Diesel hydrogenation heating furnace
Thread Content
Hello, teacher. The outlet temperature of the diesel hydrogenation heater fluctuates significantly. What is the reason for this, and how can it be addressed?
Reactor or reboiler? Fluctuations in feed volume, fluctuations in the properties of the feed (water content in the raw materials, especially relevant for reaction furnaces; the amount of light components, etc.). For reaction furnaces, it is also necessary to consider whether there are fluctuations in the amount of recycled hydrogen, such as the operating range of the recirculation pump, as well as whether the pump is experiencing surge phenomena. There can also be fluctuations in the pressure of the fuel gas, along with issues related to instruments. That’s about it. Once you understand the approach, just follow the steps accordingly.

What are the harms caused by improper handling? It’s not easy to describe
Fluctuations in water content, large variations in raw material amounts, and unstable fuel gas can all cause fluctuations in the output
