Material for oil spills removal

Oil spills do  irretrievable harm to environment and damage the oil companies and petroleum industries. Oil spills in coastal and inland waters are especially dangerous, as oil spreads rapidly on the water surface, forming a thin film  which destroys the ecosystem of coastal waters and shorelines.

Nanofibrous nonwovens are used for:
  • collecting of thin films of oil and petroleum from water surfaces
  • creation of sorptive barriers around a production machinery
  • isolation of a coastline, harbor facilities, etc. from contamination by oil and petroleum products
 
Specification

* Materials may be also produces in the form of tapes and pads/ napkins up to 2000 m in length
and a width of 1600mm with the same sorption capacity
** Determined by the type of a polymer, fiber diameter and a surface density

Advantages of the materials:
  • High absorption capacity – up to 40 g / g (2-7 times higher than that of analogues on the market) and up to 1500 g for 1 m2 of the material
  • Selective sorption of hydrophobic liquids - oil and petroleum products, but not water
  • Buoyancy in water
  • High-speed processing of an oil spill
  • Highly efficient recovery of oil and petroleum products from the collected oil spill – up to 95%
  • Reuse of the collected oil
  • After the proper use of the material it can be recycled and used again (for example in a road construction sphere)

 

Application method for cleaning water surfaces from oil thin films
  1. In case of water contamination an oil slick is to be covered with the adsorptive material
  2. Cleaning takes place via a continuous conveyor technology: while one part of the nanofiber fabrics absorbs the oil from the water surface, the other, having already adsorbed a sufficient amount of oil, is being squeezed out
  3. Important advantage – the collected oil can be re-used The material can be used in special oil recovery devices – skimmers – in preference to traditional nonwovens
