Studies on Waste Water Treatment in Three Phase Semifluidized Bed Bioreactors: Computer Aided Analysis and Software Development
Abstract: Design and performance analysis of three phase semifluidized biofilm reactors for aerobic treatment of industrial effluents have been attempted. Bioconversion processes that follow Monod-type kinetics and those following Haldane-Andrews kinetics (involving substrate inhibition to microbial growth) have been considered as typical cases. The bioreactor has been modelled mathematically by solving performance equations separately for the packed section and for the fluidized section, considering dispersed flow in both of these sections, …

Development of Nanoparticles as Additive to Drilling Mud to be Used as Viscosity and Filtrate Loss Modifier
Abstract: Conventional drilling fluids are often unable to fulfill certain functional tasks that are very important in challenging environment. This inefficiency of drilling fluid in performing certain task is mainly because of lack in particular rheological or filtrate loss properties. Hence, the industry is looking for a new kind of additives which can be helpful in maintaining these properties in desired range even under extreme conditions. Rice husk is an abundantly …

Removal of Thiophene from Model Fuel Using Titanium Catalyst
Abstract: Organosulfur compounds like thiophene (Th) and its alkyl derivatives are the major unwanted species present in crude oil fractions as they lead to the formation of sulfur oxides after combustion of the fuel and these oxides of sulfur cause severe environmental damage. Oxidative desulfurization (ODS) process is considered as one of the best alternative deep desulfurization technologies compared to hydrodesulfurization. In the ODS process, the sulfur compounds are oxidized to …

Studies on Biological Degradation of 4-Bromophenol Using Anaerobic, Anoxic and Aerobic Bioreactors
Abstract: The present study investigates biodegradation of 4-Bromophenol (4-BP) and simultaneous removal of COD in anaerobic, anoxic and aerobic moving bed bioreactors. Cow dung slurry was used as a source of microbial consortium for acclimatization in moving bed reactors in batch mode. The acclimated microbial consortium was able to degrade various concentrations such as 5, 10 and 15 mg/l of 4-BP within specific time period. Biodegradation was evaluated by determining total …

Studies on Naturally Extracted Surfactant to Enhance Flow Properties of Crude Oil
Abstract: Indian heavy crude oil sample from Gujarat was studied for improvement of properties such as pour point, wax crystal structure, particle size analysis and viscosity by addition of a novel surfactant extracted from a tropical Indian plant Sapindus mukorossi. Characterization was done to find the effect of surfactant addition on individual components of the crude oil such as saturates, asphaltenes, resins and aromatics. The objective was to increase the flowability …

Selection and Preparation of Solvent for Wax Dissolution in Heavy Crude Oil Wells
Abstract: Remedial measures for wax deposition problems in production wells are very hectic due to production down time and expenditure required for removal of heavy and waxy crude oil. Chemical treatment techniques with solvent formulation derived from many laboratory experiments were carried out with the waxy crude oil sample to recover the solidified wax inside the pipelines and wellbores. A list of chemical solvents including three dispersants was mixed in different …

Electrooxidation Study of Acetic Acid at Low Temperature in Membrane Less Microfluidic Fuel Cell for Portable Power Application
Abstract: The global energy crisis due to dependence on fossil fuel and its limited reserves followed by environmental pollution are the key concerns to the research communities. However, recently developed micro-fluidic fuel cells using hydrogen-rich fuels are most likely to replace the batteries, due to their compactness, high efficiency and simplicity in operation. In this context, the PtxSn/C (where, x=1, 3, 5) electrode-catalysts were prepared and the electro-oxidation of acetic acid …

Reduction of Chemical Oxygen Demand of Industrial Reverse Osmosis (RO) Reject Water by Hydrogen Peroxide Treatment
Abstract: Reverse osmosis (RO) technology is now applied in many industrial water treatment processes for producing low saline water which are required for demineralized water production for boiler operation of thermal power generation plant, metallurgy and many others. The RO reject water having high salinity are mostly rich in sodium, potassium, calcium, magnesium, and other metal salts of chloride, sulphate, sulphite, nitrate, nitrite, silica (SiO2), carbonate, bicarbonate, hydroxide and many other …

Studies on Production of Biogas by Co-digestion of Sewage Sludge, Wastepaper and Waste Grown Algae
Abstract: Abundantly produced sewage sludge in wastewater treatment plants and algae grown in wastewater are the potentially important biomass for the production of biogas. Experimental investigations have been conducted to study the feasibility of co-digestion of the organic fraction of municipal sludge, waste paper, and waste grown algae under anaerobic mesophilic (37oC) conditions in lab-scale bioreactors. Quantity and quality of the biogas, volatile solid reduction and start-up period for the reactions …

Studies on Flow of Emulsified Crude Oil through Horizontal Pipelines
Abstract: The experiments were carried out in a 1 in horizontal pipe to study the effect of water content on pressure drop during the flow of crude oil at different flow rates and temperature conditions. Crude oil collected from the North Santhal city (Mehsana) was used as test fluid. The experiments were conducted to understand the influence of the water content and temperature at different flow rates. Triton X-100 (TX-100) was …

Surface Chemistry of Flotation
Abstract: Flotation technology is widely used to recover and concentrate minerals from the ores. The technique involves, inducing surface hydrophobicity to a mineral selectively and collect the same through air bubbles from aqueous phase. For the efficient design of flotation processes and equipment, an in-depth understanding of hydrophobic hydration of floatable mineral particles is essential. The different theories associated with and the underlying mechanisms are surveyed in this paper.Cite this Article …

Short Communication Defluidization Using High-Alkali Content Fuels in Fluidized Bed Biomass Gasifiers
Abstract: A major problem however often encountered in fluidized beds is bed agglomeration, which may result in total defluidization, leading to unscheduled downtime and additional costs. This problem is found to be critical in fluidized bed combustion and gasification of biomass fuels which have high ash and alkali contents [1]. Biomass fuels, especially herbaceous plants, often contain significant amounts of silicon, potassium and calcium, together with chlorine and sulphur. These elements …

How to be A Successful Entrepreneur?
Abstract: The term entrepreneur appears to have been introduced by Richard Cantillon, an Irish economist of French descent, in early 1700. According to Cantillon's original formulation, the entrepreneur is a specialist in taking on risk. He insures workers by buying their products (or their labor services) for resale before consumers have indicated how much they are willing to pay for them. Entrepreneurship thus calls for a gut feel for things, a …
