Calculation of the heat load for sulfur recovery reactors
Thread Content
When calculating the sulfur recovery reactor, if one wants to raise the temperature to 1350 degrees, I would like to know what the heat load of the reactor should be, or what factors influence it. If there is a specific formula, I would be extremely grateful!
Enthalpy of combustion and enthalpy before and after the reaction, mass balance and heat balance.

To calculate the heat load of a sulfur production furnace, it is usually necessary to know the diameter of the furnace, the residence time (typically 1–1.5 seconds), and the calorific value of the fuel gas. When using refinery gas, its calorific value is usually around 9,000–10,000 kcai/nm3. However, for acidic gas conditions, the calorific value is determined based on its components. The above are only rough estimates; for precise calculations, relevant software is used in the end.
I have also been working on this area recently, but the computational load is enormous, and there are various algorithms available! It’s closer to what’s actually needed; I suggest you search for the article titled “Renovation of the waste heat boiler in Unit 2 of the sulfur recovery plant at Jiujiang Petrochemical Complex”.
The enthalpy value of the inlet material and its temperature, as well as the enthalpy value and temperature of the outlet material – by calculating the difference between these values, the load is obtained
This is the basic principle; the actual calculations involved are far more complex than one might think!
The most important factor is the concentration of hydrogen sulfide in the acidic gas; it is estimated to be below 60%, so there’s no way it will work.
