Description
Den foreliggende oppfinnelse vedrører et materiale inneholdende overflateaktivt stoff og løsningsmiddel til dispergering av oljeflak. The present invention relates to a material containing surfactant and solvent for dispersing oil flakes.
Forurensning av havvann med olje (råolje eller fraksjoner Pollution of seawater with oil (crude oil or fractions
av råolje) forårsaket av ulykker, boreoperasjoner til havs, tøm-ming av ballastvann eller søl fra oljetankskip, noe som resul-terer i dannelse av en kontinuerlig film eller flak av olje, of crude oil) caused by accidents, drilling operations at sea, discharge of ballast water or spillage from oil tankers, which results in the formation of a continuous film or flake of oil,
som er tilbøyelig til å spres sammenhengende. Denne oljefilm er ikke ønskelig idet den danner en barriere mot overføring av luft og lys fra atmosfæren, noe som er absolutt nødvendig for å underholde livet i havet. which tends to spread coherently. This oil film is not desirable as it forms a barrier against the transmission of air and light from the atmosphere, which is absolutely necessary to sustain marine life.
En fremgangsmåte til å håndtere slike forurensningsproblemer er å anvende oljeoppsamlende materialer. De helles langs omkret-sen av oljeflaket, og de støter fra seg oljen som samles til en mer begrenset flate og kan fjernes ved vanlige mekaniske anord-ninger. Denne metode til komprimering av oljesøl er bare egnet ved forholdsvis rolig sjø. Dessuten er materialene bare effek- One method to deal with such pollution problems is to use oil-collecting materials. They are poured along the perimeter of the oil slick, and they repel the oil, which collects on a more limited surface and can be removed by normal mechanical devices. This method of compressing oil spills is only suitable in relatively calm seas. Moreover, the materials are only effective
tive i et meget kort tidsrom på grunn av materialenes løselighet i oljen. tive in a very short period of time due to the solubility of the materials in the oil.
En annen metode omfatter anvendelse av overflateaktive stoffer, som deler den sammenhengende oljefilm i små dråper og dispergerer dråpene i vannet til en dybde på flere meter under havflaten. Derved brytes filmen, og det foregår igjen en over-føring av luft og lys fra atmosfæren. Another method involves the use of surfactants, which divide the continuous oil film into small droplets and disperse the droplets in the water to a depth of several meters below the sea surface. Thereby the film is broken, and a transfer of air and light from the atmosphere takes place again.
Slike overflateaktive stoffer er meget effektive som dis-pergeringsstoffer for oljesøl, men deres anvendelse har resultert i sterk skade på marint liv, idet de er altfor giftige for flora og fauna i vann. Andre overflateaktive stoffer med lavere giftighetsgrad er meget ofte ineffektive som oljedispergeringsstoffer i åpent vann. Faktisk vasker vannet dem altfor hurtig ut av det oljeflak som de sprøytes på, med det resultat at oljedråpene flyter sammen eller reagglomererer og på nytt danner et flak. Such surfactants are very effective as dispersants for oil spills, but their use has resulted in severe damage to marine life, as they are far too toxic for flora and fauna in water. Other surfactants with a lower degree of toxicity are very often ineffective as oil dispersants in open water. In fact, the water washes them too quickly out of the oil flake on which they are sprayed, with the result that the oil droplets float together or reagglomerate and re-form a flake.
Av denne årsak anvender man vanligvis overflateaktive stoffer i blanding med et løsningsmidlets, særlig et løsningsmiddel med lav giftighetsgrad, såsom parafin- og cykloparafinhydrokar-boner samt lavere alkoholer. Anvendelse av et løsningsmiddel har mange fordeler. Det senker stoffets flytepunkt, det senker viskositeten til oljen som danner flaket, det funksjonerer som tynner for det overflateaktive stoff som lettere og mer homo-gent fordeles i oljeflaket, og det minsker det tidsrom som kreves for å blande dispergeringsmidlet og oljen. For this reason, surfactants are usually used in a mixture with a solvent, particularly a solvent with a low degree of toxicity, such as paraffin and cycloparaffin hydrocarbons and lower alcohols. The use of a solvent has many advantages. It lowers the substance's pour point, it lowers the viscosity of the oil that forms the flake, it functions as a thinner for the surfactant which is more easily and more homogeneously distributed in the oil flake, and it reduces the time required to mix the dispersant and the oil.
