Optimizing Thermal Processes in Carbon Manufacturing with Simulation

Guest Bojan Jokanović July 5, 2018

Guest blogger Bojan Jokanović of SGL Carbon GmbH, one of the world’s leading manufacturers of carbon-based products, discusses the optimization of thermal processes in the carbon industry. Carbon products are used in many industries, including semiconductors, car manufacturing, ceramics, and metallurgy. Properties of graphite including high-temperature stability, good thermal and electric conducting behavior, and high chemical stability make this material unique. However, carbon manufacturing is an energy-intensive industry. We must build digital process chains to optimize processes and minimize costs.

Multijet tubular reactors are used to manufacture polymers such as polyester. The turbulent flow that occurs in this type of reactor can affect the manufacturing process, including the reaction kinetics, fiber quality, conversion, and yield. By developing a reactor model that fully takes into account both the fluid dynamics and chemical reactions, you can optimize a reactor design for efficient and reliable polymer production.

Batch reactors are used to manufacture a wide variety of products in the fine chemical, pharmaceutical, and food industries. In some cases, fine chemical processing may require more consistent operating conditions than batch reactors can offer, and continuous plate reactors may then provide better control of the process. Chemical modeling can help in the design of continuous plate reactors that are optimized for thermal control and product purity.

Pablo Rolandi from Amgen delivered a keynote presentation at the COMSOL Conference 2017 Boston. The topic? How Amgen is moving beyond modeling and simulation for biopharma development. Rolandi shared five examples that illustrate this idea across both biologic and synthetic medicine applications. If you missed his presentation, you can watch a recording of the video and read the highlights of what he discussed here.

Previously on the blog, we discussed why surfaces are sites of special chemical interest and discussed the theories used to describe reactions at surfaces, including when those surfaces are described within homogenized models of porous media. In this blog post, we’ll discuss how chemicals behave when they become attached to a surface by adsorption. Adsorption plays an essential role in many catalytic and sensing processes, so let’s consider how it can be built into your chemical models.

Steam reformers are commonly used for power and energy generation processes. To accurately analyze the performance of a steam reformer design, you need to be able to couple mass, energy, and flow equations. Using the COMSOL Multiphysics® software, you can set up a model of a steam reformer that represents its real-world behavior and operating conditions.

You can easily describe composition- and temperature-dependent fluid properties using the thermodynamic properties database, available as of version 5.3a of the COMSOL Multiphysics® software. For reacting systems, the database computes enthalpy of formation and enthalpy of reaction. For fluid flow and heat and mass transfer, the database can compute viscosity, density, heat capacity, thermal conductivity, and diffusivity of liquids and gases. For systems with several phases, the thermodynamic properties database computes the composition of the phases at equilibrium.

Wet chemical etching is used to form patterns on surfaces, with applications including the production of integrated circuits, MEMS devices, and pressure sensors. This process has been around for hundreds of years, and was a favorite method of Old Master Rembrandt van Rijn. The optimization of chemical etching was historically a matter of trial and error, but in this blog post, we’ll show how to model the process in the COMSOL Multiphysics® software.

In a previous blog post, we discussed why surfaces are special in chemical reactors. In this blog post, we’ll see how surface area is maximized in reactor structures such as pellet beds, and how we can simply and accurately simulate fixed-bed reactors in spite of their local geometric complexity and the importance of microscopic diffusion.

Research shows that microgravity exposure has an effect on the human body, such as by suppressing immune cell activity. This phenomenon also affects cancer cell migration. Making use of this fact can lead to the identification of new therapeutic targets for metastatic cancer cells. In this blog post, we’ll discuss how a research team used the COMSOL Multiphysics® software to design a culturing system to study cancer cell migration in microgravity.

Zone electrophoresis separates different species in a sample into distinct well-resolved peaks, giving scientists the ability to analyze substances like proteins and nucleic acids. Improving this electrophoretic separation technique requires us to accurately model the transport and separation of these species. Here, let’s look at how the COMSOL Multiphysics® software can be used to simulate the movement of species during zone electrophoresis.
