SV10

• ASTM D7157
• ISO PAS 23263
• CIMAC guidelines

Easy

The SV10 is a straightfoward automated instrument that strictly follows the test method ASTM D7157.  The test preparation is simplified and the test is run unattended, simultaneously, on the 3 positions.

Wide range of applications

The SV10 has the ability to measures samples with asphaltenes concentration <0.4%.

It is compatible with crude oils, heavy fuel oils, residues, bitumens, marine fuels (VLSFO, ULSFO, …), asphalten free oils, tar sand crude oils, emulsions…

The presence of coke particles will not affect the measurement with the SV10, there is then no need to remove coke particles prior to run a test.

It allows:

• the monitoring and optimization of the refinerie processes: distillation, craking (thermal, hydrocracking) and visbreaking units
• the prediction and optimization of the oils blending: marine, power plants, …
• the monitoring and optimization of the tar sands dilution with light ends in the field
• the bitumen analysis and blending optimization

Increases precision

The temperature controlled high precision measuring cell (Licence TOTAL RC), combined with the simplified weighting procedure and automated toluene dilution of the SV10 are significantly improving the precision of the test. Indeed, the test is not anymore dependant on the ambient temperature, and the toluene dilution is precisely performed according to the sample‘s weigh, independently from the operator.

Reduces labor

The SV10 is a “Set it and Forget it” instrument. Once the titration cups are weighted and positioned on the instrument, the operator keys in the test details and starts the test. Then all the test phases (dilution, titration and cleaning) are automatic. The operator time is reduced to its minimum. At the end of the test, the titration results are displayed and the stability results are automatically computed and transferred if the SV10 is connected to a LIMS system.

Quality Procedure features

The SV10 has a built in result database. All details related to each test result are memorized. In addition, all information related to the instrumentcalibration is memorized to ensure a perfect traceability.

Increases safety

The SV10 totally eliminates all safety risks linked to the manipulation of hazardous solvents.

Very compact design

The 3 positions standalone automated SV10 instrument does not need much bench space: the width is only 44cm.

Running a test with the SV10 is straightforward and very easy, the operator:

          (1)    weight the sample(s)

          (2)    position up to 3 samples in parallel on the SV10 

          (3)    close the door and initiate the test(s)

Then the all procedure is automated: toluene dilution, heptane titration, measure of the flocculation point and cleaning. Detection curves are displayed in real time, and the SV10 computes the stability results according to the selected titration tests.

A detailed report of the titrations and S-value determinations are displayed and saved in the built-in database. They can be printed, transmitted to LIMS or copied to USB stick.

The final report includes:

• Date & time, sample name
• Xmin : minimum heptane consumption of undiluted oil to reach the flocculation (ml/g)
• FRmax : maximum flocculation ratio
• S : S-value (intrinsic stability of the oil)
• Sa : peptizability of the asphaltene
• So : peptizing power of the oil
• R2 : goodness of fit
• Titration tests & linear regression graph

• crude oils
• heavy fuel oils
• residues
• bitumens
• marine fuels (VLSFO, ULSFO, …)
• asphalten free oils
• tar sand crude oils
• emulsions
