②Jet fuel has a high initial boiling point, 90% or dry point, and a low freezing point (so-called heavy head and light tail). The reason is the low flow rate of jet fuel leaving the unit, high pressure in the atmospheric tower, and high temperature at the top of the atmospheric tower. During adjustment, the flow rate of the jet fuel leaving the unit should be increased, the temperature at the top of the atmospheric tower should be reduced, and the pressure in the atmospheric tower should be stabilized. ③Jet fuel has a low initial boiling point, a high 90% cut or dry point, and a high freezing point (what is known as a light head and heavy tail); this is due to the large flow rate of aviation kerosene leaving the unit, a low temperature at the top of the atmospheric tower, and a low pressure in that tower. The top temperature of the atmospheric tower is low; during adjustment, the flow rate of jet fuel leaving the unit should be reduced to increase the top temperature of the atmospheric tower.

My understanding is that if it is a stabilizing device used to stabilize the pressure in the constant-pressure column, then the temperature at the top of the column needs to be well controlled. Flow rate is the main means of regulation. If you are looking for control points, first follow the pressure control parameters provided by the design institute; it’s necessary to stabilize one method of control first before using other approaches
The general idea is correct, but this is a method for dealing with production problems; I’m asking whether there are any issues with the specific methods used
