22 ACHEMA DAILY #1 | MONDAY, AUGUST 22, 2022 Mechanical/Thermal Processing Carbon Capture and Utilization Electrochemical CO 2 Capture and Utilization Pilot Plant Electrochemical reduction of CO 2 Source: JKU Linz Competitive technologies for decarbonizing production processes in industrial sectors, such as basic chemicals, steel, and cement, are indispensable for minimizing the adverse effects and high costs of climate change. Capturing and utilizing CO 2 emitted from industrial sites can allow basic materials to be manufactured in a climate-neutral manner, which will reduce the CO 2 imprint of downstream sectors of the economy. CO 2 emissions are the primary driver of global climate change. Around 35 trillion metric tons of CO 2 were emitted worldwide in 2020. The resulting complex consequences will significantly impact society, ecosystems, and the economy in the coming decades. The consequences of climate change for companies are diverse. On the one hand, extreme weather phenomena can damage production sites, cause shortfalls in supply or create disruptions in the supply chain. On the other hand, new technologies, markets, and legal regulations are emerging in the course of societal changes, resulting in additional expenses or directly impacting existing products, services, and assets. In particular, escalating CO 2 prices are putting companies under increasing pressure. GIG Karasek is now developing a pilot plant along with Johannes Kepler University Linz ( JKU Linz), for capturing waste CO 2 from industrial processes and converting it into various valuable products using an electrochemical reactor cell. JKU Linz and GIG Karasek initiated the project to recycle CO 2 through electrochemical reduction into basic chemicals such as CO, formic acid, acetic acid, and fuels, such as hydrogen, methane and ethanol. Apart from the development of novel catalysts, the research cooperation of this project includes planning the construction of a pilot plant for testing and optimizing the process solution. The first plant with several cells connected in series should be ready for industrial use by the end of 2023. The pilot plant will, in turn, provide the basis for the design and dimensioning of large-scale industrial plants. A market launch will then be possible based on this scale-up concept. CO 2 utilization is achieved with the help of a specially designed electrocatalyst and a suitable reactor cell. The electrical energy required for the conversion is supplied from renewable energy sources, enabling a fully sustainable and climatefriendly cycle. Chemists refer to a reaction in which a product is made from low-cost building blocks as a “dream reaction” in a one-step process. Therefore, valuable materials can be produced in a much more energy-efficient way using the catalytic cycle. Hydrogen, for example, can be generated directly, whereas, in other processes, it has to be produced in a further, energyintensive step. However, the reactor cell with an integrated catalyst alone is not enough to establish the technology. The decisive factor is optimum integration into the surrounding periphery to ensure the most energy-efficient and clean operation possible. The reactor cell forms the core, but it must be made operational in the overall system in terms of application technology. A CO 2 reduction plant is applicable in many industrial sectors, e.g., to utilize CO 2 in flue gas from industrial plants. The following outlines the overall process of CO 2 capture and utilization using flue gas as an example: Safomi-IEC-Adapter für Maxxdrive-Industriegetriebe in Kombination mit Antriebsmotor Mehr Betriebssicherheit, weniger Bauteile IEC-Adapter für Rührwerke Bild: Nord Drivesystems Speziell für Rührwerke hat Nord den Safomi-IEC-Adapter entwickelt. Wird er anstelle eines Standard-IEC-Adapters am Rührwerksantrieb eingesetzt, führt das zu einer höheren Betriebssicherheit und einem geringeren Wartungsaufwand. Vor allem aber verfügt er über ein integriertes Ölausgleichsvolumen. Deshalb kann auf Ölbehälter und -schläuche sowie den leckage- und verschleißanfälligen Wellendichtring zwischen Getriebe und IEC-Zylinder verzichtet werden. Safomi • Flue gas is fed into the reactor cell, powered by green energy, and converted. • The resulting product stream contains many components and must then be separated, distilled, and concentrated. • The end product is hydrogen, ethanol, methane, and other high-carbon compounds. They can be processed into plastics or stored as fuels and transported for further use as needed. • Byproducts include chemical feedstocks such as formic acid, acetic acid, and a variety of other chemicals that can be sold on the market at high prices. With this technology, companies can convert millions of tons of CO 2 per year into highquality chemical products that can be directly reused in industrial processes or used to manufacture a wide range of products. Electrochemical CO 2 utilization can also be a possible solution for storing fluctuating renewable energies. Surplus wind or solar energy that cannot be fed directly into the power grid and used could be converted electrochemically into methanol, for example. Under ideal conditions, the conversion of 1 t of CO 2 equivalents could store nearly 1,400 kWh of energy. When needed, the methanol can then be used again, for example, as fuel in a direct methanol/ethanol fuel cell (DMFC). scj GIG Karasek Hall 4.0, Stand H24 gibt es für Maxxdrive-Stirnradgetriebe in den Baugrößen 7 bis 11 und damit für maximale Abtriebsdrehmomente von 25 bis 75 kNm.

Flammable materials and complex processes, often at high pressures and temperatures, make oil-and-gas one of the most challenging sectors of industry in terms of safety. Tigron actuators meet the demanding requirements of oil-and-gas applications, from production, storage and transport to downstream processing and refining. They are Atex and IECEx certified for the highest gas group IIC T4, which includes hydrogen, and additional approvals are also in progress. A wide 1803516-14.indd 2 Source: Auma Riester temperature range from -65 to 75 °C, IP 68 protection and an extremely resistant powder coating ensure that Tigron devices operate safely and reliably in harsh environments. The smart actuators are available in different sizes and combinations to suit nearly any valve automation task, including the high-precision operation of control valves and choke valves. Tigron combines high-quality design with outstanding ease of operation even when wearing gloves, thanks to its robust Combi-Switch. Operation via magnetic pen is available for extreme conditions. A commissioning assistant makes setup easy and safe. Tigron actuators provide non-intrusive setup without requiring additional tools for commissioning. In hard-to-reach locations, or where vibration is a problem, the controls can be mounted separately from the actuator. Powerful electronics, high-performance sensor systems and a wide variety of interfaces ensure that Tigron actuators are future-proof as digital transformation advances. Intelligent diagnostics facilitate predictive maintenance to help reduce unplanned downtime. mpb Auma Riester Hall 8.0, Stand C23 Erweiterung für Zahnradpumpen Pumpensteuerung Die Pumpensteuerung Witte Core Command dient als Erweiterung der Witte-Zahnradpumpen und ist speziell auf diese abgestimmt, kann aber auch für Pumpen anderer Hersteller eingesetzt werden.
