Experimental Modelling of the Fluid Flow in a Furnace Top of an Ethane Cracker in EPEMSB, Paka.

The problem encountered is the induction fan of an ethane cracking furnace at Ethylene
Polyethylene Malaysia Sdn Bhd (EPEMSB) failed suspected due to induced turbulence.
A model of a furnace top must be created to simulate the flow in the furnace top to
analyze it, troubleshoot the possible root causes and postulate methods or approaches to
prevent reoccurrences. From the previous FYP, this model were experimented but there is
several problem encountered during the experiment. One of the problem is there is
leaking within the test rig, improper pump selection, bubble air trapped in the top of the
test section and the shift of the centre of mass of the damper flapper system. The test rig
must be modified to overcome these problems, which is the main subject matter of this

documentation. From the previous experiment, the root cause of the problem is the high
induced turbulence in the furnace top. However there is a need to analyze the possible
root cause of the induced turbulence.
