Social Marginal Abatement Cost of Negative Emissions : Incorporating Externalities into the Private Costs of Carbon Dioxide Removal
The essential role of Carbon Dioxide Removal (CDR) in mitigating further climate warming, alongside substantial emission reductions, is undeniable. However, the actions to remove carbon dioxide are not without consequences, necessitating the integration of external costs into decision-making …

Carbon dioxide transfer in membrane oxygenators and associated membranes
… failure requires that the patient's metabolic carbon dioxide production be eliminated by a membrane oxygenator operated in an extracorporeal blood circuit. In conjunction with peripheral cannulation, the oxygenator should be optimised for CO₂ removal at low blood flow rates of 1.5 ℓ/min or less …

Catalytic membrane reactor-separator for environmental applications.
… selectivity value could be useful in small-scale carbon dioxide removal units for natural gas treatment processes. In addition, H2/N2 selectivity of 1.36 and 2.72 at 1 bar were obtained from macro and meso porous membranes at 25 0C. The selectivity of propylene (C3H6) over N2 was also obtained. …
