Capture: CO2 is separated from other gases produced by industrial facilities or power plants. This can be done using various methods such as pre-combustion capture, post-combustion capture, and oxy-fuel combustion. Transportation: The captured CO2 is then compressed and transported to a storage site. Transportation methods typically include pipelines, but ships, rail, and trucks can also be used.
Storage: Finally, the CO2 is injected into deep underground geological formations, such as depleted oil and gas fields or saline aquifers, where it is safely stored and prevented from re-entering the atmosphere. 3. Current all india whatsapp number list Technologies in Carbon Capture Chemical Absorption: This is the most common method, in which CO2 is absorbed by a solvent (usually an amine-based solution) and then released through a regeneration process. This method is widely used in post-combustion capture.
Physical Adsorption: In this method, CO2 is adsorbed on the surface of a solid material and then desorbed under various conditions. Zeolites and activated carbon are commonly used adsorbents. Membrane separation: Membranes selectively allow CO2 to pass through while blocking other gases. This technology is still being developed but has the potential for lower energy consumption compared to traditional methods.
The process involves three main steps:
