Analysis and modelling of mining induced seismicity

Bredenkamp, Ben (Stellenbosch : University of Stellenbosch, 2006-12)

Earthquakes and other seismic events are known to have catastrophic effects on people and property. These large-scale events are almost always preceded by smallerscale seismic events called precursors, such as tremors ...
Analysis of process data with singular spectrum methods

Barkhuizen, Marlize (Stellenbosch : University of Stellenbosch, 2003-12)

ENGLISH ABSTRACT: The analysis of process data obtained from chemical and metallurgical engineering systems is a crucial aspect of the operating of any process, as information extracted from the data is used for control ...
Assessment of the capabilities of two polar sPC-SAFT terms through application to measured ketone-alkane phase equilibria data

Cripwell, Jamie Theo (Stellenbosch : Stellenbosch University, 2014-04)

ENGLISH ABSTRACT: Thermodynamic models have been investigated extensively since Johannes van der Waals first devised a mathematical relation capable of predicting both vapour and liquid phases for a mixture at equilibrium. ...
Bacterial production of antimicrobial biosurfactants

Ballot, Francis (Stellenbosch : University of Stellenbosch, 2009-03)

Surfactants are compounds that reduce interfacial surface tension, resulting in detergency, emulsifying, foaming and dispersing properties. Surfactants produced via biochemical processes (biosurfactants) form a niche market ...
Bacterial production of antimicrobial biosurfactants by Bacillus subtilis.

Bence, Keenan (Stellenbosch : Stellenbosch University, 2011-12)

ENGLISH ABSTRACT: Biosurfactants are microbially produced molecules that show excellent surface-active properties. Bacillus subtilis ATCC 21332 produces the biosurfactant, surfactin, which exhibits antimicrobial activity ...
The bio-disposal of lignocellulose substances with activated sludge

Qi, Bing Cui (Stellenbosch : Stellenbosch University, 2001-03)

ENGLISH ABSTRACT: Lignocellulose is the principal form of biomass in the biosphere and therefore the predominant renewable source in the environment. However, owing to the chemical and structural complexity of lignocellulose ...
Biochar from vacuum pyrolysis of agricultural residues : characterisation and its applications.

Uras, Umit (Stellenbosch : Stellenbosch University, 2011-12)

ENGLISH ABSTRACT: According to recent studies, biochar has the potential to improve soil fertility, mitigate climate change, reduce off-site pollution and assist in managing wastes. The application of biochar to soil is ...
Bioconversion of alkylbenzenes by Yarrowia lipolytica

Lind, Aingy Chantel (Stellenbosch : University of Stellenbosch, 2009-03)

The abundance of alkane by-products formed in South Africa presents a feedstock opportunity for the production of a wide range of commercially important products, such as long-chain dioic acids and alcohols. These compounds ...
Biodiesel analytical development and characterisation.

Prah, Ebenezer (Stellenbosch : University of Stellenbosch, 2010-03)

ENGLISH ABSTRACT: Development of analytical methods to characterise biodiesel has become central to the overall success of the marketing of biodiesel fuel. In this regard, different bodies including the American Society ...

Catalytic distillation : design and application of a catalytic distillation column

Nieuwoudt, Josias Jakobus (Jako) (Stellenbosch : University of Stellenbosch, 2005-12)

Catalytic Distillation (CD) is a hybrid technology that utilizes the dynamics of si- multaneous reaction and separation in a single process unit to achieve a more compact, economical, efficient and optimized process ...
CFD analysis of solid-liquid-gas interactions in flotation vessels

Karimi, Mohsen (Stellenbosch : Stellenbosch University, 2014-04)

ENGLISH ABSTRACT: A Computational Fluid Dynamics (CFD) model was developed for the prediction of flotation rate constants in a stirred flotation tank and validated against experimental data. The model incorporated local, ...
