Abstract:

A laboratory method and apparatus were developed for the evaluation of the water separation properties of fuels and fuel-additive combinations. The instrument, known as the Water Separometer, produces a water-in-oil emulsion mechanically, meters this emulsion through a cell containing standardized fiberglass coalescer disks, and analyzes the effluent for entrained water by light transmission. The relative ease of water removal from a given fuel is rated by averaging light transmission values obtained during a series of scheduled flow rates. This rating is known as the Water Separation Index WSI. Variables affecting the performance of the method which have been studied include coalescer media, water-to-fuel ratio, operating pressure, temperature, and cleanup procedure. Cooperative studies with other laboratories have shown the method to be satisfactory with respect to both repeatability and reproducibility. Comparison of data indicated that a good correlation exists between the developed laboratory method and the larger systems. Author
