3-way PLS regression and dual energy gamma densitometry for prediction of total volume fractions and enhanced flow regime identification in multiphase flow
(Journal article; Peer reviewed, 2014-12)Dual energy gamma densitometry and 3-way partial least squares regression were applied to quantify the total volume fractions and improve flow regime identification in multiphase flow. Multiphase flow experiments were ... -
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 ... -
Estimation of gas/liquid and oil/water interface levels in an oil/water/gas separator based on pressure measurements and regression modelling
(Journal article; Peer reviewed, 2013-02-08)Gravity separators are widely used for separation of gas/oil/water/sand from both offshore and onshore oil production facilities. Estimation of the gas/liquid and oil/water interface levels in gravity separators have been ... -
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 ... -
Online acoustic chemometric monitoring of fish feed pellet velocity in a pneumatic conveying system
(Journal article; Peer reviewed, 2014-03-14)Fish farmers consider the cost of fish feed pellets as one of the most expensive factors in fish cultivation. Proper control of the handling and conveying systems is necessary to avoid damage and disintegration of the ... -
Online estimation of wax deposition thickness in single-phase sub-sea pipelines based on acoustic chemometrics: A feasibility study
(Journal article; Peer reviewed, 2012-10-25)Wax deposition in sub-sea oil producing pipelines is a concern to the oil producing companies. The deposition of wax in pipelines can cause serious economic implications if not monitored and controlled. Several researchers ... -
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 ...
