Product catalog summary
Introduction to Static Mixing Technology
Static mixers, also known as motionless mixers, are used for mixing, dispersing, reacting, and heating/cooling materials with varying viscosities and flow rates. They ensure homogeneity in concentration, temperature, and velocity through mixing elements oriented for both horizontal and vertical mixing.
Unit Operations and Industries
Static mixers are applied in mixing/blending, mass transfer, and heat transfer operations across industries such as polymer production, petrochemicals, food processing, and pharmaceuticals.
Homogeneity Achieved with Static Mixers
Homogeneity is quantified using the Coefficient of Variation (CoV), which measures deviations in variables like temperature and concentration. Tables and figures in the document illustrate the number of mixing elements needed for specific homogeneity levels.
Equipment Scope of Supply
StaMixCo offers various static mixer designs, with a rating system to help select the appropriate mixer based on application needs, cost, and process suitability.
Heat Exchangers
Static mixers enhance heat transfer in heat exchangers, available in monotube and multitube configurations, improving heat transfer efficiency.
Plastic Disposable Static Mixers
These cost-effective mixers are suitable for applications with similar viscosity and volumetric ratios, with designs like Type H-P and Type GXF for different mixing difficulties.
Computational Fluid Dynamics (CFD) Computer Modeling
CFD technology optimizes mixing, velocity, pressure, and temperature profiles in process equipment, enhancing performance in continuous processing applications.
Overview: The document discusses CFD modeling and physical flow models to optimize process equipment, focusing on SCR systems for DeNOx applications.
Key Sections:
  • CFD and Physical Flow Models: CFD models and 1:12 scale pilot plant models verify CFD results, optimizing mixing, temperature, velocity, and pressure profiles in SCR plants.
  • Applications in Industries: Combining static mixing, flow conditioning, and CFD technology benefits chemical processing, oil refining, and power generation industries, ensuring well-mixed feedstock and uniform profiles for catalytic reactors.
  • Power Generation Industry: Over 100 projects involve SCR/DeNOx abatement plants and power plant optimizations, using techniques like liquid ammonia pre-vaporization and injection through a grid.
  • Company Information: StaMixCo, with FlowTech AG, offers CFD modeling and pilot plant testing services, leveraging over 50 years of mixing technology experience.
Figures:
  • Figure 11.1: Shows a CFD model and pilot plant model for a 350 MW SCR plant.
  • Figure 11.2: Depicts a CFD model of a Tail End SCR unit optimizing mixing and thermal homogenization.
  • Figure 11.3: Illustrates a rectangular cross-section X-Grid Static mixer and Rectifying Grid for a 660 MW SCR plant.

In the early development of static mixing technology (1970's), vendors defined mix quality as the number of layers formed by a particular static mixer design and used this layer generation theory to compare performance. Claims of the formation of millions of layers we made which in reality could only be optically verified up to about 200 layers. In the 1980's, a tremendous amount of research was conducted which allowed for a technically correct and rational method of quantifying homogeneity. The method involved local measurement of a meaningful variable such as temperature, concentration, electrical...

Equipment Scope of Supply Unit Operations rely on specific mechanisms to accomplish their function. There is no one piece of equipment that is best suited for all unit operations. Static mixers are no exception to this general rule. For this reason, StaMixCo manufactures a broad range of static mixer designs of different geometric structures. This allows us to make an unbiased recommendation as to which design is best for a specific application. If our equipment is not best for your specific application, we will tell you so and recommend a supplier who can assist you. Below is a short guide that...
