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 ... -
The design of two apparati to measure solid-liquid and liquid-liquid equilibria data.
(2010)Two new apparati have been developed to measure solid-liquid and liquid-liquid equilibria via a synthetic visual method by determination of thermal signatures. One apparatus adopts a technique of using Peltier modules for ... -
Determination of activity coefficients at infinite dilution using the inert gas stripping technique.
(2008)The determination of limiting activity coefficients in liquid mixtures has become an important tool in chemical engineering. It has been investigated intensively during the past in order to find new alternatives and ... -
Determination of phase equilibria for long-chain linear hydrocarbons by Monte Carlo simulation.
(2005)The focus of this study was to determine the coexistence phase equilibria for three groups of long-chain linear hydrocarbons (n-alkanes, 1-alkenes and 1-alcohols) using Monte Carlo simulation. Three common transferable ... -
Development amd implementation of a real-time observer model for mineral processing circuits.
(2004)Mineral processing plan ts, such as LONMIN's Eastern Platinum B-stream, typically have few on-line measurements, and key measures of performance such as grade only become available after samples have been analysed in the ... -
The development and application of combined water and materials pinch analysis to a chlor-alkali plant.
(1989)Pinch Analysis, in the broadest sense, is concerned with the optimal use of resources (material or energy) in a multi-process system. Pinch Analysis based techniques have emerged for water systems over the past decade. A ... -
Development and modelling of a semi-batch flotation apparatus.
(2008)When designing or optimizing flotation circuits in mineral processing plants, it is necessary to have accurate values of the flotation kinetics to ensure the correct mass pulls and material balances on the plant. Previous ... -
Development and verification of an Aspen Plus® model of a sugarcane biorefinery.
(2018)This dissertation describes a steady-state mass and energy balance model of a raw sugar mill which has been developed using the Aspen Plus® software. The Aspen Plus® model was designed to replicate an existing MATLAB model ... -
Development of a continuous process for the production of hexafluoropropyl methyl ether.
(2015)Partially fluorinated dialkyl ethers are valuable intermediates for organofluorine syntheses. These compounds can be used for the preparation of perfluoroacrylic acids or the anhydrides, amides and esters thereof. They ... -
Development of a dynamic still for measuring low pressure vapour-liquid-liquid equilibria : systems of partial liquid miscibility.
(2005)The dynamic still originally designed by Raal (Raal and Muhlbauer [1998]) has been transformed into a valuable still that can now be used for measuring both low pressure vapour-liquid equilibria (VLE) for systems that are ... -
Development of a group contribution method for the prediction of normal boiling points of non-electrolyte organic compounds.
(2004)Physical properties are fundamental to all chemical, biochemical and environmental industries. One of these properties is the normal boiling point of a compound. However, experimental values in literature are quite limited ... -
The development of a hybrid activity coefficient model utilizing the solution of groups concept.
(2011)During the course of this thesis the UNIFAC method (group-based method) was regressed to individual Px(T) binary datasets, and the results are compared to the regression results using the Wilson, NRTL, and UNIQUAC equations ... -
Development of a model of the aerobic membrane bioreactor treating Illovo wastewater.
(2014)The Membrane Bioreactor (MBR) at Sezela, KwaZulu-Natal treats a process effluent emanating from a sugar industry by-products plant. Depending primarily on the effluent feed rate to the MBR as well as other less significant ... -
Development of a performance indicator model for carbon capture applications.
(2017)Abstract available in PDF file. -
Development of a pilot scale black liquor gasifier.
(2011-05-04)The use of black liquor gasification as an alternative to conventional chemical and energy recovery systems for spent liquors is an area of particular interest to the pulp and paper industry. The motivation to explore this ... -
Development of a thermodynamic model for the purification of 1-hexene.
(2007)The South African based petrochemical company, SASOL, operates three large plants for the recovery and purification of the chemical 1-hexene. The thermodynamic models available in commercial simulation packages fail to ... -
The development of a three-phase filtration cell
(2010)The chemical and process industries rely largely on filtration processes to separate solid-liquid process -
The development of a weighted directed graph model for dynamic systems and application of Dijkstra’s algorithm to solve optimal control problems.
