Process filters used in hydrotreating processes. Hydrotreating is performed in an oil refinery to produce high quality fuels and feedstocks by reducing sulfur or nitrogen content, saturating olefins for stability improvement, or reducing aromatic content.  A Mott filter can be utilized to filter hydrotreater feed to prevent plugging and fouling of the catalyst fixed bed.  A Mott filter can also be utilized to filter the hydrotreater product to capture catalyst fines that may escape from the fixed bed.

Aggressive hydrotreating of residual fuel oil in an ebullated-bed hydrotreater / hydrocracker to remove sulfur is an option to meet the 2020 marine bunker fuel 0.5% sulfur limit.  A Mott filter can be used to filter the hydrotreater product and recycle any catalyst that escapes from the ebullated bed.
