Investigation of organic materials nature on petrol removal from water surfacee

Abstract

The properties of some organic materials in the removal of oil from water area were studied. It was shown that available materials as technical wool and sintepon can be used as effective sorbents for petroleum removal from water area. The sample mechanical wringing of these sorbents permits to return the part of adsorbed oil for its next use. The dependence of sorption properties (the adsorbed petroleum mass, specific oil adsorption, return of the oil and selectivity of petroleum removal) and petroleum removal from the number of absorption-release cycles was established. It was established that quantity of adsorbed oil decreases in other next step of removal but mass of oil returned increases in the process of mechanical wringing. The regeneration of these adsorbents by flushing in gasoline permits to obtained the initial properties in oil removal from water area. The sorption elements in the form of bags from linen with these materials were prepared. The dependence of the amount of oil removed by these sorption elements from the time of oil clearing of the water area process was determined and the optimal parameters of petroleum removal were established. It was shown that sorption elements on the base of these materials have adsorption capacity equal to 14-16 g of petroleum/g sorbent at selectivity of petroleum removal more than 70 % and oil recovery degree more than 80 % and the possibility their reusable use on oil spill response. The obtained positive results of oil removal from water area permit to propose in extreme cases of oil spills the available industrial products as jerseys, blankest, jackets etc. use successfully for petroleum spill response. The hydrophobization of these elements permits to improve their properties in oil removal from water area. As results of sorption elements modification the increase of adsorbed oil mass and specific petroleum removal at simultaneous increase of returned oil quantity for its next use and oil removal selectivity were established. It was established that synthesized sorption elements not inferior in properties known industrial sorbents for oil removal from water area.
