During reorganization of UOP3.5 when it is raining, what adjustments need to be made for internal operations?
When it rains, the temperature is affected, and temperature directly influences the pressure inside the tower; therefore, operators should focus on adjusting the pressure.
I was wondering if there are any differences in operating UOP 3.5 compared to before? I’m referring to the regeneration control aspect, not the overall process
When it rains, one needs to be vigilant regarding the possibility of instrument malfunctions. In cases of severe convective weather such as thunderstorms, precautions must be taken to avoid electrical shocks. If the sewage drains are not functioning properly, it is necessary to go to the site to check the operation of the systems designed for separating rainwater from sewage, in order to prevent environmental safety incidents. This is how it is adjusted on standard devices; it’s a common issue.
If it rains, the temperatures of the air electric heater and the regenerative gas electric heater will drop; be sure to adjust the temperatures accordingly, while avoiding excessive temperatures on the surface of the electric heaters.
Rain should have a relatively minor impact on the regeneration system, as the electric heating devices and thermocouples are not exposed to the outside. However, if it rains for a long time, attention should be paid to the risk of the thermocouples failing. At the onset of rainfall, it is necessary to pay attention to the impact on the pressure in the reaction system. A decrease in the temperature of the product’s air cooling can lead to an increase in hydrogen purity, which in turn raises the pressure in the reaction system. It is important to adjust the operations related to the product’s air cooling and the compressor in order to maintain stable pressure; large pressure fluctuations can also cause the regeneration process to stop. That’s all I can remember for now.
The treatment of exhaust gas emissions in the regenerator is different; the 3.5 model uses a separation hopper to absorb chlorine from the exhaust gas
Well, in the event of rainfall, activating two additional electric heaters will automatically increase the power, which can lead to an alarm regarding the surface temperature of the tube sheet. Are there any other things to keep in mind regarding the regeneration system?
If the speed of the hydrogen compressor in the reforming process needs to be increased, then the booster pump used in the reforming process also needs to have its speed increased, right?

There’s no need to increase the speed of the circulating hydrogen compressor; increasing the speed doesn’t change the hydrogen-to-oil ratio. Increase the speed of the booster pump, while being careful to prevent surge; open the anti-surge valve if necessary. I'm referring to situations with heavy rain here; in case of light rain, just make slight adjustments based on pressure changes
Weather changes at a single point in time have little impact on the device; however, seasonal changes have a greater effect. If we consider just one specific time point, it seems that air cooling is likely to have a significant impact
