Abstract
The goal of reducing the energy consumption of the CO2 removal process from flue gas may be pursued by modifying the process flow system, insertion of new technical solutions or developing new solvents. This paper provides data and discussion of the pilot plant experimental results using an aqueous 2-(2-aminoethylamino)ethanol (AEEA) compared to ethanolamine (MEA) solution. The post-combustion carbon capture pilot plant study was conducted with stripper inter-heating for advanced various flow systems, mainly for multi absorber feed (MAF) process setups, namely one with the lean amine stream being split 50/50 and served at different heights of the absorption column. A comparison with the standard (S) and split flow (SF) process flow modification has been also performed. The test showed that unskillful running of the process with AEEA solution can lead to excessive heat consumption, higher than for MEA.
