“…Certain levels of NO x and SO 2 are reported for two of the double flashing cases but these species are reported to be completely removed using the Air Products sour compression process. The distillation case from the COORAL project (Kather and Kownatzki, 2011;Kather et al, 2013) reports very high purity CO 2 at 99.94 % v/v; however, the CO 2 purity of the distillation case reported by Pipitone and Bolland (2009) is lower at 99.3 % v/v.…”

“…Data used to compile the table are taken from the COORAL project (Kather and Kownatzki, 2011;Kather et al, 2013), a collaborative industrial paper (Wilkinson et al, 2001), a study from the Norwegian University of Science and Technology (NUST) by Pipitone and Bolland (2009), an IEA report (Dillon et al, 2005), a paper written by Air Products (White et al, 2009) and a report on the Callide oxyfuel demonstration project (Spero et al, 2014). Table 3 shows the raw/dehumidified CO 2 has a purity in the range of 74.8 -85 %, with the main impurities being O 2 , N 2 and Ar which arise from excess oxidant and air ingress.…”

For CO 2 capture and storage deployment, the impact of impurities in the gas or dense phase CO 2 stream arising from fossil fuel power plants, or large scale industrial emitters, is of fundamental importance to the safe and economic transportation and storage of the captured CO 2 . This paper reviews the range and level of impurities expected from the main capture technologies used with fossil-fuelled power plants in addition to other CO 2 emission-intensive industries. Analysis is presented with respect to the range of impurities present in CO 2 streams captured using pre-combustion, post-combustion and oxy-fuel technologies, in addition to an assessment of the different parameters affecting the CO 2 mixture composition. This includes modes of operation of the power plant, and different technologies for the reduction and removal of problematic components such as water and acid gases (SO x / NO x ). A literature review of data demonstrates that the purity of CO 2 product gases from carbon capture sources is highly dependent upon the type of technology used. This paper also addresses the CO 2 purification technologies available for the removal of CO 2 impurities from raw oxy-fuel flue gas, such as Hg and noncondensable compounds. CO 2 purities of over 99 % are achievable using post-combustion capture technologies with low levels of the main impurities of N 2 , Ar and O 2 . However, CO 2 capture from oxy-fuel combustion and integrated gasification combined cycle power plants will need to take into consideration the removal of non-condensables, acid gas species, and other contaminants. The actual level of CO 2 purity required will be dictated by a combination of transport and storage requirements, and process economics.

“…Depending on the applied capture technology, there are different types and amounts of impurities in the captured CO 2 streams. Literature data collated in [23] was used to define CO 2 stream compositions of the different plants and capture facilities (Table 2). The compositions of all CO 2 streams captured with the same capture technology were assumed to be equal, with the exception of cement plants: As the used fuel does not contain sulfur, there is also no SO x in the generated CO 2 stream.…”

“…Instead, there is a proportionally greater proportion of the remaining impurities listed for the other post-combustion capture (PCC) plants (data not included in Table 2). The H 2 O concentration of captured CO 2 streams was limited to 50 ppm v in the scenarios following [23,24]. Each emitter's CO 2 stream composition was assumed to be constant over time.…”

Temporal variations in CO2 stream composition and mass flow rates may occur in a CO2 transport network, as well as further downstream when CO2 streams of different compositions and temporally variable mass flow rates are fed in. To assess the potential impacts of such variations on CO2 transport, injection, and storage, their characteristics must be known. We investigated variation characteristics in a scenario of a regional CO2 emitter cluster of seven fossil-fired power plants and four industrial plants that feed captured CO2 streams into a pipeline network. Variations of CO2 stream composition and mass flow rates in the pipelines were simulated using a network analysis tool. In addition, the potential effects of changes in the energy mix on resulting mass flow rates and CO2 stream compositions were investigated for two energy mix scenarios that consider higher shares of renewable energy sources or a replacement of lignite by hard coal and natural gas. While resulting maximum mass flow rates in the trunk line were similar in all considered scenarios, minimum flow rates and pipeline capacity utilisation differed substantially between them. Variations in CO2 stream composition followed the power plants’ operational load patterns resulting e.g., in stronger composition variations in case of higher renewable energy production.
