Abstract

The regeneration energy requirement of the GV low-energy CO2 removal process, based on the Hot Potassium Carbonate (HPC) solution, can be drastically reduced by integration with a stand-alone physical absorption system. A small sized physical unit added upstream the existing CO2 Removal system allows the pre-absorption from 30 to 50% of the CO2 from the Process Gas which is then fully recovered by flash free from any need of regeneration energy requirement.
