Chloride Content in Bioethanol
|
In times of skyrocketing gasoline prices and climate changes, ethanol fuel is a promising renewable high-octane vehicular fuel.
A major drawback, however, is the contamination with inorganic salt ions such as chloride, nitrate and sulfate. These ions can affect engine performance because precipitating salts clog filters and fuel injector nozzles. Furthermore, these ions enhance corrosion in the vehicle components in contact with the fuel.
Hence there is an urgent need for standards defining quality specifications and test methods.
For chloride two different standards define two different methods:
- Determining the chloride content according to
ASTM D 512 by titration
- Determining the chloride content according to
ASTM D 7319 by ion chromatography
