EDL Anlagenbau Gesellschaft mbH (EDL), the technology and engineering provider based in Leipzig, Germany, sold a license for its two-stage extraction technology to the Middle East in the 4th quarter of 2018. With this technology process oils are produced in an efficient and eco-friendly way. These oils play, for example, an important role as high-quality tender oils for the production of automobile tires.

The new solvent extraction plant for the production of eco-friendly, high-quality process oils (TDAE, Treated Distillate Aromatic Extract) based on the EDL license allows customers to meet the latest environmental and quality requirements and to expand their product portfolio. The new solvent extraction plant will be designed under consideration of new resource-saving technologies.

As part of the licensing, EDL carries out the required laboratory tests and prepares the PDP (Process Design Package) for the plant and the FEED (Front End Engineering Design) for the extractor section.

EDL Test Facilities

The required process parameters and the optimum process conditions are determined in EDL’s own test facilities based on customer and product requirements as well as the hydraulic data of extractor internals. This allows a safe design of the plant for the entire range of feedstock available at the customer.

High-quality products in two extraction steps

The basic principle of EDL’s technology to obtain high-quality base and process oils from vacuum distillates (lube cuts) and deasphalted oil (DAO) is a two-stage extraction process.

As a first step of extraction the aromatic compounds are removed as so called DAE (Distillate Aromatic Extract) or RAE (Residual Aromatic Extract). NMP (or furfural) is used as solvent. At the same time aromatic-rich oils are obtained that can be used to produce high-quality base oils.

In a second extraction stage using a proprietary solvent mixture, DAE and RAE are transformed into high-quality process oils such as Treated Distillate Aromatic Extract (TDAE) and Treated Residual Aromatic Extract (TRAE) having a low level of polycyclic aromatic hydrocarbons (PCA).

Eco-friendly atoxic process oils for the tire industry

DAE and RAE are required as tender oils to produce rubber products, such as tires, hoses, belts, cable insulation, floor coverings and shoe soles. Due to the high percentage of PCA being carcinogenic, mutagenic and reprotoxic DAE and RAE are no longer used today. With further processing of DAE and TAE to TDAE and TRAE resp. in the second extraction stage the limit value for PCA clearly falls below 3 percent by mass as required by European Directive 2005/69/EC without impairing the excellent properties as tender oil. Thus, a decisive contribution to the protection of human beings and the environment is made.

In addition to solvent extraction EDL also grants licenses for other technologies to produce base oils, process oils, waxes and other high-quality specialty products, such as Dewaxing / Deoiling, Micronization, Aromex or the solvent deasphalting process SDA Plus.

Michell Instruments Chilled Mirror Hygrometer Range S8000 Industry Process Technology

In many processes moisture is a critical factor that needs to be monitored, and controlled. Chilled mirror is the technology of choice for humidity measurements to national standards in laboratories worldwide.

Chilled mirror has the highest attainable accuracy of any dew-point measurement technology, and provides excellent repeatability over a wide measurement range. It is a proven, well established and reliable measurement technique: the temperature at which condensation forms on a surface is measured directly, so there are no calculated variables that could change over time. This means chilled mirror does not suffer from drift or hysteresis.

At this year’s Interphex as well as at Powtech Coperion K-Tron will display the next generation of its highly accurate, gravimetric K3-PH feeders for the pharmaceutical industry. These modular feeders have been specially designed to meet the growing demands of continuous processing. Thanks to the use of a smaller D4 platform scale incorporating the patented and highly accurate Smart Force Transducer (SFT) weighing technology, they require significantly less floor space compared to previous models. Depending on the process and requirements, several feeders can be grouped into a cluster, for example for continuous processes such as direct compression (CDC), extrusion, wet and dry granulation, and continuous coating as well as traditional batch processes.

Easy handling and better product quality

The modular design of this innovative feeder line simplifies cleaning and reduces changeover times. The “Quick Change” design, whereby the feeder bowl can be quickly decoupled from the feeder drive, also enables simple and fast product changes. By simply releasing two clamps, the used feeding unit can be removed and replaced with a clean one.

