Definitions
- the invention relates to a method and an apparatus for loading fibers or contained filler with a filler by a chemical precipitation reaction, wherein the fibers or the pulp are provided in the form of a suspension having a predeterminable concentration of solids.
- fillers such as precipitated calcium carbonate (PCC) or crushed or ground calcium carbonate (GCC) are common substances used to reduce pulp content and to improve the optical properties of the fibrous web.
- PCC precipitated calcium carbonate
- GCC crushed or ground calcium carbonate
- PCC or GCC fillers are mass produced in specialized manufacturing plants that may be associated with a paper or board mill as a satellite facility.
- PCC on-line production has never been or will be considered in the paper or board industry because of the unique process characteristics required to make PCC. Instead, PCC or GCC is transported as bulk material or in the form of a suspension to the paper or board mills.
- the loading of fibers or pulp contained in a suspension with an additive, for example filler can be carried out, for example, by a chemical precipitation reaction, that is to say in particular by means of a so-called "Fiber Loading TM" process, as described, inter alia, in US Pat. No. 5,223,090 A.
- a chemical precipitation reaction that is to say in particular by means of a so-called "Fiber Loading TM” process, as described, inter alia, in US Pat. No. 5,223,090 A.
- the wetted fiber surfaces of the fiber material at least one additive, in particular filler incorporated.
- the fibers can be loaded with calcium carbonate, for example.
- calcium oxide and / or calcium hydroxide is added to the moist, disintegrated fiber material in such a way that at least part of it associates with the water present in the fiber material.
- the fiber material treated in this way is then preferably exposed to carbon dioxide in a shear field.
- a method based on the method of the cited US patent and immediately improved method for loading fibers contained in a suspension is known, for example, from German Offenlegungsschrift DE 102 04 254 A1.
- the precipitated product-laden fibers are milled to produce maximum dimensions of the precipitate product particles in a range of about 0.05 to about 5 microns, wherein the crystalline precipitate product particles are generated in an on-line process directly in the stock preparation line.
- German Patent Application DE 101 07 448 A1 discloses a method and a device for loading fibers contained in a suspension with a filler by means of a chemical precipitation reaction.
- the suspension containing the fibers is fed to a pump disperger and acted upon in this by shear forces to break up larger fiber agglomerates into smaller or even individual fibers.
- the pump disperger is used as the reactor for the chemical precipitation reaction.
- German patent application DE 101 20 526 A1 discloses a process for the production of pulp for further use for the
- the product obtained by a pulp production process Pulp first loaded by a chemical precipitation reaction with additive, preferably in accordance with the aforementioned US Patent US 5,223,090, then dried the already loaded pulp and provided for further use or put into shipping.
- the processes described in the prior art are all characterized in that the lime [Ca (OH) 2 ; slaked lime suspended in water; quicklime; Hydrated lime] or the slaked lime are first brought into contact with the fibers or pulp contained in the suspension, that is to say mixed, and then the carbon dioxide is introduced when the chemical precipitation reaction is triggered.
- a disadvantage of these methods is, in particular, that they have only a low efficiency, since the milk of lime or the slaked lime occupy the surfaces of the fibers or of the pulp and thus blocks the access of carbon dioxide.
- the chemical precipitation reaction on the surfaces becomes possible only after the carbon dioxide introduced has diffused through the layers of lime milk or dissolved lime. This makes it particularly difficult to load the surfaces inside the fibers (lumens).
- PCC precipitated calcium carbonate
- the remaining calcium carbonate (PCC) is unbound and is therefore free.
- the object of the invention is thus to provide an improved method of the type mentioned, on the one hand ensures a complete and rapid chemical reaction and on the other hand an efficient loading of the surfaces of the fibers (inside and outside) or the pulp. Moreover, an improved device of the aforementioned type is to be created, which makes it possible to carry out the relevant chemical reaction continuously, efficiently and economically. This object is achieved according to the invention in a method,
- That carbon dioxide is added to the fibers or pulp in the form of a suspension and
- Lime milk or slaked lime are mixed while the chemical precipitation reaction is triggered and largely, preferably completely completed.
- the loaded pulp can subsequently be dried and provided for further use or brought into shipping form.
- the pulp can be provided in bale form, roll form or the like for further use or for shipping.
- the pulp itself can be produced, for example, by the sulphate process and / or by the sulphite process.
- the lime or the slaked lime reacts with the introduction of carbon dioxide in the form that forms crystalline structures.
- the shape of the forming conglomerates can be significantly influenced by the amount of carbon dioxide and the rate of introduction of carbon dioxide and by the system temperature, possibly also by the prevailing flow conditions. Under the microscope, two basic types can be distinguished: the more rod-shaped or the flat or ball-like structures.
- the shape of the structure is particularly important for certain specialty papers. By way of example, mention may be made of cigarette paper which requires rod-shaped structures in order to ensure the necessary opacity at a defined porosity.
- the carbon dioxide is added to the suspension in at least one reactor upstream in the process flow and preferably heatable unit or the carbon dioxide is added to the suspension in the reactor, in which preferably delayed mixing of the suspension with lime or slaked lime is completed. Both options have their own advantages.
- the suspension is subjected to massive carbon dioxide before the chemical reaction.
- the fibers accumulate with it
- Fibers or pulp A further improvement of the loading process is also made possible by the process according to the invention in that the fibers or the pulp itself are "soaked” with carbon dioxide The lime or slaked lime thus already comes with the educt in view of the upcoming precipitation reaction
- This first possibility also allows the continuous addition of carbon dioxide and / or the continuous mixing with lime or slaked lime.
- the second possibility basically offers the same advantages, but disadvantageously the addition of carbon dioxide and the mixing with milk of lime or slaked lime can only take place in batch mode. The application rate when using this second option is reduced accordingly, but investment and even operating costs can be saved due to a simplified system design.
- the carbon dioxide can be added to the suspension under the action of shearing forces, preferably in a pump disperger;
- the carbon dioxide can be added to the suspension using mixing effects, preferably in a stationary mixing system, in particular a stationary mixer;
- the carbon dioxide can be added to the suspension in at least one stationary mixer under the influence of flow turbulences, wherein the flow turbulences can be used in a possible injection of carbon dioxide into a supply line; and / or - the carbon dioxide can be added to the suspension using at least one at least partially agitated mixing system, preferably in an agitator.
- the consistency of the suspension can be varied within certain limits. About this it may also be advantageous if even in the reactor before and / or during and / or after the addition of lime or slaked lime water, for example fresh water and / or white water, is added. This allows a subsequent adjustment of the consistency of the suspension.
- the suspension is degassed before adding the carbon dioxide by means of at least one degassing and / or that the carbon dioxide is added to the suspension under pressure. Both of these embodiments contribute positively to successful loading of the fibers or pulp in the course of the chemical reaction.
- the carbon dioxide is preferably added to the suspension as pure carbon dioxide and / or as flue gas.
- the flue gas can be taken from boilers or power plants. Both options support the loading process and the use of flue gas is generally more cost effective.
- the suspension is produced by dissolving pulp or waste paper with additives in at least one pulper or fed as non-dried substance, which is also referred to as "never tried pulp", the loading process, such as from another pulp mill.
- the reaction parameters are preferably measured in the at least one reactor and optionally used to control the chemical precipitation reaction.
- the reaction parameters which are relevant for safe and optimal process control comprise at least the pH, the temperature, the residence time, the throughput of suspension and / or lime or slaked lime.
