Applications Mechanical Seals Sealing Technology in Pulp and Paper Production 50 E Your partner for sealing technology worldwide EagleBurgmann – Your partner for sealing technology in the pulp and paper industry Worldwide demand for paper and paperboard in 2005 was about 360 million tons and is likely to grow to about 500 million tons by 2020 The pulp and paper industry therefore continues to be a definite growth sector If anything, developments such as the “paperless office” or “new media” have actually contributed to an acceleration in the consumption of paper With paper consumption continuing to rise, it is becoming extremely important to strike a harmony between economy and the protection of the environment This implies a careful use of wood as a regenerative material, controlled consumption of water and energy, and particularly the recycling of waste paper as a “raw material” Modern sealing technology makes a major contribution to optimized production processes and their further development Cartex-QN The paper industry today The processes needed to produce pulp and paper are highly energy-intensive If only for reasons of economy companies are concerned, therefore, to minimize the specific consumption of their mostly self-generated supplies of steam and electricity through continuous rationalization and modernization Circulating systems are used, for example, to reduce the fresh water content of the vast quantities of water required in pulp and paper production This in turn cuts the amount of waste water that is subjected to mechanical and biological treatment, usually in the companies’ own sewage treatment plants And where the chemicals used in pulp production are concerned, the biggest part is now recovered and recycled Environmental protection With its collection and recycling of old paper the paper industry is making a major contribution to easing the pressure on our environment In hardly any other sector has the recycling of raw materials attained such significance Chlorine-free bleaching is the state-of-the-art technology which has been used for many years now, and the production processes used for producing pulp are being perfected all the time to ensure that they are as environmentally compatible as possible Sealing technology more important than ever Sealing technology has an inestimable role to play if the demands of economy and ecology are to be fulfilled as well as possible Sealing systems used in the transportation and processing of the various media should function without maintenance but with maximum safety reserves Yet components in the different processing stages are being exposed to more stress than ever before from the increased use of chemicals and higher stock consistencies Mechanical seals are usually the first choice these days for use in pumps and mixers, provided they comply with an extensive catalog of requirements They must be wear-resistant, rugged and protected against dry running, have smooth surface contours with by and large no empty spaces, and be universal in application and easy to install A matter of trust A large number of major international suppliers of machinery to the paper industry trust in EagleBurgmann seals: ABS Scanpump, Andritz, Andritz-Küsters, Metso, Netzsch, Sulzer, Voith, to name just a few Service with a capital “S” Even the perfect seal calls for expert consulting, staff training and after-sales service in the event of trouble Ask us about the extensive range of services covered by our TotalSealCare® service No paper without water This simple phrase is still true today, even if specific water consumption per ton of produced paper has been substantially reduced over recent years High-quality water is a scarce resource which varies from region to region, and for an industry with a strong commitment to cost-effectiveness and the environment such as the paper and pulp industry, the challenge is to use water as efficiently as possible The industry is the fifth biggest industrial consumer of water in Germany and therefore has a particular duty to ensure that it uses the water efficiently and carefully By managing to constrict the recirculating water systems ever more, the paper and pulp industry has achieved drastic reductions in water consumption and associated waste water The specific waste water level, for example, has now been cut to less than 10 l/kg and any further reductions now only appear possible with difficulty However, the achievement of what are more or less completely closed water circulation systems has in turn led to other problems such as the accumulation of micro-organisms and harmful substances, for example, which are an impairment to the production processes LP-D for “non-flow” operation Mechanical pulp production A pressure grinder (Metso) for producing groundwood pulp, as seen during installation By raising the pressure it was possible to break up the wood structure at a higher temperature, with a higher moisture content and less stress on the product Groundwood pulp is mostly produced by mechanical means, with up to 95 % of the wood input being converted into pulp Compared with the production of chemical pulp the yield is about twice as high, although the process does consume large amounts of energy For groundwood pulp production, debarked timber is processed in (pressurized) grinders (PGW, GMP) An alternative method is to fiberize chips in refiners In this case a distinction is made between thermo-mechanical (TMP) and chemithermo-mechanical (CTMP) pulp In the TMP production process the chips are pre-treated with steam In the CTMP process the chips are additionally impregnated with a sulphurcontaining pulping solution of Na2S03 The structure of lignin becomes less tight and deformable This results in largely unharmed individual fibers with high strength and a wood-based material which is of higher overall quality See flap for explanation of code numbers and seal group selection CTMP 21 11 Steam 37 Mechanical pulp production 11 Steam 31 35 23 11 37 21 Steam TMP 37 Steam Steam 16 17 35 11 23 31 11 19 18

