Abstract:
A method for removing catalyst particles from wax in a reaction slurry produced in a Fischer-Tropsch reactor, said method comprising steps ofpassing said slurry through a 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 under process conditions which minimize natural flows in the baffle so as to promote settling of particles from the slurry.
