ASTM D7668 for CID 510 Approved in 3 Diesel Specifications

CID 510 now officially listed in: ASTM D975, ASTM D6751 and ASTM D7467

PAC CID 510 - Cetane Ignition Delay

The PAC Herzog CID 510 provides highly accurate Derived Cetane Number (DCN) analysis for diesel fuels with excellent correlation to the CFR Engine. Its test method ASTM D7668 for our CID 510 can now officially be used as an alternative test method to the CFR Engine acc. to ASTM D613 to certify diesel fuel. Three new revisions of the diesel fuel specifications D975, D6751 and D7467 were recently published by ASTM and can be downloaded from the ASTM website.

As part of the method development process, ASTM and the Energy Institute conducted an extensive interlaboratory study in March of 2013. In the ILS, 17 laboratories participated from the United States and Europe to compare the cetane number determined with the referee method, ASTM D613 (CFR Engine Technology) and the derived cetane number determined with the ASTM D7668 (CID 510). The precision of the CID 510 (ASTM D7668) from the ILS study is much better than traditional CFR Engine technology (ASTM D613), as well as other CVCC instruments (ASTM D7170 and ASTM D6890). In addition to high precision, the CID 510 provides excellent correlation to the mean value of the CFR Engine.CID 510

When comparing the CID 510 to the CFR Engine costs can be reduced by 80%. You can save on calibration, labor and consumables for sample testing, plus the savings on the initial investment, which ultimately increases a refinery’s profitability.

“With other technologies, refineries had to compensate for less precise centane number results in Diesel by adding more cetane improver to the process just to make sure they do not go below the minimum specification requirement for cetane number”, says Thomas Herold, PAC’s Product Manager. “With the excellent precision and correlation of our CID 510 technology, refineries are able to run their process closer to the true specification limit for the cetane number of diesel, allowing them to add just the right amount of Cetane improvers and achieve significant cost savings. For a refinery producing 100,000 barrels of Diesel per day, operating at 1 cetane number closer to the specification could save as much as $800,000 USD per year.”

In addition to high precision, the CID 510 has significant benefits. It is easy to use with fully automated measurement and one push button operation, as well as automated calibration. It also contains enhanced safety features, such as a built-in fire monitoring and suppression system, over pressure protection for the fuel injection system and combustion chamber, and a fuel level sensor for the injection system. The CID 510 is a benchtop unit, which means it is much smaller than the traditional CFR engine technology that typically required its own room.
