Abstract

Blowdown tests of a 2m3 CO2 vessel were performed at the Ineris facilities. Blowdown can be performed either at the top of the vessel for the gas phase, or at the bottom for the liquid phase.

The measured parameters during depressurization include: i) the pressure; ii) the fluid temperature at different heights inside the sphere; iii) the wall temperature at different heights; iv) the mass
of the fluid in the vessel.

To benchmark the experiments, LedaFlow software that can calculate the temperature at different heights within the liquid phase, the gas phase and along the wall was used. The aim of this benchmarking was to assess thermodynamic and transport models available in LedaFlow.
Deviations between calculated and experimental temperatures increase with depressurization time and reach values of 7°C when all the liquid has escaped from the vessel (during liquid blowdown), or when we reach dry ice domain (during gas blowdown). Deviations in pressure remain small throughout the tests, less than 1bar.

Keywords: CO2 vessel depressurization; LedaFlow software; gas phase blowdown; liquid phase blowdown
