Definitions
- This invention relates to synergistic biocidal or metal sulphide dissolving compositions.
- the present invention is a selection invention relative to our published P.C.T. application WO 99/33345.
- the said WO 99/33345 discloses synergistic biocidal compositions comprising “THP”, a non-surfactant biopenetrant compatible with “THP” and optionally a surfactant.
- TPP is defined in WO 99/33345 as meaning either a tetrakis(hydroxyalkyl)phosphonium salt or a tris(hydroxyalkyl)phosphine. To avoid confusion we shall hereinafter refer to “THP salts” or “THP” respectively.
- non-surfactant biopenetrants disclosed in the said WO 99/33345 include phosphonated derivatives of carboxylic acids, for example the phosphonated telomers disclosed in our published European applications EP-A-0 491 391 and EP-A-0 861 846.
- non-surfactant biopenetrants disclosed in the said WO 99/33345 include a copolymer of N,N,N′,N′-tetramethyl-1,2-diaminoethane with bis(2-chloroethyl)ether. This is commercially available under the trade name WSCP and will hereinafter be so referred to.
- examples disclosed in the said WO 99/33345 include sulphonated (anionic) surfactants and cationic surfactants such as those based on quaternary ammonium compounds, as well as non-ionic, amphoteric and semi-polar surfactants.
- the biopenetrant is a phosphonic acid-tipped polymer or copolymer, it acts synergistically with a THP salt to considerably enhance the biocidal efficacy of the THP salt against both planktonic (free-swimming) and sessile (attached) bacteria.
- biopenetrant is a phosphonic acid-tipped polymer or copolymer, it acts synergistically with a THP salt to enhance the efficacy of the THP salt in the dissolution of metal sulphide, especially iron sulphide, scale.
- the present invention provides a synergistic composition comprising:
- the synergistic composition may be a synergistic biocidal composition and/or a synergistic metal sulphide (e.g. iron sulphide) dissolving composition.
- a synergistic metal sulphide e.g. iron sulphide
- the THP salt is tetrakis(hydroxymethyl)phosphonium sulphate (THPS).
- THP salts include the phosphite, bromide, fluoride, chloride, phosphate, carbonate, acetate, formate, citrate, borate, and silicate.
- the biopenetrant may comprise a polymer of an unsaturated carboxylic acid or a copolymer of an unsaturated carboxylic acid with a sulphonic acid, said polymer or copolymer being either terminated by vinylphosphonic acid (VPA) or vinylidene-1,1-diphosphonic acid (VDPA) or having such monomers incorporated into the polymer backbone; accordingly the biopenetrant may be a random copolymer incorporating VPA and/or VDPA monomers.
- VPA vinylphosphonic acid
- VDPA vinylidene-1,1-diphosphonic acid
- the polymer or copolymer of the biopenetrant may suitably be a polyacrylate or an acrylate/sulphonate copolymer.
- the biopenetrant may be a polyacrylate terminated with vinylphosphonic acid, (hereinafter “VPA end-capped polymer”) or with vinylidene-1,1-diphosphonic acid (hereinafter “VDPA end-capped polymer”), or may be a polyacrylate incorporating VPA and/or VDPA monomers.
- VPA end-capped polymer vinylphosphonic acid
- VDPA end-capped polymer vinylidene-1,1-diphosphonic acid
- the biopenetrant may be an acrylate/sulphonate copolymer terminated with vinylidene-1,1-diphosphonic acid (hereinafter “VDPA end-capped copolymer”) or with vinylphosphonic acid (hereinafter “VPA end-capped co-polymer”), or may be an acrylate/sulphonate copolymer incorporating VPA and/or VDPA monomers.
