“…One of the main challenges of this method is to produce oxygen with high purity at a reasonable expense. Wu et al [90] summarized different work done on the separation process of oxygen from the air for use in oxy fuel combustion. They argue that membrane methods are more economical and simpler compared to the cryogenic method.…”

With rapid growth in global demand for energy, the emission of CO2 is increasing due to the use of fossil fuels in power plants. Effective strategies are required to decrease the industrial emissions to meet the climate change target set at 21st Conference of the Parties (COP 21). Carbon capture and storage have been recognized as the most useful methods to reduce the CO2 emissions while using fossil fuels in power generation. This work reviews different methods and updates of the current technologies to capture and separate CO2 generated in a thermal power plant. Carbon capture is classified in two broad categories depending on the requirement of separation of CO2 from the gases. The novel methods of oxy combustion and chemical looping combustion carbon capture have been compared with the traditional post combustion and precombustion carbon capture methods. The current state of technology and limitation of each of the processes including commonly used separation techniques for CO2 from the gas mixture are discussed in this review. Further research and investigations are suggested based on the technological maturity, economic viability, and lack of proper knowledge of the combustion system for further improvement of the capture system.

“…Finally, the third phase involves supplementing oxygen with air in combusting oxy‐fuel . The oxy‐fuel combustion method generates a substantially low cost in separating and capturing CO 2 , due to which the International Energy Agency plans on commercializing and publically providing the oxy‐fuel combustion process to coal‐based power plants by 2020 . In the oxy‐fuel combustion process, flue gas is generated from fossil fuel burning with O 2 instead of normal air, which releases a reduced amount of N 2 as compared to that with H 2 O or CO 2 .…”

The extreme amount of greenhouse gases (GHGs) being released into the atmosphere has proved to be a globally challenging phenomenon that leads to changes in the climate and global warming. The amount of GHGs in the atmosphere has escalated immensely, with a substantial growth of 5.8% in 2010; a similar increase was observed in Pakistan as well. In Pakistan, carbon dioxide (CO2) emissions stand at 54% of total GHG emissions whereas methane, nitrous oxide, carbon monoxide and volatile organic carbon contribute to emissions at 36%, 9%, 0.75% and 0.3%, respectively. One of the key reasons for climatic changes is GHG emission generation from human interventions and activities related to transportation, urban development, industrialization, energy sources, farming and agriculture, waste's improper management, land use and forestry. In 2011, Pakistan's entire GHG emissions were a whopping 347 Mt of CO2‐eq, and by 2050, they are estimated to reach 4621 Mt CO2‐eq. This review evaluates and assesses GHG emissions generating from various sectors in Pakistan, in a socio‐scientific prospect that is caused by human activities and interventions in different economic sectors in Pakistan, endangering the environment across the country. Additionally, the review examines the current level of GHG emissions while accounting for China–Pakistan Economic Corridor–based emissions, abatement strategies including development of a state‐of‐the‐art technique for carbon capture and storage/utilization technologies in Pakistan. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…Perovskite based oxygen sorbents have the advantage of reversibly absorb and desorb oxygen at significantly lower temperatures (e.g. ≤ 600 • C), owing to their structural flexibility to accommodate significant amount of oxygen vacancies [30][31][32][33][34][35][36]. For example, La 0.1 Sr 0.9 Co 0.9 Fe 0.1 O 3-δ has a wide range of oxygen vacancy depending on temperature and oxygen partial pressure [37,38].…”

Chemical looping air separation (CLAS) is a promising technology for oxygen generation with high efficiency. The key challenge for CLAS is to design robust oxygen sorbents with suitable redox properties and fast redox kinetics. In this work, perovskite-structured Sr 1-x Ca x Fe 1-y Co y O 3 oxygen sorbents were investigated and demonstrated for oxygen production with tunable redox properties, high redox rate, and excellent thermal/steam stability. Cobalt doping at B site was found to be highly effective, 33% improvement in oxygen productivity was observed at 500 • C. Moreover, it stabilizes the perovskite structure and prevents phase segregation under pressure swing conditions in the presence of steam. Scalable synthesis of Sr 0.8 Ca 0.2 Fe 0.4 Co 0.6 O 3 oxygen sorbents was carried out through solid state reaction, co-precipitation, and sol-gel methods. Both co-precipitation and sol-gel methods are capable of producing Sr 0.8 Ca 0.2 Fe 0.4 Co 0.6 O 3 sorbents with satisfactory phase purity, high oxygen capacity, and fast redox kinetics. Large scale evaluation of Sr 0.8 Ca 0.2 Fe 0.4 Co 0.6 O 3 , using an automated CLAS testbed with over 300 g sorbent loading, further demonstrated the effectiveness of the oxygen sorbent to produce 95% pure O 2 with a satisfactory productivity of 0.04 g O2 g sorbent −1 h −1 at 600 • C.
