Definitions
- the present invention relates to pumice stones, their production process and their applications.
- Pumice is a glassy, light-colored volcanic rock. It has quite exceptional characteristics in the form of closed internal cells and open external cells. It is very porous, hence its low density, its appearance is that of a sponge. Pumice is resistant to cold, fire, weather and is free from water-soluble salts. It is a silico-aluminate which contains particles (ash) of basalt, which can clog the pores.
- FR 2105752A describes a pumice stone having a particle size of 0.5 to 4 mm and a density of 350 kg / m 3 .
- DE 1941 199A proposes to absorb oil by pumice stone.
- the present invention relates to a new pumice stone.
- This new pumice stone has a carbon content of between 5 and 15% by weight, preferably between 10 and 13% by weight, and is characterized in that it has a particle size of between 3 and 8 mm and a density. less than or equal to 570 kg / m 3 and more than 500 kg / m 3 .
- the carbon content is determined by total combustion by the Dumas method by transformation of carbon into C0 2 and determination of C0 2 .
- This pumice stone containing carbon in the adsorbed state has the remarkable property of being able to absorb hydrocarbons, but of being hydrophobic. It is therefore particularly useful for cleaning up water plants polluted by oil.
- a pumice stone with a particle size of less than 6 mm and having an Si content is preferably chosen.
- a pumice stone of this kind having a carbon content according to the invention has a density less than or equal to 570 kg / m 3 .
- the pumice stone according to the invention has a density greater than 500.
- pumice stone having the Si0 2 and Al 2 0 3 contents mentioned above, we obtain the density indicated, which means that the pumice stone floats on the surface of the water. Its waterline is high. It is therefore most effective in adsorbing hydrocarbons that are spilled on the surface of the water body and it is easier to pick up after adsorption has taken place.
- a thickness of pumice stone between 1 and 4 cm and in particular 3 cm on the water, which gives an absorption yield of 30% of the volume of hydrocarbons. adsorbed in three minutes and 80% in half an hour.
- the pumice stone according to the invention is dispersed over the polluted body of water in any suitable manner, for example by hand, with a shovel, by a spraying device in the dry or wet process.
- Pumice having adsorbed oil can be picked up with the landing net, the recovery trawl, the hydraulic vacuum cleaner or in any other way.
- After picking up the pumice stone loaded with hydrocarbons it can be burned on the spot, or treated on the ground in harbor offices or in heating or steam generating devices for energy production. The regeneration by ignition of hydrocarbons takes place at 100%.
- the pumice stone according to the invention can be prepared very simply by adsorbing hydrocarbons with the pumice stone, then by igniting the pumice stone to burn the hydrocarbons, which leaves black smoke lining the pores and giving the carbon content. desired. It is preferable to first rid the pumice of fines, basalt, magnetite and volcanic ash which clog the pores. This can be done by washing with water with at least 20% by weight of water by spraying jets of water through a sieve on which the pumice is deposited. The jets lift the pumice grains, penetrate into the pores, rid them of the impurities which fall and pass through the sieve, which ensures the separation of the purified pumice.
- This pumice can then be dried in a dryer, for example in a dryer with a current of hot water, for example between 200 and 250 ° C. until the water content of the pumice is less than or equal to 10% by weight. .
- a current of hot water for example between 200 and 250 ° C.
- pumice having a moisture content of less than 2% by weight is commonly obtained.
- the adsorption of hydrocarbons to prepare the pumice stone according to the invention or to then use it for pollution control can be done at a rate of at least 20% by volume of adsorbed hydrocarbons until saturation.
- the invention finally relates to a method which consists in spreading a pumice stone according to the invention on the water, to leave it there between two minutes and eight hours and, preferably, between three minutes and two hours, then to pick up the pumice stone and ignite it to burn the hydrocarbons it contains.
