A fluidized-bed reactor for the oxychlorination of ethylene, oxygen and HCL,
comprises
a heat exchanger, having tube packets in the fluidized-bed for releasing the heat
evolved from exothermic reaction to a heat-transfer medium in the tube packets,
in particular to water/steam. The tube packets come into contact with water via
a ring pipe and the steam being removed via a ring pipe to provide an economical
solution with which expensive drilled passages are avoided, the calculation for
ring pipes is facilitated and a large number of wall passages is dispensed with.
This is achieved by the ring pipe being mounted as a collector or chamber directly
on the reactor wall.
