Post-Combustion Carbon Capture & Air Pollution

Current global warming scenario is an after effect of CO₂ emission from fossil fuel combustion and human activity. Severe GreenHouse Gas (GHG) emissions have ushered in the need for critical thinking and action to reduce GHG emissions and to protect the environment for future generations.

There is an immediate need for sustainable and cost effective technologies to capture CO₂ from flue gases and convert it to a useful energy source. We need a solution that can minimize the amount of amine consumption and still provide a net zero greenhouse gas emission.

GAS LAB has developed some of India's pioneering CO₂ capture systems and continues to have an active research and development programme in this area.

One of the most significant greenhouse gases is carbon dioxide (CO₂). The combustion of fossil fuels is the most significant source of anthropogenic CO₂ that has contributed to the rise in atmospheric concentrations since the industrial revolution. These emissions are predicted to contribute significantly to global climate change, which is already creating serious effects for ecosystems and humans. These emissions should be limited in this situation in order to minimize climate change. Global nations are already making efforts to limit CO₂ emissions and move towards NET ZERO emissions. However, there is a need for cost effective, sustainable technologies to capture CO₂, if we have to meet the challenge of climate change.

Carbon Capture and Storage (CCS) is a technological concept that aims to reduce CO₂ emissions into the atmosphere as a result of various industrial processes, particularly the use of fossil fuels (primarily coal and natural gas) in power generation, as well as combustion and process-related emissions in industrial sectors.

Another point of view that is largely discussed is, the implementation of CO₂ capture at power plants and major industrial sources may have an impact on local and transboundary air pollution, specifically the production of critical atmospheric emissions such as SO2, NOX, NH3, Volatile Organic Compounds (VOC), and Particulate Matter (PM2.5 and PM10). The literature suggests that using CCS can have both beneficial and negative effects on overall air quality. The scientific evidence for both points of view is growing rapidly.

As governments establish GHG mitigation action plans, the possible connection between CO₂ collection and air quality targets is critical. External and unintended trade-offs in air quality, as well as co-benefits of CCS implementation, should be understood before adopting this technology on a broad scale.

Several technical approaches for CO₂ separation and capture are now being studied, including carbon capture from post-combustion, pre-combustion, oxy-combustion, chemical looping combustion (CLC), and ambient air.

Post-combustion capture involves separating CO₂ from flue gases that have a low CO₂ partial pressure (0.03–0.2 bar) and/or a low CO₂ concentration (3–20 percent). Carbon capture from some industrial sources, such as cement manufacturing and stainless steel factories, can also be classified as post-combustion capture, despite the fact that the CO₂ concentration in those industrial processes is higher than that of a typical flue gas from post-combustion power plants. The chemical absorption-based aqueous amine solution, such as monoethanolamine (MEA) solution, is the commercially available post-combustion capture process. For existing coal-fired power plants, post-combustion capture is seen as a more practical option.
