Oil spills impose serious damage to the environment. A spilled crude oil or its products affect aquatic flora and fauna and influence the atmosphere as well. Such pollutants are especially dangerous for the water ecosystems, where biological self-purification processes are slower (for example the Baltic Sea), than in warmer regions. In this paper, we evaluate a Cited by: Sorbents. Sorbents are materials used to absorb oil, and include peat moss, vermiculate, and clay. Synthetic varieties – usually plastic foams or fibers – come in sheets, rolls, or booms. Because oil-filled sorbents must be collected and treated, they are most often used on small spills or as "polishers" after other response options have.
Some of the properties evaluated were oil and water sorption capacity, oil retention, buoyancy retention with and without absorbed oil, effect of petroleum product variation, sorbent/oil . Sorbent booms are considered a ‘first line of defence’ technology used for containing and minimizing the impacts of crude oil spills. Booms containing human hair waste as sorbent were compared to other natural sorbents, including cotton by-product, recycled cellulose, as well as booms containing synthetic polypropylene, in order to evaluate their effectiveness in adsorbing Cited by: 8.
To selectively absorb oil from oil spills in the ocean a sorbent would need a relatively high ratio. Cleanup If you made any oily messes, . There is an increasing awareness of the impact of spilled crude oil and its refined products on human health and environment. The potential of using groundnut husk, agro-based waste, which is .

Publication entitled "Selection Criteria and Laboratory Evaluation of Oil Spill Sorbents". Updates to this publication were release every four or five years.
The time lag between publications and the limited number of sorbents tested were acceptable limitations to this program as interest in sorbents was relatively limited. Since that time; however, interest in sorbent performance evaluation. A four part standard sorbent laboratory test procedure was developed to evaluate a number of sorbents.
The sorbents were tested using three different petroleum products, which were aged for periods of one and seven days. Additional Physical Format: Online version: Selection criteria and laboratory evaluation of oilspill sorbents. Ottawa, Ont., Canada: Environment Canada, . The main categories are oil spills on water, oil spills on land, and industrial use.
The characteristics we will be evaluating with the new test protocols include initial and maximum sorption capacities, water pickup, buoyancy, reuse potential, retention profile, disintegration (material integrity), and ease of application and by: A new absorbent has been developed for oil spills.
It attracts oil and chemicals and floats on water indefinitely. It can then be disposed of in an environmentally acceptable manner or recycled.
The new absorbent is called “Sea Sweep” and extensive research has been done on it under an EPA Small Business Innovation Research : Thomas B. Reed, William L.
Mobeck, Siddhartha Gaur. Mechanical recovery of oil by oil sorbents is one of the most important countermeasures in marine oil-spill response. Polypropylene is the ideal material for marine oil-spill recovery due to its low density, low water uptake and excellent physical and chemical resistance.

Selection Guide for Oil Spill Response Countermeasures. Workers on the South Korean shoreline clean up oil spilled by the Hebei Spirit in Two less familiar countermeasures -- bioremediation agents and dispersants -- were used during the response to this spill.
Two locally available natural materials were used for remediation of water from oil spill. Youda and Masoofa were used and the oil sorption capacities were gram of oil per gram of sorbent for Youda and gram of oil per gram of sorbent File Size: KB.

They suggested that the sorption capacity of the oil is inversely proportional to the oil viscosity and directly proportional to the capillary radius. At the same time, the viscosity increases the adherence of oil onto the surface of the fiber and within the capillary during by: Additional Physical Format: Online version: Neaves, W.M.

Oil sorbents comprise a wide range of organic, inorganic, and synthetic products designed to recover oil in preference to water.
Their composition and structure depend on the material used and the intended application in the response (ITOPF, ).Sorbents bind oil via absorption, adsorption, or a combination of both mechanisms, without the formation or breakage of Cited by: Oil spills are a global concern due to the environmental and economical impact.
Various commercial systems have been developed to control these spills, including the use of fibers as sorbents. However, most sorbents end up in landfills or in cineration after single by: This chapter discusses oil spill dispersants.
The prime purpose of using dispersants is to reduce the impact of oil on shorelines. To accomplish this task, the dispersant application must be highly successful. The second purpose of using dispersants is to reduce the impact on birds and mammals on the water : Merv Fingas.

Oil-sorbent plays an important role in many fields such as oil spill cleanup, oil/water separation and environmental remediation (Gui et al.,Yuan et al.,Su et al.,Whitfield,Moura and Lago,Fingas,Adebajo et al., ).Disasters such as the oil spill in Mexico Gulf in remind us again the importance of oil-sorbents in spilled oil Cited by: In the recent decades oil spills in the aquatic environments are one of the major sources of environmental pollutions, which are steadily growing with the increase in oil consumption.
