According to a report in business publication, The Worldfolio, the researchers, in partnership with Qatar Water and Electricity Company (QEWC) - have commissioned a membrane distillation test
plant at QEWC's Ras Bou Fantas power and desalination facility.
The distillation test of gasoline aims to assess the volatility and performance characteristics as well as identify possible tampering.
The gasoline distillation test was performed according to ASTM D 86 standard , using a Engler flask with 125 ml of capacity, a distiller, a ASTM 7C/IP 5C thermometer with a range of -2 to 300[degrees]C and a graduated beaker.
The current legislation establishes compliance parameters for regular gasoline C, where in the distillation test the maximum temperature is 65[degrees]C for the first 10% distillate and 80[degrees]C for the 50% distillate.
Figure 1 shows the temperature values of the parameters obtained in the gasoline distillation test ([degrees]C), the residual percentage and the density (kg m-3).
Figure 4 shows the weight map of the parameter corresponding to the temperature of the first drop in the distillation test. In this map, most northern samples were located in the blue shade areas corresponding to temperature values ranging from 35 to 40[degrees]C, while the majority of eastern samples were in the yellow and red areas, corresponding to temperatures between 42 and 46 [degrees]C.
Other parameters of the distillation test, such as the 90% distillate, residue and final boiling point, were not important to the segmentation of samples, as can be seen by the weight maps shown in Figure 7.
