Abstract

Elaboration of effective ways of elimination of spilled oil and oil products are very actually now. One of the most effective methods for solving this problem is the absorption of the oil by sorbents. Supersorbent on the basis of thermally expanded graphite has unique characteristics. It is a special modification of the graphite obtained by multi-stage thermo-chemical treatment of natural flakes graphite. We have developed different methods of preliminary preparation and subsequent application of this sorbent considering a specificity of emergency spill, properties of spilled liquid, the nature of cleaning surface and weather conditions. Also, question of spent sorbent utilization has been studied. The recycling process involves the desorption process up to 85% with subsequent use of the sorbent to 10 cycles of regeneration. Obtained while desorption liquid can be used for another purpose or as an additive to fuel oil. Technology and equipment for liquidation of emergency oil spills on water surface and coastal sand have been developed and tested.
