Abstract
The present invention relates to an oil-gathering agent composition for oil spill. The oil-gathering agent for diesel oil spill comprises of (wt%) 1%-10% of natural carboxylic acid and 90-99% of alcohols or kerosene organic solvent, and the oil-gathering agent for crude oil spill is composed of (wt%) 1%-10% of natural carboxylic acid and polyoxyethylated oleate and 90-99% of said organic solvent. Said invention is simple in preparation, convenient for use, low in cost and good in oil-gathering effect.
Description
The present invention is 95112179.0 with the dividing an application of title application, and original application day is 95.10.27.
The present invention relates to a kind of oil-collecting agent that is used for marine oil overflow, belong to the chemical composition technical field.
The oil spilling that offshore oil exploitation and transportation usually cause because of accident or other technologies reason, this not only causes enormous economic loss to enterprise, but also can cause serious environmental to pollute.Processing to oil spilling generally has physics method, chemical method and the combination of the two.The physics method uses mechanical fence with the oil spilling corral, with sorbent material or pump oil spilling is reclaimed again; Chemical method adopts oil-treatment agent that oil spilling is carried out chemical treatment, and then row reclaims.Oil treatment comprises oil-collecting agent, sinking agent, peptizer, emulsifying dispersant etc.After the marine oil overflow accident took place, normal conditions were to be that very fast diffusion is carried out at the center with the accident spot, will cover areas tens thousand of or thousands of square metres in several hours.Form the oil spilling layer that thickness is about 0.1mm in seawater surface, be difficult to reclaim with general physical or chemical process.So the processing top priority of marine oil overflow is to prevent the oil spilling diffusion, be convenient to further remove and reclaim.Adopt mechanical fence with the method for oil spilling trap in certain zone, its equipment complexity operate cumbersomely, and will finish in the very short time after the accident generation generally is to be difficult to realization for this reason, and the oil-collecting effect is undesirable.Oil-collecting agent based on tensio-active agent, can reduce the surface tension of seawater, form insoluble monolayer in seawater surface, when it is sprawled pressure and presses greater than sprawling of oil, just produce the reactive force of an inhibited oil diffusion, make oil spill area that the trend of dwindling be arranged, and control the diffusion of oil spilling effectively, this effect is referred to as chemical fence.Dwindle and to keep a few hours though pasta is long-pending, won valuable time for using mechanical fence or mechanical treatment.The general consumption of oil-collecting agent seldom, it is very fast to take effect, and become to use other chemical agents, and the physics method is handled the necessary prerequisite of oil spilling.
Nineteen forty-three United States Patent (USP) U.S.Pat.2,447,551 disclose a kind of oil-collecting agent, major ingredient is the oxyhydroxide of liquid aliphatic acid esters and sugar and sugared derivative, requirement does not have clear and definite effect being lower than 40 uses down, and this has limited the practical application of this oil-collecting agent widely.United States Patent (USP) U.S.Pat 3 in 1974,810,835 disclose some oil-collecting agent, are tensio-active agent with alkylamide, alkyl glycol, thiazolinyl ethylene glycol, alkyl propylene glycol ester, alkyl acid polyoxyethylene glycol ester etc., are equipped with ethoxy ethanol, two acetaldehyde, Virahol equal solvent.Its experiment is carried out in fresh water, does not relate to holding time of compression oil film, and raw materials used more expensive, and is unsuitable practical.
Japan's " technological development of public hazards countermeasure " is magazine (1976 (P.P.M), 5,1-30) delivered and obtained " marine oil overflow processing " literary composition that a former virtue is shown, chemical processing agent has wherein used two kinds of tensio-active agents of polyvinyl alcohol, glycerol mono-laurate of butter fat, experimental result is that the crude oil oil spill area dwindles about 70%, have only 2.5 hours but hold time, and this treatment agent price is expensive, is unsuitable for practicality.At China's " marine environmental sciences " magazine (1986,5 (4), 58) delivered " the marine oil overflow treatment agent " of works such as Liu Chunhua on, 47 kinds of tensio-active agents estimated in article, think that can be used for the oil-collecting agent has five kinds: span-20 (sorbitan mono-laurate), span-80 (sorbitan monooleate), oleyl alcohol, tallow fatty acid-polyoxyethylene glycol, the glycerol mono laurate.This article does not provide concrete application example, and the oil-collecting effect is also had no way of as can be known.In sum, also do not have a kind of ideal at present, inexpensive makes known publicly with effective oil spilling oil-collecting agent.
The objective of the invention is to remedy the deficiency of prior art, a kind of convenience, cheap, diesel oil or crude oil oil spilling oil-collecting agent efficiently are provided.
Oil-collecting agent constituent prescription of the present invention is as follows:
I. the oil-collecting agent component A that is used for the diesel oil oil spilling: the natural carboxylic acid, (25 ℃) are brown viscous liquid under the room temperature, purity＞95%.Can from
The Vegetable oil lipoprotein tankage extract with ordinary method.Component B: alcohols or kerosene organic solvent, technical grade.
Wherein, A component 1～10% mass percent, B component 90～99% mass percents.With A component 3～5%, B component 95～97% is good.
II. be used for the oil-collecting agent of crude oil
Component A, B are the same, and increase component C: polyoxyethylene oleate, wherein the mole number of oxyethane is 400～800, can be expressed as P (EO)
400～800Oleic acid ester, this component normal temperature and pressure are liquid down, and the purity requirement technical grade gets final product.
Concrete proportioning is:
A: C=(3～5): (3～5) (mass ratio), (A+B) two component mass percents are 1～10%, B component 90～99%.With (A+B)) two components are 3～5%, the B component is 95～97% for good.
Earlier component A and C are mixed in proportion, add a certain proportion of solvent B then.
Consider factors such as cost and pollution, component B is best with ethanol, and C is with P (EO)
400Oleic acid ester is best.
Methods such as conventional stirring, dissolving are adopted in the preparation of the present composition, and finished product is stable homogeneous solution, is light brown.
Present composition I. is used for the oil-collecting of marine diesel oil oil spilling, under conditions such as different temperature, salinity, PH, oil reservoir is shunk rapidly in the short period of time, dwindle area to reach more than 70%, and keep interface stability and reach more than 6 hours environmentally safe.Present composition II. is used for the oil-collecting of marine crude oil oil spilling, under conditions such as different temperature, salinity, PH, all can dwindle more than 55% making the oil reservoir area in the short time, and keep interface stability more than 6 hours, same environmentally safe.
