Book excerpt: The symposium brings together papers by industrial users of oxygen, major oxygen producers, engineering firms and leading experts in the field. It covers recent development in oxygen technology - both in application and technology. Both pyrometallurgical and hydrometallurgical applications are discussed, and O2 production technologies feature the cryogenic process together with several alternative novel methods. Established and new emerging processes are featured, and increased process efficiencies, higher throughputs and reduced energy consumption are among the objectives of the symposium.
