Definitions

  • the present invention relates to a method for removal of a pollutant floating on a body of water, in particular petroleum and/or its derivatives.
  • the present invention regards a method of removal that envisages the use of absorbent material.
  • the object of the present invention is to provide a method of the type referred to above that will be more efficient and economically advantageous than those of the known art.
  • FIG. 1 illustrates a atercraft for implementing the method described herein
  • FIG. 2 illustrates a schematic perspective view of the inside .of the watercraft of Figure 1 ;
  • Figure 3 illustrates a side view of the watercraft of Figure 1;
  • Figure 4 illustrates a top plan view of the watercraft of Figure 1;
  • - Figure 5 is a diagram of a system for implementing the method described herein; and - Figure 6 is an axonometric view of a system for providing the method described herein.
  • the method described herein has the purpose of removing a pollutant, in particular a floating liquid hydrocarbon substance, for example petroleum and/or its derivatives, from a body of water.
  • a pollutant in particular a floating liquid hydrocarbon substance, for example petroleum and/or its derivatives
  • the method described herein envisages the use of absorbent material.
  • the method described herein is characterized in that the absorbent material used is greasy animal wool, with large fibres, preferably sheep's wool.
  • the wool used in the method described herein has fibres of a diameter greater than or equal to 25 ⁇ , preferably between 25 and 40 ⁇ .
  • greasy wool is meant wool straight off the animal that has not yet been subjected to any washing treatment.
  • the present applicant has found, through an intense experimental activity, that the type of wool in question has a capacity of absorption of hydrocarbon substances, specifically liquid hydrocarbon substances, that is decidedly higher than the majority of absorbent materials used in the known art. Said higher absorption capacity would seem to be attributable at least in part to the diameter of the fibres of the wool used. Moreover, it has been found experimentally that wool of the type indicated can be re-used many more times than is instead allowed with the materials commonly used in this type of applications (which for the most part are plastic-resin or glass synthetic materials), enabling as a whole up to ten times the amounts that can be absorbed by said conventional materials.
  • said type of wool is able to absorb selectively only the hydrocarbon substances and not also the water on which these float, as instead occurs with conventional absorbent materials.
  • the present applicant has found that said property is typical of greasy wool, which, since it has not been in fact subjected to any washing treatment, is coated with a layer of grease that renders it water-repellent. It is thus evident that said type of wool guarantees, in the field of the applications in question, results that are decidedly better than conventional absorbent materials, above all in terms of efficiency of absorption, not only because it has a greater capacity for absorbing hydrocarbon substances, but also because it is able, given that it does not absorb water, as instead said conventional materials do, to exploit its capacity fully.
  • the layer of grease and of equivalent substances is present in a weight percentage of between 15 wt% and 60 wt% .
  • any possible dispersion in the environment of the wool does not create ecological problems in so far as it is a product of natural and biodegradable origin;
  • the wool impregnated with the hydrocarbon substance absorbed can be used as combustible material, for example within incinerator systems;
  • the method described herein can envisage different specific embodiments.
  • said method envisages dipping the wool in the hydrocarbon substance and then taking it out after it has been impregnated with said substance.
  • Preferred embodiments can envisage that the impregnated wool is squeezed in order to separate and collect in a tank the hydrocarbon substance that has been absorbed, and, subsequently, that the squeezed wool is re-used for removing further amounts of said substance .
  • the first system illustrated in Figures 1 to 4
  • the second system illustrated in Figures 5 and 6
  • the second system has been specifically devised for interventions in confined bodies of water, such as ports, canals, or lakes, or in any case for interventions in which the amounts of pollutant to be removed are decidedly smaller.
  • the watercraft described herein is equipped with a system that enables operation during advance of the watercraft itself.
  • said system is prearranged for generating, exploiting precisely the motion of advance of the watercraft, a continuous flow of absorbent material in bulk form, which from the watercraft is let down into the sea, directly on the patch of pollutant, and is then brought back again onto the watercraft.
  • the -system has:
  • - a frame designed to delimit laterally a strip of body of water that extends along at least one of the sides of the watercraft;
  • a conveying surface for bringing back onto the watercraft the absorbent material previously let down, said surface having a portion immersed in said strip of water, which occupies a position that, with respect to where the absorbent material is let down, is set at a distance in the direction opposite to that of advance of said watercraft, said portion being designed to intercept the absorbent material lowered into said strip; as will be seen in what follows, the elements referred to above, which make up the system, are all mounted on the watercraft and are carried by the latter .
  • Illustrated in Figure 1 is an example of watercraft on which the system in question is to be installed. It is clear that the watercraft can in ' any case be also of any other type; for example, it can also be a simple floating structure without means of propulsion of its own, which must then be towed by another watercraft.
  • the aforesaid frame comprises a guard 4, which extends along one side of the watercraft and at a given distance therefrom, is- anchored to the watercraft, by means of purposely provided lattices 6 arranged on the deck of the watercraft, and is rendered floating by means of buoys 5 anchored to it.
