Research on the fabrication and application of selective membranes in gasoline vapor recovery
Abstract
This paper presents the results of a study devoted to developing a selective membrane for separating hydrocarbons from mixtures with air. The approach involves applying a selective coating onto a substrate and packaging it in a spiral wound configuration for use in a gasoline vapor recovery system at fuel stations.
The membrane is fabricated using a 0.45 µm PTFE substrate with an RTV 828 coating, offering high selectivity and permeability, a straightforward process, low cost, and scalability. Testing in a gasoline vapor recovery system demonstrated a recovery efficiency of over 90%, highlighting its potential for industrial applications and environmental protection.
