Sorbent for Liquidation of Oil Spills Based on Polyurethane Foam and Polysterene Foam Wastes
https://doi.org/10.18412/1816-0395-2015-4-42-46
Abstract
The possibility of using the sorbent obtained based on elastic and semielastic polyurethane foam and polysterene foam wastes as the oil-absorbing material is
investigated. To fabricate the sorbent, we selected open-porosity polyurethane foam as the base in view of the fact that the waste filler of polysterene foam has
closed pores and is not good sorbent. We also used 10-% by weight filling with polysterene foam in a form of crumb with fractions of 2 – 3 and 4 – 5 mm. We evaluated
the oil capacity of the sorbent depending on the crumb size. Due to the presence of closed-porosity polysterene foam in the structure of the sorbent, it possesses
high floatability and high sorption rate of ~15 min. The use of the prepared sorbent makes it possible to solve simultaneously two environmental problemsthe
liquidation of spills of oil products and utilization of wastes of the foam polysterene packing material.
