Temperature in the evaporation section of the distillation column
Thread Content
In the evaporation section of the coking distillation tower, the temperature remains at 400 degrees for long periods of time, while the temperature at the bottom of the tower is 360 degrees. Due to severe blockage in the tubes of the circulating oil heat exchanger, the heat exchange efficiency is very poor; as a result, the temperature in the reverse column is very high, making it difficult to control. This temperature in the reverse column ranges from 270 to 320 degrees. Under such conditions, could serious coking occur at the bottom of the distillation tower?
Reduce the tower temperature, lower the bottom temperature of the tower, and decrease the residence time of oil at the tower bottom
