FAQs
What is clay treatment and how does it work?
Clay treatment uses specially designed clay elements to remove contaminants from fuels and other fluids. The clay works through an adsorption process where contaminants adhere to the surface of the clay material as the fluid passes through. Because the process relies on contact time between the fluid and the clay, controlling flow rate is critical to effective treatment.
Why is clay treatment used for jet fuel?
One of the most common applications of clay elements is removing surfactants from jet fuels. Surfactants can carry over from the refinery process or be introduced when jet fuel travels through multi-product pipelines, picking up contaminants such as corrosion inhibitors and gasoline additives.
What problems do surfactants cause in jet fuel?
Surfactants are particularly harmful because they will eventually disarm filter/separators, which are the equipment primarily designed to remove water from jet fuel. Once a filter/separator is compromised, water can pass through into the fuel system. By removing surfactants upstream, clay treatment protects these downstream filter/separators and maintains their effectiveness.
What is the recommended flow rate for jet fuel clay treatment?
A flow rate of approximately 6.5 gallons per minute (gpm) per 7″ x 18″ element is ideal for jet fuel treatment. Running at the correct flow rate ensures sufficient residence time, meaning the time the fuel spends in contact with the clay, which is essential for proper surfactant removal.
Why is residence time important in clay treatment?
Because clay removes contaminants through an adsorption (adhering) action, the fuel must spend enough time in contact with the clay surface for the process to work effectively. Too high a flow rate reduces contact time and can allow contaminants to pass through without being captured. Maintaining the recommended flow rate ensures optimal treatment performance.
What is the difference between adsorption and absorption in clay treatment?
Clay treatment uses adsorption, not absorption. In adsorption, contaminant molecules adhere to the outer surface of the clay material rather than being absorbed into it. This surface-binding mechanism is what makes flow rate and contact time so critical, as the contaminants need adequate time at the clay surface to bond and be retained.
Can clay elements be used for fuels other than jet fuel?
Yes. While jet fuel treatment is one of the most common applications, clay elements can be used across a range of fuel and fluid treatment scenarios where adsorptive removal of surfactants or other contaminants is required. Contact S.P. McLean Engineering to discuss your specific application and the appropriate element sizing and flow parameters.
How do I know when clay elements need to be replaced?
Clay elements have a finite adsorption capacity. Once the clay surface is saturated with contaminants, it can no longer effectively remove them. Monitoring downstream water separation performance and regular testing of treated fuel for surfactant levels are the best indicators. Element replacement intervals will vary depending on fuel contamination levels and throughput volume.
