Is PVC a Petroleum Product?
What is PVC?
PVC, or polyvinyl chloride, is a widely used plastic known for its versatility and durability. It is made through a complex chemical process that involves the polymerization of vinyl chloride monomers (VCM). PVC can be found in a vast array of products, from pipes and fittings in the construction industry to various consumer goods.
The Production Process of PVC
Role of Petroleum in PVC Production
Most commonly, PVC production starts with ethylene, which is a product of the oil & gas industry. Ethylene is combined with chlorine to produce an intermediate chemical called EDC (ethylene dichloride or 1,2 - dichloroethane). The chlorine is often derived from industrial - grade salt through electrolysis. After that, EDC is transformed into vinyl chloride monomer (VCM) through thermal cracking. Finally, VCM undergoes polymerization to form PVC. Since ethylene, a crucial starting material, comes from petroleum or natural gas, PVC can be considered a petrochemical product. However, it's worth noting that PVC can also be produced from other hydrocarbons like coal or derivatives of plants such as sugar cane, though this is not the prevalent method in Europe.
Steps in Detail
- Extracting Ethylene from Petroleum: Ethylene, a natural gas derivative supplied by the petrochemical industry, is captured during a process called thermal cracking. Liquid petroleum is heated in steam furnaces and put under extreme pressure. This changes the molecular weight of the chemicals in the petroleum feedstock, allowing ethylene to be identified, segmented, and captured. It is then cooled back down to a liquid state.
- Producing Chlorine: Chlorine, which is found in salt extracted from sea water, gains an additional electron during electrolysis. By sending a strong electric current through a salt - water solution, strong enough to change its molecular structure, chlorine is separated and then extracted from the mixture.
- Synthesis of EDC and VCM: When ethylene and chlorine react, ethylene dichloride (EDC) is created. This EDC then passes through another thermal cracking process, which produces vinyl chloride monomer (VCM).
- Polymerization to PVC: VCM is sent through a catalyst - containing reactor where polymerization occurs. Chemicals cause the VCM molecules to react until they link together, creating PVC resin.
