Problems solved by technology

Traditional methods (oil dispersants, oil-absorbing sponges, dispersants, microbial enrichment oxidation, and combustion) cannot be treated in an environmentally friendly and effective manner. Oil dispersants treat oil slicks so that the chemical oil that sinks into the seabed continues to pollute the seabed environment. ;Oil-absorbing sponges are quite effective for light oil products, but helpless for heavy oil products; the use of dispersants, microbial eutrophication and combustion not only brings secondary damage or pollution to the marine ecological environment, but also wastes increasingly scarce energy oil products

Abstract

The invention discloses an oil gelling agent for treating oil spill on the sea. The oil gelling agent is lightweight inorganic powder prepared by performing flame-spraying and surface hydrophobic modification on inorganic ceramic particles, the apparent density of the lightweight inorganic powder is 0.1-0.95g / cm<3>, and the particle size of the lightweight inorganic powder is 1-20 micrometers. The oil gelling agent can safely, fast and simply recycle leaked low-coagulation chemical oil such as gasoline, diesel oil, crude oil and marine diesel oil.

Description

technical field [0001] The invention relates to the technical field of environmental protection treatment of marine oil spills, in particular to an oil-condensing agent for treating floating oil in the sea. Background technique [0002] Regarding the oil spill accident at sea, you don't need to be there personally. You can see the struggling seabirds on TV, and you can know how much the oil slick on the sea has harmed the marine ecosystem and the marine environment. Therefore, the best way is to reduce the leakage accidents on the sea surface that lead to the formation of oil slicks. Although there are stricter punishment measures for oil spill accidents, the leakage situation has been greatly reduced. Unfortunately, the oil slick at sea has not been completely eliminated. On average, tens of thousands of tons of chemical oil are still dumped at sea every year. Moreover, supertankers are not the only danger of oil slicks at sea. Offshore drilling platforms, underwater oil ...
