The embodiment of the present disclosure provides a recovery device for oil spilling on water, a control method thereof, and a recovery vessel. The recovery device includes a casing, a control center, a variable pressure airbag, an oil detector, an isolation layer, a water suction pump, and a drain pipe. The casing is of a hollow structure, the hollow structure is used to accommodate an oil-water mixture and used as a temporary oil collection tank, the upper part of the casing is provided with an oil-water mixture inlet, the bottom of the casing is provided with a drain port, and the side wall of the casting is provided with an oil suction port. The variable pressure airbag is arranged outside the casing, and the variable pressure airbag is configured to adjust buoyancy of the recovery device. The water suction pump is configured to pump out water in the casing and discharge water to a water environment outside the casing through the drain pipe. The control center is arranged on the casing for controlling the volume of the variable pressure airbag and the startup and shutdown of the water suction pump.

There is provided an oil absorbent pad for cleaning oil on a surface having an oil absorbent body having an upper surface and a lower surface, the body being formed from fiber recovered from recycled tires, and at least one of the upper surface and the lower surface is an outermost layer of the oil absorbent pad.

The invention provides a coating which exhibits fast oleophobic-hydrophilic switching behaviour with, for example, equilibration of high oil contact angle (hexadecane=80) and low water contact angle (<10) values which occur within 10 s of droplet impact. These optically transparent surfaces display excellent anti-fogging and self-cleaning properties. The magnitude of oleophobic-hydrophilic switching can be further enhanced by the incorporation of surface roughness and in one embodiment the coating is applied to a surface in the form of a mesh in order to form an effective filter.

A method and apparatus for processing waste water generated during oilfield drilling operations with a mobile processing unit utilizing heat energy sourced from burning hydrocarbon fuel directly and/or capturing and using the exhaust heat energy generated by burning hydrocarbons in engines such as diesel engines in order to vaporize a dominant mass of the aqueous phase of the waste water while clarifying the heat source combustion gasses. The water vapor generated by the vaporization process may be discharged directly to the atmosphere or alternately condensed and captured for use as potable water. The residual waste water is thereby concentrated and the cost to dispose of the waste water is greatly reduced.

Disclosed herein are aggregators that can be cellulosic particles having high oil sorption capacity, high hydrophobicity, high buoyancy in water, and an aggregation quality that can support environmental remediation of hydrocarbon spills (e.g., crude oil spills) by various cleanup strategies including burning, skimming, or bioremediation. Also disclosed are methods of making the materials and methods of using the materials for environmental remediation

The present invention provides improved methods for purifying and/or removing oily particles, and/or contaminants suspended or dissolved in water. In particular the process relates to an additive composition that has the appropriate surfactant characteristics for effectively removing an oil phase from an oil/aqueous mixed phase via foam fractionation. According to the invention, a hydrophobically modified polymer that acts as an associative thickener is combined with surfactant in appropriate ratios to facilitate oil removal for water purification in any of a number of commercial, environmental and industrial applications.

An oil-collecting apparatus includes: a body including an inlet through which a liquid is introduced, a first outlet through which purified water generated from the liquid introduced through the inlet is discharged, and a second outlet through which materials collected from the liquid are discharged; and a filter arranged at the first outlet of the body and generating the purified water by collecting the materials included in the liquid by allowing the liquid introduced through the inlet to pass therethrough.

A flexible thermoplastic tube having a stiffening member installed inside is described herein. Mechanisms to couple both the stiffening member and outer tube are also described. The stiffened tube is particularly useful in oil skimming equipment for remediation of hydrocarbons in containment pools.

The present disclosure relates to a fence having a hydrophilic material, and according to an embodiment of the present disclosure, there is an effect in collecting oil or hazardous & noxious substances quickly and efficiently while minimizing the pressure caused by water, by forming the fence from a material that allows water to penetrate while disallowing oil to penetrate.

Additionally, there is an effect in preventing oil spill phenomena caused by damage or unbalance of the fence by reducing the water pressure applied to the fence due to water penetration even when a strong water pressure acts on the fence, for example, strong tidal currents occur and the fence is towed at high speeds to collect oil.

An oil skimming device for the removal of oil located at the surface of a body of water includes a float, at least one skimming surface, a sorbent material, at least one scraper, and a motor. The float is arranged such that the device rests on the surface of the body of water from which the oil is to be removed. The at least one skimming surface is rotatable about an axis such that when the device is floating in the water a portion of the ridged skimming surface is above and a portion of the skimming surface is below the water surface. The sorbent material is removably attached to and substantially covers the skimming surface. The sorbent material is configured to rotate with the skimming surface and to sorb oil as the skimming surface is rotated.
