Binary vapour-liquid equilibrium for systems of industrial importance.
(2015)Most industrial chemical engineering separation processes such as distillation, extraction, absorption and adsorption rely absolutely on accurate phase equilibrium data for effective design, optimization and simulation. ... -
Carbon dioxide capture methods for industrial sources.
(2010)In order to reduce the rate of climate change, particularly global warming, it is imperative that industries reduce their carbon dioxide (CO2) emissions. A promising solution of CO2 emission reduction is Carbon dioxide ... -
Carbon dioxide removal from coal power plants : a review of current capture techniques and an investigation of carbon dioxide absorption using hybrid solvents.
(2014)The aim of this project was to identify and assess all possible solutions to reduce carbon dioxide (CO2) emissions from coal power plants in South Africa, identify the most likely solution to be implemented industrially ... -
Carbon flow analysis in the South African forest and the forestry sector.
(2014)Material flow analysis is a systematic assessment of the flows and stocks of materials in a well-defined system. It is based on the law of the conservation of mass and this characteristic makes the material flow analysis ... -
Carbon flow analysis of the South African paper converting, paper recycling and end user stage of paper.
(2017)Abstract available in pdf. -
Catalytic hydrocracking of waste vegetable oil transition metal-based catalysts : selective production of jet fuel range alkanes.
(2015)The performance of transition metal-based catalysts on amorphous supports has been investigated for the high pressure (120 bar) hydrocracking of waste vegetable (cooking) oil in a fixed-bed tubular reactor between 400-450 ... -
CFD modelling of a novel clarifier design for use in sugar cane juice clarification.
(2008)The purpose of clarification in the sugar industry is to remove soluble, insoluble and colloidal matter from cane juice. Efficient clarification is required to produce high quality sugar and to prevent entrainment of solids ... -
Changes in the chemical composition of sugar cane (Saccharum officinarum) during storage.
(1973)An outline is given of the South African sugar industry, with particular emphasis on the unit operations which make up the industrial process for manufacturing sugar from cane. Current knowledge of the chemistry of ... -
Characterization of fluidization regimes by analysis of pressure fluctuations in gas-solid fluidized beds.
(2017)Fluidized beds are ranked as the top contacting method with the best overall benefits, and have been used over many years in several industrial applications. Literature indicates that pressure fluctuations are influenced ... -
Commissioning of a refrigerant test unit and assessing the performance of refrigerant blends.
(2017)This study has two major purposes; to commission and to demonstrate that a new refrigerant test rig can be used for investigating the performance of different refrigerants and refrigerant blends. The motivation for this ... -
Comparative refining characteristics of northern and southern hemisphere bleached softwood Kraft species.
(2009)An experiment was designed to test the hypothesis that each softwood pulp is unique and requires a specific, well defined mechanical treatment to derive its maximum strength potential. Three bleached softwood Kraft pulps ... -
A comparative study between the neutralizing capabilities of fly ash and green liquor dregs with acid mine drainage.
(2018)In South Africa, acid mine drainage (AMD) is a huge problem and arises when sulphide-bearing materials become exposed to oxygen and water. AMD formation is catalysed by mining and mineral extraction activities. The AMD ... -
A comparative study of contacting equipment for the recovery of copper from cupric sulphate solution.
(2005)Ion exchange for the recovery of metals from solutions is a well established process. It features significantly in terms of being able to recover valuable substances from what would otherwise be waste streams as well as ... -
A comparison between column and mechanical cell performance in platinum flotation.
(2012)Froth flotation has been used to concentrate minerals for over a century (Finch and Dobby, 1990) and it is essential for the economical recovery of metals which are present at low concentrations. The traditional flotation ... -
Comparison of an anaerobic baffled reactor and a completely mixed reactor : start-up and organic loading tests.
(2000)The aim of the investigation was to compare the performance of an anaerobic baffled reactor (ABR) with a completely mixed anaerobic reactor (CMAR). The ABR was operated with a hydraulic retention time (HRT) of 20 h ... -
The compostability and direct land application of paper mill sludge.
(2014)Mpact Ltd strives for the environmentally friendly disposal of waste material generated by 3 mills, Mill A, B and C. Mill C makes use of unbleached bagasse pulp to produce fluting and corrugated packaging paper, producing ... -
Delays and disruptions on construction projects within the public sector integrated project delivery system as an alternative.
(2017)The South African construction industry has earned a reputation for poor project delivery, particularly within the public sector. Successful project delivery has been identified as attaining the project objectives with ... -
Design and operation of a multistage pressurized fluidized bed combuster.
(1981)A three-stage Pressurized Fluidized Bed Combustor (PFBC) of principal dimensions, O,4Sm internal diameter by4m high was designed and fabricated to burn South African coals, with particular reference to coals unsuitable ...
