Problems solved by technology

Although the surfactant used is rhamnolipid, it is not ideal in terms of dispersion and emulsification
And the use of yeast preservation and fermentation methods is limited in scale and ineffective
[0004] But the oil spill dispersant that exists in the prior art is unsatisfactory in dispersing and emulsifying effect, so developing a kind of highly efficient, environment-friendly oil spill dispersant is the research key in the technical field

Abstract

The invention relates to a marine oil spill dispersant and a preparation method thereof. The preparation method comprises selecting an anionic surfactant and first, second and third nonionic surfactants, carrying out compounding, adding ethylene glycol monobutyl ether as a solvent and PEG as a stabilizing agent into the compound and carrying out compounding to obtain the marine oil spill dispersant. The anionic surfactant is rhamnolipid. The first nonionic surfactant is sophorolipid. The second nonionic surfactant is Tween-85. The third nonionic surfactant is span-80. The marine oil spill dispersant has a HLB value of 9.04-14.00 and kinematic viscosity of 4.97-5.68mm<2> / s.

Description

technical field [0001] The invention relates to the field of water body pollution prevention and control, in particular to a marine oil spill dispersant and a preparation method thereof. Background technique [0002] The vast majority of marine oil pollution comes from human activities, including ship transportation, offshore oil and gas exploration, and coastal industrial sewage discharge. Due to the uneven distribution of oil production areas and consumption areas, more than half of the world's annual oil production comes from oil tankers at sea. This has brought the threat of oil pollution to the oceans that account for 71% of the earth's surface, especially sudden oil pollution such as oil tanker collisions and offshore oil field spills. The damage to the marine ecosystem caused by marine oil pollution is irreversible. Oil floats on the surface of the sea and spreads rapidly to form an oil film. The formation of oil film hinders the reoxygenation of water bodies, affec...
