Flexible ozone-generation system adapts to fluctuating conditions

Ozone is increasingly being used to eliminate as many pollutants as possible from wastewater. Ozone breaks down trace substances through oxidation or converts them into smaller molecules. They are then easier for micro-organisms to break down in a post-treatment stage or can be removed by means of absorption. Making ozone generation as cost-effective as possible is not easy, because ozone quantities vary greatly due to the huge fluctuations in wastewater quantities and the composition of trace elements. The Dulcozon OZLa is a new ozone system (photo) that can be fitted with up to 16 ozone-generator modules. The modules can be activated and deactivated as required. The amount of ozone produced can therefore be adapted to fluctuations, for example in a clarification plant where varying volumes of wastewater are treated.

Hall 4.0, Stand B8 — Entex Rust & Mitschke, GmbH, Bochum, Germany


This microreactor is designed for electrochemistry scaleup

This organization has developed a flexible and scaleable microreactor for electrochemical conversions (photo). Parallel arranged electrodes, small distance between the electrodes, and their operation under laminar flow conditions lead to homogeneous and beneficial process conditions overcoming limitations linked to conventional electrosyntheses. The reactor concept, based on a plate-stack design approach, allows not only the operation of one electrochemical cell in various configurations, but also the extension to a larger number of cells for scaleup. Now, this expansion approach has been validated through an application of Kolbe electrolysis increasing the number of cells in the stack up to four. Starting from fatty acids obtainable from biomass, Kolbe electrolysis allows the synthesis of valuable chemicals. Envisioned is a further increase up to 20 cells corresponding to a production capacity of about 3 kg/h of production.

Hall 9.1, Stand A31 — Arkema S.A., Colombes, France


Single-use separators eliminate cleaning requirements

The kytero single-use pharma separator (photo) provides high separation efficiency, simple and safe handling and the elimination of costly cleaning procedures. With its maximized separation efficiency, yields up to 98% and gentle product handling, kytero systems enable new ways for processing cell-culture-based fermentations in pilot plants, laboratories and small-scale biopharmaceutical production facilities. As the systems rely on disk separators, the use of filtration is significantly reduced. The kytero 500 was developed for a capacity of up to 150 L/h and is thus suitable for laboratories and small batches. For scaleup applications, another model will soon become available, says the manufacturer. The gentle feed system preserves the vitality of shear-sensitive products. With the single-use separators, all product-contacting parts are replaced after use, preventing any cross-contamination without the need for cleaning and sterilization. The frictionless drive system provides 100% biocontainment by eliminating the need for seals or mechanical bearings. Setup and changeover time (only 5 to 10 min for preparation) is minimal. No auxiliary equipment, such as water, buffers or tanks, is required. Hall 4.0, Stand G66 — GEA Group, Düsseldorf, Germany


These battery-operated forklifts are now IECEx-certified

Last December, the Ex forklift series, equipped with LiTex batteries (photo), received the IECEx safety certification for safe operation in potentially explosive environments, including in gas (Zone 1) and dust atmospheres (Zone 21). Following the 2018 launch of LiTex — the world’s first lithium-ion battery for use in Ex-protected environments — this new certification is a key prerequisite for Korean Certification (KC), which is required in Asian markets. The explosion-proof LiTex battery can be charged at any time in the ATEX zone, just like a normal Li-ion battery, which increases efficiency and availability of equipment. In the past, users had to leave the explosion-proof room or even the shop floor to charge the battery. As charging usually takes around 8 h, batteries had to be changed during shift operation in order to continue working. This significant loss of time is eliminated by LiTex’s pressurized charger. According to the company, a battery life cycle of at least 5,000 full cycles is guaranteed. Hall 9.1, Stand A59 — Stöcklin Logistik AG, Laufen, Switzerland


