Definitions

  • the present invention relates to a pulp and paper manufacturing machinery cleaning composition according to claim 1.
  • the present invention further relates to a method for cleaning pulp and paper manufacturing machinery according to claim 11 and to the use of a pulp and paper manufacturing machinery cleaning composition according to claim 14.
  • Such industrial cleaning compositions are usually liquids that are supplied in drums or containers and will be applied by pumping or spraying onto the parts to be cleaned. As this procedure usually means that a process must be stopped to allow the cleaning operation to take place, the speed with which the cleaning effect takes place is of high importance.
  • the machine In for instance a plant intended to manufacture paper known as a paper machine, the machine is designed to separate fibres etc from aqueous slurry to form a web of wet paper on a continuous synthetic sieve, known as the "wire” or “formation wire” (as in the past it was made of woven bronze wire), whereby the wet paper web is then pressed between felts in the press-section to remove more water and then subsequently dried over heated cylinders in the drying-section.
  • a continuous, open weave fabric, known as the "drying wire” is usually used as a support as the drying paper web has limited strength.
  • the surfaces to be cleaned will take several forms.
  • there will be metal parts which due to the construction may be in the horizontal or up to the vertical plane or even the underside of a roof location such as the top inside a closed vessel such as the so-called "head-box" through which the paper slurry flows onto the formation wire.
  • a closed vessel such as the so-called "head-box”
  • it will almost certainly be necessary to clean the various open-weave sieves such as the formation wire where the paper components slurry is initially de-watered to form the wet paper web, or the drying-wire.
  • the felts in the press-section also present themselves as a porous substrate where unwanted contamination can de deposited.
  • cleaners for such machines can be in the form of for instance, aqueous solutions of alkali and tenside or acid and tenside.
  • the mixture may contain solvents whereby if the solvent is water soluble the mixture would be a solution but if the solvent were non-water soluble the mixture could be in the form of an oil-in-water emulsion.
  • the cleaner could even be a water-free solution of tenside in organic solvent.
  • the formation wires, the press-felts and the drying wires are open-weave or porous structures which allow water and thus low viscosity liquids to easily pass through.
  • any cleaning composition consisting of a typical oil-in-water emulsion is applied to such substrates, the greater proportion of such compositions will pass through the wire or felt whereby what remains would anyway be at least half water.
  • the active substances are evenly distributed throughout the water phase of the emulsion, only a limited part of the emulsified active components will make contact with the de-watering plant surfaces intended to be cleaned or remain adhered to such surfaces.
  • tensides that can maintain a hydrophobic solvent in a stable oil-in-water emulsified condition may also cause undesirable foaming effects.
  • quite large amounts of products known as defoamers are added specifically to reduce foam and the associated problems.
  • the object of the present invention is to overcome the disadvantages of the prior art.
  • the present invention is based on the finding that a minimum of active ingredients is needed if a maximum amount of cleaning composition may be deposited and held on the machinery components to be treated.
  • the present invention therefore relates to a pulp and paper manufacturing machinery cleaning composition which has a viscosity in the range of 100 to 3000 mPa ⁇ s measured at shear rates produced within the rotational speed range of 6 rpm up to 60 rpm at a temperature of 23°C.
  • the data refers to a measurement on a Brookfield LVT viscometer fitted with a Brookfield LV No. 2 Spindle and Brookfield LV Guardleg.
  • the cleaning composition of the present invention has a viscosity in the range of 300 to 3000 mPa ⁇ s, and most preferably of a viscosity in the range of 500 to 3000 mPa ⁇ s measured at shear rates produced within the rotational speed range of 6 rpm up to 60 rpm at a temperature of 23°C.
  • the data refers to a measurement on a Brookfield LVT viscometer fitted with a no. 2 spindle.
  • the pulp and paper manufacturing machinery cleaning composition has a viscosity in the range of 600 to 2500 mPa ⁇ s measured at shear rates produced within the rotational speed range of 6 rpm up to 60 rpm on a Brookfield LVT viscometer fitted with a no. 2 spindle and at a temperature of 23°C
  • Viscosity measurement is thereby done under the following conditions:
  • Newtonian viscosity characteristic means that the measured viscosity remains constant at different shear rates.