selection Pressure screens (Lamort) are sealed successfully with either type HJ977GN, MFL85N6 or HR10 mechanical seals, according to pulp consistency Pulp production Sulphate process Sulphite process Pulp is produced from wood chips which are broken down with appropriate chemicals at elevated temperature and pressure In contrast to mechanical pulping, this process involves the removal of the lignin Depending on the requirements on the end product the pulp, which in chemical terms is comprised of cellulose and hemicellulose, is bleached in a number of stages The current state-of-the-art in bleaching technology is chlorine-free bleaching with chemicals which work on an oxidative basis such as oxygen, hydrogen peroxide or ozone In the sulphate (or kraft) process the wood chips are boiled in an alkaline sodium solution (NaOH + Na2S) to remove the lignin from the wood Although this process subjects the fibers to the least strain and produces pulp of a very high strength, the pulp is more difficult to bleach However, since this process is suitable for breaking down every type of wood and also produces pulp of exceptionally high quality, the kraft process has become established as the most widely used process for pulp production The sulphite process removes the lignin from the wood by means of a digesting solution consisting of sulphurous acid (H2SO3) and a base (e.g Ca2+, Na+, Mg2+ or NH4+) Compared with sulphate pulp, the sulphite variety is lighter in color but not as strong Only certain types of wood are suitable for the sulphite process, of which spruce and beech are two; pine on the other hand, cannot be broken down using this process In both processes the waste materials produced during the removal of the lignin and the recovery of the chemicals are used to generate energy and steam Waste paper treatment The recycling of raw materials is a priority objective of every modern, ecologically oriented industrial society In no other sector has the collection and recycling of raw materials attained such significance as in the paper industry In 2005, 79 % of waste paper was recycled in Germany In terms of the recycling and re-use of waste paper, therefore, Germany is ahead of every other country in the world The collected paper is first sorted and pressed into bales Mixed with plenty of water and a certain amount of chemical additives it is then fiberized in so-called pulpers and sorted into slightly and heavily contaminated fractions Ink is separated with the help of chemicals and mechanical force in the de-inking process and the subsequent flotation can be skimmed as foam from the surface Depending on its ultimate use and required quality, the waste paper stock thus obtained can now be bleached, either on an oxidative (hydrogen peroxide) or reductive (formamidinosulfinic acids or dithionite) basis De-inking (flotation principle) stock pumps and screens in the de-inking plant of Stora Enso Maxau are sealed with EagleBurgmann type HR10 seals (in dead-end arrangement) Flushing with circuit water (white water) is carried out only when the medium has a high solids content The combination of face materials is SiC/SiC (d1 = 46 … 130 mm; p1 = mWC; t = 60 °C; n = 980 –1; medium = pulp (0.2 … % abs dry) with a high content of air) Pulper Voith slot sorting machines in a paper recycling plant used to manufacture standard and

(groundwood pulp, chemical pulp, waste paper pulp, fillers and other additives) are fed to the stock preparation plant where the stock is mixed The circulating water from the paper machines is used to dilute the stock according to the requirements of the chosen paper (consistencies from around 0.1 to 1.3 %), and before the stock is fed into the head box it is cleaned again The standard equipment used for mechanical paper production is the endless wire paper machine, which contrasts with the board machine on which different types of boards can be made The stock is transferred from the head box to the wire section where the water is removed from the endless web of paper Most of the water which has to be removed is removed in the wire section and the web of paper is then transferred to the press section More water is removed under the application of pressure and vacuum 10 Following the press section the web of paper, which is still damp, is forwarded to the drying section where all remaining moisture is removed by rotating drying cylinders heated by steam on the inside This is followed by the calender section, comprised of to rolls, where the paper, which is still rough at this stage, is smoothed out 30 24 Paper machine 18 18 Groundwood pulp Chemical pulp Waste paper pulp 31 20 34 24 33 22 14 See flap for explanation of code numbers and seal group selection Paper finishing Depending on the quality of paper required the paper machine may be followed by further units for upgrading the web of paper One method used for improving the surface quality and printability of the paper is coating In this operation a coating paste comprised of pigments and binding agents is applied to the surface of the raw paper In terms of the coating process itself a distinction is made between doctor blade coating, coating with film presses and new coating processes such as curtain coating and spray coating Coating is used above all for graphics papers However, even after it has been through the smoothing rolls in the machine the paper still has not achieved the quality required for highgrade writing paper and printing paper This is only achieved by calendering, in which the paper is compacted and