Tube Rupture in Hydrodesulfurisation Heater During Hydrogen-Only Start-Up
A vertical cylindrical hydrodesulfurisation reactor charge heater was being started up with hydrogen flow only rather than hydrogen plus oil as in normal operation. As a result of the low heat load only a couple of the burners were being fired. The uneven firing resulted in one pass of the furnace being overfired and a tube ruptured. This problem was solved by installing a single centre burner for start-up. In addition multiple skin thermocouples were installed on each tube pass at the hottest points.
