Economically efficient cooling of the exhaust gas from aluminium smelting process- overview and proposals
Aluminum smelting is a high energy consuming industrial process. The process generates a large amount of the heat that leaves through the exhaust gas. The exhaust gas must be scrubbed of its contaminants before releasing to the atmosphere at the gas treatment unit exit. The scrubbing process is more effective if this gas is cooled before entering the gas treatment unit. There are different solutions to cool down gases upstream of the GTCs. All gas cooling technologies have their own advantages and disadvantages. The main objective of this project is to provide an exhaustive analysis of literature with an indication of some potential options for gas cooling to find the cheapest way to reduce the temperature of the gas by 5-10?C.
