CO2-selective permeation membranes for biogas and hydrogen-containing gas
Membrane-separation capability aimed at selectively removing CO2 from biogas and hydrogen-containing process gas in lower-carbon energy systems.
AI-assisted directory summary. Technical specifications, performance metrics, readiness and compliance labels are unverified unless individually supported and reviewed. Proposed partnership routes do not establish supplier consent, export eligibility, or willingness to sign an NDA. Confirm claims and test conditions with the linked sources and supplier before procurement or citation.
Problem solved
Addresses CO2 removal from gas streams where gas upgrading or hydrogen purification requires a potentially lower-energy alternative to bulk thermal separation.
Application contexts
- Biogas upgrading
- Hydrogen-containing gas purification
- CO2 capture from energy-process gas
Technical principle
A CO2-selective permeation membrane preferentially transfers CO2 across the membrane relative to other gas components; the company identifies applications in biogas upgrading, hydrogen-containing gas, natural-gas fields, LNG facilities, and CO2 capture contexts.
Typical use cases
- CO2 removal during biomethane upgrading
- CO2 separation from hydrogen-containing gas
- Membrane-based capture feasibility studies for process gas
