Mixing of substances and chemical reactions are closely interconnected. The way in which different reagents are mixed together can have a significant influence on product quality, product yield, or even on the resulting product itself. Stirred reactors are used in the chemical industry for a range of applications. They can be used for reaction, extraction, distillation, crystallization, and other processes. Depending on the reactor process and operating mode (continuous, semi-batch, or batch operation), the agitators used can be subjected to varied demands. In the petrochemical industry, emulsification, absorption, desalination, alkylation, or neutralization processes are commonly found; lubricating oils must be homogenized or sludge oils suspended. For this wide variety of mixing tasks, Geppert offers tailor-made agitators to satisfy operational and customer requirements.

Lors de la séparation thermique d'un mélange, un film mince est produit sur la paroi chauffée d'un évaporateur cylindrique ou conique. Le liquide d'alimentation passe d'abord dans un anneau de distribution situé sur le rotor. Une première distribution est faite à ce niveau. La couche uniforme formée à la périphérie est ensuite prise en charge par les pales du rotor qui étalent à leur tour le liquide sous la forme d'un film mince de min 0,5mm sur la surface de transfert de chaleur. Le concept de modèle d'écoulement dans l'évaporateur couche mince part du principe qu'une vague de proue se forme avant chaque pale du rotor. Le fluide venant de la vague de proue vient d'une zone fortement turbulente et se glisse dans l'espace entre la pale du rotor et la surface de chauffage, résultant en un transfert intense de chaleur et de masse. Cela se traduit par une bonne performance d'évaporation même avec des produits visqueux.

Die chemische Industrie stellt für viele Wirtschaftszweige die benötigten Rohstoffe her. Wichtige Industriezweige, die diese Stoffe benötigen, sind die Lebensmittelindustrie, der Automobilbau, der Maschinenbau und die Baustoffindustrie. Viele chemische Herstellungsprozesse sind auf den thermischen Austausch angewiesen, um der Reaktion Wärme zuzuführen oder zu entziehen. Hierzu werden häufig Wärmetauscher aus Metall eingesetzt, die allerdings sehr korrosionsanfällig sind.

In the treatment of drinking water, whether done conventionally or via seawater desalination, agitators are used for rapid mix, precipitation and flocculation processes. Precipitation and flocculation processes require low shear, slow-running agitators. For pH adjustments and rapid mixing faster running agitators that can blend reactor content in a flash are required. Wastewater treatment also requires a multitude of application options for agitators. In anaerobic and anoxic tanks for nitrogen removal, slow-running agitators are used to suspend and homogenize activated sludge flocs. In aeration tanks, mixer/aerators can be used for efficient oxygenation and mixing. Where waste water is purified, sludge is generated. This sludge is generally conditioned using polymers, dewatered, and then digested in anaerobic sludge digesters to generate biogas. Special agitators are required for both polymer introduction and for digested sludge mixing.

In the manufacture of semiconductors, agitators are mainly used in conditioning of polishing and cutting suspensions, etchants and other auxiliary chemicals, cleaning solutions, or in chemicals recycling. Requirements placed on stirring systems are extremely demanding. Almost always, clean room conditions prevail, meaning that drives and seals must be designed with no abrasion or leakage. Parts that come into contact with the medium, such as the shaft and stirring element, often have to be produced with metalfree surfaces due to the aggressiveness of the media and the purity requirements. Also in this area, Geppert Ruhrtechnik can look back on a very successful history. All well-known chip manufacturers belong to our client base, as well as the manufacturers of the specialty chemicals used in this field. In addition, our agitators are used in broad solar cell production areas.

Paints and coatings play a significant role in our lives. Without them, life would be dull and even monotonous. But they don’t just provide color. They perform a multitude of other tasks as well. For example, they protect objects or structures from corrosion and deterioration, thus contributing to the sustainable use of resources. Equally, special coatings can contribute to a reduction in flow resistance, or create a pearled finish that makes objects easier to clean and reduces contamination. Paints and coatings generally consist of binders, fillers, pigments, solvents, resins, and perylene, as well as additives. These substances must be mixed together homogeneously during the production process. Various agitators are used to achieve this, for example dissolvers, depending on the process step and according to the boundary conditions.

