Simple distillation of crude oil
(Reference No.)
Method A Simple evaluation of the crude oil can determine the type and characteristics of the crude oil: The crude oil can be easily distilled to obtain the yields of gasoline, kerosene, diesel, lubricating oil, etc. A2 Method Overview
The dehydrated crude oil is distilled at normal pressure and reduced pressure. The steaming process is divided into two parts: the first part is at 1333Pa (10mmIHg) pressure, steaming to 450℃ (Changzhou boiling point); the second part is at 133.3～266.6Pa (1～2mmHg) pressure, distilling to 500℃ (Changzhou boiling point)

Classification of key components of crude oil
Reference)
B1 The crude oil is subjected to simple distillation, and two key components with pressure boiling points of 250~275℃ and 395~425℃ are obtained by B2 distillation according to Appendix A (reference). The former represents the low boiling point component as the first component, and the latter represents the high boiling point component as the second component. The density of the two components can be determined according to GB1884 "Determination of Density of Petroleum and Liquid Petroleum Substitute Products by Density Meter (API Gravity)", or according to GB1885 "Oil Measurement Conversion Table" or the following formula to convert the density into API gravity:

Test Method for Saturated Vapor Pressure of Crude Oil (Air-to-Air Difference Method) (Reference)
This method is suitable for measuring the saturated vapor pressure of crude oil at various temperatures during the transportation process. C2 Method Overview
Use a German saturated vapor pressure tester. The set is a "locked door", the crude oil chamber is not filled with oil, the male-dairy is a "test egg" and the crude oil is filled with crude oil. The test is carried out: the test is a narrow range of oil and crude oil. The initial conditions must be studied. The crude oil is placed in a water bath. After the specified test temperature, the test symptoms are repeatedly stimulated. The difference between the maximum pressure read by the vigorous operation and the pressure produced by the spring is the pressure of the sample at the measuring temperature. C3 Instruments C3.1 Reid type saturated vapor pressure measuring instrument shall comply with the requirements of GB257 "Engine Fuel Saturation Test Method (Reid Method)", see Figure (1). The volume ratio of the gas pressure of the measuring instrument to the original gas pressure is 3.95~4.05. C3.21) Angle tube mercury pressure gauge shall comply with the requirements of GB257, see Figure c2. The slope of the glass tube is c5~8mm, and the scale plate measurement range is 0~800mm. Graduation price 1mm

C43 For oil tankers, oil tankers and ships, the "sampling cage method" is used to sample at the designated position. Pour part of the sample from the full sample container so that the sample volume in the sample container is 0%~80% of the container capacity: then wrap a larger seal with lead and stick a cup label. Send the experiment,

For transmission pipelines, sampling should be carried out before the pipeline is collected. Fill the sampler with the original sample, pour out part of the sample, so that the sampler is filled with 70%-80% of the container capacity. Immediately pack it in a soft and airtight box, attach a label, and send it to the experiment site (45). The sampler containing the oil sample should be kept airtight from the time the sample is obtained to the end of the test. It should be kept in a refrigerator or a cool place. If the sampler is found to have a leak, the sample will be discarded.