  • pseudo-plastic viscosity characteristic means the measured viscosity decreases at increasing shear rates.
  • thixotropic viscosity characteristic means that the measured viscosity decreases with the increase in length of time that the liquid is subjected to shear forces.
  • pulp and paper manufacturing machinery thereby means plant, machinery and parts thereof used for the manufacture of papermaking fibre such as mechanical pulp, chemical pulp, chemo-mechanical pulp, re-cycle pulp, paper, board and tissue.
  • plant parts especially include pulp-dewatering machinery and paper, board and tissue production machines including all parts and sections comprising such machines such as tanks, pipe-work, circuits, head-boxes, formation sections and their corresponding fabrics known as "wires", fibre-recovery plant such as poly-discs, press-sections and their corresponding felts, drying-sections and their corresponding fabrics, rolls and cylinders. Further examples include such plant as paper-coating machines.
  • the pulp and paper manufacturing machinery cleaning composition comprises two or more of the components selected from the group consisting of water, alkali, acid, tenside, chelating agent, organic solvent and/or thickener.
  • water may be added in the form of demineralised water, but also in mineralised form such as drinking or table water such as from a spring or surface water from rivers and lakes.
  • an alkali is a specific type of base, formed as a carbonate, hydroxide or other ionic salt of an alkali metal or alkali earth metal element.
  • Preferred are easily soluble, readily available alkalis such as sodium hydroxide, sodium carbonate, potassium hydroxide etc. whereby if low residual solids are required then ammonium hydroxide is suitable.
  • any substance may be used that, when dissolved in water, gives a solution with a pH of less than 7. It is preferred that the acid at the strength used is not detrimental to the surfaces to be cleaned whereby anti-corrosion additives such as but-2-yne-1,4-diol can be added.
  • Preferred acids and acidic substances are hydrochloric acid, sulphuric acid, phosphoric acid, nitric acid, sulphamic acid, glycolic acid, acetic acid, formic acid, aluminium chloride and citric acid.
  • tenside also known as surfactant or wetting agent
  • surfactant are organic compounds that are amphipathic, meaning they contain both hydrophobic groups, also known as tail groups, and hydrophilic groups, also known as head groups.
  • Tensides play an important role in many applications and products such as detergents, emulsifiers, adhesives, for wetting, foaming and defoaming.
  • a tenside or surfactant can be classified by the presence of formally charged groups in its head.
  • a non-ionic surfactant has no charge groups in its head. The head of an ionic surfactant carries a net charge.
  • the tenside or surfactant is called anionic, if the charge is positive, it is called cationic. If a surfactant contains a head with two oppositely charged groups, it is termed amphoteric.
  • Some commonly encountered tensides or surfactants of each type include tensides based on sulphate anions, sulphonate anions or carboxylate anions, such as fatty acid salts, sodium 2-ethylhexyl sulphate, sodium dodecyl sulphate, sodium lauryl sulphate, ammonium lauryl sulphate, dodecyl benzene sulphonic acid and other alkyl sulphate salts as anionic tensides or surfactants.
  • Cationic tensides or surfactants may be based on substituted ammonium derivatives such as quaternary ammonium cations. Examples are cetyl trimethylammonium bromide (CTAB) and other alkyltrimethylammonium salts. Further cationic tensides or surfactants are cetyl pyridinium chloride, polyethoxylated tallow amine (POEA), benzalkonium chloride. Examples for zwitterionic, i.e. amphoteric tensides or surfactants are dodecyl betaine, dodecyl dimethylamine oxide, cocamidopropyl betaine and coco ampho glycinate.
  • non-ionic tensides or surfactants examples include alkyl poly(ethylene oxide), alkyl polyglucosides, ethoxylated C9 - C16 aliphatic alcohols, poyoxyethylene stearylamine, fatty alcohols as well as cocamide MEA, cocamide DEA and cocamide TEA.
