Petrochemistry

The PourPointTester research device is a small-sized automated laboratory device for determining the pour point (pour point) of oil and petroleum products using the rotational method with high accuracy (according to the ASTMD5985 method).

Application

Determination of fluid pour point in accordance with ASTMD5985 standard
Determination of pour point according to ASTMD97 standard (calculated by software)
Determination of fluid temperature during the experiment
Study of the effectiveness of depressants (additives) that increase the pour point of oil.
Temperature range: - 55 C⁰ - +150 C⁰

Advantages

The presence of a modern thermoelectric module allows experiments to be carried out without the use of a cryostat;
Small amount of coolant required;
High reproducibility of the experiment;
Compact dimensions;
Possible use in field conditions;
Safe transportation thanks to the presence of a convenient case on wheels (optional);
Possibility of transporting the device in the aircraft cabin (if there is a case);
Can be used anywhere in the world thanks to a wide range of input voltages;
User-friendly software;
Ability to save up to 10 different experiment configurations offline;
Fully automatic experiment execution;
When using a computer, an unlimited number of experiment configurations can be saved.

Device software functions

Create and save an unlimited number of experiment configurations;
Monitoring and control of experimental parameters;

Automatic preparation of an experiment report.
When using the device without connecting to a computer (as a stand-alone instrument), it must be possible to save up to 10 different experiment configurations in the device’s memory.

Operating principle of the device

In accordance with the ASTMD5985 standard, the sample container rotates slowly (approx. 0.1 rpm) around its axis with a freely moving temperature sensor (rod) placed in the sample. If the viscosity of the sample increases (reaches the pour point) the temperature sensor (rod) deviates from the vertical position. During the experiment, the sample temperature is constantly measured with an accuracy of 0.1 °C. Thanks to the measured data (the angle of deflection of the rod and the temperature at which the deflection occurred), the freezing point of the fluid is automatically calculated in accordance with the standards. Accuracy: = ±0.1 ⁰С. The fluid temperature is measured directly by placing a temperature sensor (rod) in the fluid. Thermal behavior is determined during fluid cooling and provides insight into crystallization because crystallization slows down the cooling process.

To obtain accurate results, it is necessary to conduct the experiment at least 9 times and calculate the root mean square values of the freezing point.
