Material selection for the distillation and purification of dichloroethane produced by ethylene oxychlorination (four-column process)
Thread Content
Hello, everyone! I would like to ask what materials would be suitable for use in the first tower (dehydration tower) and the second tower (light ends removal tower) of the distillation process (four-tower process) used to produce dichloroethane via ethylene oxychlorination What about the reboilers and condensers of each tower? Thank you, senior!
The material for the tower can generally be carbon steel; carbon steel should also be used for the tray plates, although stainless steel is an even better option (though it will increase the cost)； For reboilers and condensers, copper-nickel is recommended due to its corrosion resistance.