  • Preferred tensides are alkyl aryl sulphonate alcohol amine salt, polyethyleneglycol alkyl ether, alkyl sulphonsuccinate sodium salt and/or aliphatic alcohol ethoxylate.
  • chelating agent a compound is meant that binds avidly to form a complex with certain metals. Thereby, the ligands are coordinated to the metal ion.
  • EDTA ethylenediamine tetra acetic acid
  • Preferred chelating agents are EDTA, DTPA, Ethylenetriamine pentamethylene phosphonic acid Na-salt, polyacrylates, tetra potassium pyrophosphate, polyamines, polyphosphates and phosphonates.
  • organic solvent any organic solvent may be used that is not detrimental to the personnel, the machinery or the environment.
  • Preferred organic solvents or mixtures thereof are selected from the group consisting of saturated or unsaturated open-chain or cyclic, normal or isomeric hydrocarbon having 5 to 30 carbon atoms; acyclic, monocyclic and/or bicyclic terpene hydrocarbons or terpene alcohols, fatty acid esters, rape-seed oil methylester.
  • hydrocarbons obtainable from de-aromatized white spirit or hydrogen treated petroleum distillates, whereby the hydrocarbons have a boiling range such that the initial boiling point is typically between 175°C and 200°C and final boiling point of typically 220°C with a boiling range average of approximately 198°C.
  • derivatives of fatty acids are preferred organic solvents. Examples are fatty acid esters, rape-seed oil methylester or bio-diesel.
  • citrus oils are preferred organic solvents. Examples are orange terpene pressed from the rind of sweet oranges whereby a high proportion of the resulting solvent is limonene.
  • the combination of organic solvent and tenside comprises up to 20 wt% of citrus oils.
  • Thickeners are substances which, when added to a mixture, increase its viscosity without substantially modifying its other properties such as cleaning properties. Thickeners may be divided into the following groups:
  • the pulp and paper manufacturing machinery cleaning composition of the present invention is in the form of a solution, a suspension, a water-in-oil emulsion or a thixotropic liquid.
  • the pulp and paper manufacturing machinery cleaning composition according to the present invention may have a pseudo-plastic character meaning the viscosity reduces on being subjected to increasing shear and the pulp and paper manufacturing machinery cleaning composition may have a thixotropic character, i.e. it exhibits a progressively reduced viscosity the longer it is subjected to a given shear or when agitated.
  • the viscosity needed may be achieved in a variety of ways, depending on the components essential to the basic cleaning formulation.
  • a water-soluble thickener such as water soluble cellulose derivatives or xanthan gum may be added.
  • the tenside types used may be chosen to not only have a cleaning effect but also to create a stable water-in-oil emulsion of increased viscosity such as is achieved when oil and lemon juice is blended with egg yolk to give a mayonnaise with a much higher viscosity than the bulk of the starting ingredients.
  • Such a water-in-oil emulsion can possess a useful pseudo-plastic character that flows easily under shear stress but thickens when the shear is reduced or removed.
  • a mixture of solvent and tenside may be thickened with a hydrophobic colloidal silica powder.
  • Bentonite clays may be used to yield a pseudo-plastic and/or thixotropic properties of the pulp and paper manufacturing machinery cleaning composition.
  • Pseudo-plastic properties are highly desirable and yield excellent cleaning properties.
  • a pulp and paper manufacturing machinery composition having a viscosity in the range of 100 to 500 mPa s measure at the shear rate produced at the rotational speed range of 60 rpm at a temperature of 23 °C (Brookfield LVT viscosimeter fitted with a no. 2 spindle) and a viscosity in the range of 600 to 3000 mPa s measure at the shear rate produced at the rotational speed range of 6 rpm at a temperature of 23 °C (Brookfield LVT viscosimeter fitted with a no. 2 spindle)is preferred.
  • the ratio of the viscosities (viscosity (60 rpm)/viscosity(6 rpm)) measured at the above mentioned conditions should be within the range of 1:2 and 1:8, preferably 1:3 and 1:6 and most preferably 1:4 and 1:5.
