Designing reliable safety systems requires expert knowledge and robust process models to prevent injuries to people and damage to equipment. In a recent project at the SINTEF Tiller test facility in Norway, a large-scale vessel was installed to act as a gas reservoir for the gas mixtures to be handled. In the preparations for tests involving mixtures of CO2 with N2, CH4, and C2 and C3 components at high pressure and elevated temperatures, the pressure relief system was assessed and designed before the tests were commenced. At a certain point during the experiments, the operators had to activate the blowdown function of the vessel due to a gas leak from a flange connecting external equipment to the vessel.
In this webinar, researchers from Aker Solutions, SLB Capturi and SINTEF will present results of the analysis that was conducted after the incident. This includes an investigation on the unexpected long blowdown time as well as simulations of the harmful gas cloud that was spread out on the ground and on the heat exchange of the gas inside the vessel. These simulations can help to mitigate future similar incidents.
