Pipeline Transportation of Carbon Dioxide Containing Impurities
12 Atmospheric Dispersion of CO2 Containing Impurities
Download citation file:
Dispersion modeling of CO2 release scenarios needs to be included as part of a quantitative risk analysis when designing or operating CO2 pipelines, as discussed in Chapter 11. Analysis of release conditions, and subsequent dispersion, can help evaluate factors that increase the risk of a loss due to physical or toxicological impacts (e.g., emergency shutdown valve spacing). Simulation of a CO2 release presents new challenges when compared to simulation of natural gas releases. One of these challenges is the dispersion characteristics of a CO2 pipeline release to atmosphere. Although a CO2 release does not pose an explosion risk as with...
