Analysis of an event related to the uncontrolled release of ammonia from a rail tanker

Z. 187

Numerical engineering tools are being more and more frequently applied in supporting decisions responsible for rescue operations in terms of tactics and strategy. This elaboration presents one of the applications of such software in the event of uncontrolled releases of hazardous substances. The adoption of numerical modelling as an element which supports leadership results in the reduction of operating costs and affects its performance. The example used will show the potential of these solutions to people unrelated directly to chemical and ecological rescue. It may become a basis for developing drills, including evacuation drills, for people responsible for their planning and organization in the railway structures.

Evaluation of suitability of existing harmful compounds dispersion models for assessment of land pollution with marine engines' exhaust gases

Pawlak M., Piaseczny L.

Silniki Spalinowe

2007

R. 46, nr SC3

62-71

Among hundreds of models used all over the world for description and estimation of dispersion in the atmosphere of harmful compounds being formed during combustion, the great majority of them are the models used for point land sources of pollutants emission (e.g. smokestacks). There are also models describing dispersion of pollutants from road sources. However, there is title information about modeling the emission and dispersion of marine engines harmful exhaust gases. Therefore, there is a need to develop such models. Authors made an attempt to review some existing and commonly used models, from the point of view of their suitability for description of dispersion of pollutants emitted from marine engines. The results of the analysis are premises for conducting the research aiming at developing the models suitable for assessment of the emission and dispersion of pollutants emitted in exhaust gases by marine engines.
