The experience of CONSER in ethylene plant design and revamping extends over more than 30 years.
Design features which have been incorporated in existing plants include the following:

• Optimum recovery of the heat available from the pyrolysis furnace effluent stream
  
  
• Addition of low level waste heat recovery facilities
  
  
• Improved integration of the heat requirements in the process with the heat available in the quench system
  
  
• Reduction of pressure drop at the interstages of the compression system
  
  
• Increase of the number of the distillate and condensate strippers to reduce the
  recycle to the compressor system
  
  
• Improved demethanized feed system by multifeed chilling and prefractionation to decrease refrigeration duties
  
  
• Incorporation of turboexpander - recompressor in the demethanizer overhead to reduce the cryogenic refrigeration load
  
  
• Reduce the consumption of energy in the deethanizer by increasing the number of trays and using inter-reboiler
  
  
• Increase the efficiency of the ethylene fractionation tower employing external refrigeration circuits for reboiling and condensing
  
  
• Improved selective hydrogenation systems
  
  
• Improved integration of the process units with the utilities systems
  
  
• Improved valorization of the co-products as polymer grade propylene, C4 fractions, pyrolysis gasoline, aromatics, etc..