Et annet problem som oppstår ved anvendelse av overflateaktive stoffer som dispergeringsmiddel for oljesøl er deres vann-løselighet. Visse av disse stoffer løser seg for hurtig i vann og trenger således ikke inn i oljeflaket. Av denne årsak er det foreslått å anvende dispergerende materialer som inneholder minst Another problem that arises when using surfactants as a dispersant for oil spills is their water solubility. Some of these substances dissolve too quickly in water and thus do not penetrate the oil slick. For this reason, it is suggested to use dispersing materials that contain at least

to overflateaktive stoffer. Bedre dispergering blir følgen av anvendelse av blandinger åv overflateaktive stoffer, hvis propor-sjoner velges slik at den hydrofile-lipofile balanse (eller HLB) faller innenfor bestemte grenser. two surfactants. Better dispersion results from the use of mixtures of surfactants, the proportions of which are chosen so that the hydrophilic-lipophilic balance (or HLB) falls within certain limits.
Trenden er derfor å anvende blandinger av overflateaktive stoffer i blanding med et løsningsmiddel. Fra GB-patentskrift 1.404.684 er det kjent et slikt materiale, hvor oljeflakdisper-geringsmidlet omfatter en blanding av fettsyre-polyoksyalkylen-glykolestre og fettsyre-sorbitanestre (HLB for blandingen: fra 9 til 10,5), løst i et hydrokarbonløsningsmiddel som inneholder mindre enn 3 vekt% aromater. Løsningen kan inneholde fra 5 til 50 vekt% av blandingen av overflateaktivt stoff, hvorved en andel på 8-10 vekt% er særlig foretrukket. I andre patentskrifter er det beskrevet anvendelse av materialer som inneholder en fettsyre-sorbitanmonoester og et polyalkylenoksydaddukt av fettsyresorbitanmonoester (GB-patentskrift 1.255.394) eller som inneholder disse forbindelser i blanding med 25-35 volum% (eksklusive løsningsmiddel) av en 75 prosentig vannløsning av dialkylsulfosuccinatsalt (US-patentskrift 3.793.218). Det skal også vises til DE-utlegningsskrift 20 18 798, DE-patentskrift 21 60 698 hvor det omtales bruk av 50-95 vekt% hydrokarboner sammen med de overflateaktive stoffer, mens det ifølge GB-patentskrift 1 557 182 anvendes mer konsentrerte materialer som inneholder 40-80 vekt% dispergeringsmiddel og etre istedenfor hydrokarbon. De beste resultater ved dispergering av oljeflak oppnås ved hjelp av materialer som inneholder ca. 40% av en blanding overflateaktive stoffer og ca. 60% av et isoparafinhydrokarbonløsningsmiddel. The trend is therefore to use mixtures of surfactants mixed with a solvent. From GB patent 1,404,684 such a material is known, where the oil flake dispersant comprises a mixture of fatty acid polyoxyalkylene glycol esters and fatty acid sorbitan esters (HLB for the mixture: from 9 to 10.5), dissolved in a hydrocarbon solvent containing less than 3% by weight aromatics. The solution can contain from 5 to 50% by weight of the mixture of surfactant, whereby a proportion of 8-10% by weight is particularly preferred. Other patents describe the use of materials containing a fatty acid sorbitan monoester and a polyalkylene oxide adduct of fatty acid sorbitan monoester (GB patent 1,255,394) or which contain these compounds in a mixture with 25-35% by volume (excluding solvent) of a 75% water solution of dialkylsulfosuccinate salt (US Patent 3,793,218). Reference should also be made to DE explanatory document 20 18 798, DE patent document 21 60 698 where the use of 50-95% by weight of hydrocarbons together with the surfactants is mentioned, while according to GB patent document 1 557 182 more concentrated materials containing 40-80% by weight dispersant and ethers instead of hydrocarbon. The best results when dispersing oil flakes are achieved using materials containing approx. 40% of a mixture of surfactants and approx. 60% of an isoparaffin hydrocarbon solvent.
