The discovery and exploitation of shale gas in North America is providing a boost to the domestic petrochemical industry. In particular, commodity petrochemicals such as polyvinyl chloride (PVC) are experiencing a strong resurgence in North America. PVC is made from vinyl chloride monomer (VCM), which is derived from ethylene dichloride (EDC), which, in turn, is produced from ethylene. At the heart of the VCM process is the EDC cracking furnace where EDC is thermally cracked to vinyl chloride and hydrogen chloride. This furnace is a highly specialized unit that must be carefully designed to achieve the necessary residence time at a specific temperature and pressure to achieve the desired pr
