What is the impact of raw material properties on distillation?
Thread Content
This is the effect of raw material properties on the distillation unit: when the properties of the raw material become lighter, the top temperature of the tower is increased appropriately due to the rise in the vapor pressure; when it becomes heavier, the top temperature is decreased appropriately. After the raw material becomes lighter, it is necessary to increase the oil supply to the burner and raise the load on the heating furnace to ensure that the lighter portion of the oil vaporizes. The raw material becomes heavier, reducing the load on the heating furnace. But I don’t understand the latter part: when the raw material becomes lighter, the load on the heating furnace increases, and when the raw material becomes heavier, the load on the heating furnace decreases. Please help explain this. Thank you. As I understand it, the raw materials becoming lighter is what reduces the load on the heating furnace.
I don’t know if you’ve found the answer; I’ve seen it in the book now as well, but I still can’t understand it. If you understand it, please explain it to me as well
