Description
Summary:The recent eruption of the Icelandic volcano has focused the worldwide attention on volcanic ash effects for the population, road, rail and air traffic and production activities. This paper aims to study of technological (industrial) accidental scenarios triggered by ash fallout and, more specifically, to define and quantify the potential damage on filtration systems. Malfunctions due to the filter clogging and service interruptions caused by the rupture of the filtering surface have been analysed in order to define the vulnerability of the equipment to such damages. Results are given in terms of threshold values of deposit on the filtering surface and exceedance probability curves of ash concentrations and the duration of the ash emission. This data can be easily implemented in the standard risk assessment with the aim to include the estimation of Natural-Technological (Na-Tech) hazards.
