PAC Developed the Newly Released ASTM D7668 for the Herzog CID 510

PAC developed the newly released ASTM D7668 'Standard Test Method for Determination of Derived Cetane Number (DCN) of Diesel Fuel Oils - Ignition Delay and Combustion Delay Using a Constant Volume Combustion Chamber Method', for the PAC Herzog CID 510. The CID 510 provides highly accurate Derived Cetane Number (DCN) analysis for diesel fuels in the complete DCN range from 15 to 100 with excellent correlation to the CFR Engine.

As part of the method development process, ASTM and the Energy Institute conducted an extensive interlaboratoy 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 CFR Engine and the DCN determined with the CID 510. The precision of the CID 510 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).

The excellent precision and correlation of this technology allows refineries to run their process closer to the specification limit for the cetane number which leads to significant cost savings due to reducing the amount of cetane improver needed. For a refinery producing 100,000 barrels of Diesel per day, operating at one 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, including:

• Improved ease of use – fully automated measurement and calibration with one button operation
• High safety standards – the instrument is fully enclosed with over temperature and over pressure protection and includes a built in fire monitoring and extinguishing system
• Reduced maintenance – with soot less combustion, cleaning of the test chamber is not needed; the high calibration stability does not require operators to do  weekly or daily calibration
• Reduced space – it is a bench-top model that is approximately 70% smaller than the CFR Engine.
