ACID TOLERANT POLYMERIC MEMBRANE AND PROCESS FOR THE RECOVERY OF ACID USING POLYMERIC MEMBRANES |
| 摘要 |
A multi-layer membrane structure including a crosslinked polymeric membrane, such as a crosslinked polyvinyl sulfate membrane or a crosslinked copolymer polyvinyl sulfate and polyvinyl alcohol membrane, is provided. The membrane structure is suitable for use in an acid environment, and is suitable for recovering acid from a feed mixture comprising acid, hydrocarbons and water.