the surface upgraded even further Here the webs of paper run through to 10 pairs of rolls in the calender which are either heated or cooled depending on requirements LP-Q 11 RGP 68 DD (Metso) at SCA Refiner grinding disc S2000 Refiner from Andritz Applications for mechanical seals Fiberizing processes Refiners Single disc refiners have a fixed and a rotating disc whereas double disc refiners have two counter-rotating discs The fiberized material leaves the refiner together with the process water and is either forwarded directly to the sorting section or is ground further in a second refiner stage, normally under atmospheric pressure, until it has reached the required degree of grinding Operating conditions: Temperature … 200 °C Pressure … 16 bar Sliding velocity … 40 m/s Axial displacement of the shaft 0.2 … 100 mm Medium: Wood fiber, lignin, water(steam) Seal solution: EagleBurgmann H-D double seal with a stationary spring arrangement protected from the product, and rotating seat Flushing on the product side prevents the medium from entering the sealing compartment (as used, for example, in Andritz, Pallmann and Metso refiners; where water flushing is on the product side these seals last for about to operating years on average) 12 Pressure grinding machines When it comes to grinding processes, pressure grinding is now the most widely used method because it produces a higher quality of pulp The fibers are loosened by grains of corundum embedded in the surface of the grinding stone The fibers isolated from the tissue structure in this way are sprayed with jets of water to remove them from surface of the stone, to land in a grinding trough below the stone Operating conditions: Temperature … 150 °C Pressure … bar Speed … 350 min–1 Shaft diameter … 450 mm Shaft displacement: Axial … ± mm; radial … ± mm Medium: Groundwood pulp, water(steam) Seal solution: EagleBurgmann HSSHRS8-D4 double seal of cartridge design; rotating seat, stationary spring arrangement protected from the medium, seal faces with hydrodynamic grooves for better lubrication of the sliding faces, clean water as the buffer medium Seals in pressure grinding machines (from Metso, for example) have to be as reliable as possible This is because every repair necessitates dismantling the entire rotating unit of the pressure-grinding machine (shaft, grinding stone, bearings and seal), resulting in at least three days of lost production, including shutting down and starting up the grinder With the service life of the grinding stone generally being about four years, the seal is increasingly expected to last just as long Metso refiner for groundwood pulp production Pulp transportation Centrifugal pumps (stock pumps) The design of pump to be used will vary according to the consistency of the pulp (thin, medium or thick pulp) The vast majority are pumps for thin pulp with a pulp consistency of up to a maximum of % abs dry There are also special forms of thin pulp pumps such as, for example, fan pumps and digester pumps So-called MC pumps (MC = medium consistency) are used for conveying pulp in the medium consistency range of between to 18 % abs dry These are used mainly in the bleaching stage, but are also widely used for the processing of waste paper as well Centrifugal pumps are not suitable for thick pulp Operating conditions: Temperature 20 … 170 °C Pressure … 25 bar Sliding velocity … 30 m/s Resistance to chemicals pH … 14 Sulzer Ahlstar UP equipped with a Cartex-DN (double seal) Medium: Water with pulp; abrasive contamination and solids; poor lubrication characteristics, to some extent harmful to the environment Seal solution: ■■ MG12, MFL85N, HJ977GN component seals ■■ e.g EagleBurgmann MG12S14/ d1G1 rubber bellows single seal with a rugged spring with unrestricted allround flushing, and no dynamic O-ring The special feature here is the enlarged gap between the shaft and the inner diameter of the seat ■■ Cartex-SNO, LP-S single cartridge seals, e.g LP-S-S32-E10/60-00, a semi-cartridge seal adapted to the machine featuring a stationary super sinus spring arrangement protected from the product, rotating seat with double elastic support, shrink-fitted sliding faces, smooth external contours on all seal parts in contact with the product ■■ Cartex- DN, LP-D double cartridge seals, e.g EagleBurgmann CartexDN/60-E31 double cartridge seal with a pressurized buffer water supply, stationary and encapsulated springs, rotating seat, self-closing in case of pressure reversal (double balancing), can also be used as a single seal with quench, quick and easy to install The EagleBurgmann Cartex is one of the most successful cartridge seals available, and that applies to pulp and paper production as well Just some of the companies who use it are Stora Enso, Norrsundet/Sweden, Iggesund Paper, Iggesund/Sweden, Smurfit Kappa, Pitể/Sweden, Zellstoff Pưls, Austria 13 Mixing processes In the pulp and paper industry, mixers are used either for blending different media, homogenizing ready-prepared mixtures or preventing existing mixtures from segregating again Given the diversity of tasks that mixers are required to fulfill they also vary considerably in terms of design, e.g pumps (largely horizontal centrifugal pumps) or agitators with top, bottom or side drives HGH 14 Sorting Operating conditions: Temperature … 180 °C Pressure … 18 bar Speed … 1,500 min–1 Shaft diameter … 240 mm Medium: Pulp suspension with a consistency of 0.1 % to % abs dry, chemicals Seal solutions: HGH, MG, HJ, LP-D, MR-D and even Cartex®, e.g EagleBurgmann HGH210/10-E6 half-split mechanical seal for a chest agitator at Sappi Lanaken/Belgium Installation is from the outside, horizontal (or vertical) It is important that there is sufficient axial latitude to enable the seal housing and seat housings to be pulled back far