As the properties of crude oil become lighter, does the bottom temperature increase or decrease? What is the impact of an increased flow rate of crude oil into the tower?
When the operating conditions remain unchanged, the bottom temperature of the tower increases, and the amount of light components at the top of the tower increases. If the feed to the tower is increased without adjusting the bottom temperature of the tower, it will definitely drop.
If the temperature at the bottom of the tower increases, what will happen to the temperature at the top of the tower? What will happen to the side-stream distillation temperature?

If the feed to the tower is increased without adjusting the temperature at the bottom of the tower, it will definitely drop. Do you mean the decrease in temperature at the bottom of the tower? Will the liquid level at the bottom of the tower still drop?
If you operate it at the console yourself, you’ll understand; right now you’re only dealing with theory. In practical operations, material balance, heat balance, and gas-liquid phase balance must be taken into account.
The temperature at the bottom of the tower will rise, and high flow rates can cause erosion due to fluid flow.
When crude oil becomes lighter, there must be corresponding actions taken; who can guarantee that the specifications of the raw material remain the same every time? His question is purely theoretical!
As the properties of crude oil become lighter, the amount of distillate at the top of the tower generally increases, while the pressure at the top of the tower and the temperature after cooling rise； Relatively speaking, the load on the heating furnace will increase, as more heat is required for vaporization ；
