Application of 15N-NMR spectroscopy to analysis of amine based CO2 capture solvents
(Journal article; Peer reviewed, 2014)15N NMR spectroscopy is a useful tool for amine reactivity characterization since it can provide information about the availability of the lone pair of electrons on nitrogen through the measured chemical shift values, which ... -
Composite Distribution Solution for Minimizing Heat Loss in a Pyrolysis Reactor
(Journal article; Peer reviewed, 2011)The article presents a novel design for a distribution plate. The solution is suitable for a reactor vessel where a reactant gas needs to be maintained at a different temperature from the reaction chamber in order to avoid ... -
Equilibria of MEA, DEA and AMP with Bicarbonate and Carbamate: a Raman Study.
(Journal article; Peer reviewed, 2013-08-05)Species distribution analysis in carbonated alkanolamine solution is import in order to estimate accurate thermodynamic properties. The applicability of Raman spectroscopy as an analytical tool for speciation of carbonated ... -
Increased Coal Replacement in a Cement Kiln Burner by Feeding a Mixture of Solid Hazardous Waste and Shredded Plastic Waste
(Journal article; Peer reviewed, 2013-07)The present study aims to find the maximum possible replacement of coal by combined feeding of plastic waste and solid hazardous waste mixed with wood chips (SHW) in rotary kiln burners used in cement kiln systems. The ... -
Investigation into optimal CO2 concentration for CO2 capture from aluminium production
(Journal article; Peer reviewed, 2013-08-05)Capture of CO2 from aluminum production has been simulated using Aspen Plus and Aspen Hysys. The technology used for aluminum production is the Hall-Héroult and the current cell design necessitates that large amounts of ... -
Kiln process impact of alternative solid fuel combustion in the cement kiln main burner - Mathematical modelling and full-scale experiment
(Journal article; Peer reviewed, 2014-02)Increased use of alternative fuels in cement kilns is a trend in the world. However, replacing fossil fuels like coal with different alternative fuels will give various impacts on the overall kiln process due to the fuel ... -
Optimum feeding rate of solid hazardous waste in a cement kiln burner
(Journal article; Peer reviewed, 2013)Solid hazardous waste mixed with wood chips (SHW) is a partly CO2 neutral fuel, and hence is a good candidate for substituting fossil fuels like pulverized coal in rotary kiln burners used in cement kiln systems. SHW is ... -
Process Simulation of Calcium Looping With Indirect Calciner Heat Transfer
(Conference object; Peer reviewed, 2015-11-25)In calcium looping (CL), calcium oxide (CaO) is used as a sorbent for carbon dioxide (CO2). The CO2 reacts with CaO to produce calcium carbonate (CaCO3) in a carbonator operating at about 650 °C. The CaCO3 is then sent to ... -
The effect of alternative fuel combustion in the cement kiln main burner on production capacity and improvement with oxygen enrichment.
(Journal article; Peer reviewed, 2013)A mathematical model based on a mass and energy balance for the combustion in a cement rotary kiln was developed. The model was used to investigate the impact of replacing about 45 % of the primary coal energy by different ...
