What are the reasons for changes in the dry point of gasoline in atmospheric and vacuum distillation units?
The dry point of gasoline is determined by the content of heavy components in the fuel. A higher dry point indicates an increased amount of heavy components in the fuel, meaning that the temperatures at the 90% cut and the dry point are higher – this is what is commonly referred to as the heaviest fraction of the fuel.

Affected by factors such as the top temperature of the tower, pressure, temperature of the feed entering the tower, variations in the density of the feed entering the tower, changes in the flow rate and temperature of the reflux at intermediate stages, changes in the flow rate of side products, pressure and flow rate of the gas blown at the bottom of the tower, whether the reflux oil from the top contains water, and salt blockage in the tower plates, the top temperature of the tower is the main means of adjusting the dry point of gasoline. When the pressure at the top of the tower decreases, the top temperature should be reduced accordingly, and vice versa.
