Hydrocracking reactor bed temperature control
Thread Content
My unit is a 700,000-ton catalytic reforming unit with a pressure of 120 kilograms; two reactors are connected in series – one for refining and the other for cracking. The bed temperature varies at times, being stable at other times. Do any of you have any methods to stabilize the bed temperature without reducing hydrogen consumption?
This is mainly determined by your raw materials, right? In other words, if the properties of your raw materials are stable and the supply is consistent, then the temperature of your reactor will also be stable; once it’s adjusted properly, there’s basically no need to make any further changes. If the feed isn’t stable, then any attempts to adjust the settings are pointless. Everything is now under automatic control, and everything runs smoothly. I’m not sure what exactly you mean by stable control.
The feed is stable; I’m not sure if you control the reactor inlet temperature. Here, in addition to maintaining a stable feed, we also control the reactor inlet temperature
The properties of the raw materials should be as stable as possible; in addition, the inlet temperature of the reactor can be controlled
I tried it and it worked to some extent; it’s much more stable than before. What’s the scale of your devices?
Factors affecting reaction temperature: An increase in sulfur content, nitrogen content, and hydrogen purity leads to an increase in bed temperature. Moisture in the raw material feed, fluctuations in bed temperature
