Systems and methods for controlling heat loss from an electrolytic cell in a smelting process using an adjustable fluid passage to control the heat loss from a preferred area of the electrolytic cell side walls based on operating conditions in the electrolytic cell, and to direct the waste heat from the electrolytic cell side walls back into the electrolytic cell.

An apparatus and a method are useful for removing pollutants from process effluent gas produced by an electrolytic cell used in an aluminum production plant to produce aluminum. The apparatus and method use a flow control device to control alumina supply to an electrolytic cell and to a dry scrubber contact reactor.

Integrated systems may be characterized by: (a) an aluminum production subsystem comprising an aluminum-producing electrolysis cell configured to electrolytically produce aluminum metal from an aluminum compound; and (b) a carbon dioxide reduction subsystem comprising a carbon dioxide electrolyzer, where the carbon dioxide reduction subsystem is configured to receive carbon dioxide produced by the aluminum production subsystem and provide the carbon dioxide to the carbon dioxide electrolyzer for reduction to a carbon-containing product.
