Helium Membrane

Product Overview

The helium membrane system is a high-efficiency gas separation solution based on advanced polymer membrane technology for helium extraction and purification.

Using high-performance polymer membranes, the system selectively separates different gas components, enabling efficient recovery and purification of helium even from low-concentration sources.

With a compact structure, stable operation, and low energy consumption, this technology is widely used in helium recovery from natural gas and the production of high-purity helium.

Working Principle

The helium membrane utilizes polymeric membranes (typically polyimide) to separate gases based on differences in solubility and diffusion rates.

When a partial pressure difference exists across the membrane, gases with higher permeability—such as H₂O, H₂, and He—pass through the membrane more quickly and are enriched on the low-pressure side. In contrast, gases with lower permeability—such as N₂, CH₄, and other hydrocarbons—remain on the high-pressure side.

Through this process, helium can be separated and further purified in multiple stages.
