Abstract:

The cracking furnace is core reactor of ethylene plant. The computer simulation and optimization calculation of cracking furnace and the implementation of optimization calculation results are important means to ensure the ethylene cracking unit to run efficiently, steadily, safely and stably for a long period. The core of computer simulation and optimization software development for ethylene cracking furnace is the kinetic model of cracking reaction. Based on 3 kinetic models of pyrolysis reaction:empirical model, molecular reaction model and free radical mechanism model, the development and application of simulation and optimization software systems for ethylene cracking furnaces, such as SPYRO and EpSOS are introduced. It is pointed out that simulation and optimization software system for ethylene cracking furnaces has important application value in ethylene production by steam pyrolysis. Its research and development and application should be given adequate attention.
