An investigation of gas phase explosion propagation limits on ethene mixtures N2 - A method for the determination of safety properties for micro reactors and micro structured components is presented. Micro structured reactors are not inherently safe but the range of safe operating conditions of micro reactors are extended since the explosion region is reduced. The λ/3 rule was demonstrated to be applicable to micro scale tubes for stoichiometric mixtures of ethane–oxygen and ethane–nitrous oxide. Furthermore first results from an investigation concerning detonation propagation through a micro reactor of non-ideal geometry are shown. Initial pressure investigated is ranging from low pressure up to 100 kPa.

T1 - Explosion initiation, propagation, and suppression inside a micro structured reactor N2 - The present contribution reports on specific aspects of safety engineering in heterogeneously catalysed oxidation reactions. Results for ethene-oxygen-mixtures in a continuous-flow micro reactor are reported related to the safety issues of the ethylene oxide process. Initial pressure is ranging from below 1 bar up to 10 bar at initial temperatures ranging from room temperature up to 673 K. Micro structured reactors offer an extended range of operating conditions. The key issue to be discussed in the present contribution is how to safely operate a micro reactor at conditions in conventional devices to be characterised as inside the explosion region. Within certain limits suppression of explosion inside a micro reactor can be achieved. This holds true for chain reactions as well as runaway reactions. Nevertheless it is not possible to safely operate micro structured reactors at any condition. Therefore, explosion propagation through a Micro structured reactor and initiation of gas phase explosions by hot spots inside the reactor were investigated. The investigation methods applied are subject to actual standardization.

T1 - Sicherheitstechnische Untersuchungen zum Betrieb von Mikroreaktoren im Explosionsbereich N2 - Es wird eine Methode zur sicherheitstechnischen Untersuchung von Mikroreaktoren und mikrostrukturierten Komponenten, die im Explosionsbereich betrieben werden sollen, vorgestellt. Mikrostrukturierte Reaktoren sind nicht inhärent sicher, wenngleich der Bereich der sicheren Betriebsbedingungen gegenüber konventionellen Reaktoren erweitert ist. Der Explosionsbereich kann durch die Mikrostrukturen eingeengt werden. Am Beispiel von Ethylen/Sauerstoff-Gemischen und Ethylen/N2O-Gemischen wird hinsichtlich der Ausbreitung von Detonationen durch Kapillarrohre gezeigt, dass die sogenannte λ/3-Regel angewandt werden kann. Darüber hinaus werden erste Ergebnisse der Untersuchung der Ausbreitung von Explosionen durch einen Mikroreaktor mit rechteckigem Strömungskanal vorgestellt.