  • the lattices engage the guard 4 so as to enable this to move vertically with respect to the lattices, in order to remain on the surface of water, in one and the same condition partially immersed, whatever the plane of floating of the watercraft.
  • the guard constitutes a divisory element of the free surface - or of a slightly deeper portion - of the body of water, which delimits, together with the side of the watercraft facing it, a channel 8 (which is obviously limited laterally but not on the bottom) .
  • the guard extends substantially from bow to stern.
  • said channel prevents the absorbent material from dispersing and, at the same time, conveys it, as a result of the headway of the watercraft, towards the conveying surface referred to above, designated by the reference number 12 in the figures.
  • the aforesaid means (designated by the reference number 16 in the figures) for lowering the absorbent material, i.e., the tufts of wool, in the sea, into the channel 8, are set on the watercraft so as to be able to let down said material at the end of said channel closest at the bow of the watercraft, whilst the conveying surface 12 is set so as to be immersed in said channel substantially at the end of this closest to the stern.
  • the aforesaid means envisage an alternating movement that enables distribution of the tufts of wool substantially throughout the width of the channel 8.
  • said means are formed by a set of chutes and/or conveyor belts 16, the last of which terminates beyond the side of the watercraft for casting said material into the channel 8.
  • a storage area designated by the reference number 18, where containers containing the greasy wool to be used in the system are arranged.
  • tufting units 17 designed to break the wool taken from the container up into tufts.
  • the conveying surface 12 is an inclined conveying surface, which is anchored to the watercraft, and which from the level of the deck of the watercraft reaches the surface of the sea until it is immersed, at least partially, in the channel 8, in the proximity of the end of the latter closest to the stern.
  • the surface 12 is formed by a mesh conveyor belt, driven by appropriate means (not illustrated) , which is made to advance in the direction of ascent of the surface defined thereby. Said belt has the function of intercepting the absorbent material present in the channel and of bringing it back on to the deck of the watercraft. It will be appreciated that the mesh structure of the belt enables interception and collection of the absorbent material, reducing to a minimum the resistance exerted by the water, against the belt as a result of advance of the watercraft.
  • a further conveyor belt designated by the reference number 22, which is designed to bring the material gathered as far as an opening 26 where a set of squeezing rolls 24 is located, designed to squeeze the absorbent material for separating from this the pollutant, which ends up in the tank 19 inside the hull of the watercraft.
  • two conveyor belts 15 and 27 are provided, designed to bring the absorbent material that has been squeezed back again to the lowering means 16.
  • a freely rotating set of rolls 25 is provided within the channel, which are carried by the same frame as the one that carries the guard, and are kept in a position raised with respect to the hull of the watercraft so as to remain immersed in the water and to be set in rotation as a result of the advance of the watercraft.
  • the rolls 25 can also be motor-driven so as to render their movement of rotation independent of the speed of advance of the watercraft. Said rolls have the function of agitating and mixing the absorbent material contained in the channel 8.
  • the same configuration described above can be provided in a symmetrical way on both sides of the watercraft.
  • the portion of surface of water that is involved in the process of depuration is substantially the same as the one comprised in the encumbrance defined between the guard and the central part of the bottom of the hull of the watercraft; this means that in the case illustrated, where the system envisages the same configuration on both sides of the watercraft, the width of the total surface of water involved is equal to the one comprised in the encumbrance between the two guards arranged on the opposite sides of the watercraft .
  • this envisages, as first step, lowering of the absorbent material in bulk form into the channel, after tufting thereof has been carried out by the tufting units 17.
  • said material traverses the entire channel until it is brought up to the conveying surface, and whilst said material is in the channel, the action of the rotating rolls causes it to be impregnated completely by the pollutant.
  • this gathers it and delivers it onto the conveyor belt 22, which carries it up to the rolls 24, where it is squeezed and separated from the pollutant, which is collected in the tank 19 whilst said absorbent material is brought back via the belt 27 to the lowering means 16.
  • Alternative embodiments can in any case envisage discharge of the absorbent material gathered by the channel 8 directly into the tank 19, and hence not envisage the aforesaid closed cycle so that in said embodiments the means referred to above, such as the squeezing rolls 24, the conveyor belts 15 and 27, etc., designed for providing said closed cycle, may thus be omitted.
  • the system described ⁇ herein preferably envisages means for controlling the operation described above in an automatic or semi-automatic way.
  • said means have the function of controlling the speed of the watercraft and the rate of flow of material that is cast into the channel in a coordinated way, according to the required operating conditions.
  • Said means can envisage an interface, via which it is possible to select or set the various combinations. For instance, in the case of thick patches of pollutant it will be necessary to set low cruising speeds and provide large amounts of absorbent material .

  • the exhausted wool i.e., after 10 cycles of use
  • the exhausted wool possesses a calorific power of 27.8 MJ/kg, namely, more than 2000 times the calorific power of normal waste, and almost twice that of dry wood.
