Trace element behaviour in the Sasol-Lurgi fixed-bed dry-bottom gasifier. Part 3. The non-volatile elements: Ba, Co, Cr, Mn, and V
(Elsevier, 2009)
Coal contains most of the naturally occurring chemical elements in (at least) trace amounts, with specific elements and their concentrations dependent on the rank of the coal and its geological origins. The focus of this ...
The adsorption of copper in a packed-bed of chitosan beads: Modeling, multiple adsorption and regeneration
(Elsevier, 2009)
In this study, exoskeletons of Cape rock lobsters were used as raw material in the preparation of chitin that was successively deacetylated to chitosan flakes. The chitosan flakes were modified into chitosan beads and the ...
A study of the effect of MPLS on Quality of Service in Wireless LANS
(OPNET Technologies, 2008)
The development process of an axial active magnetic bearing
(2005)
The purpose of this paper is to motivate and inspire students to investigate and understand fundamental
principles of electrical engineering such as magnetic levitation, control theory and sensor design. This paper describes ...
A current analysis and correction system for vibration forces on the rotor of a rotating active magnetic bearing system
(SAIEE, 2007)
In this paper, an on-line detection, correction and identification system for vibration forces on the rotor of a rotating active magnetic bearing is proposed. The on-line detection system performs current analysis by ...
Trace element behaviour in the Sasol-Lurgi MK IV FBDB gasifier. Part 2. The semi-volatile elements: Cu, Mo, Ni and Zn
(Elsevier, 2009)
Gasification is a coal conversion process that could be considered to be more amenable with regards to environmental impact factors when compared to combustion, as it provides minimum direct emission to the atmosphere due ...
Coal char temperature profile estimation using optical reflectance for a commercial-scale Sasol-Lurgi FBDB gasifier
(Elsevier, 2008)
In the Sasol-Lurgi fixed-bed dry-bottom (FBDB) gasifier the temperature in the combustion zone should not exceed the melting point of the ash-forming minerals, causing them to melt/flow and agglomerate. Sintering of ash ...
Sulfur behavior in the Sasol-Lurgi fixed-bed dry-bottom gasification process
(ACS, 2009)
This article reports on the findings of a study regarding the sulfur behavior across a Sasol−Lurgi gasifier. This was undertaken to understand the behavior of the various sulfur-bearing components in the coal, as they are ...
Electron beam and Mössbauer techniques combined to optimise base metal partitioning in the furnace
(Springer, 2008)
Furnace slag and matte samples from Anglo Platinum smelters were analysed using a combination of electron microbeam and Mössbauer techniques. The object of the investigation was to establish the distribution of the base ...
Analysis of the porous structure of an annular pebble bed reactor
(Atomic Energy Society of Japan, 2009)
This paper discusses the numerical analysis of the porous structure of an annular packed bed. Numerical procedures are described to determine the variation in the porosity, the variation in the coordination number (measure ...
