Abstract

PURPOSE: A condensed-type sea effluxed oil treating agent, its preparation method and a method for using the treating agent are provided, which agent is highly viscous, effectively disperses the W/O emulsion, and is low toxic. CONSTITUTION: The condensed-type sea effluxed oil treating agent comprises 12-34 wt% of ethylene glycol monobutyl ether; 40-60 wt% of a base oil; 8-28 wt% of polyoxyethylene; and 5-15 wt% of sorbitan monooleate. The preparation method comprises the steps of heating and stirring ethylene glycol monobutyl ether and a base oil; adding polyoxyethylene and sorbitan monooleate to the mixture; and maturing the mixture. The condensed-type sea effluxed oil treating agent is diluted with water by the ratio of 1:10 before used.

Description

Concentrated offshore oil treatment agent and its manufacturing method, and method of using the concentrated agent {METHOD OF MAKING OIL}

The present invention relates to a marine effluent treatment agent, and more particularly, to a concentrated marine effluent treatment agent having a low toxicity and high oil dispersion efficiency, and a method for producing the same.

Conventional effluent treatment agents come into contact with effluent oils such as oil to finely emulsify and disperse oil and diffuse them into seawater, thereby purifying petroleum and microorganisms by bacteria, evaporation and oxidation by sunlight, etc. The spilled oil was removed by promoting the back.

However, since the oil spilled on the sea forms a chocolate mousse, the above-described conventional dispersant does not emulsify and disperse. In particular, the dispersant has a disadvantage of destroying the marine ecosystem.

Accordingly, an object of the present invention for solving the above problems is to provide a concentrated offshore oil treatment agent having a low toxicity and high oil dispersion efficiency and a method of manufacturing the same.

Another object of the present invention is to provide a concentrated emulsion treatment agent and a method of using the same, which do not affect the marine ecosystem.

The present invention according to the first aspect for achieving the above object is heated and stirred with 12-34% ethylene glycol monobutyl ether and 40-60% base oil, followed by 8-28% polyoxyethylene And sorbitan monolate 5-15% was added and mixed, and then aged again to implement a process for producing a concentrated offshore oil.

More preferably, a method of diluting the concentrated dispersant and water in a ratio of 1:10 is used.

1 is a test report showing the results of the test of the concentrated dispersant prepared according to an embodiment of the present invention in the Korea Institute of Emulsification Testing,

2 is a test certificate of the performance test of the concentrated dispersant according to the present invention,

Figure 3 is a marine pollution control material, pharmaceutical type approval certificate of the concentrated dispersant according to the present invention.

Preferred embodiments according to the present invention will be described in detail. It should be noted that in the following description, only parts necessary for understanding the manufacturing method of the present invention will be described, and descriptions of other parts will be omitted so as not to obscure the subject matter of the present invention.

First, looking at the concept of the offshore oil treatment agent proposed in the present invention, as a concentrated treatment agent prepared with a base oil and ethylene glycol monobutyl ether as the main component is excellent in the emulsion dispersion of high viscosity oil and W / O emulsion and low toxicity It is intended to propose a concentrated dispersant, a method for producing the same, and a method of using the same, which have a high oil dispersion efficiency and do not particularly affect the marine ecosystem.

Hereinafter, according to the present invention, the method for preparing and using the concentrated marine effluent treatment agent proposed above will be described in detail based on the preferred embodiment, but the present invention is not limited by the embodiment.

{Example 1}

Method for preparing concentrated dispersant .

22% ethyleneglycol monobutyl ether and 50% base oil were added and stirred at 50 ° C for 20 minutes, followed by 18% polyoxyethylene and sorbitan monooleate. ) 10% was added and mixed for 20 minutes, and then aged for 30 minutes to prepare a concentrated dispersant.

{Example 2}

Method of using concentrated dispersant .

The concentrated dispersant prepared according to the method of Example 1 described above was diluted with water at a ratio of 1:10, and then sprayed on the spilled oil to treat the spilled oil.

{Example 3}

Method of using concentrated dispersant .

After installing an oil fence to prevent oil from spreading on the surface of the oil spilled, the contaminated oil is recovered with an oil skimmer or sorbent emulsifier, and then the concentrated dispersant and water described above 1: After diluting at a ratio of 10, it was sprayed on the residue to completely remove the spilled oil.

On the other hand, the properties of the concentrated dispersant prepared according to the method of Example 1 are shown in Figures 1 to 3, and for reference, comparing the characteristics of the stock solution of the dispersant and the aqueous solution prepared by diluting it with Table 1 and same.

As described above, the present invention has an excellent effect on the dispersion of high viscosity oil and W / O emulsion emulsion, and also has a low toxicity and high oil dispersion efficiency, and particularly has a synergistic effect to preserve the marine ecosystem.
