced process, where ethylene, chlorine and oxygen are con-verted into the product, involving 1,2-dichloroethane as intermediate. In this thesis a complete ow-sheet representing the whole plant is developed by using the gPROMSR
Process flow diagram for the manufacture of vinyl chloride. Figure 2.2 shows the PFD for the manufacture of vinyl chloride using chlorine and ethylene as raw materials. Vinyl chloride is an important product since it is used in the manufacture of polyvinyl chloride (PVC). This manufacturing process involves three major steps.
We created models of the process units so that they both produced 5250 kg/hr of vinyl chloride, with nearly identical purities (by mass) of 98% for oxychlorination and 97.6% for direct ...

POLYVINYL CHLORIDE (PVC) PLANT. PVC Plant consists of 'Batch Processing' 4 lines having the same capacity. The production is licensed by "SOLVAY". PVC is produced by polymerization of 'Vinyl Chloride Monomer' accompanied by catalyst at a certain temperature and pressure in aqueous medium.
Process Overview •Typical Vinyl Chloride monomer production plant •Comprised of five main sections •Direct chlorination of ethlyene to form EDC •Oxychlorination section: ethylene reacted with recycled HCl and O 2 •Purification of EDC (Cracking, Quenching, etc.) •Thermal cracking of EDC to form VCM and HCl •Purification of VCM •Our Focus: EDC Purification and VCM Purification
A large number of chemical species are present in the vinyl chloride plant. Generally most of the compounds are non-ideal and somewhat polar. The modified Suave-Redlich Kwong (SRK) equation of state was used to simulate the vinyl chloride plant. This equation of state handles polar-nonpolar systems well (17). It is recommended for

The process flow diagram for Aspen Plus simulation of the vinyl chloride monomer manufacturing plant is shown in Figure 4.23. The flowsheet has been developed based on the VCM production technology reported in a book by Seider et al. (1998).

Vinyl Chloride, the process also generates hydrogen chloride as by-product. The report examines one-time costs associated with the construction of a plant and the continuing costs associated with the daily operation of such a plant. The analysis assumes a United States-based plant capable of producing 500 kt of Vinyl Chloride per year and includes:
