| 20100320151 | METHOD FOR COLLECTING OR CONTAINING AN OIL SPILL - Oil in an oil spill is collected by laying an elongate generally flat mat onto and around the spill where the mat is formed from strips of material arranged side by side and connected at spaced positions longitudinally to define a honeycomb structure with top and bottom surfaces of the mat defined by edges of the strips. The mat is unrolled from a supply and laid onto the surface of a body of water in which the spill has occurred so that open empty tubular cells stand upwardly from the surface allowing the oil to be absorbed into the cells. The oil can be squeezed out by pressing the strips together to close the cells. | 12-23-2010 |

| 20140076815 | SEPARATION OF OIL DROPLETS FROM WATER - A treatment process for an aqueous phase which contains oil droplets, possibly of 10-50 nm diameter, in aqueous flow from a hydrocyclone separator, comprises bringing the water into contact with a surface subdivided into areas of differing surface energy and affinity for oil and such that when the surface is submerged in an aqueous phase, oil droplets adhere to it with an apparent contact angle in a range from 90 to 150 degrees. Areas of the surface may reduce their affinity for oil in response to an external stimulus causing controlled release of droplets adhering to the surface. The process may be used to remove oil droplets from water produced by an oil or gas well, after downhole oil water separation or after production at a at a well head, or used to coalesce droplets in such water to a larger size to enable conventional separation. | 03-20-2014 |