Anvendelse av et løsningmiddel har de ovennevnte fordeler, men visse problemer kan opptre når dispergeringsmiddelsblandinger spes med store mengder løsningsmiddel. Lagring av materialer som inneholder flyktige løsningsmidler kan øke brannrisikoen og føre til eksplosjoner. Nærværet av en stor mengde løsnings-middel i materialet innebærer at en lavere mengde overflateaktivt stoff finnes tilgjengelig for dispergering av oljeflaket. Dessuten kan visse flyktige komponenter i løsningsmidlet gå tapt ved avdampning når materialet påføres ved sprøyting på oljeflaket, særlig når materialet påføres fra et fly eller fra en båt på avstand, og de fordeler som oppnås ved innarbeidelsen av et løsningsmiddel i materialet går delvis tapt. The use of a solvent has the above advantages, but certain problems can occur when dispersant mixtures are mixed with large amounts of solvent. Storing materials containing volatile solvents can increase the risk of fire and lead to explosions. The presence of a large amount of solvent in the material means that a lower amount of surfactant is available for dispersing the oil slick. In addition, certain volatile components of the solvent may be lost by evaporation when the material is applied by spraying to the oil slick, particularly when the material is applied from a plane or from a boat at a distance, and the benefits obtained by the incorporation of a solvent into the material are partially lost.

<y>tterligere trekk ved materialet til dispergering av oljeflak fremgår av krav 2-10. Additional features of the material for dispersing oil flakes appear in claims 2-10.
Fettsyresorbitanmonoesteren er vanligvis en ester av en alifatisk monokarboksylsyre som inneholder 10-20 karbonatomer, såsom olje-, laurin-, palmitin- eller stearinsyre eller en blanding av disse syrer. The fatty acid sorbitan monoester is usually an ester of an aliphatic monocarboxylic acid containing 10-20 carbon atoms, such as oleic, lauric, palmitic or stearic acid or a mixture of these acids.
Polyalkylenoksydadduktet oppnås ved omsetning av en fettsyresorbitanmonoester med etylenoksyd og/eller propylenoksyd. Vanligvis inneholder adduktet fra 12 til 25 oksyetylenenheter The polyalkylene oxide adduct is obtained by reacting a fatty acid sorbitan monoester with ethylene oxide and/or propylene oxide. Typically, the adduct contains from 12 to 25 oxyethylene units
eller fra 6 til 12 oksypropylenenheter pr. molekyl. or from 6 to 12 oxypropylene units per molecule.
Valget av disse overflateaktive stoffer er avhengig av deres tilgjengelighet, pris og renhet. Vanligvis er de foretrukne midler sorbitanmonooleat og dets polyetylenoksydaddukt, som inneholder et gjennomsnitt på ca. 20 oksyetylenenheter pr. molekyl. The choice of these surfactants depends on their availability, price and purity. Generally, the preferred agents are sorbitan monooleate and its polyethylene oxide adduct, which contain an average of about 20 oxyethylene units per molecule.
Den tredje komponent i blandingen av overflateaktive mid- The third component in the mixture of surfactants
ler er et alkalisalt av et dialkylsulfosuccinat, nærmere bestemt natriumsaltet av di(2-etylheksyl)sulfosuccinat, som vanligvis er kommersielt tilgjengelig! i form av en 75 prosentig vannløsning. clay is an alkali salt of a dialkylsulfosuccinate, specifically the sodium salt of di(2-ethylhexyl)sulfosuccinate, which is usually commercially available! in the form of a 75 percent water solution.
