DEVICE FOR EXPRESS EVALUATION OF PETROCHEMICAL LIQUID QUALITY AND METHOD OF ITS IMPLEMENTATION Russian patent published in 2017 - IPC G01N29/02 G01N11/16 

FIELD: chemistry.

SUBSTANCE: analysis of a mixture of hydrocarbons is set in the range of 0 to 350°C. It is also possible to assess the quality of more viscous and high-boiling mixtures of hydrocarbons thanks to the vacuum chamber unit. At the same time, the hydrocarbon mixture is analysed at a temperature of 110 to 270°C and a vacuum of 0.1 to 100 mm Hg. There is no decomposition of the hydrocarbons contained in the sample. Applying an airflow speed block in the claimed device, energy consumption and analysis time are reduced, in return for more energy-consuming heating elements. Herewith the evaporation of the petrochemical liquid occurs under the action of an additional air flow around it with a velocity of 0 to 6 meters per second.

EFFECT: ability to determine the quality of liquid low boiling and high boiling hydrocarbons, improving the accuracy, stability and reducing the analysis time.
