Mott LSI filters excel in removing alumina-silica catalysts and other solids from FCC/RFCC main column bottom slurry feeds. Featuring online, clean-in-place backwashing and automated process control, these filters consistently achieve less than 100 ppm total suspended solids in filtrate quality. This ensures the filtered oil is ideal for blending or as a sellable product. The flexibility of Mott’s system allows backwashed slurry to be recycled to the riser, concentrated, or disposed of as per refinery needs. With installations in over 20 filters across five continents in both FCC and RFCC slurry oil applications, Mott LSI filters are a proven solution in the refining industry.

What are FCC slurry oil filters?

FCC slurry oil filters, a key product in Mott’s lineup, are essential in refining operations for filtering Fluid Catalytic Cracking (FCC) slurry oil. These filters are designed to remove fine particulates, including alumina-silica catalysts, from the slurry oil that is produced during the FCC process. Mott’s advanced FCC slurry oil filters stand out for their efficiency, achieving filtrate quality with less than 100 ppm of total suspended solids. This ensures that the filtered oil meets the high standards required for blending or sale, making these filters a critical component in optimizing refinery output and profitability.


Q: What is FCC/RFCC slurry?

A: FCC (Fluid Catalytic Cracking) and RFCC (Resid Fluid Catalytic Cracking) slurry is a by-product of the oil refining process where heavy petroleum fractions are broken down into lighter, more valuable products like gasoline and diesel. This slurry is a mixture of oil, catalyst particles, and other sediments that result from the cracking process.

Q: How are FCC/RFCC slurry filters used in the refining process?

A: FCC/RFCC slurry filters are used to remove solid contaminants and catalyst particles from the slurry oil produced in the FCC/RFCC process. These filters ensure that the final product meets quality specifications by reducing total suspended solids to very low levels, typically below 100 ppm. This filtration step is crucial for protecting downstream equipment and ensuring the quality of the end products.

Q: What are the benefits of using FCC/RFCC slurry oil filters in refineries?

A: The benefits of using FCC/RFCC slurry oil filters in refineries include improved product quality, protection of downstream processing units, enhanced operational efficiency, and reduced maintenance costs. By effectively removing contaminants, these filters ensure that the oil derived from the slurry can be used efficiently, either for blending purposes or as a marketable product.

Q: Can FCC/RFCC slurry oil filters be customized for specific refinery needs?

A: Yes, FCC/RFCC slurry oil filters can be customized to meet specific requirements of different refineries. Factors like the composition of the slurry, flow rate, and specific filtration needs are considered in the customization process. This ensures optimal performance and efficiency, tailored to each refinery’s unique operational conditions.
