AD Systems products

The AutoREID apparatus from AD systems is an automated Reid Vapor pressure instrument in full compliance with ASTM D323-B, ASTM D4953, and similar standards. These methods are for the determination of vapor pressure of gasoline, volatile crude oil, and other volatile petroleum products. The Reid method is particularly suitable for determination of vapor pressure of crude oil for transportation, storage and general handling purposes. The instrument directly measures the Reid vapor pressure without correlation or calculation. Automated Reid Vapor Pressure - ASTM D323, D4953, ISO 3007, IP 69.

A new instrumental approach for measurement of corroded surface area has been developed by AD Systems in which the exact percentage of corroded area is accurately determined by an automatic instrument reducing test subjectivity. The operation is based on a homogeneous lighting source, CCD camera, specimen rotation system, and specially designed application software. With CT10 the corrosion rating is now very repeatable and fully documented. ASTM / NACE Corrosion Rater, ASTM D665, D7548, NACE TM0172, IP 135, ISO 7120, JIS K2510.

Thermal Oxidation Stability of Aviation Turbine Fuels, ASTM D3241 is universally used by the industry to measure high temperature stability of aviation turbine fuels.  The ASTM D3241 is required to be run on every batch of jet fuel produced according to ASTM D1655, D7566 or DEF STAN 91-91 specifications. In this test method, the fuel is pumped through heater tube at fixed flow rate and during a specified period of time. The fuel is pass or fail rated according to the amount of deposit formed on the heater tube at a specified temperature. The test results are indicative of fuel performance during gas turbine operation and can be used to assess the level of deposits that form when liquid fuel contacts a heated surface that is at a specified temperature.

The automation of the smoke point test introduced by AD Systems had drastically improved the precision of the test in comparison with the original manual method, and consequently became the referee test method in jet fuels specifications. Performing the smoke point test manually requires highly skilled technician with years of experience. Additionally, the manual test is time consuming. Automated Smoke Point Tester ASTM D1322, D1655, IP 598, Def Stan 91-91.

Asphaltenes are defined as the insoluble fraction in n-heptane and soluble in toluene and represent the heavier and more complex fraction of crude oils, residual re?nery streams, fuel oils or marine fuels.  Asphaltene’s tendency towards precipitation and deposition often causes serious problems in upstreaam and downstream operations :sludge formation, filter plugging and loss of pipes efficiency. To keep the asphaltenes in solution and have a stable fuel, there should be a balance between the fuel and asphaltene aromaticity.

The ASTM D3241 / IP 323 Thermal Stability test is one of the most important tests for the jet fuel quality control. The TO10 revolutionizes this routine  test of jet fuels by bringing unmatched operation simplicity and reliability of test results. The operator work is simplified to its maximum: a dedicated gauge allows easy and perfect tube positioning in the test section, no tools are needed to assembly the test. The smart software control and monitor all test conditions in real time. Thermal Oxidation Stability of Aviation Fuels Oxidation Stability Test Rig, ASTM D3241, IP 323, ISO 6249, ASTM D1655, D7566, DEF STAN 91-091.

The Video Distillation VD10 revolutionizes distillation testing by bringing unmatched automation and precision to the analysis of atmospheric distillation of petroleum products. Powered by innovation, the VD10 analyzer revolutionizes this routine analysis of petroleum products by providing unparalleled automation and precision. The powerful algorithm assisted by video camera (patent pending) analyzes in real time the boiling behavior of the sample in the flask during the distillation run and applies optimal heating to strictly respect conditions of the chosen method.
