Indirect carbothermal reduction of alumina for the production of aluminium has been claimed to be better compared to the existing Hall-Heroult process in-terms of energy usage, generation of perfluorocarbons and overall greenhouse gas emission. In the process, alumina is reduced to an intermediate compound which is then further reduced to Al. It has been shown from the previous thermodynamic study by the authors that high conversion of alumina can be obtained if it is reduced to Al-chloride, Al-nitride or Al-sulphide. This paper deals with detailed systematic thermodynamic analysis of the process through carbosulphidation route, where alumina is first reduced to …

With the proliferation of large, disturbing installations (loads and distribution generators) connected to public low voltage networks, managing the harmonic voltage levels in the network has become a key concern to distribution network service providers (DNSPs). Therefore, it is important that DNSPs limit the harmonic current emission by individual installations. This paper reviews a number of methodologies that exist in the current technical literature in relation to the assessment of harmonic current emission limits for disturbing installations connected to the public LV network. Application of these methodologies is demonstrated through a case study on a test network. The study shows …
