CCS - MV Bluefin 2017 V01 Radon

Project Overview: A range of solutions will be required to reach globally agreed emissions reductions targets for carbon dioxide (CO2). Carbon capture and storage (CCS) is part of the suite of technologies that will contribute to lowering atmospheric emissions of CO2 from Australia's energy system. There are a wide variety of technologies at various stages of technical and commercial readiness, with more development underway for cost effective CO2 capture and storage. Our research will provide new knowledge to inform cost-efficient measurement, monitoring and verification (MMV) of the environment of CCS projects in coastal waters. --o-- A Durridge model RAD7 radon sensor, coupled to a liquicel membrare contactor equilibrator, was installed in the carbon team’s container and measured seawater from the ship’s auxiliary seawater pump for the duration of the voyage.
Survey settings: A flow of 2-3.5 litres per minute of seawater was maintained through the membrane contactor’s shell side and the RAD7’s air pump was used to circulate 300-700 SCCM air through the lumen side of the contactor and the detector. Readings were stored every 10 minutes (each reading is an integration of counts from the preceding 10 minute period). Calibration Information: The instrument was calibrated by the manufacturer in 2017.
