EDC Pyrolysis

With over 45 years of proven installations, Selas Fluid is acknowledged as the leading supplier of Ethylene Dichloride (EDC) cracking furnaces. We have equipment installations and experience utilizing virtually every major vinyl chloride monomer (VCM) processor including, but not limited to:
  • Oxy Vinyls LP
  • Ineos Vinyls (formerly EVC/Stauffer)
  • Solvay
  • PPG
  • Dow
  • Shell
  • ICI
  • Mitsui

Utilization of our unique offset convection section with a dynamic radiant tube support system offers certain design features that improve performance, operation, maintenance, tube life and runtime. We have over 80 EDC furnaces installed worldwide in VCM plants with capacities to 225 kta.

EDC Pyrolysis - Computer Modeling Coupled with Actual Experience

EDC Fire Box
EDC Fire Box


 The most important component of an EDC cracker is the pyrolysis coil design. At Selas Fluid, radiant coil geometry is determined using our proprietary, technically advanced computer model of the reaction kinetics occuring within the coil. This program establishes the optimum furnace design with respect to temperature, pressure drop and residence time as well as predicted run time from the buildup of Methyl Chloride and Butadiene. Additionally, film cracking is minimized in our furnace design to reduce byproduct formation and resultant coke/carbon laydown.

Whether the fuels are liquid or gas, burners are sized and arranged to heat the process fluid under accurately controlled conditions of temperature and heat flux resulting in a furnace with the best possible onstream characteristics in terms of conversion rate, minimal byproduct formation and low overall operating and maintenance costs.
