Portable fuel compatibility testing for safer blending and reliable engine performance
Regular monitoring of density of the delivered oil provides reassurance about the conformity of oil quality and its cost. Whereas verification of stability/ compatibility of different heavy fuel oils is regarded as an essential measure for ensuring continuous normal operation of the engine system. These important oil properties can be determined directly on-site with the help of the test device COMPA DENS CHECK in easy and quick test procedures.
Onboard a ship, the compatibility of marine fuels, including residual and distillate fuels, can be measured well with this type of mobile test.
The compatibility test test method used follows ASTM D 4740-04 (2014).
Regular monitoring of the density of the oil supplied makes it possible to confirm the conformity of the oil quality and its cost. Checking the stability/compatibility of various heavy oils (low and high sulphur) and marine gas oil (MGO) is important for the normal continuous operation of the engine system. In a simple and quick test procedure, these important oil properties can be determined directly on site with the help of this test device.
The early detection of the miscibility of fuels with the aid of mobile test systems is a very good aid for daily on-board practice.

To measure the density, it is necessary to fill the glass tube with the oil sample and place it in the heating bath. As soon as the temperature of 50°C is reached, the density can be determined by using the appropriate hydrometer. The density value is automatically converted to the standard temperature of 15°C. Stability and compatibility of heavy fuel oils are measured with identical test runs. Two mixed oil samples (or only one sample for the stability determination) are heated to 95°C in a heating bath. A drop of the heated oil is applied to the chromotographic paper and analysed as soon as it has dried out.
The applied test method with the test kit follows ASTM D 4740-04 (2014).
