T1 - Massenabbrandraten organischer Peroxide unter besonderer Berücksichtigung der thermischen Stabilität N2 - Die Flüssigkeitstemperatur Temperatur in der flüssigen Phase unmittelbar im Grenzbereich zur Gasphase während eines Abbrandes organischer Peroxide überschreitet die Onset-Temperatur der beginnenden exothermen Zersetzungsreaktion des Peroxids, so dass diese zu berücksichtigen ist. Für die Peroxide Di-tert-butyl-Peroxid (DTBP) und tert-butyl-peroxybenzoat (TBPB) muss daher bei der Berechnung des Wärmerückstromes ein zusätzlicher Term für die Zersetzung in der Flüssigkeit additiv ergänzt werden. Der Umsatz der Zersetzungsreaktion wird unter den Bedingungen eines CSTR modelliert und erfolgt auf Basis einer Reaktionskinetik 1. Ordnung. Es kann gezeigt werden, dass der Wärmestrom in einem DTBP-Poolfeuer ≈ 40 % und einem TBPB-Poolfeuer ≈ 100 % des Wärmerückstromes durch Wärmestrahlung entspricht. Durch Q-Punkt-d können die vergleichsweise hohen Massenabbrandraten und die relative Unabhängigkeit der Massenabbrandraten vom Pooldurchmesser erklärt werden. Über eine Energiebilanz wird ein Modell basierend auf physikalischen Parametern entwickelt, das die Massenabbrandraten großer Poolfeuer, in sehr guter Übereinstimmung mit den experimentellen Ergebnissen, vorhersagt.

The incident has left many safety issues behind which must be repeatedly addressed. Unfortunately, the lessons taught by previous similar events are just not understood carefully. It reveals that the proper safety measures for such facilities were either underestimated or were not accounted seriously. Consequently, the resulting overpressures from explosion and the subsequent thermal radiation from tank fires have once again proved to be disastrous to both mankind and infrastructure. This article highlights the aftermaths of Amuay incident and addresses the challenges put forward by it. Furthermore, a comparative study is performed between such incidents to analyze the similarities and how they could have been avoided.

The model is independent of type and burning rate of the spilled/dispersed fuel and considers only overflow Reynolds number (Re) to characterise the spill/dispersion behaviour. Additional simulations are performed for LNG (Liquified Natural Gas) dispersion and it is found that the model can be used for different fuels within a defined range of Re. Different scenarios with Re = 100 to 3 × 105 are investigated covering a wide range of mass flow rates, opening sizes and viscosities. Depending on Lower Flammability Limits (LFL) of the fuels spill/dispersion (vapour cloud) diameters (DCFD) and heights (hCFD) are predicted. A generalised correlation between DCFD and Re is established to predict the dispersion occurring at varying scales. The model is validated by: (1) conducting an extensive grid independent study; (2) comparing the results with the existing analytical methods and (3) comparing against the standard field test data on LNG dispersions.
