Consequence Study of Pressurized CO₂ Release Containing Impurities with Obstacles

Abstract:

A rupture or puncture of a carbon dioxide (CO₂) pipeline will result in a release of dense CO₂ gas cloud mixed with toxic impurities such as hydrogen sulfide (H₂S) to the ambience. This paper has proposed an approach for developing an accurate consequence model for CO₂ release containing H₂S in order to demonstrate a safe layout and other safeguards. Thus, a validated code using computational fluid dynamics (CFD) was applied to predict time-varying concentrations of CO₂ and H₂S at a point of downwind release area. Then overall fatality rate due to both CO₂ and H₂S has been estimated at this point. Results indicate that this is a suitable method for assessing the consequences of the release of CO₂ via pipeline leakage.
