  • Modelling of Naphtha Cracking for Olefins Production

    4. Steam cracking furnace A mathematical model of a naphtha cracking furnace with a SRT-VI coil is developed, which will be used to simulate typical operation and to compare the model predictions to data. Typical geometry and operating conditions of the coil were taken from available literature [9]. Figure 4 shows the coil design.

  • Understanding the Most Common Heat Exchanger Problems

    Cracking Perhaps the most common problem with heat exchangers is cracking of the metal. A cracked heat exchanger can release soot and combustion gases into the air stream, which presents a serious health risk to the occupants.

  • Typical failures in pyrolysis coils for ethylene cracking ...

    In most cases there is a combination of factors which ultimately lead to the failure, e. g. carburization and creep ductility exhaustion. This results in bulging, bending and ovalisation of the tubes. Also, brittle fracture during furnace trips can result in large, longitudinal cracks on many tubes in the furnace.
