Three dimensional coupled simulation of furnaces and reactor tubes for the thermal cracking of hydrocarbons

摘要

Thermal cracking of hydrocarbons has gone through a significant evolution over the past 20 years. Improved metallurgical properties together with a better understanding of the chemical aspects have led to new configurations for furnace and reactor, all aiming for high severity cracking. A full 3D CFD model containing transport equations for mass, momentum and energy has been implemented in the software code FLOWSIM, together with the κ-ε turbulence model.
