Title:
METHOD AND APPARATUS FOR CONDENSING METAL VAPOURS USING A NOZZLE AND A MOLTEN COLLECTOR
Document Type and Number:
WIPO Patent Application WO/2011/051674
Kind Code:
A3
Abstract:
The present invention concerns the condensing of vapour phase compounds or elements, typically metals such as magnesium, obtained by reduction processes. These include metallothermic and carbothermic processes. There is described a method for condensing a metal vapour comprising: providing a gas stream comprising the vapour, passing the gas stream into a condensing chamber via a nozzle which has an upstream converging configuration and a downstream diverging configuration so that the metal vapour accelerates into the nozzle and expands and cools on exiting the nozzle thereby inducing the vapour to condense to form a beam of liquid droplets or solid particles in the condensing chamber, wherein the beam of droplets or particles is directed to impinge onto a liquid collection medium surface. Apparatus for performing the method is also described.
