High temperature fluid separations using ceramic membrane device

摘要

A high temperature ceramic membrane device for separation of fluids at high temperature, the device comprises: (a) a housing having: (i) an entrance for introducing fluids to the housing to be separated, (ii) an exit for removing fluids after being subjected to separation; (b) a plate mounted in one end of the housing, the plate having openings therein; (c) ceramic membrane comprised of porous ceramic tubes having a closed end and an open end, the tubes permeable by a fraction of the fluid to be removed from the fluid as filtrate and impermeable to a second fraction, the open end designed to remove the filtrate from the tube, the tubes mounted in the openings in the plate so that the closed end is projected into the housing and the open end is extended outside the housing for removing the filtrate; (d) a seal for sealing the plate in the housing; (e) insulation provided in the housing, the insulation means located adjacent the plate and surrounding the tubes projecting therethrough, the insulation adapted to insulate the hot fluid in the housing from the plate; and (f) cooling outside the housing adjacent the seal to maintain the seal at a relatively low temperature.
