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.
