| Abstract | A critical component in the assessment of long-term risk from geologic sequestration of carbon dioxide (CO$_{2}$) is the ability to predict mineralogical and geochemical changes within storage reservoirs as a result of rock-brine-CO$_{2}$ reactions. Impurities and/or other constituents in CO$_{2}$ source streams selected for sequestration can affect both the chemical and physical (e.g., density, viscosity, interfacial tension) properties of CO$_{2}$ in the deep subsurface. The nature and concentrations of these impurities are a function of both the industrial source(s) of CO$_{2}$, as well as the carbon capture technology used to extract the CO$_{2}$ and produce a concentrated stream for subsurface injection and geologic sequestration. Most work on CO$_{2}$ capture, utilization, and storage has been focused on large fossil-fuel-fired power plants. This article reviews the relative concentrations of CO$_{2}$ and other constituents in exhaust gases from other major non-power-related industrial point sources. Assuming that carbon capture technology would remove most of the air (i.e., incondensable gases N$_{2}$, O$_{2}$, and Ar) from the exhaust gases, the authors summarize the relative proportions of SO$_{2}$, NO$_{x}$ and other remaining impurities expected to still be present in non-power-related CO$_{2}$ source streams that could be targeted for geologic sequestration. The summary is presented relative to the four largest non-power-related sources of CO$_{2}$: (1) use of fossil fuels as carbon feedstock, (2) iron, steel, and metallurgical coke production, (3) lime and Portland cement production, and (4) natural gas processing and industrial heat/steam generation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
