Automation & Control
Fig. 1. The waste water treatment plant has a comprehensive control solution.
Every aspect of plant automation depends on a variety of different controllers. The latest releases tackle every aspect of plant operations, including aggressive conditions. Sean Ottewell reports.
Jeder Bereich der Anlagenautomatisierung wird von einer Vielzahl verschiedener Steuergeräte reguliert. Die neuesten Modelle werden mit allen Bereichen des Anlagenbetriebs fertig, auch mit aggressiven Bedingungen. Sean Ottewell berichtet.
Chaque aspect de l’automatisation d’une usine dépend d’une variété d’appareils de contrôle différents. Les dernières nouveautés prennent en compte chaque aspect de l’exploitation de l’usine y compris les conditions agressives. Selon Sean Ottewell.

ontrolCare Field-based Control System (FCS) from Endress + Hauser is a combination of software and hardware components based on open standards, the purpose
of which is to connect Endress+Hauser devices to process control, operating and maintenance systems. It provides quick and easy system integration and ensures that the benefits of fieldbus technology are available at all levels of the control hierachy. ControlCare components can be used to supplement a third-party system, or be used as a control system within its own right. One of the company’s recent successes is in Italy,
where ControlCare is helping a solvent recycling company to meet its process and regulatory needs. La Vichimica, located in Novara, Northern
Italy, specialises in the reprocessing of solvents from different process industries, notably pharmaceuticals. During reprocessing, these solvents are separated from dangerous by-products.
Every day, tankers carrying contaminated solvents arrive at the works. The contents of the tankers are transferred into the storage tanks for the columns. At the start of the process the solvent is slowly heated. In the subsequent re-circulation phase, the solvent vapour is continually pumped through the columns until the required degree of purity is attained. The program’s configuration, which is implemented in both field controller and devices such as the valves, control the process. After completion of the process, the purified solvent can be reused and the residues are sent for disposal. The two columns that are controlled by ControlCare can be connected together to form a super-column, increasing the range of applications for which the product can be used. The plant was equipped exclusively with
Endress+Hauser fieldbus devices, and the contract also included: project management; basic, detailed and realisation engineering; and a complete
