FEASIBILITY STUDY ON MICROALGAL BIOFUEL PRODUCTION Joash Savaris Castro Abstract Oil price is a major issue globally as oil is a major requirement in almost all industries to operate. Another arising issue is the diminishing supply of fossil fuel or crude oil from major suppliers. With these in mind‚ researches for a potential alternative source of fuel are conducted all over the world. Microalgae is found to be a potential feedstock for the production of biofuel. Production of biofuel from

is moving through the stationary phase‚ it picks up compounds that need to be tested‚ taking those compounds with it. Through adsorption‚ the mobile phase separates into different components (soinc). The mobile phase can be liquid‚ gas‚ or supercritical fluid. How Does Chromatography Work? Chromatography is a surface effect. It works by first starting off with an unidentified liquid being injected into a column. As the chemicals in the liquid move down the column‚ they separate depending on their

produced from water by combustion of fuel. According to ASME a steam generating unit is defined as: “ A combination of apparatus for producing‚ furnishing or recovering heat together with the apparatus for transferring the heat so made available to the fluid being heated and vapourised ”. Boilers Steam generated is employed for: (i.) Generating power in steam engines or steam turbines. (ii.) Heating the buildings in cold weather and for providing hot water supply. (iii.) In textile and chemical industries

simple‚ precise and accurate solvent extraction method is described for the separation and estimation of Indium in geological materials. Solvent extraction of Indium from 6 M HCl medium using tri-n-butyl phosphate‚ selectively separates Indium from accompanying elements in different type of geological samples. Acid hydrolysis of Nb/Ta samples separates Indium from major matrix elements like Nb and Ta and the remaining elements do not influence the selective extraction and preconcentration of In and its

induced earthquakes. Wastewater disposal is the primary cause of the recent increase in earthquakes in the central United States. Wastewater disposal wells operate for durations and inject much more fluid than hydraulic fracturing‚ making them more likely to induce earthquakes. Enhance oil recovery injects fluid into rock layers where oil and gas have already been extracted‚ while wastewater injection often occurs in never-before-touched rocks. Therefore‚ wastewater injection can raise pressure levels

In Oklahoma‚ less than 10% of the water injected into wastewater disposal wells is used hydraulic fracturing fluid. Most of the wastewater in Oklahoma is saltwater that comes up along with oil during the extraction process. In contrast‚ the fluid disposed of near earthquake sequences that occurred in Youngstown‚ Ohio‚ and Guy‚ Arkansas‚ consisted largely of spent hydraulic fracturing fluid. Induced seismicity can occur at significant distances from injection wells and at different depths. Seismicity
