The exchanger is made from a number of tubes sealingly connected to a pipe plate which is further connected to an enclosure. The pipe plate is realized by positioning enclosure and tubes in a mould and pouring a ceramic slurry which is subsequently sintered.

Method for producing an exchanger and exchanger

A method for producing hollow fibrous membranes includes the steps of mixing a ceramic powder with a binder to form a paste having a sufficient viscosity to be extruded without heating, characterized in that said binder is a binder dissolved in water or another simple solvent or a thermosetting binder or an inorganic binder or a combination of said binders; extruding the paste to the form of hollow fibers by means of a spinneret; supporting the hollow fibers leaving the spinneret on a roller conveyor comprising a pair of rollers which rotate in opposite directions away from each other where the fibers contact the rollers; and sintering the hollow fibers. These membranes are used for microfiltration, ultrafiltration or gas separation. The fibrous membranes have an external diameter of 0.1-3 mm and a wall thickness of 10-500 &mgr;m.

Method for producing a high temperature resistant exchanger. The exchanger is made from a number of tubes sealingly connected to a pipe plate which is further connected to an enclosure. The pipe plate is realised by positioning enclosure and tubes in a mould and pouring a ceramic slurry which is subsequently sintered.
