Post combustion capture of CO2 from flue gases

Post combustion capture (PCC) is a good way for customers to capture CO 2 from flue gas streams and ensure compliance with increasingly strict emissions thresholds. With this technology, CO 2 is separated from the flue gas by scrubbing with a chemical solvent such as amine At a coal-fired power plant, CO2 is a component of the flue gas. The total pressure of the flue gas is 1 atm and the CO2 concentration is typically 10-15%. The process of transforming this low pressure, low concentration CO2 into a relatively pure CO2 stream is referred to as post-combustion CO2 capture. This capture step is typically followed b

Post-combustion entails separating CO2 from the exhaust gas of the power plant using chemical scrubbing. This technology, in principle, can be utilised in existing power plants without major modifications. Post-combustion is the most mature technology, although there is still significant uncertainty surrounding its use. The main problem is the low partial pressure of CO2 in the flue gas, which also contains other gases such as oxygen, water vapour and nitrogen Post-combustion capture is the term given to the capture of CO 2 from flue gases produced by the combustion of coal. Instead of being discharged directly to the atmosphere, flue gas is passed through equipment which separates out most of the CO 2. The CO 2is fed to a storage reservoir and the remaining flue gas i For post-combustion capture, CO2 is sequestrated from flue gas after fuels have completely burned. Pre-combustion capture involves the so-called integrated gasification combined cycle (IGCC) system, i.e. the syngas that is generated from coal gasification, mainly composed of CO and H2, is reformed by steam to produce a mixture of CO2 and H2 The two main challenges for post-combustion capture technologies include the large volumes of gas that must be handled, thus requiring large-scale equipment and resulting in high capital costs, and the amount of additional energy needed to operate the process. Post-combustion technologies enable approximately 90% of the CO 2 to be captured

Post Combustion Capture (PCC) Linde Engineerin

The principle of post-combustion capture is CO 2 separation from flue gas after combustion. Generally, the CO 2 in flue gas is diluted (8-15% CO 2) with inert gases such as nitrogen, argon, and water in addition to oxygen. Flue gases are normally at atmospheric pressure and high temperatures (between 320 K and 400 K) [ 39 - 41 ] An approach proposed for removal of CO2 from flue gas cools and compresses a portion of a recirculated flue-gas stream, condensing its volatile materials for capture. Recirculating the flue gas concentrates SOx, H2O and CO2 while dramatically reducing N2 and NOx, enabling this approach, which uses readily available industrial components

Figure 1: Schematic of post-combustion capture ( Adapted from [1]) In most cases, the power plant operates at atmospheri c pressure and hence, the partial pressure of CO 2 in the flue gas is low. In the case of pressurized combustion or with IGCC and IRCC, the partial pressure of CO2 is much higher In a post-combustion process, CO2 is separated and captured from the flue gases that result from the combustion of fossil fuel.

Absorption-based processes are the most promising options for CO2 capture from post-combustion flue gases at the present time. See more of #4 - Carbon Dioxide Capture and Storage - I (16003) See more of Fuels and Petrochemicals Division - Please See Topicals T2, T6, TA and T The flue gas recycle is beneficial for the overall capture process behaviour. The total flue gas flow rate is reduced with increasing flue gas recycle ratio. This reduction in the flue gas flow rate results in a smaller absorber column. The capital investment, the cost of electricity and cost of CO2 avoided are reduced with increasing the flue.

The CO2 concentration of flue gas from a natural‐gas‐fired power plant is only about 50% of that from a coal‐fired plant. In contrast, the O2 concentration is more than double, which makes it more difficult to capture CO2 from the former source.
