A method and an apparatus for reducing the corrosion of a condenser in carbide derived carbons (CDC) production where cooling/quenching of a gaseous stream metal or metalloid halide is performed by direct contact of gaseous stream with liquid cooling agent before condenser, without utilizing a heat exchanger for the temperature range above 300° C., while keeping purity of gaseous stream of metal or metalloid halide constant. The apparatus comprises a reactor for carbide to carbon conversion and a condenser for collecting the by-produced metal- or metalloid chloride, and a cooling unit comprising a tank of liquid cooling agent. Temperature of the gas stream entering the condenser is reduced by heat absorbed in vaporization of a liquid metal- or metalloid halide introduced from the tank of liquid cooling agent through by supply pump, through the supply flow valve into the gaseous stream at the exit of the reactor.