- VDPA end-capped copolymer vinylidene-1,1-diphosphonic acid
- VPA end-capped co-polymer vinylphosphonic acid
- the preferred ratio of VPA or VDPA end-capped polymer or copolymer to THP salt is, when expressed as a percentage by weight, in the range of from 0.5 to 50%, such as from 0.5 to 30%; preferably from 1 to 25%, such as from 1 to 20%, for example from 1 to 10% or from 2 to 8%; most preferably from 1 to 5%, for example from 3 to 5% (based upon active solids and upon a 1 to 74%, for example a 50%, active THP salt formulation).
- the biopenetrant is a VPA end-capped polymer or VDPA end-capped copolymer.
- VPA end-capped polymer or VDPA end-capped copolymer to THP salt is, when expressed as a percentage by weight, in the range of from 0.5 to 50%, such as from 0.5 to 30%; preferably from 1 to 25%, such as from 1 to 20%, for example from 1 to 10% or from 2 to 8%; most preferably from 1 to 5%, for example from 3 to 5% (based upon active solids and upon a 1 to 74%, for example a 50%, active THP salt formulation).
- composition may, in one embodiment, be provided in the form of a solution, for example an aqueous solution.
- composition may be supplied as a solid, for example a solid formed by coating the components onto, or absorbing the components into, a powdery granular or porous acid substrate such as adipic acid or by incorporation into a waxy substrate.
- compositions according to the present invention may be used as biocides against both planktonic (free-swimming) and sessile (attached) bacteria.
- compositions according to the present invention are equally effective in reducing the level of general heterotrophic bacteria and of sulphate reducing bacteria in waters.
- the invention therefore also provides a method of treating a water system contaminated, or liable to contamination, with microbes such as bacteria, fungi or algae, which method comprises adding to said system separately or together, a biocidally active amount of a THP salt and a biopenetrant, in which the biopenetrant comprises a polymer of an unsaturated carboxylic acid or a copolymer of an unsaturated carboxylic acid with a sulphonic acid, said polymer or copolymer being terminated by a mono- or di-phosphonated unsaturated carboxylic acid group or being a random copolymer containing a mono or di-phosphonated unsaturated carboxylic acid, thereby killing at least some of said microbes.
- the biopenetrant comprises a polymer of an unsaturated carboxylic acid or a copolymer of an unsaturated carboxylic acid with a sulphonic acid, said polymer or copolymer being terminated by a mono- or di-phosphonated uns
- the water system may, for instance, be contaminated with bacterial slime and/or planktonic bacteria.
- the invention may be of use for treating aerobic systems such as cooling towers, paper processing systems and waste water systems, and also for anaerobic systems, such as oil wells, e.g. during secondary recovery.
- the invention may also be suitable for use in the preservation of slurries and functional fluids, such as drilling muds, completion fluids, stimulation fluids and fracturing fluids.
- compositions according to the present invention may also be used to dissolve metal sulphides, preferably iron sulphide; in particular they may be used to dissolve iron sulphide scale.
- metal sulphide may be lead sulphide or zinc sulphide or a combination of iron or lead and zinc sulphides.
- the iron sulphide may typically be troilite (FeS) or pyrite (FeS 2 ), but any iron sulphide species can be dissolved using the invention.
- the invention therefore also provides a method of treating a water system containing or in contact with a metal sulphide scale, for example an iron sulphide scale, which method comprises adding to said system separately or together, a THP salt and a biopenetrant, in which the biopenetrant comprises a polymer of an unsaturated carboxylic acid or a copolymer of an unsaturated carboxylic acid with a sulphonic acid, said polymer or copolymer being terminated by a mono- or di-phosphonated unsaturated carboxylic acid group or being a random copolymer containing a mono or di-phosphonated unsaturated carboxylic acid, thereby dissolving at least part of said scale.
- a metal sulphide scale for example an iron sulphide scale
- the invention may be of use in the oil and gas industry, for treating systems such as oil wells, gas wells, pipelines, storage vessels and production equipment, e.g. during secondary recovery, and in other industrial water systems,. for instance in paper industry systems.
