  • Azide crosslinked and physically crosslinked polymers for membrane separation
    Patent number: 9174175
    Abstract: The present invention appreciates that compounds comprising ester linkages and nitrogen-containing moieties that are at least divalent (e.g., urea, urethane, amide, etc.) can be crosslinked with azides to form membranes that are resistant to CO2 plasticization, that are selective for acid gases relative to nonpolar gases such as hydrocarbons, and that have high acid gas flux characteristics. The resultant membranes have stable structure and stable separation properties at higher temperatures and pressures. The membranes are compatible with many industrial processes in which polar gases are separated from nopolar gases. In an exemplary mode of practice, the membranes can be used to separate acid gases from the hydrocarbon gases in natural or non-acid gas components of flue gas mixtures (e.g., N2, O2, etc.).

  • Process for making alkoxylated piperazine compounds
    Patent number: 9169222
    Abstract: The present invention relates to an improved process for making mono- and di-alkoxylated piperazine compounds especially dihydroxyethylpiperazine. The improvement comprises the addition of an acid to the piperazine compound prior to the addition of an alkylene oxide to a reactor wherein the alkoxylated piperazine compound is prepared. Said improvement reduces the concentration of undesirable glycol ether byproducts which contribute undesirable color and foaming of the alkoxylated piperazine compounds.

  • Radiation cured membranes derived from polymers that are co-reactive with azide crosslinking agent(s)
    Patent number: 9169367
    Abstract: The present invention appreciates that compounds comprising nitrogen-containing moieties that are at least divalent (e.g., urea, urethane, amide, etc.) can be reacted with azides using at least radiation energy to initiate the reaction between at least a portion of the compounds and the azides to form membranes that have surprisingly high selectivities for acid gases relative to nonpolar gases such as hydrocarbons. The membranes are also resistant to CO2 plasticization and have high acid gas flux characteristics. The resultant membranes can be extremely thin (e.g., 10 micrometers or less), which promotes high permeability for the acid gas and can translate into high productivity on a scaled-up, industrial level.
