Optimization and Cost-Oriented Comparison of Ammonia- and Propane-Compression Refrigeration for the Recovery of Natural Gas Liquids
(2013-09)
Optimization and a cost-oriented analysis, including the capital and energy-of-compression costs, were performed to compare propane- and ammonia-refrigeration economizer cycles with and without presaturators. The simulation ...
Fuel recovery from waste oily sludge using solvent extraction
(2010-09)
Solvent extraction was used to recover oil from waste sludge generated from the storage of crude petroleum. Different solvent-to-sludge mass ratios were used for two solvents, methyl ethyl ketone (MEK) and LPG condensate ...
Analysis of a Recent Biofilter Model for Toluene Biodegradation
(2013-01)
This paper investigates and provides a critical analysis of the toluene biofilter model developed by Li and De Visscher. The model simulation results have been reproduced and compared with several sets of experimental data ...
A Measure of Capacity Contribution of Static Mono-Si Photovoltaic Systems
(2013-05)
Photovoltaic (PV) systems generate electricity in the daytime when system demand is generally moderate to high. For Mediterranean countries, there is also seasonal coincidence of high system demand and high PV load factors. ...
Effective Approach for Increasing the Heteroatom Doping Levels of Porous Carbons for Superior CO2 Capture and Separation Performance
(ACS Publications, 2017-09-28)
Development of efficient sorbents for carbon dioxide (CO2) capture from flue gas or its removal from natural gas and landfill gas is very important for environmental protection. A new series of heteroatom-doped porous ...
Novel method for water purification using activated adsorbents developed from sewage sludge
(Taylor & Francis, 2016)
Sewage sludge from Dubai was characterized using inductively coupled plasma and CHN elemental analysis. Selected sludge samples were washed with deionized water until constant conductivity was achieved. The sludge samples ...
Produced Water Treatment Using Naturally Abundant Pomegranate Peel
(Taylor & Francis, 2016)
Pomegranate peel powder (PPP) was employed as a low cost adsorbent for the removal of crude oil from simulated produced water (SPW). The effect of contact time, adsorbent dosage, pH, as well as temperature on the efficiency ...
One-Hour-Ahead Wind Power Forecast Using Hybrid Grey Models
(Inderscience, 2016)
This paper proposes two hybrid grey-based short-term wind power prediction techniques: GM(1,1)-ARMA and GM(1,1)-NARnet. These techniques are combined with ARMA models and nonlinear autoregressive neural network (NARnet) ...
A Mobile GPRS-Sensors Array for Air Pollution Monitoring
(2010-10)
An online GPRS-Sensors Array for air pollution monitoring has been designed, implemented, and tested. The proposed system consists of a Mobile Data-Acquisition Unit (Mobile-DAQ) and a fixed Internet-Enabled Pollution ...
Palm tree leaves usage for biosorption and recovery of heavy metals from wastewater
(Desalination Publications, 2017-06)
Biosorption can be a sustainable water treatment option. However, selection of biosorbent can be challenging and local availability plays an important role. This research investigates the effectiveness of palm tree leaves ...
