A review on opportunities for the development of heat pump drying systems in South Africa
(South African Journal of Science, 2014-05-28)
Recently, it has been discovered that heat pump drying is an efficient method of drying for drying industries. Heat pumps deliver more heat during the drying process than the work input to the compressor. Heat pump drying ...
Demand-SideManagement of Solar Microgrid Operation: Effect of Time-of-Use Pricing and Incentives
(Hindawi, 2020-06-05)
Over 17% of the world’s population lack access to electricity, the majority being in rural areas of sub-Saharan Africa and South
Asia. Microgrid technologies are a promising solution towards rural and remote area ...
Cryptogamic Packed Biofilter as Potential Adsorbent for CO2, NH3, and H2S Impurities from Biogas
(Hindawi, 2020-07-07)
The presence of elevated concentrations of carbon dioxide, hydrogen sulfide, ammonia, and trace impurities in biogas affect its caloric value as well as causes corrosion and is extremely toxic. There are various methods ...
Engine performance, exhaust emissions and combustion characteristics of a CI engine fuelled with croton megalocarpus methyl ester with antioxidant
(Elsevier Ltd., 2011-08)
The use of biodiesel as a substitute for petroleum-based diesel has become of great interest for the reasons of combating the destruction of the environment, the price of petroleum-based diesel and dependency on foreign ...
Impact of antioxidant additives on the oxidation stability of biodiesel produced from Croton Megalocarpus oil
(Elsevier Ltd., 2011-06)
The increase in crude petroleum prices, limited resources of fossil fuels and environmental concerns have led to the search of alternative fuels, which promise a harmonious correlation with sustainable development, energy ...
Experimental Investigations of Oxidation Stability of Biodiesel Produced from Manketti Seeds Oil (Schinziophyton rautanenii)
(ACS Publications, 2011-04-12)
In this study, biodiesel from Manketti seeds oil (Schinziophyton rautanenii) was investigated to determine its suitability for use as a petrodiesel substitute. The fuel-related properties of Manketti oil methyl ester (MOME) ...
Trends towards Effective Analysis of Fluorinated Compounds Using Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
(Hindawi, 2021-02-03)
Increased demand for monitoring and identification of novel and unknown fluorinated compounds (FCs) has demonstrated the need of sensitive fluorine-specific detectors for unknown FCs in both biological and environmental ...
Thermal Performance Analysis of Solar Dryer Integrated with Heat Energy Storage System and a Low-Cost Parabolic Solar Dish Concentrator for Food Preservation
(Hindawi, 2020-07-30)
Solar energy has become a viable alternative energy because it is a clean type of energy that converts solar radiation into heat energy for various applications such as heating water, power generation, cooking, and food ...
Performance analysis of a runner for gravitational water vortex power plant
(Wiley & Sons Ltd, 2022-02-14)
Micro-hydropower can be used to meet the needs of both isolated and rural com munities for electricity. Due to its inexpensive initial investment, simple design,
easy maintenance and low-head utilisation, the gravitational ...
Sub- and Supercritical Water Gasification of Rice Husk: Parametric Optimization Using the I-Optimality Criterion.
(ACS Publications, 2021-05-18)
In this study, rice husk biomass was gasified under sub- and supercritical water conditions in an autoclave reactor. The effect of temperature (350-500 °C), residence time (30-120 min), and feed concentration (3-10 wt %) ...
