Operation of fractional distillation to increase reaction depth and processing capacity
Thread Content
1. As the reaction depth increases, the distillation temperature should be lowered. 2. When the amount of material undergoing reaction increases, the distillation temperature should be raised. I seem to have seen someone on a forum say something similar regarding C Super Edition; I’d like to know the reason behind this~~~

The control dry point for the extraction temperature of light diesel may vary among different refineries, as may the control freezing point. If it is the top temperature of the distillation tower, try to explain: The top temperature of the distillation tower is a key parameter for controlling the dry point of crude gasoline. The factors affecting it include: 1) the reaction feed rate, feed properties, reaction depth, top pressure of the distillation column, steam flow rate, extraction temperature of light diesel, cold return flow rate, top circulation volume and temperature of the top circulation column, as well as the amount of rich absorbent oil returned to the column and its return temperature. 2. The dry point of crude gasoline is the dew point temperature at its own vapor pressure. At lower vapor pressures of oil and gas, the dry point of the same crude gasoline obtained through distillation is higher. 3. As the reaction depth increases (within a certain range), the gasoline yield rises; to maintain the same dry point, it is necessary to raise the temperature at the top of the distillation column (with all other conditions unchanged). 4. As the amount of material processed in the reaction increases (with all other conditions unchanged), the total gasoline production rises; to maintain the same dry point, it is necessary to increase the temperature at the top of the distillation tower (with all other conditions unchanged).
