A techno-economic optimization model for aluminium electrolysis production

Abstract

The major factors affecting the profit of an enterprise are the price of the product, the price of raw materials and energy consumed, depreciation of fixed assets, labor cost, output and process consumptions, etc. In this paper, based on a cost-volume-profit (CVP) analysis method and the process techniques of aluminium production, a series of techno-economic analysis and optimization models for the production of the aluminium smelter enterprises are built. The models can be used for the aluminium smelters in various market situations to get the optimum technical parameters of production, which are necessary for obtaining the greatest economic benefit. Thus, it will guide the aluminium smelters in different market environment, according to their own conditions, to adopt different technical parameters of production to maximize the gains and to minimize the losses. We also have studied the optimization of potline current of a 300 kA aluminium smelter by the models as an example.
