Problems solved by technology

Adsorbent is a good technology to deal with oil spills. However, for large-scale oil spills, a large amount of adsorbent is often required, and after the oil is absorbed by the adsorbent, it needs to be recovered through desorption. More processes and higher cost

preparation example Construction

[0032] The preparation method of the SiFast-332 is as follows:

[0033] Get 5-40 parts of sodium dodecyl perfluorosulfonate, 5-65 parts of polysiloxane compound with the following structural formula,

[0034]

[0035] Then mix it with 10-50 parts of alcohol containing 1-4 carbon atoms and 10-40 parts of water, heat and reflux at 50-70°C, stir evenly for 2-4 hours until the reaction liquid is transparent, and cool to room temperature to prepare.

[0036] The sodium decanyl perfluorosulfonate was purchased from Harbin Xuejia Fluorosilicon Co., Ltd.; the polysiloxane compound was purchased from Qingdao Xingye Organic Silicon New Material Co., Ltd.

[0037] Preferably, 15 parts of sodium dodecyl perfluorosulfonate and 25 parts of the polysiloxane compound shown in the following structural formula,

[0038]

[0039] Then mix it with 30 parts of ethanol and 40 parts of water, heat to reflux at 50°C, and stir evenly for 4 hours until the reaction liquid is transparent, then co...

Embodiment 1

[0044] Take 80g of crude oil, spread it in a circular tank with a diameter of 35cm, and add 4L of seawater. Immerse the oil-absorbing felt of 1.5cm×1.5cm×0.3cm in the oil spill flooding agent SiFast-332 prepared according to the above-mentioned preferred scheme diluted 10 times (the amount of the oil-absorbing felt absorbing the diluted oil spill flooding agent is 0.5g) , take it out, and put it in the center of the above-mentioned round groove covered with oil. The oil surface shrinks rapidly to the edge of the circular groove, and the oil displacement area reaches 95%. The enriched oil was recovered with a peristaltic pump, and the recovery rate reached 92%.

Embodiment 2

[0046] Take 80g of crude oil, spread it in a circular tank with a diameter of 35cm, and add 4L of seawater. The oil-absorbing felt of 1.5cm×1.5cm×0.3cm is immersed in the oil spill flooding agent SiFast-332 prepared according to the above-mentioned preferred scheme diluted 20 times (the amount of oil spill flooding agent absorbed by the oil-absorbing felt is 0.5g) , take it out, and put it in the center of the above-mentioned round groove covered with oil. The oil surface shrinks rapidly to the edge of the circular groove, and the oil displacement area reaches 88%. The enriched oil was recovered with a peristaltic pump, and the recovery rate reached 91%.

Abstract

The invention discloses a method for recovering spilled oil in a water area. The method utilizes a material which adsorbs a spilled oil displacement agent and has the density less than the density of water to realize spilled oil displacement and collection. In the invention, materials adopted by the method float on a water-oil interface and the spilled oil displacement agent is continuously and slowly released from the materials to the intermediate part of the water-oil interface, and thus spilled oil displacement agent efficacy can be maintained for a long time and can be displayed at the maximum degree; spilled oil displacement agent waste is reduced; and spilled oil displacement agent effects are improved. The method can improve a spilled oil recovery rate, and has large application values in treatment on spilled oil in a water area.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a method for recovering oil spilled in water areas. Background technique [0002] In recent years, oil spills and oil spill accidents have occurred continuously in various countries, and various oil pollution incidents are on the rise, causing immeasurable economic losses and environmental hazards. According to statistics, oil and petroleum products leaked into the ocean through various channels account for about 0.5% of the world's total oil production every year. Therefore, how to adopt new technologies to solve water pollution caused by oil leakage and effectively recover precious resources such as leaked oil It has become a major issue that countries all over the world pay attention to. [0003] When oil spills occur in waters, especially crude oil, the oil will spread rapidly on the water surface, affecting more and wider areas, causing serious pollution ...
