HANDLING OF BY-PRODUCT GASES FROM A SILICON FURNACE What is disclosed is an improvement in a process for the carbothermic reduction of silicon dioxide to form silicon, the improvement comprising (a) contacting the by-produced gases from the silicon furnace with a liquified hydrocarbon-containing gas to cool the by-produced gases and to cause silicon-containing materials to completely condense and to form agglomerated solids; (b) removing the agglomerated, solid materials from the gases, and (c) recovering energy value from the solids-free by-produced gases. |
