A model of health risk evaluation
A model of health risk evaluation.

Serious explosion accidents have occurred in EU countries that have involved the bulk storage of display fireworks. Currently, there is no means of estimating the hazards posed by such storage and the UN transport classification scheme is all that ca

The aim of the eRisk project is to develop a new concept for networking different risk management organisations and services. The eRisk concept is based on the Finnish Risk Management Toolkit (www.pk-rh.com). The new concept will be a modular, custom

This experimental/ theoretical/numerical project aims at revealing the physical-chemical mechanisms of explosion, and at deriving innovative methods for explosion protection. Both LES and VLES modelling strategies, with appropriate models for combust

Generalized criteria for assessing thermal stability of discontinuous reactors? Doctoral Thesis
The thesis has been undertaken with the main purpose of developing intrinsic criterion that would allow the prevention of thermal runaway for any process carried out in discontinuous reactors (batch and semi-batch processes). Intrinsic criteria, b

Methodologies for thermal risk analysis of discontinuous chemical processes (Metodologies per l?an?lisi del risc t?rmic de processos qu?mic discontinues) ? Doctoral Thesis
The project presents a comparative analysis of methodologies to realise studies on thermal security of chemical reactions, in discontinuous mode, currently used in several research centres. Furthermore, the project presents an analysis of its use bas

Process industry is challenged to produce higher product yields at lower costs and less waste while maintaining safety. Sustainable growth requires more partialoxidation of hydrocarbons and biomass. Such developments will increase explosion risk. Ris
