Oil recovery system utilizing polyurethane foam: a feasibility study

Technical Report ·
OSTI ID:6647047
A system has been developed for recovering spilled oil from water surfaces under a wide variety of environmental conditions and for all types of oils. The system is designed to recover oil at rates up to 9000 gal/h. The system is based on the use of polyurethane foam, foamed on the job site, as a sorbent for the spilled oil. The foam is recirculated to increase efficiency and to lower unit costs. Equipment needed includes collection booms, and open-mesh chain-link belt for harvesting the oil-soaked sorbent, and a roller-wringer to remove oil and water from the foam. The foam is initially comminuted and distributed onto the water by means of a hay blower (mulcher), and recycled foam is distributed by an open-throat centrifugal blower. Recovered oil and water are transported to shore in large fabric bags for further treatment prior to disposal. Used foam is disposed of by incineration.