enough to allow access to the sliding parts The only parts that are split are the actual wearing parts, such as the seal face, the seat and the O-rings They can therefore be replaced easily without the need for complete dismantling Operation is with flushing into the product (which prevents concentrations of the product building up on the sliding faces) and a quench on the atmospheric side If a stand-still seal is fitted it is also possible to carry out inspection work on the seal without interrupting operations, even with a full container The job of the sorting machine is to remove foreign material such as sand and undesirable form elements such as splinters The sorting operation is carried out at a high level of dilution (pulp consistency of no more than % abs dry) to ensure that the foreign material can move with relative freedom Vertical sorters operating under pressure are normally used these days The advantages of these kinds of plants are that they offer high throughputs, are insensitive to load variations and have closed systems of pipework which means they lose less steam and heat Operating conditions: Temperature … max 80 °C Pressure … max 12 bar Speed … 2,500 min–1 Shaft diameter … 175 mm Medium: Pulp suspension with a maximum pulp consistency of % Axial displacement of the shaft ± 1mm Installation position: vertical Seal solution: HR, LP-D, HRS-D e.g EagleBurgmann HR10S2/100G11E1 single cartridge seal for a Voith sorter with rotating seat and stationary, group spring arrangement protected from the medium LP-D-ST-D15/130-DE double seal for a Metso Tampella sorter in non-flow operation without buffer fluid system, with substantially reduced water consumption in use at the Palm paper factory in Wörth Paper finishing Eccentric screw pumps Eccentric screw pumps are used mainly for the finishing of the raw paper, e.g for the preparation of coating paste The media used here are generally characterized by a high solid content, high viscosity and tendency to stick, which means they have poor lubrication properties Operating conditions: Temperature approx 40 °C Pressure 1… bar Speed … 400 min–1 Medium: Coating pastes with latex Seal solutions: EagleBurgmann MG1S50/65-G6 single seal with elastomer bellows, seal face with knife edge EagleBurgmann Cartex-DN/55-E2 Double cartridge-style seal, pressurized buffer medium (as used, for example, by BASF in Ludwigshafen: Pulp & Paper Test Center, dispersing plant) Calender rolls Heat is generated by the high pressing forces and friction involved, which has a strong influence on the results of the calendering process For heavy glazing, therefore, the steel rolls have to be cooled, whereas light glazing requires them to be heated Operating conditions: Temperature … max 200 … 300 °C Pressure … max bar Speed … 600 min–1 Shaft diameter … 460 mm Medium: Thermal oil Special features: Expansion of the long rolls under heat Seal solution: EagleBurgmann MFLW81 metal bellows seal for high temperature applications (as in Küsters calender rolls, for example) Calenders (Kleinewefers; Küsters): EagleBurgmann MFL W80S1/475 seals are used successfully to seal off the oil used for heating the rolls and for lubricating the bearings (p1 = … bar; t = 20 … 200 °C; n = … 462 -1; axial displacement ± mm) 15 EagleBurgmann BestFlow: Temperaturecontrolled valve for ‘non-flow’ operation Greater cost effectiveness thanks to reduced water consumption As little water as possible, as much water as required EagleBurgmann FLC200: Control unit for the individual setting and monitoring of pressure and flow rate at the seal 16 The costs of water and sealing water management have become increasingly important issues in the paper and pulp industry over recent years Growth in environmental awareness, stricter environmental regulations, water recirculation systems which are largely self-contained, the increasing cost and effort associated with supplying and treating the water and higher operating costs in general have all led to a change in approach and are the main reasons for this development An approach which protects resources is not only good for the environment - saving water and energy also makes it possible to achieve substantial and above all measurable reductions in costs Furthermore, investigations have also shown that actual consumption levels are often above recommended levels because this is believed to be necessary for safety reasons Many producers of pulp and paper are therefore keen to run seal systems with methods of operation which, while meeting requirements for necessary operational safety, use only minimum amounts of water or, where possible, even dispense altogether with the use of sealing systems involving flushing or buffer water Major potential for savings Mechanical seals, single seals with or without flushing and/or a quench, and double seals with pressurized water supply all operate in different ways and these differences have a major influence on the amount of water they use For example, the use of a supply unit along with the operation of a double seal can, subject to specific operating conditions, achieve savings in buffer water consumption of up to 97 % compared to operation with an open flow Low outlay, big effect: A range of different control units can be used to control and reduce the water supply, depending on each specific application EagleBurgmann offers a range of systems designed to help save water without any impairment to the safe and reliable operation of the mechanical seals EagleBurgmann FLC100 Flow Controller: A control unit for a constant, pre-defined and pressure-independent flow EagleBurgmann Thermosiphon System: A supply unit with a closed circuit for double seals in which the only water consumption is the leakage on the seal, which has to be replaced 17 Selecting mechanical