The three available Coperion K-Tron feeder types QT20, QT35 and QS60 (twin and single screw) can be used with the same scale and drive units. They are interchangeable, depending on the product to be fed, the required feed rates and the necessary scale resolution. For an optimal Wet-In-Place (WIP) result, every unit has an integral two degree pitch facilitating maximum drainage during the cleaning process. In addition, the feeder bowls and hoppers feature a new improved seal design for optimal product containment. The complete line of equipment is engineered to meet the rigid requirements of the pharmaceutical industry, including strict adherence to cGMP guidelines and standards as well as the use of FDA approved materials of construction. Initial industry reactions to the design include very positive comments on the use of a single gearbox for the complete speed ranges of all feeder models.

High-accuracy weighing with patented SFT technology

The new D4 platform scale features the same state-of-the-art sanitary design of the established Coperion K-Tron D5 scale. Smooth, crevice free surfaces prevent deposit of dust and product residue and enable easy cleaning. The redesign of the scale from a round design to a trapezoid design features a much smaller footprint and facilitates an optimized multi-feeder arrangement. This is especially useful in areas with limited space, where multiple ingredients must be fed into one process inlet. At the heart of the new D4 scale, Coperion K-Tron’s patented SFT single wire weighing technology provides a highly accurate weight signal with a resolution of 1:4,000,000 in 80 ms. The electronics include linearization, temperature compensation and a digital low-pass filter to reduce the effect of plant vibration. The 100% digital design eliminates the need for calibration.

In future, it will be possible for existing motors operating in the field to be retrofitted with the Simotics Connect 400 connectivity module from Siemens. This will allow size AH100 to AH450 low-voltage motors operated directly from the mains to transmit operating data straight to the cloud-based Sidrive IQ Fleet App without the need for any structural modifications. Regular data analysis allows plant operators to quickly and efficiently oversee the operational status of their drive systems and plan a servicing schedule based on actual requirement. This not only improves efficiency, but also optimizes serviceability and extends service life. Typical applications requiring monitored low-voltage motors include pumps, fans and compressors.

At this year’s Hannover Messe; Siemens will be using a brownfield application to demonstrate how plant availability can be optimized in future using Simotics Connect 400. The connectivity module comes with all the sensors required for capturing motor vibration or temperature-related data, a Wlan communication module and a battery to enable independent operation. The module processes and saves the operating data, and sends it to the Sidrive IQ Fleet App for cloud-based analysis. Special algorithms use the data to generate meaningful key performance indicators (KPIs) which describe the status of the motors, and are used to determine any concrete need for action. If required, the modules can be retrofitted to legacy motors to improve reliability and availability and boost performance.

Sidrive IQ: IoT digitalization portfolio for drive systems

Sidrive IQ is an essential component of the Siemens digitalization portfolio which opens up wide-ranging scope for IoT (Internet of Things) optimization across the entire drive train – from production through to servicing. Sidrive IQ MindSphere offers a variety of different applications and customized services. Sidrive IQ Fleet is used predominantly in process industry applications, and Analyze MyDrives is designed in the main for the discrete manufacturing industry. Both applications enable the visualization, analysis and monitoring of drive data.

The Sidrive IQ application Analyze MyDrives additionally allows the operating status of Sinamics low-voltage converters to be reliably and conveniently monitored, while gathering and analyzing their operating data. By continuously monitoring power consumption, torque and frequency and also measuring energy flows, users can identify any optimization and maintenance requirement and so initiate any necessary actions in good time. This reduces the need for fixed-interval maintenance, making for greater machine productivity and allowing energy saving potential to be identified.

As a result, plant operators benefit from improved plant availability. A range of connectivity modules for low-voltage and medium-voltage converters as well as low-voltage and high-voltage motors are available from Siemens for linking drive systems to the cloud.
