A Decision Support System for Underground CO2 Sequestration

Effect of CO2 capture on the emissions of air pollutants from industrial processes

“…The assumption of a linear relation between specific reboiler duty and flue gas CO 2 concentration can be justified for the range of CO 2 concentration considered in this study (3-13 vol%) according to literature (e.g., Alie et al, 2005;Egberts et al, 2003) 5 . The range for reboiler duty is not the lowest reported in the literature for existing solvents.…”

“…For retrofits, however, reboiler duty would be somewhat higher due to limited heat integration. Specific reboiler duty is indicated to be 30% higher for retrofits compared to new plants (Egberts et al, 2003). Taking into account that our study assumes retrofit CO 2 capture, we consider the assumed range for specific reboiler duty to be valid.…”

“…In this study, we assumed that CHP 5 The linear relation is not valid for CO2 concentrations above 15 vol%, where specific reboiler duty is reported to become nearly constant(Alie et al, 2005;Egberts et al, 2003).…”

A superstructure‐based mixed‐integer programming approach to optimal design of pipeline network for large‐scale CO2 transport

“…Some approaches, although not many, have been made to tackle this problem. Most early trials use a source‐sink matching method, where a carbon dioxide emission source and a sequestration sink are linked by a pipeline. This method aims to minimize the sum of capture cost, sequestration cost, and pipeline cost.…”

CCS from industrial sources

“…MEA scrubbing) and has the advantage that it can easily be applied as retrofit to existing plants at low technical risk [23]. However, unlike power plants, cement plants have limited low-grade waste heat available for solvent regeneration (typically only up to 30% of the total heat required for regeneration can be supplied by waste heat [24]. Thus, additional steam has to be generated or imported from elsewhere, increasing the cost of capture significantly.…”
