34 ACHEMA DAILY #3 | WEDNESDAY, AUGUST 24, 2022 Engineering/Contracting Auffangwannen aus Kunststoff oder Stahl Sicher und geprüft AchemaDailyAd_2.pdf - August 8, 2022 x Asecos bietet mit seinen geprüften Auffangwannensystemen aus Kunststoff oder Stahl optimalen Schutz für Mensch und Umwelt: Sie sind zertifiziert und geprüft. Das Wasserhaushaltsgesetz (WHG) legt in § 62 fest, dass Behälter, in denen wassergefährdende Flüssigkeiten gelagert werden, durch geeignete Auffangwannen gegen ein Auslaufen geschützt sein müssen. Die zugelassenen Auffangwannen bieten hier das entsprechende Rückhaltevolumen. Sie verhindern das Auslaufen der gefährlichen Chemikalien in den Arbeits- oder Lagerraum, wodurch die Gefahrstoffe ungehindert über z. B. den Abfluss ins Abwasser gelangen könnten. Je nach Anforderung, werden wassergefährdende Flüssigkeiten in Wannensystemen aus Stahl oder Kunststoff gelagert. Kunststoff-Auffangwannen, zumeist aus Polyethylen (PE), werden aufgrund ihrer hohen Materialbeständigkeit für die Lagerung aggressiver Chemikalien wie Säuren oder Laugen verwendet. Die PE-Auffangwannen von Asecos verfügen über eine allgemein bauaufsichtliche Zulassung, die vom Deutschen Institut für Bautechnik (DIBt) auf Antrag erteilt wird. Bei der Aufstellung im Freien müssen die Auffangvorrichtungen gegen Niederschlag geschützt sein. Entzündbare und/oder wassergefährdende Flüssigkeiten, wie mineralische Öle oder Lacke, müssen in Auffangwannen aus (verzinktem) Stahl gelagert werden, die nach der Stahlwannen-Richtlinie (StawaR) gefertigt und zertifiziert sind. Diese legt fest, dass Stahlauffangwannen flüssigkeitsdicht, korrosionsgeschützt und beständig gegen den gelagerten Stoff sein müssen. Für die Lagerung entzündbarer Flüssigkeiten werden Auffangwannen aus Stahl verwendet, da diese selbst im Brandfall formfest bleiben. Für die Anforderungen an das Auffangvolumen und die Lagerung gilt laut WHG: Eine Auffangwanne muss mindestens 10 % der insgesamt eingelagerten Menge, wenigstens aber PE-Auffangwanne mit verzinktem Gitterrost den Rauminhalt des größten gelagerten Gebindes, aufnehmen können. Soweit in Wasserschutzgebieten die Lagerung zugelassen ist, muss die gesamte Lagermenge (100 %) zurückgehalten werden können. Bei der Lagerung mehrerer Flüssigkeiten in einer Auffangwanne sind ggf. bestehende Zusammenlagerungsverbote Bild: Asecos zu beachten, um eine Reaktion zu verhindern. Es gilt daher nicht nur die Beständigkeit der Auffangwanne gegen die Stoffe, sondern auch die Gefahr einer exothermen Reaktion zu prüfen, die die Statik der Wanne zerstört. bec Asecos Halle 4.1, Stand A78 Materials Technology High-Performance Alloys Source: VDM Metals VDM Metals’ new Alloy 699 XA VDM Metals, a leading company in high-performance alloys, is using ACHEMA to present its product portfolio of materials especially designed for the chemical process industry and plant engineering, and in particular for high-temperature applications in combination with aggressive corrosion conditions. One highlight is the new VDM Alloy 699 XA, which is attracting attention thanks to its combination of metal dusting resistance, excellent processability and weldability. In addition to its resistance to metal dusting corrosion, the material is characterized by its good thermo-mechanical properties and microstructure stability. VDM Metals offers 699 XA in the form of bar, sheet, plate, wire, welding rods, powder and seamless tubes. VDM Metals was founded in Germany in 1930 and has been part of the Acerinox group since 2020. In many key technologies, high-performance alloys from VDM Metals are indispensable for the industrial-scale implementation and safe control of essential processes in hot or corrosive environments. Safety and reliability are very important for any project in the chemical process industry. Whether the application is in plant engineering, process development or maintenance, VDM Metals meets customers’ needs for demanding materials. but VDM Metals Hall 11.0, Stand C59

The supply into these plants or the transfer to other parts of the plants is carried out via coupling stations. To ensure the required high quality and level of safety in the process, it is essential that the connections are made correctly, reliable, and, if necessary, traceable. Incorrect or incorrectly made connections can result in production downtime, production waste, increased need for cleaning, plant down time, and, in the worst case, hazardous mixtures and equipment damage. Process media used in chemical plants are often also hazardous substances. The automatic identification of coupling points at the coupling stations via RFID means that the correct connection can be checked reliably and automatically without additional time investment. If an inadvertently incorrect hose connection is detected, the automation environment prevents pumps 1791257-41.indd 2 Automatic identification of coupling points at hose stations via RFID reliably checks the correct connection RFID technology offers safety in process plants. With the help of RFID read/ write heads and the associated transponders, components can be clearly assigned in the process. Two examples of the use of RFID technology are described below: hose recognition and traceability during sampling. from being switched on or a process from starting up that would otherwise have led to high consequential costs. Traceability at the Sampling Point Another possible application of RFID in process technology plants is traceability at the sampling point. The quality requirements in process industry production plants are increasing and the associated documentation required is increasing with them. This is where automatic identification technologies such as RFID, in conjunction with software system solutions, can support and significantly simplify processes. For both applications, Pepperl+Fuchs offers RFID read/write heads for use in industrial ambient conditions and hazardous areas. Using the control interfaces in the Identcontrol series, the read/write heads can be connected to programmable logic controllers, process control systems, or other IT backend systems. If a sampling point in a production plant is equipped with an RFID read/write head and the sample container has an associated RFID tag, the container is identified during sampling and a data set is generated that contains, for example, the sampling point, date, time, product, and batch number. In the laboratory, the RFID tag uniquely identifies the sample and calls up the corresponding data set to which the laboratory results are added. This saves time and guarantees error-free allocation of laboratory results to the relevant product batch. Compact Devices with Atex Approval The IPH-30GM-Ex (LF, 125 kHz) and IQH1–30GM-Ex (HF, 13.56 MHz, ISO 15693) RFID read/write heads from Pepperl+Fuchs are two compact devices with Atex approval for Zone 1 and Zone 21 that can be used for these applications. Both devices are suitable for connection to the proven Identcontrol system and can be connected to different fieldbus systems or industrial Ethernet. The rugged stainless steel housings in the well-known 30GM design are UV-resistant, have degree of protection (IP 68), and are ideal for installation in harsh industrial environments. A further special feature is the operating temperature range of -20 to +70 °C. This allows the read/write heads to be operated outdoors and in the vicinity of cold or heat sources without any problems. This design is available in both the LF and HF frequency ranges according to the installation location of the associated tags, the required detection range, and any systems already in use. This is one example of how Pepperl+Fuchs is expanding its comprehensive portfolio of components for hazardous areas.
