Dry point: As the oil components evaporate gradually based on their boiling points, the temperature of the gas phase also increases. The highest temperature reached at the end of the distillation process is known as the final boiling point or dry point. ============================== ☛“Petrochemical Special Zone”’s announcement regarding the selection and rewards for outstanding moderators, technicians, and star members from January to July 2016: http://bbs.hcbbs.com/thread-1608031-1-1.html (Source: Haichuan Chemical Forum) ☛ The second round of evaluations for outstanding management members at Haichuan – taking place in August and September; the top prize is a Xiaomi tablet: http://bbs.hcbbs.com/thread-1609580-1-1.html (Source: Haichuan Chemical Forum)
Dry point (DP) is the temperature, expressed in °C, at the instant when the last drop of liquid evaporates from the lowest point of the distillation flask during the determination of the boiling range under specified conditions.
Temperature of instantaneous evaporation during liquid distillation
The temperature at the instant when the last drop of liquid evaporates from the lowest point of the distillation flask during the determination of the boiling range of petroleum products under specified conditions
Temperature at the instant when the last drop of liquid evaporates from the lowest point of the distillation flask
In the determination of the boiling range of oils under specified conditions, it is the temperature at the instant when the last drop of liquid evaporates from the lowest point of the distillation flask, expressed in °C.
In the determination of the boiling range of oils under specified conditions, it is the temperature at the instant when the last drop of liquid evaporates from the lowest point of the distillation flask, expressed in °C. Common minerals such as gasoline; if it is vehicle gasoline, it should be a fraction with a dry point of less than 205°C. Diesel (light diesel) has a 95% dew point not higher than 365°C, a 90% dew point not higher than 355°C, and a 50% dew point not higher than 300°C. The boiling range of diesel fuel for vehicles remains the same as before. Generally, the initial boiling point of diesel is above 150°C, which is determined based on the actual product specifications of the refinery. The above refers to the **standard specifications for the boiling range of gasoline and diesel. Petrol and diesel, which are generally used as intermediate products (more precisely, naphtha fractions and diesel fractions), cover a wide range; in particular, the range for diesel fractions can be from 150°C to 370°C.

As the oil components evaporate gradually based on their boiling points, the temperature of the gas phase also increases. The highest temperature reached at the end of the distillation process is known as the dry point.
The point at which oil distillation continues until the highest vapor temperature is reached is called the boiling point. The temperature at which the last drop of the sample in the flask disappears is called the dry point
The temperature at which the last drop of liquid vaporizes during oil distillation
