Summary

Petroleum products are increasingly being produced and consumed worldwide, while environmental impacts are increasing. Despite the precautionary measures, there is the risk of significant oil spills. The chemical composition, the properties of escaping oil and the associated weather-related reactions govern their fate, behavior and impact on marine environments. Oil spills are a cause of great concern due to the long-term significant damage to marine ecosystems. This diploma thesis examines the effectiveness of four dispersants in oil dispersion initially at atmospheric pressure as defined by the EPA protocol and subsequently under pressure conditions of 25, 50, 75, 100 bar, adapting the EPA protocol using a high pressure reactor. The purpose of this investigation is to determine the effectiveness of surfactants in an underwater pressure environment. Based on the results of the efficiency of the oil dispersing substances that will emerge, they will be evaluated for the advantages they present.
