A critical analysis of emission quantification methods in the ferrochrome industry

Speaker:  Dr Kristy Nell, Research Fellow, Julius Kruttschnitt Mineral Research Centre

Abstract:  Estimation of greenhouse gas emissions is becoming important as companies are committing towards decarbonisation. Using the prescribed methods (standard guidelines) for estimating GHG emissions is often an over-generalisation and commonly not the most accurate way to quantify these emissions. It is possible to achieve more accurate estimations by following a detailed approach, e.g. through the construction of mass balances (MBs).

Bio:  Dr Kristy Nell (née Campbell) holds a bachelor's degree in Chemical Engineering from the North-West University (NWU), South Africa before continuing with postgrad studies at the CRCED (Centre for Research and Continued Engineering Development), NWU. Kristy's PhD focused on emission quantification in the ferrochrome industry. She worked as an engineer at ETA Operations for eight years gaining experience in government tax incentives and disincentives, energy savings quantification as well as energy and emissions budgeting and reporting. Industry exposure includes gold and platinum mines, ferrochrome smelters and oil and gas refineries. Kristy is a Certified Measurement and Verification Professional (CMVP). As a Research Fellow at JKMRC, Kristy will engage in carbon emission monitoring and quantification, and the evaluation of mitigation opportunities.
