What factors affect the temperature rise in the hydrofining reactor?
Thread Content
The temperature rise in the hydrogenation refining reactor is relatively low. Considering the feedstock, what are the factors in the feedstock that affect the reactor’s temperature rise? What types of raw materials can be used to increase the temperature rise and reduce the load on the reaction furnace?
The olefin content in the raw material is like that of firewood. Raising the temperature of the fuel quickly can reduce the load on the reaction furnace
Due to the high sulfur content in the feed oil, and because the hydrodesulfurization reaction proceeds rapidly and is an exothermic reaction, an increase in the sulfur content of the feed can lead to a significant rise in the temperature of the catalyst bed at the reactor inlet, thereby reducing the load on the reaction furnace.
From the question you raised, it seems to be about the energy consumption of the heating furnace. If the reaction temperature rises, the exit temperature of the reaction products increases, as does the temperature at which heat is exchanged with the raw materials. An increase in the inlet temperature of the heating furnace leads to a decrease in fuel gas consumption; however, it should be taken into account that hydrogen consumption will also increase significantly. Therefore, we need to consider all these factors together.
