The VCM Production Process Overview. Producing sales quality PVC from raw materials involves several steps. Initially, ethylene dichloride (EDC) must be produced from the feed stocks of ethylene and chlorine. The EDC is then thermally cracked to produce vinyl chloride (VCM), which is the chemical precursor to the PVC polymer.
PVC is the second largest commodity plastic after polyethylene with world production currently over 18 million tonnes a year. The chemical process for making PVC involves three steps: first, production of the monomer, vinyl chloride; then the linking of these monomer units in a polymerisation process; and finally the blending of the polymer ...
The first step in the production of plastic objects is extracting the raw material that is derived from natural gas or refined crude oil. The drilling is done by heavy machinery to take out raw material from the underground. The collected raw material is sent through the pipes for the refinery process. To make pellets of pure plastic, heating ...
PLASTIC EXTRUSION: Plastics extrusion is a continuous high-volume manufacturing process, in which raw plastic is melted and formed into a continuous profile. This process starts by feeding plastic material (pellets, granules, flakes or powders) from a hopper into the barrel of the extruder. The material is gradually melted.

Many CHCs are created during the production of PVC; this is a growing concern. Therefore, VCM needs to be produced in a way that will minimize or totally eliminate the release of CHCs into the environment. The goal of this project is to design an environmentally friendly, safe, and economically profitable vinyl chloride production plant.
A Process Flow Diagram - PFD - (or System Flow Diagram - SFD) shows the relations between major components in a system. PFD also tabulate process design values for components in different operating modes, typical minimum, normal and maximum. A PFD does not show minor components, piping systems, piping ratings and designations.
major precursor for PVC production. It is a colorless liquid with a chloroform-like odor. Ethylene dichloride is also used generally as an intermediate for other organic chemical compounds, and as a solvent. Ethylene dichloride is produced through the iron(III) chloride catalyzed reaction of ethene (ethylene) and chlorine. H 2 C=CH 2 + Cl 2

Jan 06, 2011· Polyvinyl Chloride (PVC) Production and Manufacturing Process. A number of PVC processes are employed according to the end application, but polymerisation is normally performed at 40-70oC with the VCM in a liquid state under pressure in a batch reactor. All routes employ free radical initiators which are either soluble in the monomer or in the ...
The increasing of polyvinyl chloride (PVC) gives impact to increase of production of vinyl chloride monomer (VCM). VCM is produced from the exothermic reaction. The raw materials of production VCM is ethylene, chlorine and oxygen where all the material is pure. As an exothermic reaction, it will give the biggest problem that is runaway

sunlight. The earliest patents for PVC production were taken out in the USA in 1912 and pilot plants producing PVC began in Germany and the USA in the early 1930's. Early PVC processing technology was based on established rubber moulding processes and the products that could be manufactured were limited to those using heavily plasticised polymer.

PVC currently ... polystyrene, ethylene glycol, or polyvinyl chloride (PVC). Ethylene demand is generally demand and classified as fitness-to-standard, based upon the existing characteristics ...
The production process, or manufacturing process, consists of a few key components or sub-processes from production planning through quality assurance and inspection of final products. Manufacturing process flow charts, or workflows, can be applied to the manufacturing process to reduce lead times, increase machine utilization and optimize first pass yields.
