Heating up of the gasoline hydrogenation furnace
Thread Content
This year, the lining of the heating furnace for gasoline hydrogenation was replaced; after the first replacement, the reactor was dried with a catalyst present. The furnace tubes are filled with nitrogen, and the temperature in the furnace chamber needs to be 540°C. There are no cross connections in the reactor; could heating the furnace cause the nitrogen temperature to rise above 400°C, thereby damaging the catalyst? Has this ever happened before?
We use steam to heat the furnace; the steam is vented through the outlet pipeline of the furnace, rather than passing through the reactor
