Oil Slick Removal Using Matrices of Polypropylene Filaments

Abstract

Use of matrices of polypropylene filaments in the removal of oil from the surface of seawater was investigated. The data indicated that the distance between the filaments and the cross-sectional area of the filaments was an important factor in the observed removal capacity of the matrices. An increase in the turbulence level of the slick surface markedly decreased the oil retention capabilities of the matrices. At similar interfilament distances, changes in the filament geometry from circular to rectangular led to much higher oil retention capacities while changes in the surface properties of the filaments appeared to have a minimal effect on the observed capacities.

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

“…The ESEM observation made during the given time interval and analysis of micrographs indicated that the oil on the left migrated to the oil drop on the right position. Considering the high degree of crystallinity of PP sheath fiber, absorption into the fiber is less likely as pointed out by previous studies (Zahid et al, 1972;Fig. 13.…”

A review of polymer nanofibres by electrospinning and their application in oil–water separation for cleaning up marine oil spills

“…The increased sorption happened due to the adherence of the oil to the fibre's surface whereas the decreased sorption occurred when oil is inhibited from penetrating the interior of the fibre (Ceylan et al, Choi and Moreau, 1993;Wei et al, 2003;Zhu et al, 2011). Here, it can be seen that macroporous materials play an important role to determine the sorption capacity for oil of different viscosity (Ceylan et al, 2009;Zahid et al, 1972;Zhu et al, 2011).…”

Experimental Investigation of Oil Spill Cleanup Using Cholan as a Natural Oil Absorber

“…Next, the Cholan pieces were lifted by a wire basket and allowed to drip freely for 1 min before being finally weighed. Previous researchers suggested this 1-min free dripping (Choi, 1996;Johnson et al, 1973;Radetić et al, 2003;Zahid et al, 1972). Cholan was centrifuged in order to separate the water and oil.…”
