Quick Answer
To remove water from stored diesel, consider using a combination of coalescing filters and drying agents, or employing a specialized desiccant like silica gel or activated alumina, which can absorb up to 1/3 of its weight in water.
Removing Water with Coalescing Filters
Coalescing filters are a common and effective method for removing water from diesel. These filters consist of a specialized media that causes water droplets to merge into larger droplets, which can then be easily separated from the diesel. When choosing a coalescing filter, look for one with a high oil capacity, such as the 10-micron filter, which can handle up to 10 gallons of fuel per minute.
Using Desiccants for Water Removal
Desiccants like silica gel or activated alumina are highly effective at absorbing water from diesel. These materials can absorb up to 1/3 of their weight in water, making them ideal for removing small amounts of moisture from stored diesel. To use a desiccant, simply place the material in a container with the diesel and let it sit for several hours or overnight.
Important Safety Considerations
When removing water from stored diesel, it’s essential to use proper safety precautions to avoid accidents and contamination. Always use a well-ventilated area and avoid smoking or using open flames. Additionally, make sure to follow the manufacturer’s instructions for any equipment or materials used in the process.