An overfill protection valve for underground storage tanks

This company offers a wide range of brass, aluminum and stainless-steel safety valves for use in petrochemicals facilities. The company’s Model 442 overfill protection valve (photo) is designed to prevent the overfill of storage tanks by providing a positive shutoff of product delivery. The shutoff valve is an integral part of the drop tube used for gravity filling. The Model 442 is certified as a two-stage shutoff valve. When the liquid level rises to about 95% of the tank capacity, the valve mechanism is released, closing automatically with the flow. The operator may then stop the filling process and disconnect and drain the delivery hose. As long as the liquid exceeds the 95% level, the valve will close automatically each time delivery is attempted. If the delivery is not stopped and the liquid rises to about 98% of tank capacity, the bypass valve closes completely. No additional liquid can flow into the tank until the level drops below a reset point. Hall 9.0, Stand A30 — Ridart S.r.l., Gazzada Schianno, Italy


This system can be adapted to count tablets or gummy products

The DMC Series is an automatic tablet/capsule counting machine (photo) that can be equipped with special parts and devices and modified to become a counter for gummy products. By replacing the hopper and tray for the gummy, it is possible to count and fill both conventional tablets and gummy products with a single counting machine. The adaptable gummy-exclusive tray features an embossed stainless-steel surface to improve the flowability of the gummy product, and a special agitator installed in the hopper helps to loosen any clumped gummy products and separate them one by one. When compared to a typical checkweighing system, a designated counting machine can increase productivity because loss rate is reduced. Hall 3.1, Stand G69 — Countec Ltd., Gyeonggi-Do, South Korea


Crossflow filters ensure high product quality and yield

Whether the targeted products are solid or liquid, the Krauss-Maffei DCF increases yield and product quality. The filters offer extremely high yields and can process highly concentrated suspensions up to a viscosity of 7,000 mPa·s. Product quality is assured due to the DCF’s single-pass filtration concept, short residence times and the elimination of gas contact. Higher permeate flux means that a smaller installed equipment footprint is required. Hall 12.0, Stand C19 — Andritz Separation GmbH, Graz, Austria


Continuous casting for membranes, films and more

This company offers continuous film-casting systems (photo) for the production of membranes, separators, ceramic tapes and optical films. The systems use a stainless-steel belt to transport a layer of liquid product through a series of carefully controlled sections. This involves heat and mass transfer in the evaporation process or a controlled phase-separation process in a precipitation section. Once these processes have been completed, the solid formed or transformed product is removed from the belt. At this stage, the product will be either in final or intermediate form; the latter requiring further processing, such as post-drying, leaching or stretching. Key benefits include ultra-efficient continuous production, the ability to cast very thin films to fine tolerances and producing high-quality microporous membranes. A pilot film-casting line with a Venturi dryer module and a conventional impingement-dryer section is available for customer trials at the company’s productivity center in Fellbach, Germany. The unit features a winding and unwinding unit and is capable of handling water- or solvent-based casting solutions. Hall 4.0, Stand D4 — IPCO Germany GmbH, Fellbach, Germany

Hall 9.1, Stand B3 — Pörner Ingenieurgesellschaft GmbH, Vienna, Austria


Dry products gently and reliably at low temperatures

This company has developed the Airgenex heat-pump-based condensation drying system (photo), which combines seemingly contradictory features, such as short drying times and low temperatures. Upon completion of the drying cycle, the products are completely dry or dehumidified to the desired dry matter content, as specified. Drying takes place at a defined temperature between 20 and 90° C, which is beneficial to both personnel and products. These dryers use a closed air system. As the constancy of parameters is safely ensured, the process is independent of any environmental conditions. With minor modifications, the system may also be used for cooling to become a combined drying-cooling type if desired or required by the specific process. Additional non-compressed air blowing to remove sizeable amounts of water is also offered. The dryers may be used for both batch and continuous processes. Hall 3.1, Stand H48 — Harter GmbH, Stiefenhofen, Germany


This digital twin platform simplifies data transfer and integration for retrofit projects

This company’s EB Alliance concept supports digital-twin integration with seamless data exchange between operators and suppliers who have each set up their own environments within the Engineering Base platform. EB Alliance also enables outsourcing and consistent reintegration of a digital twin of rebuild projects within an operating plant, no matter how complex. According to the company, EB Alliance allows all data to be mapped to the configuration state of the recipient, so that errors or misunderstandings do not occur in the first place. Additionally, the ability to hand over the digital twin of a plant section that is to be retrofit or expanded, as well as integrating it consistently into the new as-built state once the work is done, can also significantly speed up retrofit and maintenance projects.
