Ultrafiltration of Lignin rock from black liquor obtained from a South African kraft mill.
(2015)This study focused on investigating the possibility of extracting lignin from black liquor generated from South African Kraft mill black liquors. Although ultrafiltration has been applied successfully and widely to extract ... -
The use of n-dodecane as a solvent in the extraction of light alcohols from water.
(2008)Phase equilibrium data is essential in the operation, design and development of industrial -
The use of water pinch analysis to determine optimum effluent treatment conditions for an integrated pulp and paper mill.
(2005)Pulp and paper mills are facing the possibility of stricter effluent discharge limits. End-of-pipe treatment for discharge no longer guarantees compliance, nor is it the most cost-effective way of solving mills' effluent ... -
Utilisation of bagasse for the production of C5- and C6- sugars.
(1982)Surplus sugarcane bagasse, estimated at a maximum of 0,9x106 tons/year, represents an annual renewable resource which is readily available at the mill site and is a suitable potential source of alternative fuels and ... -
Vapour-liquid equilibria and infinite dilution activity coefficient measurements of systems involving diketones.
(2003)Acetylpropionyl (2,3-pentanedione) and diacetyl (2,3-butanedione) are by-products of sugar manufacture. Both diketones have many uses, mainly food related. Vapour-liquid equilibrium data and infinite dilution activity ... -
Vapour-liquid equilibria studies for binary systems containing 1-hexene and n-hexane
(2009)Experimental vapour-liquid equilibria (VLE) data is required for the design of separation -
Vapour-liquid equilibrium measurements at moderate pressures using a semi-automatic glass recirculating still.
(2014)Vapour-liquid equilibrium (VLE) data of high accuracy and reliability is essential in the development and optimization of separation and chemical processes. This study focuses on satisfying the growing demand for precise ... -
Vapour-liquid equilibrium measurements using a static total pressure apparatus.
(2006)A novel static total pressure apparatus was designed, built and commissioned for the measurement of VLE data at low to moderate pressures and temperatures. The apparatus of Fischer and Gmehling [1994] was used as a basis ... -
Vapour-liquid equilibrium of carboxylic acids.
(2005)VLE data is essential for the design and optimisation of industrial separation processes. Carboxylic acids are of significant interest because of their importance in both industrial and biological processes. Carboxylic ... -
Vapour-liquid equilibrium studies at low pressure using a static-cell cluster.
(2006)Phase equilibrium data are vital in process design for chemical industries. Development of -
A vapour-liquid equilibrium study on sub-critical systems using a static apparatus.
(2009)High pressure vapour-liquid equilibrium experiments were undertaken with a static high-pressure apparatus designed by Prof. J. D. Raal and commissioned by Prof. D. Ramjugernath. Isothermal VLE binary data data was measured ... -
Waste water treatment of effluents from corn processing plant.
(2013)South Africa is facing numerous challenges that pertain to increasing water deficit and pollution of water resources. Only 40 out of 821 wastewater treatment works in South Africa achieved Green Drop certifications in the ... -
Water usage in the South African pulp and paper industry.
(2004)The pulp and paper industry holds a reputation in the public eye for being a large consumer of water. This dissertation analyses water usage within the industry with a particular application to the South African pulp and ... -
Wet and dry desulphurization technologies: modelling and simulation.
(2019)Energy demand continues to increase with population growth and economic development therefore numerous technologies have been proposed over the years to convert coal to electricity. Turbine cycles have received a great ... -
Wetting and separation efficiency of polypropylene packing modified by nanoparticles.
(2018)Packed columns are one of the main unit operations used in distillation, extraction, absorption and hydrotreating due to their ease of operation, versatility and adaptability to different chemical systems. The distribution ...
