Leakproofness inspection of propylene/ethylene tubular heat exchangers (2009)

Leakproofness inspection of propylene/ethylene tubular heat exchangers (2009)

Adding helium to the ethylene circuit and searching for traces of helium in the propylene circuit

  • Detecting leaks on two assemblies of three tubular heat exchangers
  • The exchangers are mounted in series on the ethylene circuit and in parallel on the propylene circuit
  • Leak located on a heat exchanger without shutdown of the facility
