It is related to many factors, including temperature, top pressure, backflow rate, blowing volume, and the properties of the crude oil
But considering only the effects of temperature and flow rate, quantity is fundamental: as the quantity increases, the temperature rises, the density increases, the freezing point goes up, and the color darkens； Of course, the temperature response needs to be more comprehensive, as there are far more thermometers on the tower than flow meters
It mainly depends on temperature, as the quantity lags slightly; however, flow rate can also serve as a reference parameter. Because under normal circumstances, the yield of diesel is fixed.
