Definitions

  • the invention relates to oil-sorbent compositions, and to methods of clearing oil-spillages on land or on water using such compositions.
  • One very suitable and versatile absorbent material is a by-product of sphagnum moss which is sold by essex Resource Ltd of Dorset, UK, under the Trade Mark OILSORB. It is a hydrophobic and oleophilic non-toxic biodegradable organic fibre obtainable from self-regenerating peatlands. It does, however, have certain disadvantages in its use. One is that it is very dusty. It could not, for example, realistically be used to treat a widespread oil-spillage on water as the dust problem in spreading a large quantity of the moss over a large area would be too great . The material is very light, which makes it difficult to spread in the open if there is any wind.
  • WO-A-9526228 discloses an oil-sorbent composition which comprises, in specified proportions, a particulate sorbent substrate, a fire retardant, a hydrophobic additive, and an effective amount of an oil-digesting micro-organism. Preferably the micro-organism is isolated from the other three components of the mixture by being encapsulated in an oleophobic compound.
  • WO-A-9526228 also discloses a method of use for the above composition, which is used loose, or contained in pads, socks, pillows or booms. The composition, preferably in its contained form, is spread at the site of an oil-spillage and absorbs the spilt oil until saturated.
  • It may then be either removed to a disposal site such as a landfill site with the encapsulated microbes still in their dormant state, protected by the oleophobic and hydrophilic protective nutrient coating; or it may be compressed to squeeze out and recover up to 70% of the sorbed oil, prior to re-use.
  • a disposal site such as a landfill site with the encapsulated microbes still in their dormant state, protected by the oleophobic and hydrophilic protective nutrient coating; or it may be compressed to squeeze out and recover up to 70% of the sorbed oil, prior to re-use.
  • the saturated matting is deposited at a landfill site and exposed to the elements, then in time the encapsulation of the microbes will break down, and the oil-digesting micro-organism will commence digestion of the oil.
  • a major disadvantage of the matting of WO-A-9526228 is that it must be physically removed from an oil-spill site when saturated with oil, for compression to squeeze out the sorbed oil or for activation of the bio-mass by destruction of the encapsulating protective layer around the micro-organisms. Any handling of the oil-saturated matting is messy and expensive, and involves a risk of spreading the boundaries of the oil-spill area.
  • the invention provides an oil-sorbent composition
  • an oil-sorbent composition comprising the following components in admixture:
  • the inventors have created an effective oil-sorbent composition which may be used in a unique manner quite distinct from the manner of use described in WO-A-9526228.
  • matting incorporating the composition of the invention can be left in place at an oil-spill site where it will simultaneously absorb and digest the spilt oil. That is made possible by the provision, in the composition, of both the water-soluble polymer and the hydrophobic sorbent solid for sorbing the oil.
  • the former absorbs water, which creates a supply of nutrient medium for the micro-organism and maintains an ideal growth environment for the micro-organism as it digests in situ the oil sorbed by the hydrophobic solid.
  • the water absorption of the water-soluble polymer does not detract from the oil-sorbency of the hydrophobic solid, even when matting containing a composition according to the invention is laid at a potential oil-spillage site and then immediately hosed down with water to activate the micro-organisms and generate a substantial water retention within the composition prior to its being exposed to a later oil-spillage.
  • the effective amount of the oil-digesting micro-organism is preferably at least 0.001% by weight of the composition. There is no absolute higher limit, but above 15% by weight is unlikely to be cost-effective. Concentrations of micro-organisms in the composition of from 0.001% to 15% by weight are therefore preferred.
  • the oil-digesting micro-organism may be any known micro-organism. Examples include
  • Enterobactor sakazakii (strain 1) Enterobactor sakazakii (strain 2) Klebsiella s . Arthrobacter sp . (strain 1) Arthrobacter s . (strain 2) Pseudomonas sp. Acinotobacter
  • micro-organisms may also be used.
  • the micro-organism are used in the form of dried bacterial cultures (DBCs) .
  • DBCs dried bacterial cultures
  • the cultures are conveniently obtained supported on bran carriers.
  • the nutrient for the micro-organism may be inorganic or organic.
  • Organic nutrients that are suitable include dried animal litter and composted vegetative waste.
  • Inorganic nutrients would typically contain as main constituent elements nitrogen, phosphorus (in the form of phosphates) and potassium and could be presented in a powder or granular form.
  • the water-soluble polymer acts as a wetting agent for wetting the micro-organism and nutrient when the composition of the invention comes into contact with water.
  • the micro-organism and nutrient are dispersed through the composition in intimate and uniform contact with both the hydrophobic sorbent solid and the water-soluble polymer.
  • Water-soluble polymers which have been used successfully include modified celluloses such as methyl cellulose, hydroxypropyl methyl cellulose and methyl ethyl cellulose. Non-cellulosic water-soluble polymers may however also be used.
  • composition of the invention is presented and used is in the form of a mat or boom which can be floated on the surface of water which has been contaminated by an oil-spillage.
  • the composition comprising the hydrophobic sorbent solid, the oil-digesting micro-organism, the nutrient and the water-soluble polymer is contained within a fabric outer covering of the mat or boom, and the mat or boom can then be floated or spread on the surface of an area of water contaminated by an oil-spillage.
  • the oil passes through the fabric outer covering of the mat or boom and is sorbed by the composition of the invention.
  • the water-soluble polymer is wetted by water which also passes through the fabric outer covering of the mat or boom, and creates an aqueous medium for the micro-organism to cultivate and grow.
  • the micro-organism feeds on the sorbed oil, breaking it down and effectively dispersing it.
