Created specifically to address the unique chemical properties of ultra low sulphur diesel and biodiesel blends, the DieselPure USLD/Bio-blendlend filter has a two stage single pass design. In a single cycle, fuel is pushed through the internal core media to filter out large particulate (i.e. dirt, microbial growth, etc.) and free standing water. The fuel is then passed through the layers of pleated media to remove emulsified water and fine particulate. This completed process results in the capture of particulates down to 0.2 of a micron and 100% efficiency at removing emulsified water in ULSD and 96% in biodiesel as described below.
Emulsified Water in Diesel SAE J1488 ver. 2010 test results
DieselPure® filters were evaluated by SAE J1488 ver.2010 (fuel/water (emulsified) separation efficiency) 2010 test method using fuels with different interfacial tensions. SAE J1488 test method determines the ability of a fuel/water separator to remove emulsified water from fuel. The fuel water separation efficiency was determined using the upstream and downstream water concentrations in fuel samples withdrawn before and after the test filter element. The water concentrations were determined using Karl Fischer titration.
The filter evaluated during this program was identified as the DieselPure® filter. The DieselPure® filter element was evaluated using both ultra-low sulfur diesel fuel (ULSD), and ultra-low sulfur diesel fuel with monoolien (to simulate biodiesel).
The DieselPure® exhibited good water removal characteristics using ultra-low sulfur diesel ULSD. The DieselPure® filter was also tested using ultra-low sulfur diesel fuel containing monoolien. Monoolien is a pure compound composed of monoglycerides; it was added to ultra-low sulfur diesel fuel to simulate biodiesel or ultra low sulfur diesel fuel with low interface tension. The additization of ultra-low sulfur diesel fuel with monoolien was performed to target fuel with an interfacial tension of 15 mN/m. The DieselPure® filter was 96% efficient in separating water from fuel containing monoolien.
