Abstract: Methods and systems for controlling operating conditions of electrolytic cells are provided, particularly aluminum electrolytic cells. The method may includes the steps of measuring offgas temperature from the electrolytic cell, comparing the measured offgas temperature to a target offgas temperature, and completing a predetermined action in response to the comparing step. The predetermined action may include one or more of changing a feed rate of feed materials supplied to the electrolytic cell or inspecting a crust of the electrolytic cell for an undesired condition, such as a crust hole. The system may include an electrolytic cell adapted to contain a molten metal mixture, a hopper adapted to provide feed material to the electrolytic cell, a hood adapted to contain offgas from the electrolytic cell, an exhaust duct interconnected to the hood and containing a thermocouple for measuring offgas temperature, and a control panel for receiving temperature measurements from the thermocouple.
