Title:
【発明の名称】1-カルバ-2-ペネム-3-カルボン酸
Document Type and Number:
Japanese Patent JPS6033836
Kind Code:
B2
Abstract:
A process for separating and recovering organic vapors (e.g., chlorofluorocarbons) from a feed stream of organic vapors and air wherein organic vapors are present in the "window concentration" range being too high for conventional carbon adsorption and too low for efficient compression/condensation recovery. By passing the organic vapor and air feed stream through the feed side of a semipermeable membrane unit, a vapor depleted stream exiting the membrane unit can then be processed by conventional carbon adsorption while a vapor enriched stream from the membrane unit can be processed by conventional compression and condensation.
