Magnetic separation combined with dynamic settling for fischer-tropsch processes

摘要

A system for separating particulate from a fluid stream having an inlet solids content, the system comprising: a magnetic dynamic settling vessel comprising at least one magnetic field inside the vessel and/or one magnetized component; at least one inlet for introduction of the fluid stream having a starting solids content; at least one exit for a stream comprising a solids content not greater than the inlet solids content; at least one exit for a fluid stream comprising a solids content not less than the inlet solids content; and a vertical feed conduit extending at least 70% of the distance from the at least one fluid inlet to the at least one exit for a fluid stream comprising a solids content not less than the inlet solids content. A method for separating particulate from a fluid stream having an inlet solids content is also provided.

1. A method for separating solid particles from a fluid stream having an inlet solids content, the method comprising:
introducing the fluid stream into a magnetic dynamic settler vessel, wherein the inlet solids content is greater than 5000 ppm by weight, and wherein the magnetic dynamic settler vessel comprises at least one magnetic field within the vessel, at least one fluid inlet for introduction of the fluid stream having the inlet solids content, at least one exit for a liquid product stream comprising a solids content less than the inlet solids content, at least one exit for a fluid stream comprising a solids content greater than the inlet solids content, and a vertical feed conduit extending at least 70% of the distance from the at least one fluid inlet to the at least one exit for a fluid stream comprising a solids content greater than the inlet solids content, wherein the magnetic dynamic settler vessel comprises no other interior physical component and wherein the at least one magnetic field is directed such that the solids agglomerate substantially vertically; removing from the magnetic dynamic settler vessel at least one liquid product stream comprising a solids content less than the inlet solids content; and continuously removing from the magnetic dynamic settler vessel at least one stream comprising a solids content greater than the inlet solids content.
