  • Publication number: 20240307820
    Abstract: Processes for solvent-based CO2 capture are described. The processes incorporate overhead vapor compression which increases the condensation temperature of water in the CO2 stripper allowing for recovery of the latent heat of the water vapor to be recovered. The processes utilize a CO2 stripping column, a compressor in the column total overhead, and a heat exchanger exchanging heat between the compressed total overhead and a portion of the rich solvent.

  • Publication number: 20240092638
    Abstract: Methods of producing a hydrogen-enriched product and recovering CO2 are described. A synthesis gas stream from a hydrogen production process unit is separated in a hydrogen pressure swing adsorption unit into a high-pressure hydrogen stream and a hydrogen depleted tail gas stream, and the hydrogen depleted tail gas stream is compressed. The compressed tail gas stream is separated in a CO2 fractionation system into a CO2-enriched product stream and an overhead stream. The overhead stream is separated in an overhead hydrogen PSA system into a second high-pressure hydrogen stream and a low-pressure tail gas stream. The first and second high-pressure hydrogen streams and the CO2-enriched product stream are recovered. The low-pressure tail gas stream from the overhead hydrogen PSA system is combusted with oxygen to produce steam, electricity, or both.
