Open-loop stripping analysis (also referred to as dynamic headspace) is a very flexible and robust technology for online monitoring of volatile organic compounds in wastewater or coolant. However, the quality and reliability of the analytical results depend strongly on the temperature during the stripping process. Hence, the careful and constant heating of the liquid phase inside the stripping column is a critical parameter. In addition, this stripping at high temperatures extends the spectrum of traceable organics to less volatile and more polar compounds with detection limits down to the ppm-level. This paper presents a novel and promising approach for fast, efficient, and constant heating by the direct injection of process steam into the strip medium. The performance of the system is demonstrated for temperatures up to 75 °C and traces of various hydrocarbons in water (e.g., tetrahydrofuran, methanol, 1-propanol, n-butanol, ethylbenzene).

Zusammenfassung Softsensoren bieten eine attraktive Option, schwer messbare Prozessinformationen indirekt aus konventionellen Messgrößen (Druck, Temperatur und Durchfluss) online zu berechnen. Durch Kombination mit Prozessanalysentechnik, die spezifische physiko-chemische Informationen liefert, lässt sich der Anwendungsbereich von Softsensoren und Prozessanalytik deutlich erweitern. Mit der Online-Berechnung einer Katalysatoraktivität und eines Verkokungsgrades wird der Einsatz von Softsensoren in der industriellen Praxis bei BASF demonstriert. Das zukünftige Potential für Softsensoren in der Prozessanalytik wird anhand der überarbeiteten Technologie-Roadmap “Prozesssensoren 2015+” diskutiert.
