Fire incident at a CCR Unit
8
A major fire took place in CCR (Continuous Catalytic Reformer)unit at level transmitter (LT) of the 2nd stage suction Knock-OutDrum (KOD) of Net Gas Compressor.
Cause of Fire:Passing of valve(s) from KOD-03, which was at a pressure of15 Kg/cm2 (g) at the level troll, resulted in accumulation of H2into the level troll. In fact KOD-03 was isolated by closing asingle valve without any positive isolation.
Opening of the flange on the drain line resulted in release of H2and Naphtha from the level troll which caught fire either byauto-ignition or due to generation of spark whilehammering the line by not using (non-sparking tools) to de-choke the line.
