Recently we were asked to assist a customer in delivering higher quality diesel fuel to his end-users. In order to accurately gauge the level of fuel quality required, we felt it was imperative to utilize a more precise method of testing than the standard ASTM specification. To ensure test results were as detailed as possible, we measured the fuel quality with the ISO cleanliness code 4406:1999.

Our goal was not only to establish “new” fuel quality, but also to document the increase in quality after the fuel was passed through high-efficiency filtration media. To provide data in a timely and cost effective manner we chose to analyze the fuel quality on a smaller scale with a filtration test stand. The fuel sample that was provided in a 55-gallon drum was transferred into a clean, empty drum using our 1-GPM Spin-On Filter Panel (SFP). For this process, we equipped the SFP with a single absolute rated 1-micron, micro-glass filter. This fluid transfer package, which includes quick-disconnect hoses/wands and desiccant breathers, ensures that any ingress of contamination is minimized throughout the fluid transfer process.
Using a HIAC PODS (Portable Oil Diagnostic System) Laser Particle Counter, we first established an ISO code baseline for “new” diesel fuel. An in-line sample port located before the filter allowed us to accurately establish a baseline code level of 18/16/12. A sample port located after the filter provided an ISO reading of 13/10/6 after only a single pass of filtration. The second and final pass through the filter lowered the contaminant level even further to achieve an ISO cleanliness code of 11/7/5!
Based upon these results we determined that just one pass through our high-efficiency 1-micron filters will achieve our customer’s required fuel quality. When a larger version of this filtration system is implemented with a full-scale pipeline filter vessel, our customer will have the ability to consistently deliver super-clean fuel to his end-users, which will be of even higher quality than the ASTM standard!