  • the pulp and paper manufacturing machinery cleaning compositions according to the present invention have thixotropic properties.
  • the pulp and paper manufacturing machinery cleaning compositions according to the present invention has a viscosity in the range of 600 to 3000 MPa s measured after 5 seconds at the shear rate produced at the rotational speed range of 30 rpm on a Brookfield LVT viscosimeter fitted with a no. 2 spindle and at a temperature of 23 °C and a viscosity in the range of 100 to 500 mPa s measured after 180 seconds under the same conditions.
  • the ration of the viscosities measured under said conditions should be in the range of 1:1 to 1:10 and even more preferably in the range of 1:2 to 1:8.
  • the viscosity ratio (viscosity (180 seconds)/viscosity (5 seconds) is in the range of 1:3 to 1:5.
  • the present invention provides a method for making a pulp and paper manufacturing machinery cleaning composition for cleaning pulp and paper manufacturing machinery according to the present invention wherein the above mentioned components are mixed together.
  • the present invention relates to a method for cleaning pulp and paper manufacturing machinery whereby the above-identified pulp and paper manufacturing machinery cleaning composition is applied to the machinery or parts thereof.
  • Cleaning procedures may include the following:
  • the cross-flow manifold which distributes the flow of pulp slurry into the entry of the head-box is also often cleaned at a boil-out.
  • This pipe-work with a progressively decreasing diameter is difficult to clean and often overlooked but careful owners clean this with liquid cleaners or foaming cleaners followed by high-pressure water-jet rinsing.
  • the formation sieve or "wire” is often cleaned.
  • This wire is typically in the form of a continuous length of woven sieve running over a so-called “table” of supports and then returning over rollers which guide it and keep it in tension.
  • the "wire table” area is often situated in the horizontal plane.
  • the wire can become contaminated with deposits such as natural resins, synthetic polymers or so-called “stickies”, with filler such as carbonates and with scale etc.
  • a cleaning composition would be sprayed onto the weave of the wire and supports including the guide rolls whereby the wire would be slowly moving and the cleaning agents would be subsequently washed off.
  • the present cleaning formulations maximise the concentration of active components in contact with the surfaces to be cleaned and further maximise the contact time after initial application.
  • the pulp and paper manufacturing machinery cleaning composition is applied directly to the sieves, felts, fabrics, parts or units of the machinery being treated by a pressurized system using one or more nozzles to distribute the composition on the machinery.
  • the viscosity of the pulp and paper manufacturing machinery cleaning composition should remain at a level to enable pumping and spraying of the composition and moreover, that the composition still behaves as a liquid on the surface to be cleaned so as to enable fluid movement throughout the deposited layer of the pulp and paper manufacturing machinery cleaning composition.
  • the pulp and paper manufacturing machinery cleaning composition is applied directly to the sieves, felts, fabrics or parts or units of the machinery being treated by a gravity-fed system using mechanical means to distribute the composition on the machinery.
  • the pulp and paper manufacturing machinery cleaning composition is poured onto the horizontally slowly moving fabric and is evenly distributed by hand using a spreading device with a serrated edge made of a rubber material to avoid damage.
  • Example 1 Preparation of a water-based, alkaline pulp and paper manufacturing machinery cleaning composition with increased viscosity
  • the standard formulation was the same recipe but without the hydroxyethyl cellulose component.
  • the viscosity differences are seen in Figure 1 .
  • Example 2 Preparation of a water-based, acidic pulp and paper manufacturing machinery cleaning composition with increased viscosity
  • Ethoxylated C9-C 16 alcohols 0.5 Xanthan gum 0.5 Ethylenetriamine pentamethylene phosphonic acid, Na-salt 0.5 Fatty alcoholethylenglycol-polypropyleneglycolether 0.5 Polyoxyethylene-stearylamine 0.5 Hydrochloric acid 5 Water 92.5
  • Example 3 Preparation of a water-based, acidic pulp and paper manufacturing machinery cleaning composition with increased viscosity
  • the standard formulation was the same recipe but without the xanthan gum component.
