Zustandserkennung in Produktionsanlagen durch Asset‐Management

Recognition of the Condition of Production Plant by Asset Management Effective management of assets in chemical and pharmaceutical production plant requires a knowledge of their technical, processing, and economic condition. In particular, for plant with high demands on availability it is the task of technical management to assure production capability by ongoing determination of the technical condition, prediction of future wear and tear, and resulting maintenance measures. They thus make an important contribution to the overall value added chain. This review discusses asset management systems offering the technical management of production plant extended sources of information and diagnostic tools for determination of the technical condition of production plant. The article mentions the possibilities and the demands placed on such systems which support both plant‐related and control engineering maintenance.     

Measuring the effects of laboratory automation: The power of empirically derived models

Laboratory data systems are automated for a variety of scientific and management reasons. A key part to maintaining these systems is to regularly assess the impact that automation has had on the laboratory and the organization as a whole. Smith Kline Beecham R&D is using a number of different types of measurement, as well as a number of different tools, for measuring how automated laboratory systems are affecting the workflow and information flow in the laboratory. This targeted programme of metrics has increased management confidence in laboratory automation efforts, helped anticipate data processing bottlenecks, and highlighted end-user support needs.     

Use of microelectronics to upgrade process control into production control

Process control in oil extraction and processing is traditionally done by independent control loops and logic (sequence) controls. In the best case, all controls are located in one central control room. The operator’s task is to draw the right conclusions from the process conditions signalled to him, to coordinate, to plan and to keep logsheets. On the basis of this information, he can coordinate between control loops and optimize unit operations. With the application of modern microelectronic-based control systems (integrated control systems), it is possible to present the operator’s information on a higher level (e.g., yield figures and energy consumptions computed from basic data), to do computerized planning operations and updatings, and to retrieve data which are used as an input for accounting systems and management information systems. Underlying principles, means for implementation, as well as benefits (both proven and potential) are described. The available hardware and software packages hardly form any limitations; on the contrary, we must often limit ourselves to optimal use of the available tools and not fall into the trap of “maximal automation.” Our aim is not to automate and control as much as possible, but to use automation as one of the means to process oilseeds and edible oils with the highest possible efficiency.     

Aufgaben der Produktionsleitebene in der chemischen Industrie

The plant management functions in chemical industry . The information flow can be structured by a layer model, comprising the plant management layer, the process control layer, and the field layer. The higher company management layer issues production orders which are detailed at the plant management layer with the aid of a formulation; amounts of materials required, equipment, personnel, and laboratory measurements are assigned as a prerequisite for production. These tasks are described in detail, the flow of information between the adjacent layers indicated, and the layer structure of other business units briefly considered.

Such consideration indicates not only the principal functions of information processing but also the necessary integration of process-oriented information systems such as those relating to formulation, production planning, and operating data processing. Various concepts are currently under discussion for such integration.

Inverse Produktion für nachhaltige Wertstoffkreisläufe – Aktuelle Entwicklungen zur automatisierten Demontage und Entstückung von Elektronikplatinen

At the end of the lifetime of electronic products, many of the valuable substances contained therein are still lost. These products could be selectively disassembled with modern production methods in order to win high-quality sorting fractions. The article presents approaches to these challenges of inverse production and discusses examples of current developments for the automated disassembly of electronic boards. Modern sensor and laser technology plays a key role in measurement and disassembly tasks. A dismantling and sorting line for a piece-by-piece processing of cell phones and printed circuit boards with seven interlinked machines was set up and tested at a recycling plant.     

Is combinatorial chemistry on the right track for drug discovery?

Critical to the effective implementation of high throughput methods of synthesis is the necessity for a significant supporting level of automation. There are a number of critical issues associated with the successful introduction, and supporting role, of automation of small molecule chemical synthesis. Clearly there are needs for automation to increase drug candidate synthesis throughput. Automation of repetitive and laborious tasks associated with the synthesis process can release skilled chemists to apply their talents to the more challenging investigational aspects of developing new synthetic protocols. This provides continuity in the compound supply pipeline and ensures an optimal use of the automated platform for compound production. The very high fidelity of performing repetitive processes that can be managed through automation also removes some of the limitations and errors associated with more fallible human operators. This can include very difficult tasks associated with tracking data, and general information and inventory management. Taken collectively, these attributes associated with automation can lead to greater efficiencies, throughputs and improved allocation of human resources with concomitant reductions in costs associated with current day and future drug discovery. In our library development/synthesis paradigm, we feel that automation support must be invoked early in the process and that this automation support must continue throughout the project.

Automatisierung bei der Raffination von Nahrungsfetten

Automation in the Refining of Edible Oils Automatic process control and regulation are now indispensable items in production plants and auxiliary equipment for the refining of edible oils. Their application is primarily aimed towards reduction of cost of wages, energy and raw materials as well as auxiliary materials, and towards maintenance of constant conditions of processing which ensures uniform and high quality product. In addition to classical instrumentation in individual production sections having independent regulating systems, emphasis is laid these days on centralization and coupling of the, various unit operations. Recent developments in the area of programmed control, microprocessors and minicomputers permit suitable and elegant solution of such tasks. Technically sophisticated signal processing shows distinctly that specific receivers of actual processing data are available to a rather limited extent. A few special developments in this area are discussed. In other cases, suitable combination of easily measurable data can be used for comparison.
