the HDS reactor at a CSCC plant. It has replaced both the front-end basket filter and cartridge filter, as well as elimi - nated use of RTM packings that can only remove large solid particles. Eliminating RTMs also allows more room for an expanded catalyst bed. The reactor WABT increased only 1ºC (essentially no change) and maintained its initial activity during five years of smooth operations. Meanwhile, the pressure drop caused by plugging in both the front-end heat exchanger and HDS reactor is essentially unchanged during the same period. The filter is capable of removing most of the larger par - ticles in the feed stream, allowing only a small quantity of tiny particles with sizes ranging from 6.6 to 22.5 nm (mostly around 13 nm [0.013 µm]) and from 260 to 1,000 nm (mostly around 400 nm [0.4 µm]) into the HDS rector. The PSD curve of the filter outlet stream suggests that particles with a size range of 6.6-22.5 nm (or <30 nm) pass through the HDS reactor freely without causing reac - tor plugging problems. This is because the PSD curve of the filter outlet stream in this particle size range closely matches the PSD curve of the HDS reactor liquid product (4.4-29.5 nm). The quantity of particles with sizes from 260 to 1,000 nm (mostly around 400 nm [0.4 µm]) in the filter outlet stream is so small that it did not cause many pressure drop problems in the reactor for five years of operation.
