Hydrogen mixing process of heating furnace in coal tar hydrogenation unit can be simply divided into pre-furnace hydrogen mixing process,post-furnace hydrogen mixing process and partial pre-furnace hydrogen mixing process.By comparing and analyzing the three hydrogen mixing processes in many aspects,combined with their respective advantages and disadvantages,considering the actual situation of safety treatment,convenience and controllability of operation and investment cost under the condition of accident state,the hydrogen mixing process of heating furnace is selected flexibly and optimally in the design stage of the device,so as to ensure the stable,long and full optimal operation of the device after its completion and start-up.
