  • Once through COabsorber with integrated ammonia slip mitigation and intercooling
    Patent number: 12722115
    Abstract: A process of removing CO2 includes: contacting, in a first absorber stage, a CO2-containing gas stream with a solution mixture to generate a partially cleaned gas stream; contacting, in a second absorber stage, the partially cleaned gas stream with a CO2-lean solution to generate a further cleaned gas stream that contains ammonia and a CO2-partially-enriched solution; dividing the CO2-partially-enriched solution into a first portion and a second portion; removing the first portion of the CO2-partially-enriched solution from the second absorber stage; chilling the removed CO2-partially-enriched solution; contacting, in the third absorber stage, the chilled CO2-partially-enriched solution with the further cleaned gas stream that contains ammonia to generate a treated gas stream and a CO2-partially-enriched-solution containing recovered ammonia; and combining the solution containing the recovered ammonia removed from the third absorber stage with the second portion of the CO2-partially-enriched solution, forming
