Abstract:
1. A gas scrubbing apparatus including: at least two modules, each module including at least one process vessel adapted for use in a gas scrubbing process in which a gas stream contacts a regenerable liquid absorption medium in an absorber, carbon dioxide being absorbed from the gas stream into the regenerable liquid absorption medium, the absorbed carbon dioxide being subsequently stripped from the regenerable liquid absorption medium in a regenerator to regenerate the liquid absorption medium for return to the absorber, each process vessel being selected from an absorber, a regenerator, a scrubber, a reboiler, a heat exchanger or a combination thereof, each process vessel having a top wall, a base wall, and at least three sidewalls formed from a cementitous material, each process vessel having inlet and outlet ports for fluid entering and leaving the process vessel when in use, formed within at least one of the top wall, base wall, or sidewall of each process vessel, wherein the sidewalls of each process vessel define a polygon shaped cross-section, wherein at least one side wall of a first process vessel in a first module can be connected or abutted to at least one side wall of a second process vessel in a second module, wherein each module includes at least two process vessels selected from an absorber, regenerator, gas scrubber, reboiler or heat exchanger, wherein each module includes at least one absorber and at least one regenerator, the gas scrubbing apparatus further including at least one heat exchanger in fluid communication with at least one of the at least one regenerator or the at least one absorber, the at least one heat exchanger being located under the base of the respective regenerator or absorber.
