Study Of Equipment And Methods For Removing Oil From Harbor Waters

Abstract

A cost effectiveness analysis was performed for equipment, materials, and techniques for the removal of spilled petroleum products from the surface of port and harbor waters used by U. S. Naval craft. Effectiveness criteria, formulated for present methods and presently available equipment and materials, included speed of application, completeness of removal, ease of operation, effect on marine life, operating continuity, and availability. Parameters for the effectiveness study were based on the petroleum products now in use or those planned for future use and a detailed review of the geographic, hydrographic, physical, and environmental characteristics of ports used by the U. S. Navy. The two most cost-effective systems for broad application were found to be mechanical recovery of spilled material by surface suction devices, supplemented by mechanical containment, and the application of chemical dispersants by pier-or vessel-mounted high pressure spray equipment.

Oil sorption behavior of various sorbents studied by sorption capacity measurement and environmental scanning electron microscopy

“…Even though no single system is likely to be completely effective, the use of an oil sorbent is one of the most widely used methods for combating oil spills in the sea (Walkup et al, 1969). Polypropylene fiber is one of the most commonly used sorbents in oil spill cleanup because of its oleophilic and hydrophobic characteristics (Schatzberg, 1971).…”

“An Inevitable Consequence:” Changing Ideas of Prevention in the Wake of Catastrophic Events

“…31 A later presentation would show that existing methods could not withstand 2-foot waves and 20 mile per hour winds. 32 Haxby's statement reflected that the oil companies did not fully understand the oil-water interface, nor did it understand how to develop standard laboratory and field methods to test the emerging CDR technologies. The oilwater interface remained researchers' most vexing challenge.…”

Present Advancement in Production of Carbon Nanotubes and Their Derivatives from Industrial Waste with Promising Applications

“…Spreading would increase the oil covering surface area which would prevent the exposure to the sunlight and air, resulting in serious collapse of the eco-system. Therefore, development of effective adsorbent technology for handling such problem has gained an increasing interest from many research teams in many countries (Walkup et al, 1969;IPIECA, 1991;Albert, 1997;Wei and Molloy 2003;White and Molloy, 2003;Wang et al, 2007;Ren et al, 2011;Liu et al, 2015).…”
