Process optimization for partial oxidation of bacterial sludge in a sonochemical reactor
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: It was found that bacterial sludge from anaerobic water treatment systems is produced internationally at a rate of 60 grams per person per day and the accumulation of the potentially hazardous by-product ...
Estimating particle size of hydrocyclone underflow discharge using image analysis
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Hydrocyclones are stationary separating machines that separate materials based on centrifugal separation and are widely used in chemical engineering and mineral processing industries. Their design and ...
Process monitoring with restricted Boltzmann machines
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Process monitoring and fault diagnosis are used to detect abnormal events in processes. The early detection of such events or faults is crucial to continuous process improvement. Although principal component ...
On-line monitoring of base metals solutions in flotation using diffuse reflectance spectrophotometry
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: This work evaluates the use of inverse least squares (ILS) and classical least squares (CLS) models for calibration of a diffuse reflectance spectrophotometer for on-line monitoring of the aqueous phase ...
Flow behavior, mixing and mass transfer in a Peirce-Smith converter using physical model and computational fluid dynamics
(Stellenbosch : University of Stellenbosch, 2011-03)

Change-point detection in dynamical systems using auto-associative neural networks
(Stellenbosch : Stellenbosch University, 2012-03)
ENGLISH ABSTRACT: In this research work, auto-associative neural networks have been used for changepoint
detection. This is a nonlinear technique that employs the use of artificial neural
networks as inspired among other ...
Process monitoring and fault diagnosis using random forests
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Fault diagnosis is an important component of process monitoring, relevant in the greater context of developing
safer, cleaner and more cost efficient processes. Data-driven unsupervised (or feature ...
Estimation of concentrate grade in platinum flotation based on froth image analysis
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Flotation is an important processing step in the mineral processing industry wherein valuable minerals
are extracted. Flotation is a difficult process to control due to its complexity, meaning that the ...
On-line monitoring of hydrocyclones by use of image analysis
(Stellenbosch : University of Stellenbosch, 2011-03)
ENGLISH ABSTRACT: Hydrocyclones are separation devices that are widely used throughout the chemical engineering and mineral processing industries. Although simple in design, the intricate flow structure of the device ...
Multiscale process monitoring with singular spectrum analysis
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: Multivariate statistical process control (MSPC) approaches are now widely used for performance monitoring, fault detection and diagnosis in chemical processes. Conventional MSPC approaches are based on ...
