What is the purpose of mixing hydrogen before the hydrofining furnace?
Thread Content
Is it mainly to better control the reactor temperature? What are the advantages and disadvantages of mixing hydrogen before and after the furnace?
Hydrogen mixing in front of the furnace requires high-quality furnace tubes, thicker tubes, a high load on the furnace, significant investment costs; it is prone to flow imbalances, and the furnace tubes tend to coking； But it has advantages such as uniform mixing of oil and gas, stable reaction, and easy control of reaction temperature
Why does mixing hydrogen in front of the furnace produce those effects, such as coking?
Mixing hydrogen in front of the furnace reduces coking; the fast flow rate of hydrogen decreases the residence time of the material
