Use of bamboo fiber in oil water separation

One of the environmental issues facing the society is the separation of oil from water in emulsions. Oily wastewater enters into the environment through many ways such as oil spill as well as from the industry. Natural fibers are a viable alternative to synthetic fibers in separating oil from the water. The oil physical characteristics and sorbents made from the fiber influences the sorption of oil onto the fiber. This work uses the naturally available bamboo fibers for separation of oil from water. Very high adsorption capacities were obtained for vegetable oil. Furthermore, recovery of oil was also tested and 90% recovery was obtained. Bamboo fiber has thus great advantage in treating oil-water mixture

Fossil Fuels: Oil

This lesson provides an introduction to the world oil market and the United States' dependence on it. Topics include our current usage, sources, and the political implications of acquiring oil from an international market. There is also discussion of how petroleum is created and trapped in reservoirs, and how oil companies find it. The lesson includes an activity in which students use an online game that simulates the exploration and production of petroleum. To win, they must actually 'produce' commercial quantities of oil or gas by drilling in the ground in a 8-by-8 mile plot of land with a budget of $2 million dollars.

Electrobioremediation of oil spills

Annually, thousands of oil spills occur across the globe. As a result, petroleum substances and petrochemical compounds are widespread contaminants causing concern due to their toxicity and recalcitrance. Many remediation strategies have been developed using both physicochemical and biological approaches. Biological strategies are most benign, aiming to enhance microbial metabolic activities by supplying limiting inorganic nutrients, electron acceptors or donors, thus stimulating oxidation or reduction of contaminants. A key issue is controlling the supply of electron donors/acceptors. Bioelectrochemical systems (BES) have emerged, in which an electrical current serves as either electron donor or acceptor for oil spill bioremediation. BES are highly controllable and can possibly also serve as biosensors for real time monitoring of the degradation process. Despite being promising, multiple aspects need to be considered to make BES suitable for field applications including system design, electrode materials, operational parameters, mode of action and radius of influence. The microbiological processes, involved in bioelectrochemical contaminant degradation, are currently not fully understood, particularly in relation to electron transfer mechanisms. Especially in sulfate rich environments, the sulfur cycle appears pivotal during hydrocarbon oxidation. This review provides a comprehensive analysis of the research on bioelectrochemical remediation of oil spills and of the key parameters involved in the process

How Best to Auction Oil Rights

I study the design of oil rights auctions. A good auction design promotes both an efficient assignment of rights and competitive revenues for the seller. The structure of bidder preferences and the degree of competition are key factors in determining the best design. With weak competition and additive values, a simultaneous first-price sealed-bid auction may suffice. With more complex value structures, a dynamic auction with package bids, such as the clock-proxy auction, likely is needed to promote the efficiency and revenue objectives. Bidding on production shares, rather than bonuses, typically increases government take by reducing oil company risk.Auctions, Oil Auctions, Market Design, Clock Auctions

The impact of oil price fluctuations on stock markets in developed and emerging economies

This study examines the response of stock markets to oil price volatilities in Japan, Singapore, Korea and Malaysia by applying the generalized impulse response and variance decomposition analyses to the monthly data spanning 1986:01 – 2011:02. The results suggest that the reaction of stock markets to oil price shocks varies significantly across markets. Specifically, the stock market responds positively in Japan while negatively in Malaysia; the signal in Singapore and South Korea is unclear. We find that the stock market inefficiency, among others, appeared to have slowed the responses of the stock market to aggregate shocks such as oil price surges.oil price fluctuation, stock return, exchange rate, emerging market, VAR model.
