The SPARCLING JIP was launched by TOTAL, AIR LIQUIDE, SHELL, GRTgaz & INERIS. The goal of the project was to produce high-quality experimental data on the size distribution and velocities of the LNG droplets using a dual PDA (Phase Doppler Anemometer), following the pressurized release of LNG. One area of particular concern is the potential for rainout and subsequent pool dispersion. The test programme was managed and run by INERIS at their test site at Verneuil-en-Halatte on behalf of the members of the JIP. The paper describes in detail the testing bench and test protocol, as well as the lessons learned from the use of the bench. The occurrence of rainout is then discussed.
