(South African Institute of Chemical Engineers, 1995)Please read abstract in the article.
-
(Springer, 2000-04)Intumescent flame retardants form a foamed-char barrier layer when exposed to a flame. Conventional systems are based on the acid catalysed dehydration of carbonifics such as dipentaerythritol. Metal oxides also have utility ...
-
(South African Institution of Civil Engineering, 2002)The aim of this paper is to present laboratory results on the effectiveness of a proprietary urea-formaldehyde (UF) resin as a soil stabiliser. The Indirect Tensile Strength (ITS) was used to characterise the soil ...
-
(South African Institute of Chemical Engineers, 2003)The Indirect Tensile Strength (ITS) was used to characterise the soil stabilising properties of a urea-formaldehyde (UF) resin. The test soil was brown shale gravel. Synergistic strength improvements were obtained when ...
-
(Springer, 2003-03)Calcium gluconate monohydrate is a member of a new class of base-catalysed intumescent compounds. It forms low-density closed-cell carbonaceous foam when exposed to heat. The volume expansion can be as high as two hundred ...
-
(Cambridge University Press, 2003-06)The compound ammonium D-gluconate (C6H11O7−NH4+) has been studied by X-ray powder diffraction. The powder diffraction pattern and data obtained at room temperature are presented (cell data and powder data summary).

(Water Research Council, 2007-04)Please refer to abstract in article
-
(Water Research Council, 2008-04)Please refer to abstract in article
-
(Water Research Council, 2008-04)Communities surrounding an integrated Kraft mill noticed odours from the mill’s effluent treatment plant. A project was therefore commissioned by the mill to proactively manage the odours from both the pulp-processing ...
-
(Water Research Council, 2008-04)Please refer to abstract in article
-
(Elsevier, 2008-05)Batch kinetic experiments at 150 °C, 200 °C and 250 °C showed that the reaction can be modeled with a three step sequential reaction scheme. This involves firstly linear isomerisation of 1-hexene followed by skeletal ...
-
(Water Research Council, 2008-07)Wastewater minimisation in chemical processes has always been the privilege of continuous rather that batch plants. However, this situation is steadily changing, since batch plants have a tendency to generate much more ...
-
(Springer, 2008-08)Anionic surfactant intercalated layered double hydroxides (LDH) of high purity are easily prepared via direct coprecipitation and also by the ion exchange method provided that the precursor contains a monovalent anion, ...
-
(Elsevier, 2008-11)A mixed-culture of bacteria collected from a wastewater treatment plant in Brits, North- West Province (South Africa) biocatalytically reduced Cr(VI) at much higher concentrations than previously observed in cultures ...
-
(Elsevier, 2008-12)Please refer to abstract in article
-
(Elsevier, 2009)The integrated gasification combined cycle (IGCC) is an electrical power generation system which offers efficient generation from coal with lower effect on the environment than conventional coal power plants. However, ...
-
(Elsevier, 2009)Coal extraction experiments were conducted using a coal, containing ca. 10% ash, from the Tshikondeni mine in South Africa. This coal dissolves only to a limited extent in pure polar aprotic solvents such as dimethylformamide ...
-
(Elsevier, 2009)A novel operational policy, the Process Intermediate Storage operational policy, is introduced and used to synthesize, schedule and design multipurpose batch plants. The model is based on the State Sequence Network and ...
-
(Elsevier, 2009)This paper presents a methodology for wastewater minimisation in multipurpose batch plants characterised by multiple contaminant streams. Firstly a situation in which central reusable water storage does not exist is ...
-
(Elsevier, 2009)A mathematical technique for optimization of energy use through the exploitation of heat storage in heat integrated multipurpose batch plants is presented in this document. Storage of heat is effected through the use of a ...
