1、Project 4 Analysis of the evaporative properties of the oilEvaporation performancedistillation range vapor pressure and other indicatorsPure liquid substances have a constant vapor pressure at a certain temperature.Oil is a multi-component mixture with a continuous boiling point.At a certain externa
2、l pressure,the boiling point range of the oil is called the boiling range.the oil product is distilled under specified conditions,Temperature range from initial distillation point to final distillation point,Called distillation range.The distillates distilled out in a certain temperature range are c
3、alled fractions,Such as Gasoline distillate Kerosene fraction,etc.A narrow temperature range is called a narrow fraction,A wide temperature range is called a wide fraction.a set of data corresponding to distillate temperature and distillate volume fraction in distillation measurements of petroleum p
4、roducts,Called fraction composition.For example,the initial distillation point is the temperature of the first drop of liquid appearing from the condenser pipe during distillation,10%Distillation point is the temperature at which 10mL of liquid is collected in a 100mL determining cylinder,By analogy
5、,There are still 50%distillation point 90%distillation point and final distillation point,These points are called the distillation range in practical production,It is the main index to evaluate the evaporation of petroleum products.(1)The distillation range can judge the fraction composition of petr
6、oleum fractions.And serve as the basic data of plant design For example,when deciding a crude oil processing scheme,It should first understand the relative content of light and heavy fractions contained in crude oil and the yield of light fractions,such as gasoline,kerosene and motor diesel oil thro
7、ugh atmospheric distillation and vacuum distillation,At the same time,the properties of fractions should be analyzed in detail.It is most suitable to judge crude oil from the amount of yield and the quality of properties of each fraction,Product Programme and Processing Programme.(2)The distillation
8、 range is the basis for the production operation control of the plant The regulation and control of the production operating conditions of the distillation unit is based on the distillation range data of the distillate,For example,the operating temperature at the top of the column may be determined
