The complexity of the refining business keeps increasing, making it more essential to generate results in a timely fashion. The latest version of PAC’s online distillation analyzer, MicroDist, offers distillation and density analysis in a single instrument. As a result, the number of suitable applications has been expanded to include calculating the Cetane index for diesel fuel process streams and intermediate blends according to ASTM D4737 and D976. Results are generated in fewer than 10 minutes, allowing refineries to maximize production with cut point optimization of the crude oil. PAC L.P.