  • the viscosity differences are seen in Figure 2 (together with a lower viscosity recipe from example 2).
  • Example 4 Preparation of a solvent/tenside-based, pulp and paper manufacturing machinery cleaning composition containing colloidal silica as thickening agent
  • the standard formulation was the same recipe but without the colloidal silica component.
  • Example 5 Preparation of an solvent/tenside containing pulp and paper manufacturing machinery cleaning composition in the form of a water-in-oil emulsion.
  • the standard product of this type was a neutral cleaner consisting of essentially solvent and tenside with traces of water and was a low viscosity liquid.
  • extra water is added whereby the tensides present cause the extra water added to form a water-in-oil emulsion which possesses a shear-thinning or pseudo-plastic character.
  • Wt.-% Mixture of n-, i- and cyclo-aliphatics, predominantly within range C11 - C12 70 Orange terpene, ex orange rind oil 10
  • Example 6 Application of a thickened cleaning agent as in example 1 to a paper machine formation wire
  • the formation wire of a paper machine was usually contaminated with patches of deposits including a high proportion of natural resins from the paper pulp. It was usual to use one of two similar commercial pulp and paper manufacturing machinery cleaning compositions, , both consisting of an aqueous solution of approximately 5% concentration of caustic soda together with certain tensides to restore the wire to a clean condition. From experience, the amount normally used of the first commercial cleaner was 200 litres of product sprayed onto the slowly moving formation wire in several portions to ensure that the wire remained as far as possible uniformly wetted out with the product for the duration of cleaning. It was also known from experience that a contact time of about 45 minutes was essential to achieve a clean wire.
  • the increased viscosity cleaner as in example 1 was dosed for 2 minutes through a spray-bar fitted with fan-nozzles to give an even coverage of the wire whereby a satisfactory coverage of the length of the formation wire and associated guide-rolls was achieved.
  • the cleaner was allowed to work for a further 10 minutes whereby the cleaner was again dosed for a further 2 minutes. After this time the cleaner was allowed to work for a further 16 minutes giving 30 minutes in total. After this time the cleaner was rinsed off with water for 10 minutes with the wire still travelling at 15 m/min. Thus the total time required for the cleaning and rinsing operation was 40 minutes.
  • the total amount of cleaner needed to give coverage of the wire for the 30 minutes duration using two short spray applications was 75 litres. This gave a use of 0.73 kg/m2 product compared to the total surface area of the wire.
  • Example 7 Application of a thickened cleaning agent as in example 2 to a vertical metal surface
  • Figure 7 shows the degree as to how far the two increased-viscosity compositions had run down the plate after 30 seconds and again after 5 minutes.
  • HVS-2 as in example 3 had run 7.5 cm and BR-S-0-5, HVS-1 as in example 2 had run 13 cm. After 5 minutes the cleaner HVS-2 had run 11.5 cm and HVS-1 had run 21 cm.
  • test plate was digitally photographed, the images scaled to true size, printed out onto plastic foil, the image area on the foil carefully cut out and weighed. Knowing the weight per unit area of the plastic foil, the area of the treated plate was calculated from the weight of the foil cut-outs.
  • Table 1 Specific coverage of a standard plus 2 increased viscosity pulp and paper manufacturing machinery cleaning compositions. 1 g applied to a vertical metal plate Standard HVS-1 HVS-2 Weight of composition remaining on plate (g) 0.08 1.02 1.02 Weight remaining on plate as percentage (%) 8 100 100 Area covered (treated) (cm2) 20.3 13.7 8.1 Specific coverage(kg/m2) 0.039 0.75 1.26
  • composition HVS-1 gave a higher coverage area than HVS-2 but with no run-off loss of composition. 92% of the standard composition was lost in the first few seconds.
  • Example 8 Application of a thickened pulp and paper manufacturing machinery cleaning composition as in example 2 and 3 to a formation wire of a paper machine
  • Example 9 Preparation of a thixotropic, water-based, alkaline pulp and paper manufacturing machinery cleaning composition with increased viscosity
