Numerical simulation of flame propagation characteristics from ruptured furnace wall of a naphtha reformer

Abstract

Petrochemical plant is dealing with high temperature and high pressure conditions that must be handled properly. In particular, the reformer as the main equipment of the plant to decomposing naphtha is a high-risk facility. If any failure, such as cracks in the pipes inside reformer is happening, it can cause leakage and explosion may occur. In this study, the event of an accident by a leakage of the inner tube in reformer is evaluated using a numerical analysis with respect to the occurrence and spread of the flame. The result is visualization of flame and hazard area.
