Gas is used as raw material in the operation of tubular furnace,and there is an open flame,which is easy to happen gas poisoning,fire and explosion.Based on the experience of transforming the oil-rich heating method from pipe furnace gas to steam heater in the crude benzene distillation section of D plant for many years,the paper compares the two oil-rich heating methods from four aspects,including process index control,economic benefit,environmental discharge and operation safety.After switching to steam heating,the stability of process control is greatly improved,the energy consumption is reduced,and the yield of crude benzene is significantly increased,so that the steam heating technology of oil-rich heater is more advantageous.
