Method and arangement for the storage of CO2 dissolved in water and its permanent fixation in geologic formations
摘要
In a process to store and fix carbon atmospheric dioxide in a geological formation with ground water, the carbon dioxide reacts with the calcium minerals in cold. The water is cooled by a surface heat exchanger and then pumped back into geological formation thereby promoting precipitation of stable carbon dioxide. The geological formation selected is one which is more soluble with decreasing temperatures. The formation contains e.g. sulphate minerals e.g. anhydrite or gypsum.
