<p>Apparatus and method for processing waste gas comprising carbon monoxide, comprises a humidifier 11 for humidifying the waste gas, a water shift reactor 15 arranged to receive the humidified waste gas and to produce a reaction product comprising at least carbon dioxide and hydrogen, a cooler 16 arranged to cool the reaction product and a separator arranged at least partially to separate the carbon dioxide and hydrogen from the cooled reaction product. Preferably a particulate filter 18 such as a cyclone, semi-porous membrane, electrostatic precipitator, fabric filter or ceramic filter is also provided to remove particulate material from waste gas. Advantageously the apparatus is used to process by-product or waste gases exiting carbon-based industrial processes such as a blast furnace used to produce iron and steel.</p> |
