Abstract:
In combination with a gasification reactor which produces a reaction slurry, a dynamic settler for removing catalyst particles from wax in the reaction slurry, said settler comprisinga vessel having a wall defining a chamber having an upper end and a lower end, an inlet pipe entering the vessel at said upper end and defining an annular volume between the vessel wall and the inlet pipe, a slurry recirculation pipe attached to said vessel and communicating with the chamber at said lower end, a multichannel baffle within said annular volume and fully occupying said annular volume, and a wax removal pipe communicating with said annular volume above said baffle, said baffle dividing said annular volume into plural channels, the maximum cross-sectional dimension of said channels being sufficiently small as to minimize natural convection flow so as to promote settling of particles from the slurry.
