Summary

The use of low purity oxygen is attractive for the latest technology available for the production of non-ferrous metals. In these applications it allows improvements in productivity, fuel efficiency and helps to protect the environment, as the total throughput of gas in the plants can be reduced. The penalty for use of oxygen is the additional capital expenditure (CAPEX) for the oxygen plant plus the additional energy consumption (OPEX) for operating the plant. The presentation shows how the topology and the parameters of the process can be chosen so that both CAPEX and OPEX can be minimised. It summarises the state of the art technology for cryogenic oxygen recovery processes and then introduces an advanced approach to provide low purity oxygen for smelter applications. The physical background and mechanisms of the process cycle definition under the given boundary conditions is described, as well as the technical parameters for selection of machinery and equipment.
