Carbon dioxide along WOCE line A14: Water masses characterization and anthropogenic entry

Ocean-atmosphere partitioning of anthropogenic carbon dioxide on centennial timescales

[1] A theory for the ocean-atmosphere partitioning of anthropogenic carbon dioxide on centennial timescales is presented. The partial pressure of atmospheric CO2 (PCO2) is related to the external CO2 input (DSC) at air-sea equilibrium by: PCO2 = 280 ppm exp(DSC/[IA + IO/R]), where IA, IO, and R are the pre-industrial values of the atmospheric CO2 inventory, the oceanic dissolved inorganic carbo...

Rapid carbon mineralization for permanent disposal of anthropogenic carbon dioxide emissions.

Carbon capture and storage (CCS) provides a solution toward decarbonization of the global economy. The success of this solution depends on the ability to safely and permanently store CO2 This study demonstrates for the first time the permanent disposal of CO2 as environmentally benign carbonate minerals in basaltic rocks. We find that over 95% of the CO2 injected into the CarbFix site in Icelan...

Fabrication and Characterization of Polyetherimide Hollow Fiber Membrane Contactor for Carbon Dioxide Stripping from Monoethanolamine Solution

In this research, process asymmetric polyetherimide hollow fiber membranes using ethanol (0, 2 and 4 wt%) as non-solvent additive in the polymer dope via phase inversion method were fabricated. Aqueous solution of 1-methyl-2-pyrrolidine (NMP) (90%) was applied as a bore fluid to avoid inner skin layer formation and water was used as the external coagulant. The morphology of fabricated membranes...
