Flue gas desulphurization using natural calcium based sorbents.
(2013)Power generation from coal combustion serves as a major source of energy however this process has detrimental environmental effects. SO₂ is a destructive pollutant and is oxidized with water vapour to form sulphuric acid ... -
Fluidised bed gasification of spent soda and sulphite liquors from the paper industry.
(2004)The pulp and paper industry uses pulping chemicals for the treatment of bagasse, straw and wood chips. Spent liquor or effluent liquor, with high carbon content is produced and sent to chemical recovery to recover pulping ... -
Fluidization and sedimentation behaviors of nanoparticles.
(2020)A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 to 100 nanometers in diameter. Nanoparticles were used by artisans since prehistoric times, albeit without knowledge of their ... -
Formulation and application of a dynamic model for atmospheric point sources.
(1977)No abstract available. -
Forward osmosis of stored urine.
(2016)Source separation of urine from domestic waste water provides a sustainable way of managing nutrient and water recovery from urine. This study was performed in the context of the Bill &Melinda Gates (BMFG) foundation’s ... -
Fractionation and valorisation of bark extractives from Eucalyptus species.
(2018)The notion of zero-waste in industrial production processes of widely used materials has gained momentum, as industries aim to gain revenue from waste materials which were previously considered as waste. Tree bark from ... -
Gas residence time testing and model fitting : a study of gas-solids contacting in fluidised beds.
(1984)This work is concerned with the effect of vessel geometry on the hydrodynamics of fluidisation of a bed of milled iron oxide. The effect of going from a cold model representative of a typical pilot plant reactor to one ... -
Gas-phase epoxidation of hexafluoropropylene.
(2012)A process was developed for the production of hexafluoropropylene oxide via the gas-phase oxidation of hexafluoropropylene with molecular oxygen. The non-catalytic oxidation reaction was investigated in an isothermal, ... -
Gas-phase ethylene polymerization studies using a magnesium chloride-supported Ziegler-Natta catalyst.
(2006)The gas phase polyethylene production process is the most recently developed and boasts many -
A gate-to-gate life cycle assessment of a pulp and paper mill in South Africa.
(2007)Life Cycle Assessment (LCA) is a tool for the evaluation of environmental impacts of a -
High pressure phase equilibrium studies.
(2018-09-17)This project involved the design, construction and commissioning of a new isothermal multipmpose high-pressure vapour-liquid equilibrium (HPVLE) apparatus of the static type. The equilibrium cell was approximately 200 ... -
High pressure vapour-liquid equilibrium data of fluorochemical systems for various temperatures using a new static apparatus.
(2010)The thermodynamic knowledge of accurate phase equilibrium data plays an important role in the design and optimization of separation processes in chemical and engineering industries. Vapour-liquid equilibrium data are ... -
High pressure vapour-liquid equilibrium measurement for perfluorinated chemicals using a static analytical apparatus.
(2016)Abstract available in PDF file. -
High pressure vapour-liquid equilibrium measurements for R116 and ethane with perfluorohexane and perfluorooctane.
(2016)Isothermal binary vapour-liquid equilibrium data are presented for gas –liquid systems for R116 and ethane with perfluorohexane and perfluorooctane. There are no data in the open literature for these systems except for ... -
A high resolution model for multiple source dispersion of air pollutants under complex atmospheric structure.
(1986)No abstract available. -
High temperature flue gas desulfurization: experiments and modelling.
(2018)As stringent environmental regulations regarding SO2 emissions have been enacted in many countries, the removal of SO2 from flue gas has become a necessity. Conventional methods for flue gas desulfurization (SO2 removal) ... -
Highly dispersed zinc-based sorbents for desulphurisation : synthesis and application.
(2016)Abstract available in PDF file. -
Hydrate phase equilibrium data of CO2+H2O+Tetrabutyl ammonium salts (chloride and fluoride).
(2014)The UNFCC’s (United Nations Framework Convention on Climate Change) goal, to stabilize greenhouse gas concentrations through energy technology and prevent anthropogenic interference with the climate system, has led to ... -
Hydrate phase equilibrium studies for Xe, Ar, Kr, and CF4 in the presence of TBAB aqueous solutions.
(2015)Abstract available in PDF file. -
Hydrate technology for the concentration of aqueous salt solutions using fluorinated refrigerants.
(2019)The world is facing a challenge with the scarcity of fresh water, due to an increase in the world population and the large expansion of industrial projects. This results in greater demand for fresh water. In such a scenario, ...
