  • Process for removal of selected component gases from multi-component gas streams
    Patent number: 5382417
    Abstract: A method of purifying multi-component gas streams, comprising the steps of stabilizing an absorbent solution which comprises a Group I-B metal halide amine, contacting said absorbent solution with said multi-component gas stream, complexing ligands and reactable components in said gas stream with said Group I-B metal halide amine, decomplexing and recovering said ligands and reactable components either separately or in mixture, and recycling said absorbent solution for contact with said multi-component gas stream.
    Type: Grant

  • Use of amine-aluminum chloride adducts as alkylation inhibitors in a ligand-complexing process
    Patent number: 4353840
    Abstract: In processes in which liquid sorbents that are solutions in an aromatic hydrocarbon or halogenated aromatic hydrocarbon of a bimetallic salt complex having the generic formula M.sub.I M.sub.II X.sub.n.Aromatic, wherein M.sub.I is a Group I-B metal, M.sub.II is a Group III-A metal, X is halogen, n is the sum of the valences of M.sub.I and M.sub.II, and Aromatic is a monocyclic aromatic hydrocarbon or halogenated aromatic hydrocarbon are used to separate complexible ligands from a gas feedstream that comprises an olefin having 2 or 3 carbon atoms, alkylation of the aromatic hydrocarbon or halogenated aromatic hydrocarbon is inhibited by incorporating in the liquid sorbent from 8.5 mole percent to 30 mole percent, based on the Group I-B metal in the liquid sorbent, of an amine-aluminum chloride adduct, such as ammonia-aluminum chloride adduct or pyridine-aluminum chloride adduct.
