In the last years, natural fibers are increasingly investigated as an oil recovery system in order to overcome the oil spillage phenomena, thus preserving environment and aquatic life. In particular, lignocellulose-based fibers have recently been employed with promising results. In such a context, the aim of this paper is to assess the oil sorption capability of natural fibers extracted from the stem of the giant reed Arundo donax L., a perennial rhizomatous grass belonging to the Poaceae family that grows naturally all around the world thanks to its ability to tolerate different climatic conditions. Sorption tests in several pollutants and water as a reference were carried out. The fibers have absorption capacities that are about five to six times their weight. Depending on the high absorption kinetics, possible applicative interests can be identified. Eventually, depending on the fiber size, adsorption properties were related to the microstructure and morphology of Arundo donax fibers.

ABSTRACT The U.S. Coast Guard's success with the high seas skimming barrier prompted the development of a smaller, half-scale version for use in protected bays and harbors. The smaller version (SCOOP) enables more rapid deployment with significantly fewer people. Individual components of the system include a 65-foot section of skimming barrier with redesigned skimming struts, 200 feet of containment boom, two 30-foot work boats for storage, transport, and operation of the system, trailers to carry the boats to the scene, and an oil recovery system including double-acting diaphragm pump, gravity-type oil-water separator, and 750-gallon collapsible storage bags. In tests at the Environmental Protection Agency's Oil and Hazardous Materials Simulated Environmental Test Tank (OHMSETT) facility, the SCOOP exhibited recovery efficiencies between 30 percent and 60 percent over a speed range of 0.5 to 1.75 knots. The oil recovery rate was between 30 and 70 gallons per minute over the same speed range. At speeds below 0.9 knots there were no losses of oil from the boom. The system has been delivered to the Coast Guard Gulf Strike Team in Bay St. Louis, Mississippi, where it is being evaluated through use in routine spill response operations and exercises.

ABSTRACT Although opportunities exist to use shoreline surface washing agents for oil spill removal in freshwater environments, this response technique is seldom tried because little is known about its insitu effectiveness and toxicity. In January 2000, the Federal Region V Regional Response Team chartered a Subcommittee of international, federal, state and industry representatives to develop a protocol for evaluating the test use of shoreline surface washing agents in freshwater environments on oil spills of opportunity in the Great Lakes Region. Currently, mechanical and manual recovery are the primary means of oil spill cleanup in freshwater environments which can be costly, labor intensive, and often results in limited oil recovery. Oil recovery inefficiency is related to shoreline composition and complexity that allow oil to cover, fill, and penetrate the substrate. Responders, with limited options, may compromise their efforts by leaving residual oil in the environment or expend a substantial effort sanitizing the shoreline, which can be more detrimental to the environment. The application of shoreline surface washing agents may improve recovery efficiency and ameliorate long term harm to freshwater shorelines if properly applied. Surface washing agents may also reduce labor requirements typically associated with diminishing returns from continued mechanical or manual cleanups required to achieve similar oil removal results. The RRT V Subcommittee developed a protocol for conducting small-scale insitu tests on the effectiveness and toxicity of surface washing agents to gain experience and confidence in its utility as a response tool in freshwater environments. The resulting protocol guides the user in assessing physical criteria, constraints and special considerations needed to determine if the use of two surface washing agents is appropriate. The protocol also includes procedures for test preparation and application and provides effectiveness, water quality and toxicity monitoring guidelines, data collection, booming, and oil recovery procedures.

The single model of oil shale development, which is, burning in boiler for power generation and distillation for shale oil, may cause enormous waste of oil-gas resources and semi-coke. For energy conservation and efficiency improvement, it is necessary to realize the comprehensive utilization of oil shale. The development of experimental system is foundation of further studying. In the paper, an experimental system for comprehensive utilization of oil shale is designed and realized. These includes: spouted bed combustor and shale ash collection system, oil shale retort with solid heat carrier and shale oil recovery system. With the system, the realistic simulation under different condition such as different kinds of oil shale, operation condition can be studied. This work lays an experimental foundation for the further study of comprehensive utilization of oil shale.
