Thermax Ne0 showcases the true potential of VSA technology in biogas upgradation

Project overview

Vacuum swing adsorption (VSA) technology for biogas upgradation had limited acceptance in India due to performance concerns and operational challenges.

At one of the country’s largest biogas projects, Thermax Ne0 implemented an indigenous VSA-based solution to demonstrate the technology’s reliability, scalability, and effectiveness in real-world operating conditions.

Challenges

Skepticism around VSA technology due to adsorbent degradation and methane losses.
Concerns about scalability and long-term operational reliability.
Limited industry confidence in VSA-based biogas purification solutions.

Solution

Installed an in-house developed VSA-based biogas upgradation unit.
Designed to process biogas generated from multiple feedstocks.
Enabled purification and upgrading of raw biogas into high-quality biomethane.
Implemented at a large-scale biogas facility to validate real-world performance.

Result

Consistently achieved over 96% methane purity.
Maintained methane losses below 3%, meeting industry benchmarks.
Enabled supply of upgraded biomethane to CNG stations for automotive use.
Demonstrated the viability of VSA technology as a reliable and cost-effective solution for biogas upgradation in India.
