Title:
The facilitated transport film for separating an aromatic series from a non-aromatic compound
Document Type and Number:
Japanese Patent JP6188731
Kind Code:
B2
Abstract:
Certain embodiments of the invention provide an apparatus for separating aromatic hydrocarbons from an aromatic hydrocarbon feed stream. The apparatus includes a membrane support, and a hydrophilic polymer membrane matrix disposed on the membrane support. The hydrophilic polymer membrane matrix includes an effective amount of polyvinyl alcohol and an effective amount of sodium alginate. The apparatus further includes a carrier agent bonded to the hydrophilic polymer membrane matrix using a cross-linking agent. The carrier agent exhibits a greater affinity for aromatics compared to aliphatics. The apparatus further includes a membrane housing configured to hold the membrane support. The membrane housing includes an inlet, a permeate outlet, and a retentate outlet, the inlet being operable to receive the aromatic hydrocarbon feed stream, the permeate outlet being operable to discharge a permeate stream, and the retentate outlet being operable to discharge a retentate stream.
