Comparison with actual plant data shows it is accurate enough for real-time optimization
A new simulation algorithm for industrial cracking
furnaces significantly increases simulation speed with
satisfactory accuracy. The energy-balance equations of
cracking furnaces were transformed to the temperature
differential equation by directly solving a quartic equation
of the tube wall temperature. One set of new continuity
equations for various reactants, temperature and pressure was
formed.
The new algorithm greatly reduces the number of
complex iterations during the actual simulation, and
simulation speed is fast enough to accomplish a periodic
simulation of a cracking furnace in just a few minutes with a
