Frigen Cracking Furnaces
Various different hydrocarbons containing chlorine and fluorine are heated and cracked with or without the addition of water vapour in a cracking coil at temperatures between 680 and 800°C and at low overpressures. During the reaction tetrafluoroethylene is created as a raw material for polymer production.
