Description

461 285" " 10 15 20 25 30 35 2 av det slag som marknadsförs under benämningen ABSOL. 461 285 "" 10 15 20 25 30 35 2 of the kind marketed under the name ABSOL.

Dylik lättbetong uppvisar såväl makroporös som mikro- porös struktur vilken ombesörjer en effektiv uppsugning av olja förutsatt att denna befinner sig i flytande tillstànd. Lättbetongen låter sig enkelt krossas och finfördelas i önskade kornstorleksfraktioner alltifrån mycket fina partiklar till korn av storleken 1-5 mm.Such aerated concrete has both macroporous and micro- porous structure which ensures an efficient absorption of oil provided that it is in liquid condition. The lightweight concrete can be easily crushed and comminuted in desired grain size fractions from very fine particles to grains of size 1-5 mm.

För det aktuella ändamålet kan med fördel användas en blandning av finare beståndsdelar eller partiklar (0,00l-1,0 mm) och kornformiga beståndsdelar (1-5 mm).For the current purpose can be used to advantage a mixture of finer constituents or particles (0.00l-1.0 mm) and granular constituents (1-5 mm).

Lämpligast blandas det beskrivna oljeuppsugnings- medlet med den pulverformiga, brända kalken och påförs den förorenande oljan genom flygbesprutning, varvid blandningen företrädesvis genomförs omedelbart före saneringsoperationen. Kalken och lättbetongmaterialet kan förvaras i separata behållare och blâsas eller matas in i en gemensam tank, exempelvis till en helikop- ter, varvid kalken (CaO) vid kontakt med det vatten som i varierande mängder städse förekommer i lättbetongen i såväl fri som bunden form reagerar med vattnet under värmeutveckling. När därefter blandningen påförs oljan, exempelvis utmed ett strandavsnitt, uppvärms oljan av blandningen till temperaturer inom omrâdet 50-90° C, varvid oljan övergår i ett flytande tillstånd i vilket densamma sugs upp i lättbetongmaterialets porer under bildande av torra klumpar som är enkla att avlägsna och som till och med kan tillåtas kvarbli på sanerings- omràdet emedan oljans miljöskadliga verkan neutraliseras så snart oljan uppsugits i lättbetongkornen.Most preferably, the described oil suction the agent with the powdered, calcined lime and applied the polluting oil by aerial spraying, whereby the mixing is preferably carried out immediately before the remediation operation. The lime and lightweight concrete material can be stored in separate containers and blown or fed into a common tank, for example to a helicopter wherein the lime (CaO) on contact with the water which in varying amounts always occurs in the aerated concrete in both free and bound form reacts with the water below heat generation. When then the mixture is applied to the oil, for example, along a beach section, the oil is heated of the mixture to temperatures in the range of 50-90 ° C, the oil turning into a liquid state in which the same is absorbed into the pores of the aerated concrete material forming dry lumps that are easy to remove and which may even be allowed to remain on the the area because the environmentally harmful effect of the oil is neutralized as soon as the oil is absorbed into the aerated concrete grains.

Den vanliga brända kalken (CaO) utvecklar värme tämligen snabbt vid kontakt med vatten. Därest denna värmeutvecklíng skulle tendera att bli alltför häftig kan enligt uppfinningen kalken blandas med varierande mängder dolomitkalk (Ca0Mg0) vid vilken värmeutveck~ lingen sker långsammare. Genom att reglera proportio- nerna mellan CaO och CaOMg0 kan värmeutvecklingen regleras så att blandningen erhåller önskad temperatur 10 15 20 461 283 vid saneringstillfället.The common burnt lime (CaO) develops heat fairly quickly on contact with water. Then this heat generation would tend to be too violent according to the invention, the lime can be mixed with varying amounts of dolomite lime (Ca0Mg0) at which heat evolution ~ is slower. By regulating the proportion between CaO and CaOMg0 can heat development is regulated so that the mixture reaches the desired temperature 10 15 20 461 283 at the time of decontamination.

Lättbetongen eller oljeuppsugningsmedlet blandas' med kalken i volymproportioner inom området 0,3:l till l:0,3, företrädesvis i proportionen 1:1.The aerated concrete or oil absorber is mixed ' with the lime in volume proportions in the range 0.3: l to 1: 0.3, preferably in the ratio 1: 1.

Ehuru det föredras att blanda samman oljeuppsug- ningsmedlet och kalken redan före páföringen på oljan är det i och för sig tänkbart att pàföra medlet ifråga i separata steg, närmare bestämt på så sätt att kalken pàförs i ett första steg och oljeuppsugningsmedlet i ett påföljande steg. Detta utförande är särskilt tänkbart i det fall oljan befinner sig i kontakt med vatten, t ex genom att finnas i ett strandomràde eller vara underkastad verkan av nederbörd, varvid kalken reagerar med det pà oljan naturligt förekommande vattnet omedelbart innan oljeuppsugningsmedlet páförs.Although it is preferred to mix oil suction and the lime even before application to the oil is it per se conceivable to apply the agent in question in separate steps, more specifically in the manner of the lime applied in a first step and the oil absorber in a subsequent step. This design is special conceivable in the event that the oil is in contact with water, for example by being in a beach area or be subject to the action of precipitation, whereby the lime reacts with the water naturally occurring on the oil immediately before applying the oil absorber.

I det fall kalken och lättbetongmaterialet blandas med varandra före saneringen kan det vara lämpligt att före sammanblandningen befukta lättbetongmaterialet genom särskild vattenbegjutning, därest detta genom långt driven torkning skulle uppvisa extremt låg fukt- _halt.In that case the lime and lightweight concrete material are mixed with each other before decontamination may be appropriate to moisten the aerated concrete material before mixing by special water spray, whereby this by far-reaching drying would exhibit extremely low humidity _slippery.
