Title:
LTFT CATALYST FINES REMOVAL
Document Type and Number:
WIPO Patent Application WO/2016/118982
Kind Code:
A3
Abstract:
The invention provides a method, stage and plant for removing LTFT catalyst fines and/or organometallic catalyst compounds from of LTFT wax, downstream from the LTFT reactor. The method includes at least one stage having the steps of causing a differential pressure across a filter element; causing high mechanical shearing and/or centrifugal forces along and/or away from the surface of the filter on the high pressure side of the filter to cause the particles to be continuously removed from the filter surface; and wherein the differential pressure is selected to be sufficient to force flow of the wax across the filter to cause filtration.
