Definitions

  • the reactor effluent of the cracking furnaces is quenched in the shell and tube heat exchanger from 750 ⁇ 900°C to 350 ⁇ 560°C (Kirk-Othmer I.c., page 407, table 5) to prevent that after leaving the cracker furnace, in said effluent still reactions take -place under adiabatic conditions, which would affect adversely the yield of alkenes, and simultaneously steam with a pressure of 105-125 bara (bar absolute) is generated.
  • the temperature of the quenched effluent coming from the TLX (A) in the beginning of the test was 420°C and the temperature of the quenched effluent coming from TLX (B) was 450°C.
  • TLX (curve A) the temperature of the effluent coming from the TLX, increased to 500°C in about 5 days and during the rest of the test the temperature gradually further increased, until after 26 days the maximum allowed temperature of 560°C was obtained.
  • Coating the internal surface of the heat exchanger tubes of TLX (B) was carried out by spraying a mixture of 12% by weight of aluminium powder with a particle size of ⁇ 2 pm, 48% by weight of a silicone resin comprising methyl groups and phenyl groups, and 40% by weight of toluene into the tube, draining the excess and heating the remaining layer for 2 hours at 300°C, thus vaporizing the toluene and reticulating the resin, repeating this processing once, and finally repeating the treatment once with a mixture of 10% by weight of aluminium powder with a particle size of ⁇ 2 p m, 40% by weight of the same silicone resin and 50% by weight of toluene.
  • Example I A similar test was carried out as in Example I, wherein now a TLX (D) was used having heat exchanger tubes the internal surface of which was coated with a polymeric layer, formed by mixing the oily fraction obtained when quenching the effluent from the cracking reactor (ethylene quench oil) with 1.5% of benzoyl peroxide and introducing said mixture into the heat exchanger tubes, draining off the excess and externally heating the tubes at 400°C.
  • a TLX (D) having heat exchanger tubes the internal surface of which was coated with a polymeric layer, formed by mixing the oily fraction obtained when quenching the effluent from the cracking reactor (ethylene quench oil) with 1.5% of benzoyl peroxide and introducing said mixture into the heat exchanger tubes, draining off the excess and externally heating the tubes at 400°C.
