A method and apparatus is described that uses a device that presents a surface of a dielectric material to a flowing or circulating fluid that results in charge being created at a boundary layer of the dielectric where it contacts the fluid by ion exchange and charging of compounds, for example insoluble dielectric particles such as colloids, and using at least one control impedance to control an impressed current in the fluid caused by the fluid flowing through the device and to cause suspended particles in the fluid to be charged, whereby the charge of the suspended particles is then neutralised causing coagulation of the particles as suspended insoluble particles.

A METHOD FOR COOLING/QUENCHING OF HIGH-TEMPERATURE GASEOUS STREAM OF METAL- OR METALLOID HALIDES IN CARBIDE DERIVED CARBON PRODUCTION
20220040660 · 2022-02-10 ·

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.