OUR IN-HOUSE TEST PLANT AND LAB In order to ensure the high quality and long service life of our agitators, we have set up an in-house plant for testing our agitators. At the end of the manufacturing process, all of our agitators undergo a specific test procedure with a final test run. Here, we can test agitators with a shaft length of up to twelve meters. When designing our agitators, we use fluid mechanics simulations in our in-house laboratory. All Geppert mixing systems are delivered with O&M Manual and worldwide technical service.

In einem Dünnschichtverdampfer wird für die thermische Trennung eines Stoffgemisches auf der beheizten Wand eines zylindrischen oder konischen Apparats ein dünner Film erzeugt. Ein Verteilring auf dem Rotor verteilt die zugeführte Flüssigkeit zunächst gleichmäßig auf den Umfang. Dann wird die Flüssigkeit mit am Rotor montierten Blättern als min. 0,5 mm dicker Film auf der beheizten Wand verteilt. Die Modellvorstellung zur Strömung im Dünnschichtverdampfer geht davon aus, dass vor jedem Rotorblatt eine Bugwelle gebildet wird. In dem Spalt zwischen dem Rotorblatt und der Heizfläche wird Flüssigkeit aus der Burgwelle einer hochturbulenten Zone mit intensivem Wärme- und Stofftransport zugeführt. Damit ergeben sich auch bei viskosen Produkten gute Wärmeübergangsleistungen. Zudem wird die Bildung von Belägen vermieden und die intensive Durchmischung schützt auch temperaturempfindliche Produkte vor Überhitzung. Beheizung:Sattdampf oder flüssige Medien Produktviskosität:bis 70.000 mPa·s Verweilzeit:< 1min Werkstoffe:Edelstahl, Titan, Hastelloy

For the thermal separation of a mixture a thin film is produced at the heated wall of a cylindrical or conical evaporator. A distribution ring on the rotor distributes the liquid evenly across the periphery. Then, the blades fitted at the rotor spread the liquid as a thin film of min. 0.5 mm over the heat transfer surface. The model concept for the flow in the thin film evaporator assumes that prior to each rotor blade a bow wave is formed. In the gap between the rotor blade and the heating surface, fluid is supplied from the bow wave of a highly turbulent area with intense heat and mass transport. This results in a good heat transfer performance even with viscous products. In addition, the formation of deposits is avoided and the intensive mixing also protects temperature-sensitive products from overheating. Heating:saturated steam or liquid medium Product viscosity:up to 70.000 mPa·s Residence time:< 1 min Material:Stainless stell, titanium, hastelloy

Despite the increasing level of digitalization, an ever-increasing demand for paper and pulp products can be observed. However, a shift is taking place from print paper qualities to packaging paper and cardboard. The wide range of paper products requires a variety of production processes. These include mechanical and chemical processes which, depending on the form and variant, produce different pulp qualities. Stirring and mixing are essential unit processes in all types of paper and pulp production. Mixing tasks range from liquid/liquid or gas/solid/liquid mixtures, through mixing of complex liquids, and include mixing of chemically reactive components. Improving and optimizing mixing processes in the paper and pulp industry can lead to end product improvements; such as increased strength, improved luster, or significant energy or chemical savings.

The pharmaceutical and biotech industry involves a wide range of mixing tasks, for which precision and consistence are of utmost importance. Particles must be evenly suspended and homogenized in liquids for filling processes. In some cases, multiple processes, such as for example heat transfer, rapid mixing, or material transport, must take place simultaneously within one reactor. Specific requirements are often placed on the drives, if for example production is carried out under clean room conditions. The surface quality of the stirring elements must always meet the highest standards; they are therefore usually electropolished. Our agitator solutions for the pharmaceutical and biotech industry are engineered and manufactured to customer-specific requirements. Selection of the agitator, as well as of the drive and sealing concepts, depends on the process and customer specifications. We will provide all the necessary design calculations, or simulate the mixing process.
