  • Patent number: 11433351
    Abstract: A system and method for recovering carbon dioxide from a stream of gas using an absorption unit configured to receive the stream of gas and a stream of liquid absorbent. The gas includes carbon dioxide and vaporized water, and the liquid absorbent is chemically reactive with the carbon dioxide to form a solidified carbon dioxide-rich absorbent material. The gas and the liquid absorbent are mixed in the absorption unit such that a slurry that includes the solidified carbon dioxide-rich absorbent material and condensed water is formed therein. The system and method may also employ a transport mechanism coupled in communication with the absorption unit, wherein the transport mechanism is configured to channel the slurry downstream from the absorption unit.
    Type: Grant

  • Patent number: 9919263
    Abstract: An amino-siloxane composition is presented. The amino-siloxane composition includes structure (I): wherein R1 is independently at each occurrence a C1-C5 aliphatic radical; R2 is a C3-C4 aliphatic radical; R3 is a C1-C5 aliphatic radical or R4, wherein R4 comprises structure (II): and X is an electron donating group. Methods of reducing an amount of carbon dioxide in a process stream using the amino-siloxane composition are also presented.

  • Patent number: 9890183
    Abstract: The present invention is directed to aminosilicone solvent recovery methods and systems. The methods and systems disclosed herein may be used to recover aminosilicone solvent from a carbon dioxide containing vapor stream, for example, a vapor stream that leaves an aminosilicone solvent desorber apparatus. The methods and systems of the invention utilize a first condensation process at a temperature from about 80° C. to about 150° C. and a second condensation process at a temperature from about 5° C. to about 75° C. The first condensation process yields recovered aminosilicone solvent. The second condensation process yields water.
