OptiFlash Tag & Abel

The Tag & Abel methods are the latest additions to PAC’s OptiFlash. Our new analyzers can accurately detect flashpoints from -30°C to 120°C for petroleum products, solvents, chemicals, alcohols, foods and beverages. OptiFlash is fully compliant with leading global standards ASTM D56 and ISO 13736.
The numerous benefits include:

  • Significantly improved ease of operation
  • Easy cleaning
  • High safety standards
  • Proven performance and robustness
Cetane Ignition Delay

CEN has published, on August 5th, the Derived Cetane Number method EN 16715 which is based on PAC’s CID 510. All CEN member states will have adopted it on a national level by February 2016.CID 510 Cetane Ignition Delay

CEN TC19 has also started to work on an amendment of the EN 590 diesel specification which will include the addition of EN 16715 as alternate method to the engine.

ASTM D975, D6751 & D7467
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.

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.”

The ViscoPro 2100 enhances and improves the oscillating piston technology through improved performance, as well as ease of use and installation. Due to the ViscoPro 2100’s modular configuration, it is able to produce highly reliable viscosity results for numerous applications in the refinery, petrochemical, and coatings industries. With its new electronics design, the repeatability of the ViscoPro 2100’s measurements are improved by a factor of 2. Additionally, it has numerous hazardous area certifications, including FM, IECEX, and ATEX, and multiple communication protocols for measurements and diagnostics. “In the process environment, it is important to have real-time viscosity data you can trust. The ViscoPro 2100 utilizes the oscillating piston method, which has become the gold standard in small sample viscosity measurement with its patented sensor technology. It provides accurate viscosity data that correlates to laboratory results with no calibration drifts. With this viscometer, operations are able to tighten process control to ensure products meet specifications, ” said Daniel Benitez, PAC Vice-President of Process Analytics.
