Controlled release of water into oxygen scavenger
The invention provides an article for oxygen absorption comprising a container containing a water-soluble ion source, an water activated oxygen scavenger, and a rupturable canister of hydrated polymer. The invention provides in another embodiment a method for providing timed or controlled oxygen absorption comprising providing an article for oxygen absorption comprising a container containing a water-soluble ion source, an water activated oxygen scavenger, and a rupturable canister of hydrated polymer, rupturing the canister, whereby the hydrated polymer and water-soluble ion source come in contact and release water, and the water as it is released activates the oxygen scavenger.
Abstract To quantify the risk and impact of CO2 seepage to the marine ecosystem, the Quantifying and Monitoring Potential Ecosystem Impacts of Geological Carbon Storage project is now undergoing in a bay in Scotland. In advance of the field experiment of this project, we conducted the numerical simulation of CO2 seepage. From this numerical study, we predicted how CO2 behave in the bay and how the condition of the sea changes.
