The main purpose is to achieve a better separation of the components in the oil. In simple terms, it ensures that when material is drawn out of the distillation tower, the heavier components remain heavy and the lighter components remain light
Remove the excess heat from inside the tower； It serves two purposes in providing reflux to the tower.
Generally, a top loop is used to control the temperature at the top of the distillation tower in order to regulate the quality of the crude gasoline product. A middle oil loop is used to control the temperature in the middle section of the distillation tower, thereby controlling the quality of the light diesel product
Capture high-temperature thermal energy! Reduce internal recirculation in the tower! Control product quality! Control the gas-liquid phase equilibrium!
1. Ensure that product quality meets the required standards. 2. Utilize waste heat to reduce specific energy consumption.
