Static mixing to your advantage 70,000 references Static mixers are tubular internals of appropriate shape and strength to cause desired mixing and dispersion effects as the fluid flows around suitably arranged motionless mixer parts. The fluid flow is provided by pumping. In practice, small volumes, low maintenance,. simple installation and cleaning and excellent. reliability characterize the static mixer. Pump Laminar mixing Laminar mixing is achieved by repeated division, transposition and recombination of liquid flowing around a static mixer. The components to be mixed are spread into a large number of fine layers. A static mixer consists of several identical mixing elements. The more mixing elements, the finer the layers. The finer the layers, the better the homogeneity of the mixture. 0691 2724-03 Static Mixer 0606 2722 Laminar mixing in the Sulzer SMX mixer shown with Laser Induced Fluorescence Turbulent mixing Some turbulent mixing is observed even in an empty pipe. By installation of a static mixer, however, the distance required to achieve a good homogeneity is reduced by a factor 10 and more. A static mixer has one or several mixing elements generating eddies in the flow. Any kind of inhomogeneity will be dissipated by strong cross currents within the mixing elements and downstream. 0605 2701 Turbulent mixing with eddies in the CompaX mixer shown in a CFD simulation 5

Chemical Process Industry over 15,000 references 4588 4059 Thousands of references document the versatility of Sulzer mixers in the chemical process industry. The applications range from mixing of liquids at various viscosities, mixing including reaction, gas liquid contacting, mass transfer and absorption, gas mixing and liquid evaporation. In order to cope with corrosive chemicals the mixers are available in a wide range of materials. Customer benefits Uniform and consistent process conditions in respect to - Concentration - Temperature - Residence time distribution - Consistent product quality - High yield - High selectivity for continuous reactions - Low energy consumption - Low volume of the mixer/reactor - Low volume/hold up of the processed products - Low maintenance cost (no moving parts) - Easy start up and operation 0606 2718 SMV EDC reactor Main Applications Dilution of liquids In-line mixing of various additives Liquid and gas flow conditioning Dispersing of liquids Evaporation of liquids into gas streams Gas/liquid contacting Absorption of gases in liquids 10 0694 2720 SMV Spray evaporator

Energy DeNO x over 1,800 references 0606 2729 Sulzer mixers have enormous potential in energy technology, and their use is widespread. In gas treatment, small amounts of reactive agents are often added to high volume flows and distributed very uniformly within a short distance over the entire channel cross section. In other applications, it is necessary to uniformly distribute the concentration and temperature of a process feed upstream of a catalyst or to dissolve gases into liquids and to generate fine, uniform bubbles in insoluble liquids. Sulzer has the proven mixing technology and products for these growing processing technologies. SMV gas mixer for challenging space limitations - Excellent mixing performance for shortest space requirements - Fits any duct dimension - Well suited for dosing small amounts of additive - Low pressure drop 0692 2756 0606 2726 SMV gas mixer for flue gas treatment CDF simulation for a DeNO x application Contour mixer for gas conditioning The new Contour mixer provides effective large scale eddy mixing - For any required gas conditioning task - At lowest pressure drop in the industry Main Applications Injecting ammonia into flue gas for NO x removal Gas conditioning Oil/water dispersions 0606 2716 Ideal flow conditions in the Contour mixer 11

Water & Wastewater over 4,500 references 0691 2724 02 / -3 Mixers for water/wastewater treatment In the field of water and wastewater treatment, mixing and contacting are key unit operations. There is a fundamental influence on the performance of individual process stages or even on the results of the entire process itself. The ever increasing demands on water quality drive continuous improvement of the purification processes. This has led to an increasing number of installations of in-line static mixers for mixing and contacting operations in the water and wastewater sector. The use of static mixers in the water/wastewater industry saves costs by reducing additive consumption. Customer advantages - High specific exchange area leading to efficient mass transfer - High utilization rate of the ozone gas - Short installation length - Low pressure drop - Guaranteed absorption degree of the gas - Steady absorption degree at turn-down and turn-up conditions 0605 2718-4 CompaX and SMV mixers in FRP for seawater desalination Main Applications Admixing of flocculent into water or sludge ph control or neutralization Oxygen enrichment of drinking water Ozonization of water Admixing of disinfectants Admixing of additives for the sea water treatment 0692 2735 The SMF mixer in polypropylene for sludge treatment 12

Food Processing Industry over 4,000 references Static mixers and heat exchangers have been used in the food industry for over 30 years. Sulzer mixers offer an outstanding mixing performance combined with excellent cleaning and sterilization abilities, an essential requirement for continuous food processes. They are used in various branches in the food industry (e.g. dairy, sweets, beverage, ingredients, etc.). Applications range from blending, dispersing, foaming, aerating, conditioning, heat exchange to various other operations in the liquid, gas and sometimes solid field.

Fiber Production over 2,200 references Static mixers and coolers are used in fiber production to ensure optimal mixing, homogenization and cooling of the polymer melt (PET). This provides a basis for an economic production of man made fibers of consistently high quality. Melt homogenization In spinning plants SMX mixers are installed prior to line splitting, at the spin position and in the spin packs to avoid fiber breakage. 0609 2715 SMX melt homogenizer Admixing of additives The SMX mixer handles great viscosity differences as well as dispersive mixing. The highly effective mixing characteristics prevent unnecessary over dosing of additives and result in substantial cost sa-. vings. Polymerization Due to the narrow residence time distribution in a SMX tubular reactor, a spinning polymer is produced with a narrow molecular weight distribution and low content of by-products. Cooling / heating In cooling applications the SMR structure achieves mixing, boosts the heat transfer and provides plug flow. Very low temperature driving force and low pressure drop operation without maldistribution or plugging are possible. In addition, the capital and operating cost of ancillary equipment like pumps is up to 25% lower than in the case of multitube heat exchangers filled with mixing elements. Main Applications Homogenization of melts Mixing of additives Cooling of polyester melt in direct spinning plants Gentle heat-up of spinning solutions Polymerization in a plug flow reactor 0690 2750 SMR heat exchanger 16

Plastics Processing over 15,000 references 0698274102 A perfectly homogenized melt is one of the most important requirements in achieving high quality polymer products. Irregularities, such as color streaks, flow lines, uneven wall thickness, flow variations etc. lead to increased reject rates and increased production costs and are often the result of poor quality melt homogenization. The Sulzer mixing head SMK-R is an efficient tool developed to provide consistent melt homogeneity in injection molding machines. For extrusion and blow molding applications, the Sulzer Melt Blender SMB-R is used to achieve the same results. These Sulzer mixers provide a larger processing window, allow higher throughputs and give improved product quality while ensuring that products are produced more economically. The benefits for the extrusion process - Consistent product quality - Uniform wall thickness - Elimination of flow lines - Closer tolerances SMB-R for extrusion SMK-R mixing head for injection molding The benefits for injection molding technology - Reduced color costs - Lower reject rates - Faster cycle times - Improved mixing of regrind - Fast payback 0601 2702-2 Additional products 0698 2732-2 0604 2719-1 0604 2716-1 0603 2708 Polyguard The mixer for PVC and rubber extrusion VIP The dynamic mixer with. intermeshing pins Optifoam The technology for foamed. plastics 17
