GOST R 53707
Petroleum products. Method of distillation at atmospheric pressure
The scope of the method lies in the fact that 100 cm³ of the sample is distilled under the conditions prescribed for the group, which includes the sample. The distillation is carried out in a laboratory batch plant under conditions that are designed to provide fractionation with approximately one theoretical plate. Systematic observations of temperature readings and condensate volumes are carried out depending on the user's needs. The volume of the residue and the loss are also recorded.
The National Standard of the Russian Federation GOST R 53707 establishes a method for distilling petroleum products at atmospheric pressure using a batch-operated laboratory unit to quantify the boil-off limits.
The method is used for products such as:
- light and medium distillates;
- fuels for spark ignition automobile engines;
- fuels for automobile engines, which contain up to 10% ethanol;
- aviation gasolines, aviation turbine fuels;
- diesel fuels 1-D and 2-D, mixtures for biodiesels up to 20%;
- marine fuels;
- special petroleum ethers;
- naphtha;
- white spirits;
- kerosene and nozzle fuels of grades 1 and 2.
The test method is not applicable to products that contain appreciable amounts of residual material.
The test method under consideration provides for the use of both manual and automatic devices.
The basic method for determining the boiling point of a petroleum product using a simple batch plant has always been used as long as the petroleum industry has existed. It is one of the oldest test methods in use since the time it was referred to as an Engler distillation. Since the method has been used for such a long period, a lot of data has been accumulated necessary to evaluate the behavior of the product or the processes themselves during distillation.