  • a hydrophobic carrier for the oil namely the hydrophobic sorbent solid such as dried sphagnum moss
  • the hydrophilic polymer which acts as a carrier for the micro-organism creates a symbiotic combination which results in an extremely rapid and complete degradation of the oil.
  • the invention is not, however, limited to the treatment of oil-spillages on water.
  • a very significant application is the treatment of oil-spillages and oil contamination on dry land or the protection of areas where oil contamination is likely.
  • the composition of the invention can be used, for example, to protect rail-track beds, or to protect or clean up industrial premises where oil contamination is likely such as transformer yards; around heavy duty electrical switchgear; in lorry or bus depots and in refuelling bays.
  • the composition of the invention may be presented in the form of a mat filled with the composition, although generally speaking less robust matting will be appropriate on dry land than for treating oil-spillages on water. After spreading the matting it may be hosed down with water which is taken up by the hydrophilic polymer and provides a culture medium for the micro-organisn which then over time effectively digests the sorbed oil.
  • composition of the invention For some dry land applications it will probably be appropriate simply to spread the composition of the invention over the contaminated area without the use of any matting or other containment structure.
  • the layer of treatment composition is then wetted with water to activate the micro-organism.
  • the composition can then be left in situ or swept up and disposed of in an ecologically acceptable manner.
  • the disposal of the composition of the invention after oil sorption is ecologically acceptable.
  • the oil is degraded or digested by the micro-organism, and the composition after oil treatment can be used as a most valuable fertilizer or soil improver. Alternatively some or all can be re-used by the incorporation of more micro-organism and/or more nutrient medium and/or more water-soluble polymer to create more oil-sorbent composition according to the invention.
  • the composition may incorporate a fire retardant for the hydrophobic sorbent material, and may further incorporate pellets of fired clay.
  • the hydrophobic sorbent material is thus dispersed amongst discrete particles of porous and non-inflammable material, provided by the fired clay pellets.
  • a mat containing such a composition is ideally of a layered construction, with a non-inflammable outer layer of fired clay pellets over a bottom or core layer of the composition of the invention.
  • Figure 1 is a vertical cross-section through a mat according to the invention.
  • Figure 2 is a vertical longitudinal section through the mat of Figure 1.
  • a mat 1 for use in the lining of rail-track beds.
  • the mat may be of indeterminate length, as illustrated by the discontinuity A in its longitudinal section.
  • the mat covering is a stout woven fabric 2,3 of polypropylene or similar strong and non-biodegradable material . The same material is used for an intermediate fabric layer 4.
  • first containment chamber 5 Between the bottom fabric 2 of the mat and the intermediate fabric layer 4 is formed a first containment chamber 5, and between the intermediate layer 4 and the top fabric layer 3 of the mat are formed a series of parallel containment chambers 6.
  • the width W of the mat is slightly less than the rail width of a rail track.
  • the containment chamber 5 is loosely filled with a composition 7 of the invention, and each of the containment chambers 6 is loosely filled with pellets of fired clay 8.
  • the fired clay provides a good oil- and water-absorbent layer which is naturally fire-resistant and fire-retardant .
  • composition 7 comprises, by weight, the following ingredients in intimate admixture one with another.
  • SILVAPERL HYDROXELA fired clay pellets were used because they were commercially available, any expanded clay aggregate would serve the same purpose .
  • SILVAPERL HYDROXELA TM fired clay pellets 36.4% by weight hydroxymethyl cellulose ether (HMCE)
  • the preferred sequence of mixing the composition is as follows: first of all the "Oilsorb” and clay pellets are dry mixed together in a mixer. Then the fire retardant is added, in batches, while maintaining the mixing.
  • the fire retardant which is an aqueous liquid, is initially absorbed by the clay pellets which have the higher absorbency and are very hydrophilic. As mixing continues, however, the fire retardant is drawn from the clay pellets by the "Oilsorb” product, and coats the dried moss without the creation of a slurry ball of moss such as would be created if the aqueous fire retardant were added to the moss alone.
  • methyl cellulose absorbs the water from the damp moss and clay, and forms gel beads adhering to strands of the moss and to beads of the clay.
  • the mixing temperature is raised to dry the gel.
  • the DBC and nutrient media are added to the mixture and thoroughly dispersed through the dry mixture .
  • the filled mats 1 are structurally quite stable and are easy to handle either individually or stacked on pallets . In use they are spread out in a single thickness row between rail tracks, with the fired clay pellet layer 8 on top. The mats 1 are then thoroughly hosed down with water, which is absorbed by the clay pellets 8 and retained by the HCME which again reverts to gel form.
  • the micro-bacteria are activated by the presence of water, and start to grow and to multiply in the presence of the nutrient medium. As they grow, they digest any oil which is on the tracks below the matting together with any new oil which drips onto the matting from above. In a situation such as a railway station, where the oil leakage between the rails is fairly constant, the regeneration of the mat is largely self-sustaining.
  • the HCME hydrophilic polymer retains enough water to maintain an aqueous environment for growth of the culture, and the regular oil contamination is a sufficient food supply for that growth.
  • the micro-organism culture may start to digest the HCME itself, but that is available in such a sufficient supply that there is no overall degradation in the efficiency of the oil-sorbing and oil-digesting properties of the mat. All that is necessary to maintain the mat viable is to re-wet the mat regularly by a liberal soaking.
  • the mat may be left in position for prolonged periods possibly for some years, before a surface accumulation of oil shows that the biological activity has been lost. At that stage the entire matting or an individual mat (as appropriate) can be lifted and replaced, and its composition 7 re-used in the creation of new matting.
