International Classification:

C08L 5302

US Classification:

525 97, 525 98, 525 99, 210924, 588900, 588901

Abstract:

An oil-sorbent composition of matter has bound combinations of styrene-butadiene-styrene (SBS) and ethylene propylene diene monomer (EPDM). The SBS, or both materials, may be in the form of multitudes of granules. In certain preferred embodiments, the combination is 10-30% by weight and the SBS is about 30% styrene and manufactured without talc. The composition of matter can be formed into a solid, compliant body and utilized in a product for absorbing oil. The body can be formed, in one preferred embodiment, into an extended cylinder having an axial hole.

US Classification:

210693, 210923, 210924, 210925, 2105021

Abstract:

One or more water- and oil-porous containers or sacks are made of a pair of mesh sheets affixed together and stiffened around their perimeter. The sacks can be partially filled with a multitude of tubular bodies made of an oil-entrapping polymer, which have their longest dimension parallel to an axial hole. A preferred material is composed of a combination of SBS and EPDM, formed by an extrusion technique, to create highly fissured generally cylindrical bodies. The sacks may be deployed in areas where oil is floating on water, such as where oil has spilled from tankers on oceans, seas, lakes, or rivers. When the bodies are afloat, oily water can pass through the axial holes of and around the bodies, maximizing the surface area contacted by the oil and minimizing gel blocking. After a time sufficient for the bodies in the sacks to adsorb oil, the sacks can be collected. Various deployment and collection methods are disclosed.

International Classification:

E02B 1504

US Classification:

210693

Abstract:

A plurality of water- and oil-porous sacks are partially filled with a number of generally toroidal bodies of a polymer material that entraps oil and including mesh fragments scattered throughout the bodies. Each sack is sewn with a perimeter stiffening ring, to retain a flat profile, and has a netting that closes to help inhibit outflow of the oil when the sack is retrieved. When deployed from ship or by air onto a spill, the sacks spread into a pancake shape and the polymer matter forms a single layer that retains the oil. The inventive sacks will float indefinitely without releasing the oil or allowing it to emulsify, so the oil can remain in place until collection efforts are feasible. The sacks can be burned in situ, or standard fishing boats or specialized collection boats can be used to retrieve the sacks, and the collected material can be burned to capture the energy content of the oil or processed to separate the oil from the polymer. The inventive sacks can be used in conjunction with other, known containment or retrieval equipment, such as booms or skimmers.
