  • Patent number: 9186617
    Abstract: A method is described for separating CO2 and/or H2S from a mixed gas stream by contacting the gas stream with a non-aqueous, liquid absorbent medium of a primary and/or secondary aliphatic amine, preferably in a non-aqueous, polar, aprotic solvent under conditions sufficient for sorption of at least some of the CO2. The solution containing the absorbed CO2 can then be treated to desorb the acid gas. The method is usually operated as a continuous cyclic sorption-desorption process, with the sorption being carried out in a sorption zone where a circulating stream of the liquid absorbent contacts the gas stream to form a CO2-rich sorbed solution, which is then cycled to a regeneration zone for desorption of the CO2 (advantageously at <100° C.). Upon CO2 release, the regenerated lean solution can be recycled to the sorption tower. CO2:(primary+secondary amine) adsorption molar ratios >0.5:1 (approaching 1:1) may be achieved.

  • Patent number: 8845886
    Abstract: This invention relates to a process for separating a hydrocarbon stream via a filtration process to produce an upgraded permeate stream with decreased Conradson Carbon Residue (“CCR”) content. The invention involves the modification of a porous ceramic filter by functionalizing the surface of the ceramic filter with an multi-ring aromatic-diimide polymer. Preferably, the multi-ring aromatic-diimide polymer is comprised of a multi-ring aromatic monomer component. The functionalized filters of the present invention can be used in a process to selectively separate components of a hydrocarbon stream to produce an improved permeate (or “filtrate”) product stream with a lower CCR content and improved processing capabilities.
