An oil boom skimmer member for oil spill recovery, in particular for collecting oil from a water surface, has a skimmer arrangement integrated into an oil boom member. An oil recovery system, in particular for collecting oil from a water surface, includes a plurality of such oil boom skimmer members connected in series to form an oil spill recovery boom apparatus. A guiding boom is connected to each of the outermost oil boom members, and the guiding booms are also connected to a vessel for operating the system. Through the use of trawl technology the skimmer oil boom apparatus can be operated by only one vessel when needed.

A system for collecting matter provides a low energy, low cost and nearly zero pollutant process for extracting suspended and/or dissolved matter in a medium. The system collects the matter on a material which is deployed into the medium, and the matter is extracted off the material. If the extracted matter is algae, then it can be processed into end user commercial products such as pharmaceuticals, nutraceuticals, cosmetics, biofuels, food products, crop fertilizer, animal feed and polymers. If the extracted matter is oil or bitumen, then it can be recovered at oil spills or in tar sands. If the medium is infected with a harmful algae bloom of cyanobacteria, then the system could not only harvest the algae for processing but also cut off a food source of remaining algae by additionally extracting suspended silt. This invention collects matter in an economically and environmentally viable manner.

An oil-based article absorbs oil-based fluid on a surface. The article is made of a cloth and a flotation material encased in the cloth to assist in the absorption of oil-based fluid and the flotation of the article. The cloth has at least one napped surface that defines voids therein, and nap is formed of raised ends or loops of the fibers and has a thickness. The flotation material can also absorb water. When encased in the cloth, the cloth inhibits water absorption to inhibit water from contacting the flotation material. Thus, the flotation material absorbs oil-based fluid to increase the absorption capability of the article. The oil-based fluid containing flotation material is capable of assisting flotation. The oil-based fluid is recovered from the article and put to a beneficial use. The article can be reused repeatedly.
摘要:
A method for collecting from a surface area crude oil or a similar highly viscous, tough and tacky material which covers the surface area as a layer, is characterised by consecutively separating volumes of the layer by means of a curtain of a fluid which under pressure is driven into the layer and has been heated to a temperature capable of lowering the high viscosity of the material in the volume, and applying suction to the material in the volume thus made low-viscous, for removing this volume of material from the area. A suction nozzle for carrying out this method has a suction channel (1) which is connectible to a suction conduit, a pressure fluid chamber (6) which has pressure fluid inlets and a first pressure fluid outlet (8, 9) surrounding the intake end of the suction channel.
摘要:
The present invention relates to an apparatus for removing water contaminants and, more particularly, to an apparatus for removing water contaminants, in which when water contaminants, such as oil, green algae and red algae, are generated on the water surface, the apparatus sucks in the water contaminants, passes the sucked in water contaminants through an absorbent paper in order that the water contaminants are absorbed by the absorbent paper, and makes the absorbent paper roll periodically or continuously, thereby maintaining the absorbability of the absorbent paper contaminated by the water contaminants. The apparatus for removing water contaminants, such as oil, green algae and red algae, according to the present invention comprises: a suction pipe for sucking in the water contaminants from an inlet; a suction pump connected to the suction pipe for sucking in the water contaminants from the inlet to the outlet side of the suction pipe; and an absorbent paper installed at the periphery of the inlet of the suction pipe, wherein the absorbent paper is installed to be movable in the inlet and absorb the water contaminants.
摘要:
A multipurpose tool (1) for oil spill control, preferably offshore, comprises a remotely controlled telescopic arm (5) having a first end (6) and a second end (7). The first end (6) is mounted on a vessel (25) and the second end (7) is provided with a quick-release coupling (8) for the fitting of various replaceable nozzles (15) thereto. The various replaceable nozzles (15) are connected to one or more hydraulic tubes (20) and tubes for supplying oil spill control agents and recovering collected oil.
