Studies on Microwave-Assisted Extraction of Drumstick Tree (Moringa oleifera) Seed Oil

ABSTRACT The need for effective and efficient means of oil extraction has been a concern in recent time. Hence, this study aimed at the oil extraction from Moringa oleifera seeds using the Microwave-Assisted extraction method. The extraction process was modeled using Response Surface Methodology (RSM). Also, the evaluation of Moringa oleifera oil as a good feedstock for biodiesel production was carried out. Oil was extracted from the M. oleifera seed kernel using Microwave-Ass...

Natural Gas Flaring—Alternative Solutions

Gas flaring is one of the major problems in the world. It consumes useful natural resources and produces harmful wastes, which have negative impacts on society. It is one of the most tedious energy and environmental problems facing the world today. It is a multi-billion dollar waste, a local environmentalcatastrophe and environmental problem which has persisted for decades. From the year 1996-2010, in Nigeria, 12,602,480.25 million ft 3 of natural gas was flared (NNPC). This is equivalent to ...

Gas Hydrate—Properties, Formation and Benefits

There are numerous gas hydrate reserves all over the world, especially in permafrost regions and ocean environments. The abundance of gas hydrate reserves is estimated to be more than twice of the combined carbon of coal, conventional gas, and petroleum reserves. These hydrate deposits hold a significant amount of energy which can make hydrate a sustainable energy resource. The comprehensive research on the properties and formation of methane hydrates is paramount to ensure efficient and effe...

A Generalized Correlation for Predicting Ethane, Propane, and Isobutane Hydrates Equilibrium Data in Pure Water and Aqueous Salt Solutions

Hydrate formation can cause serious problems in hydrocarbon exploration, production, and transportation, especially in deepwater environments. Hydrate-related problems affect the integrity of the deepwater platforms, leads to equipment blockages, and also increases operational costs. In order to solve these problems, salts are used as thermodynamic inhibitors and also mixed with the drilling fluids in most drilling processes. A comprehensive understanding of hydrate formation in aqueous salt ...

Methane Hydrate Dissociation Conditions in High-Concentration NaCl/KCl/CaCl 2 Aqueous Solution: Experiment and Correlation

The dissociation conditions of methane hydrate in high concentration aqueous solutions of NaCl, KCl, and CaCl2 are reported in this work. A total of 80 sets of H−L−V equilibrium data of methane hydrate in aqueous solutions of NaCl (9.45−23.71 wt %), KCl (13.93−21.88 wt %), and CaCl2 (13.78−35.50 wt %) were measured at the temperature range of (273.65−291.85) K and the pressure range of (5.43−65.12) MPa. A modified step-heating method with high efficiency was employed in the meas...

One of the key factors that influence this is increased availability of feed for animals. The use of mixing machines ...

Domestic water treatment using moringa oleifera seed powder

ABSTRACTMost people living in rural communities, have no access to good domestic water for consumption. The inhabitants depends on rain water, well water and sometimes surface water for consumption. Improper treatment of water gotten from these sources, can lead to the spread of water borne diseases, because, sometimes the water gotten from these sources are turbid. Although, some inhabitants use alum to treat the water so as to make the water clear. But excessive usa...

DESIGN OF SIX-STROKE INTERNAL COMBUSTION SPARK IGNITION ENGINE

ABSTRACTThe rate at which energy is lost by human activities is enormous. There is need to work on how to generate more energy and minimize the usage of the generated energy. In an internal combustion engine, there is need to focus on gaining energy usage by using generated heat during combustion process. To reduce the energy usage, emission rate and improve the efficiency of four-stroke internal combustion spark ignition engine, the four-stroke internal combustion spark ignition engine is mo...

Construction of a DIGITAL AC VOLTMETER

This project- construction of a digital voltmeter seeks to utilize the microcontroller to build a digital voltmeter having better accuracy by utilizing a successive approximation analogue to digital converter ADC to measure the voltage (0 – 250V). Here, the working principal and components of this device are extensively explained. This Digital voltmeters (DVM) display the measured voltage using LCDs (Liquid Crystal Display) to display the result in a floating point format.
