Problems solved by technology

[0004] However, due to the chemical surfactants used in existing dispersant products, such as fatty alcohol polyoxyethylene ether, sodium dodecylbenzenesulfonate, etc., they will destroy the cell structure or metabolic enzyme activity of marine organisms, which are harmful to the ocean. The growth of organisms has high toxicity and poor biodegradability, so it is easy to cause secondary pollution to the marine ecological environment during use

Embodiment 1

[0022] Based on the total weight of the biological dispersant, it is composed of 3% sophorolipid, 9% rhamnolipid, 11% Tween-85, 2% span-80, 75% butyl glycol Ether composition, its pH value is 6.5-7.0.

[0023] The preparation process is to first mix sophorolipids, rhamnolipids, Tween-85, and Span-80 according to the above ratio, stir evenly, then add 10% of the total amount of ethylene glycol butyl ether, stir evenly, and then add 10% of the total amount of ethylene glycol butyl ether, stir well. Finally, add the remaining ethylene glycol butyl ether and stir evenly.

Embodiment 2

[0025] Based on the total weight of the biological dispersant, it is composed of 9% sophorolipids, 15% rhamnolipids, 26% Tween-85, 10% Span-80, 51% ethylene glycol butyl Ether composition, its pH value is 6.5-7.0.

[0026] The preparation process is to first mix sophorolipids, rhamnolipids, Tween-85, and Span-80 according to the above ratio, stir evenly, then add 16% of the total amount of ethylene glycol butyl ether, stir evenly, and then add 20% of the total amount of ethylene glycol butyl ether, stir evenly. Finally, add the remaining ethylene glycol butyl ether and stir evenly.

Embodiment 3

[0028] Based on the total weight of the biological dispersant, it is composed of 12% sophorolipids, 18% rhamnolipids, 20% Tween-85, 5% Span-80, 34% ethylene glycol butyl Ether composition, its pH value is 6.5-7.0.

[0029] The preparation process is to first mix sophorolipids, rhamnolipids, Tween-85, and Span-80 according to the above ratio, stir evenly, then add 20% of the total amount of ethylene glycol butyl ether, stir evenly, and then add 14% of the total amount of ethylene glycol butyl ether, stir evenly. Finally, add the remaining ethylene glycol butyl ether and stir evenly.

Abstract

The invention discloses a biological oil-eliminating agent capable of eliminating floating oil on the sea surface and a preparation method for the biological oil-eliminating agent. The biological oil-eliminating agent consists of the following components in percentage by weight:5 to 9 percent of sophorolipid, 10 to 16 percent of rhamnose, 15 to 20 percent of tween-85, 2 to 7 percent of span-80 and 48 to 68 percent of ethylene glycol butyl ether. The preparation method comprises the following steps: mixing and stirring the raw materials except for the ethylene glycol butyl ether uniformly according to the ratio; adding 10 to 20 percent of the total amount of the ethylene glycol butyl ether, stirring uniformly, adding 10 to 20 percent of the total amount of the ethylene glycol butyl ether again, and stirring uniformly; and adding the rest of the ethylene glycol butyl ether and stirring uniformly. The biological oil-eliminating agent can quickly eliminate the floating oil on the sea surface, effectively eliminates sea surface oil overflow pollution, and reduces the pressure of natural degradation. Compared with the conventional oil-eliminating agent products, the biological oil-eliminating agent obviously reduces the toxicity, obviously improves the biodegradability and reduces the secondary pollution caused by use of the oil-eliminating agent.

Description

technical field [0001] The invention relates to a technology for treating oil slicks on the sea surface, in particular to an oil dispersant for eliminating oil slicks on the sea surface and a preparation method thereof. Background technique [0002] With the acceleration of the process of global economic integration, offshore oil transportation and offshore oil extraction have increased rapidly, and marine oil spill accidents have also continued to increase, which seriously threatens the ecological environment of the ocean and coastal areas. On the one hand, oil spilled pollutants float and adhere to marine animals, plants, and even human body surfaces, causing toxic damage to organisms; on the other hand, oil spilled pollutants are ingested by marine organisms during the process of diffusion and dissolution , passing through the food chain or food web, will eventually affect the energy flow and material conversion of the entire marine ecosystem, threatening the living envir...
