Evaluation of CO2 Dilution in Ocean sequestration

In this article, we performed numerical simulations to investigate dissolution and dilution processes of releasing CO₂ in the ocean with the advanced CO₂ dilution technology, in which enhancement of horizontal dilution of released CO₂ can be expected by using arrayed cylinders behind the CO₂ releasing pipe. Numerical analysis in which turbulent properties based on our experimental investigations were taken into account showed that no distinct increase of DeltapCO₂ was observed 120min later after liquid CO₂ release. It was also shown that less biological impact with the proposed CO₂ dilution technology was expected because increase of DeltapCO₂ was suppressed.
