Abstract

In this study, we analyze two design configurations for post-combustion carbon capture (PCC) namely inter-stage cooling and split flow. The results show that inter-stage cooling configuration has notable impact on improving PCC performance. It is found that, for a flue gas with 13.0 mol% of CO ₂, and with objective of capturing 90% of CO ₂ at purity of 98%, base case configuration imposes a 4.7GJ/ton-CO ₂ reboiler duty. This energy burden decreases (about 34.8%) to 3.1 GJ/ton-CO ₂ with single-stage cooling configuration. Two-stage-cooling configuration further improves the efficiency but only incrementally. Similarly, split flow design configuration shows considerable improvement in efficiency (3.8GJ/ton-CO ₂ vs. 4.7GJ/ton-CO ₂ for base case).
