I’ve just started learning about *top plates*. I would like to ask Chai Jia and Qi Jia about the indicators that need to be monitored, and how to make adjustments when these indicators are not within the acceptable range

I’m a beginner!

It should be included in these operating procedures

It’s as if you didn’t say anything; you also didn’t mention anything that was incorrect, so how can one know what needs to be adjusted? Buy two books on hydrogenation operators for diesel and gasoline, and read them to understand the basic operations and principles. It’s available for sale online; once you look at it enough, you’ll understand

Yeah, it’s too vague – there are no specific metrics, nor any concrete methods for making adjustments!

It’s my fault! I’ll just ask you directly! Which parameter of diesel is primarily affected by the top temperature of the distillation tower?
Reply #62016-06-17
Is there a stripping tower in front of the distillation column? If it only affects the diesel distillation range, initial boiling point, dry point, and density, then if there is no stripping, it has little impact on the sulfur content

Without stripping, does the density of diesel decrease if the temperature at the top of the tower is high?

Do you use a mixture of diesel and gasoline for processing? ? The temperature at the top of the diesel distillation tower affects the flash point of diesel and the final boiling point of gasoline. It would be best to describe your process
