The commercial deployment of carbon capture and storage technology
One of the most significant impediments to a carbon dioxide capture and storage industry is not technical but legal-managing liabilities associated with the long-term geologic storage of carbon dioxide in reservoirs, particularly deep saline. There is no dedicated regulatory regime in place at either the federal or state level for capture and ...

Feasibility of using ionic liquids for carbon dioxide capture
Ionic liquids (ILs) are organic salts that are liquids in their pure state at ambient conditions. They are frequently referred to as "environmentally benign" due to their immeasurably low vapour pressure. In addition to their more widely studied capabilities as solvents for reactions, several ionic liquids also show potential in other environmentally conscious applications, such as in the capture ...

Carbon dioxide capture and storage: Priorities for development
Oil, coal and natural gas will remain the world’s dominant sources of energy over the next decades, resulting in unsustainable levels of carbon dioxide emissions. This trend can be reversed only via a near revolution in the way we produce, transform and consume energy. Concerted global action is urgently needed to increase investment in energy technology solutions. Carbon dioxide capture and ...

Feasibility Study of Using Brine for Carbon Dioxide Capture
ABSTRACT A laboratory-scale reactor was developed to evaluate the capture of carbon dioxide (CO2) from a gas into a liquid as an approach to control greenhouse gases emitted from fixed sources. CO2 at 5–50% concentrations was passed through a gas-exchange membrane and transferred into liquid media—tap water or simulated brine. When using water, capture efficiencies exceeded 50% and ...

Carbon dioxide capture: an assessment of plausible ranges
The projections of energy related carbon dioxide (CO2) emissions in the Special Report on Emission Scenarios (SRES) of the Intergovernmental Panel on Climate Change (IPCC) serve as point of departure for an assessment of plausible ranges of CO2 emissions that could be avoided through CO2 capture and storage measures. Scenario and time dependent, sector and fuel specific capture factors are ...

Carbon dioxide ocean and ground storage as a method of climate change mitigation
Global warming-induced climate change is one of the significant civilisation threats of the modern times. Human-induced enhanced global warming, via the greenhouse effect resulting from high carbon dioxide emissions, poses a substantial danger to the environment we live in. Consequences of global warming can be devastating for the present, but mainly for the future generations. This paper reviews ...

Bio-desulfurization and denitrification by anaerobic-anoxic process for the treatment of wastewater from flue gas washing
For amine-based carbon dioxide capture, nitrogen oxides and sulfur oxides were the main pollutants that had a negative effect on the regeneration of solvent. Before carbon dioxide capture, the sulfur oxides in flue gas should be removed by the method of calcium salt, and then washed by alkaline solution to eliminate the residual nitrogen oxides and sulfur oxides. The washing wastewater ...

Capture of carbon dioxide by solid amine sorbents
The reaction of tetraethylorthrosilcate (TEOS) with y-aminopropyltriethoxysilane (APTS) has produced stable solid amine sorbents for the capture of carbon dioxide. The resulting amine-enriched silicon sorbent (SBA-15) has been proven to be competitive with existing environmental CO2 controlled life sorbents based on the immobilised amine technology. XPS analysis has indicated that the amine ...

Liability and financial responsibility frameworks for carbon capture and sequestration
Carbon dioxide capture and sequestration (CCS) is an important option for reducing CO2 emissions from human activities. There is growing interest in CCS as renewable energy and energy efficiency alone are unlikely to deliver the emission reductions necessary to stabilize atmospheric concentrations of greenhouse gases by mid-century.1 CCS involves capturing CO2 generated from fossil fuel ...

The CO2 and SO2 capture capability of two Greek limestones during repeated thermal cycles
In the present study, two Greek limestones from the Megalopolis and Florina areas were used to capture CO2 and SO2. The regeneration ability and decay of the limestone samples were investigated through sorption-calcination cycles in a thermogravimetric analyser operated at ambient pressure. The effects of the sorption time (3, 8 and 30 min), reaction temperature (750°C and 850°C) and particle ...
