  • Publication number: 20230356145
    Abstract: Disclosed herein is a method and system for CO2 removal from a gas stream using a diamine solvent having a Formula I R1(R2)N?L1?NH—R3??Formula I. With respect to Formula I, each of R1 and R2 independently is aliphatic, cycloaliphatic, or R1 and R2 together with the nitrogen to which they are attached, form a heterocyclyl ring; L1 is aliphatic, cycloaliphatic, or L1 and R1 together with the nitrogen to which they are attached form a heterocyclyl ring; and R3 is aliphatic, cycloaliphatic, cycloalkylalkyl, or alkoxyalkyl. And/or the compound may have a viscosity of less than 75 cP at a CO2-loading of 40 mol % and at a temperature of 40° C.

  • Patent number: 10773205
    Abstract: A class of water lean, organic solvents that can bind with various acid gasses to form acid gas bound molecules having a high degree of intramolecular hydrogen bonding which enables their use as regenerable solvents for acid gas capture. Unlike the other devices described in the prior art, the present invention takes advantage of shortened distances between the portions of the molecule that form hydrogen bonds within the structures when loaded with an acid gas so as to create a molecule with a higher internal bonding affinity and a reduced proclivity for agglomeration with other molecules.
