The SV10, the first fully automated S-value instrument developed by AD Systems under license TOTALEnergies RC is now widely used for the determination of asphaltenes stability in heavy fuels, atmospheric and vacuum residues, visbreaking feed and other residual distillates.

Today’s market is very demanding for a reliable analytical tool capable to measure asphaltenes stability in crude oils and their mixtures.
AD System’s engineers made it possible performing fine tuning of the SV10 firmware combined with slightly modified hardware, especially adapted for crude oils testing.
In a recent study involving 12 crude oils of diverse origins with asphaltenes contents ranging from 0.3% to 3.5% (m/m), the SV10 equipped with updated firmware consistently detected asphaltenes flocculation on light crude oils, demonstrating very high sensitivity.

This new achievement confirmed that the SV10 can be successfully applied for evaluation of asphaltenes stability in crude oils and their mixtures even at very low concentrations.
Beyond the ASTM D7157 standard report (S-value, So, Sa), the SV10 calculates IN (Insolubility Number) and SBN (Solubility Blending Number), as well as the estimation of stability reserve and blending potential.
These values for crude oils or fuels give essential information for the assessment of their compatibility and blend stability while blended at different ratio.
The SV10 is the perfect analytical tool to increase efficiency of refining and blending operations.

Powered by innovation and the industry demand, AD Systems  has developed an automated solution to analyse iron corrosivity of fuels, turbine oils, hydraulic fluids, and to evaluate performance of corrosion inhibitors.
The complete solution consist of the automated bath for iron corrosivity CB10 in accordance with ASTM D665, NACE TM0172, ISO 7120 and automated corrosion rater CT10. 

The CB10 bath was engineered to minimise operator time and run corrosion test fully unattended. After installing a beaker with 300ml of the sample in one of the test positions and selecting the test method (standard or customized) on the touch screen, the entire procedure is fully automated: sample heating, stirring, insertion of test specimen (spindle), injection of distilled or synthetic sea water, temperature, and test time controls. 
A new instrumental approach developed by AD Systems for evaluation the test rod surface for the presence of rust is time saving and drastically reducing operator subjectivity. Using a digital camera with a specific image analysing algorithm, the CT10 enables quick, accurate and objective rating according to the selected method: The combination of CB10 bath and CT10 rater provides automated testing with precise and traceable, fully documented test results.

AD Systems is pleased to announce the inclusion of our innovative Jet Fuel Thermal Oxidation Stability analyzer TO10 in the Table 1 of ASTM D3241.  The updated test method D3241-24 has been recently published by ASTM and available on-line.

The testing laboratories and refineries can now officially use the TO10 model to certify Jet Fuels in according to ASTM D1655, D7566 and other specifications.

The research centres developing new generation of Sustainable Jet Fuels (SAF) will appreciate the versatility of the TO10 covering very large temperature range and suitable for non-conventional samples with increased viscosity or density.  

The new equipment is designed to bring the precision of this important test method to the next, till now, unmatched level. All critical test parameters were carefully studied and state-of-the art engineering solutions were implemented into the TO10 to reduce errors, improve accuracy and reliability.

If referee automatic tube rater ITR – DR10 (ASTM D3241 Annex 2) is connected, the transfer of heater tube scan is automatic and the D3241 test report will be completed with the deposit thickness profile.  The TO10 is well suited for any type of application from routine testing to research work on sustainable aviation fuels.
