Abstract: High energy demand has led to the increased power production from the fossil power plants which are the largest source of CO₂. Monoethanolamine-based post-combustion CO₂ capture is a developed technology to mitigate CO₂, however, it still needs attention towards process modification concerning energy requirements. Rich solvent flashing is the suggested modifications which is discussed in the present work and is used to minimise the overall energy. The minimum reboiler duty was observed at 20%, 30% and 40% split of the lean solvent at certain approach temperatures. The reboiler duty of 3.201 MJ/kg CO₂ was observed at the approach temperatures of 5°C and 10°C with the split fraction of 40%. The system is also modelled using single, double and three flash drums where three flash drums indicates the minimum duty with 5% decrease from the base case model.