- the following test illustrates the invention. 1) a plastic basin 0.5 m 2 in area has been filled with seawater (fifty liters). 2) a sample of treated pumice (containing 1 1, 60% of carbon by weight) was subjected to the flame to clearly show that the combustion was not taking place. 3) one liter of red domestic fuel oil was poured into the basin and then some three liters of treated pumice were dispersed on the surface of the basin so that the grains were in good contact with the fuel.
- the amount of organic compounds extractable in dichloromethane is between 180 mg and 220 mg per g of pumice, as determined by accelerated solvent extraction (ASE 200) carried out by liquid-solid extraction at high pressure (200 bars ) and high temperature (130 ° C).
- the diacids content is greater in the 1 mm thick surface layer than in the pumice core, as determined by analysis of the polar compounds sylilated by GC-MS as follows:
- High pressure extraction Extraction by accelerated solvent allows the organic extracts to be isolated from the solid matrix (insoluble organic matter and mineral phases). It is based on a liquid-solid extraction using solvents or combinations of solvents in order to extract, at high pressure and temperature, the extractable organic matter.
- the high pressures (up to 200 bar) keep the solvent in its liquid state.
- the dissolution of the extracts and the kinetic dissolution process are accelerated compared to the solvents used at lower temperature. This allows a reduction in the volumes of solvents used thanks to this increase in solvency capacities as well as a reduction in extraction working times.
- the apparatus includes a steel extraction cell connected to a heating system and electronically controlled pumps to maintain the selected temperature and pressure conditions.
- a silica filter is inserted at the base of the cell to prevent the passage of sample particles in the system. Glass beads are then introduced into the cell in order to allow better dispersion of the sample and thus obtain an optimum extraction yield.
- the "vacuum” cell is then extracted with the same solvent which will be used during the extraction (dichloromethane) in order to ensure the perfect cleanliness of the cells, the filter and the glass beads (rinsing). Table I presents the parameters used during the extractions.
- Table I Parameters for rinsing and extraction of the cells from the ase 200, (the "flusch” is the quantity of solvent used to rinse the cell (percentage of the volume of the cell)).
- the sample is weighed before being loaded into the cell.
- Each sample extraction takes place according to predefined parameters gathered in a method (Table I).
- a method specifies the duration of the heating of the cell, the temperature of the oven, the pressure maintained in the cell and the quantity of solvent necessary to rinse the cell (% flusch).
- the organic extract is reconcentrated using a Turbovap evaporator at a temperature of 35 ° C, then dried at room temperature, under a flow of argon, in order to avoid the oxidation of the compounds. 1.3.
- Each mineral phase (approximately 100 g) is rinsed thoroughly with cyclohexane and dichloromethane. These phases are then placed in an oven (120 ° C) overnight.
- the extracts diluted with dichloromethane are injected into the microcolumn containing activated alumina.
- the eluate consisting of a mixture of saturated hydrocarbons, aromatic hydrocarbons and part of the polar compounds is collected in a flask.
- the remainder of the polar compounds which remain trapped at the head of the column is eluted with a dichloromethane / methanol mixture (50/50, v / v).
- This first phase on an alumina column makes it possible to isolate a complex fraction of the polar compounds (macromolecules) which can disturb the second separation step on a silica column.
- the saturated and aromatic hydrocarbons as well as the polar compounds were analyzed by a Hewlett-Packard HP 5890 series II gas chromatograph coupled to a Hewlett-Packard 5972 mass spectrometer.
- the injector used is a spli-splitless continuously heated to 300 ° C.
- Chromatographic separation is carried out with a J&W Scientific DB-5 fused silica capillary column (length: 60m, diameter: 0.25mm; film thickness: 0.1 ⁇ m) with non-polar phase (5% phenylmethyl-siloxane ) depending on the temperature program: 60 ° C - 130 ° C at 15 ° C / min, 15 minute increments at 300 ° C.
- the carrier gas is helium, the flow rate of which remains constant at 1 ml / min throughout the duration of the analysis.
- the chromatograph is coupled to the mass spectrometer by a transfer line heated to 320 ° C.
