Author Posts February 6, 2014 at 1:54 pm #11650 Elyor RoziboyevMember Folks, Just a quick advisory that we participated in the startup of a large FSS system last month. The Mott Corporation system was designed without the use of internal manifolds, which allowed for a smaller filter vessel and therefore, lower installed cost. The reason for the installation is to limit particulate emissions downstream of the Third Stage Separator (TSS). Mott also have over 30 systems installed successfully in FCC Slurry Oil. Please let me know if we can help you.
