Abstract: Devices, systems and methods for capturing CO2 in a form that can be stored, processed, and/or converted to usable products is desirable. Systems capture CO2 using small scale, individual devices at a vast number of locations which, in the aggregate, are capable of significantly decreasing CO2 concentrations in the atmosphere on a global scale. When such small devices are placed in areas already occupied with a structure, i.e., office buildings, apartments, homes, automobiles and the like, though the amount of CO2 removal by each individual device may be relatively small, in the aggregate, significant amounts of CO2 may be removed at a more macro or even global scale.

Abstract: The combined acid gas removal and water filtration system (10) removes sour gases, such as hydrogen sulfide (H2S) and carbon dioxide (CO2), from an input gaseous hydrocarbon stream (FG), as well as producing purified water (TW).
