For a tubular furnace in which the medium inside the tubes is natural gas, and the flow rate, pressure, and inlet/outlet temperatures are known, how can the total heat load be calculated? After reading the book on process calculations for tubular furnaces, it became necessary to find out the enthalpy of gas components such as methane at corresponding temperatures and pressures. I searched online for a long time but was unable to find any relevant data; the inlet and outlet temperatures are 30°C and 600°C respectively, with a pressure of 200 KPa. I wonder how everyone calculates it?

Thank you very much. I’ll go and learn* it first
Why aren’t there any parameters for pressure in this table? The enthalpy values must vary at different pressures, right?