Blandingen av disse overflateaktive stoffer har en HLB som varierer fra ca. 9 til ca. 10,5, særlig fra ca. 9,4 til ca. 10,5. The mixture of these surfactants has an HLB that varies from approx. 9 to approx. 10.5, especially from approx. 9.4 to approx. 10.5.
Løsningsmidlet for blandingen av overflateaktive stoffer The solvent for the mixture of surfactants
er en blanding av vann og en monoalkylglykoleter hvor alkylgruppen inneholder 1-4 karbonatomer. Egnete glykoletre omfatter etylenglykolmonobutyleter, dietylenglykolmonobutyleter, dietylenglykolmonometyleter, dipropylenglykolmonometyleter og liknende. is a mixture of water and a monoalkyl glycol ether where the alkyl group contains 1-4 carbon atoms. Suitable glycol ethers include ethylene glycol monobutyl ether, diethylene glycol monobutyl ether, diethylene glycol monomethyl ether, dipropylene glycol monomethyl ether and the like.
Det har vist seg at dispergeringsmiddelsmaterialer som inneholder 65-75 vekt% av en blanding av de ovennevnte overflateaktive stoffer, mens resten av materialet utgjøres av løsnings-middelsblandingen, har særlig fordelaktige egenskaper når blandingen (som tørr blanding) inneholder 3 5-4 0 vekt% tørt succinat, og materialet inneholder minst 20% vann, regnet av materialets totale vekt. Den totale vannmengde i materialet bør ikke over-stige ca. 27,5%. It has been found that dispersing agent materials containing 65-75% by weight of a mixture of the above-mentioned surfactants, while the rest of the material is made up of the solvent-agent mixture, have particularly advantageous properties when the mixture (as a dry mixture) contains 35-40% by weight % dry succinate, and the material contains at least 20% water, calculated from the total weight of the material. The total amount of water in the material should not exceed approx. 27.5%.
Når det anvendes et hydrokarbonløsningsmiddel istedenfor den vannholdige løsningsmiddelsblanding eller tilsettes til det vannholdige løsningsmiddel, blir de resulterende materialer vanligvis uklare og oppviser lavere oljedispergerende effekt. When a hydrocarbon solvent is used instead of the aqueous solvent mixture or added to the aqueous solvent, the resulting materials usually become cloudy and exhibit lower oil dispersing effect.
Materialet ifølge den foreliggende oppfinnelse kan også inneholde et antall valgfrie bestanddeler, såsom næringsstoffer, korrosjonshindrende stoffer og andre vanlige tilsetningsstoffer. F.eks. kan det være fordelaktig å tilsette et flytepunktsenkende middel, såsom dietylenglykol, i en mengde som vanligvis ikke overstiger 5% av materialets totale vekt. The material according to the present invention can also contain a number of optional components, such as nutrients, corrosion-preventing substances and other common additives. E.g. it may be advantageous to add a pour point depressant, such as diethylene glycol, in an amount which usually does not exceed 5% of the total weight of the material.
Dispergeringsmaterialets effektivitet er bestemt ved anvendelse av testmetoden ifølge Warren Spring Laboratory (Depart-ment of Trade and Industry, Stevenage, Herfordshire). Ved denne test tilsettes materialet dråpevis til en oppmålt mengde olje som flyter på overflaten av en søyle av sjøvann anbrakt i en skilletrakt. Deretter rystes trakten for å dispergere oljen. The effectiveness of the dispersing material is determined using the test method according to the Warren Spring Laboratory (Department of Trade and Industry, Stevenage, Herfordshire). In this test, the material is added drop by drop to a measured amount of oil that floats on the surface of a column of seawater placed in a separatory funnel. The funnel is then shaken to disperse the oil.
Den oljemengde som er blitt dispergert i vannsøylen bestemmes etter at vannsøylen har fått stått stille i et tidsrom. Et mate-riales effektivitet uttrykkes som den prosent av oljen som er dispergert i vannfasen. The amount of oil that has been dispersed in the water column is determined after the water column has been allowed to stand still for a period of time. A material's efficiency is expressed as the percentage of the oil that is dispersed in the water phase.
