A target-based performance tracker for mine energy monitoring
(North-West University (South Africa), 2021)Software systems play a major role in the day-to-day operation of deep-level mines. These systems range from quantifying production and energy use to monitoring seismic activity. As deep-level mines expand to reach more ... -
Tariff structure selection for optimal electricity cost savings on a process plant
(North-West University (South Africa), Potchefstroom Campus, 2016)South Africa's electricity grid is currently under strain due to the high demand of electricity. This strain on the grid has resulted in the increase of electricity costs that has put financial pressure on consumers. In ... -
Technical evaluation criteria for centrifugal pump selection in the petrochemical industry
(North-West University (South Africa)., 2022)Many users are faced with the difficulty of technically evaluating and selecting the most appropriate centrifugal pump for the specific operating condition, due to its required specialised field within mechanical ... -
Technical evaluation of the copper chloride water splitting cycle
(North-West University, 2011)The global energy sector is facing a crisis caused by the increasing demand for energy. Non-renewable energy sources, such as fossil fuels produce greenhouse gases that are largely blamed for climate change. The Kyoto ... -
Technician level needs and skills development guidelines for the South African nuclear energy industry
(North-West University, 2012)The increasing demand for electrical energy to bring about development and social change has brought about renewed interest in the use of nuclear power as one of the sources of electrical energy. The nuclear power industry ... -
Techno economic viability of desalination processes in South Africa
(North-West University, 2011)The provision of fresh water to sustain current economic development and the ever increasing population is one of the world?s greatest challenges and will become increasingly acute in the immediate future. South Africa is ... -
Techno-economic analysis for construction and operation of a fleet of nuclear power plants in South Africa as proposed by the IRP 2010
(North-West University (South Africa), Potchefstroom Campus, 2018)The South African Government has prioritized industrialization and infrastructure investment to ensure electricity supply and distribution to its people and industries. In order to realize this, the Government intends ... -
Techno-economic analysis of the 100 MW Potchefstroom experimental pebble bed reactor plant
(North-West University, 2009)Electricity is directly linked to the economy of a country: when electricity is limited and the price for electricity is very high, the high electricity price will have a negative influence on the economy of the country. ... -
Techno-economic application of modular air cooling units for deep level mining at Mponeng
(North-West University, 2008)As mining explores greater depths beyond 4000m at Mponeng Mine the challenges of obtaining suitable working environments and complying with regulations becomes significant. These depths mean a considerable increase in the ... -
A techno-economic appraisal of renewable energy in remote, off grid locations in Nigeria : Obudu ranch as a case study
(North-West University, 2008)Energy is central to economic development. It has been established that there is a clear correlation between energy consumption and living standards. Nigeria is a country of very industrious and enterprising people. However, ... -
A techno-economic evaluation of a waste-to-energy grate incineration power plant for a small South African city
(North-West University (South Africa), Potchefstroom Campus, 2016)South Africa is currently facing power shortages due to an increased demand, a failure to invest in additional capacity and insufficient maintenance. Likewise, over the years, municipal solid waste (MSW) generation and ... -
Techno-economic evaluation of demilitarized TiCl₄ recycling processes
(North-West University (South Africa), 2019)Demilitarization has become a critical field of study in South Africa over the last decade. With the focus of reusing or recycling all components with potential values, hazardous environmental impacts can be drastically ... -
Techno-economic evaluation of the hybrid sulphur chemical water splitting (HyS) process
(North-West University, 2010)The constantly growing demand for energy and the consequent depletion of fossil fuels have led to a drive for energy that is environmentally friendly, efficient and sustainable. A viable source with the most potential ... -
A techno-economic evaluation of the production of hard coking coal from Tshikondeni coal discards
(North-West University (South Africa) , Potchefstroom Campus, 2016)Tshikondeni Coal, operated by Exxaro Resources Limited on behalf of the owners, ArcelorMittal South Africa, is currently the only operational hard coking coal mine in South Africa. Therefore the yield from the plant needs ... -
Techno-economic optimisation methodology for HTGR balance of plant systems
(North-West University, 2010)The nuclear industry lacks a well documented, systematic procedure defining the requirements for power plant cycle selection and optimisation. A generic technoeconomic optimisation methodology is therefore proposed that ... -
