REVOLUTIONING BIO-LNG PRODUCTION

As the world races toward cleaner energy solutions, bio-LNG (liquefied biomethane) has emerged as a vital component of greenhouse gas emission reduction strategies. However, traditional bio-LNG production methods often involve complex and energy-intensive purification steps, limiting scalability and cost efficiency. Enter a groundbreaking innovation that may change the game for the biogas industry: the PRISM® GreenSep LNG membrane separator by Air Products.  
 

The Growing Demand for Bio-LNG Solutions  

The renewable energy market continues to expand rapidly as governments and industries push for greener solutions to mitigate climate change. Bio-LNG, derived from organic sources such as food waste, animal waste, and municipal waste, plays a key role in this transition. According to industry forecasts, the demand for renewable LNG solutions is expected to grow exponentially in the coming decade. However, achieving high production yields while minimizing operational costs remains a significant challenge for producers.  
 

Innovating with the PRISM® GreenSep LNG Membrane Separator  

Air Products, a global leader in gas separation and purification membranes, recently introduced the PRISM® GreenSep LNG membrane separator, which simplifies and optimizes bio-LNG production. This advanced technology eliminates the need for traditional purification methods, such as amine scrubbing and thermal swing adsorption, streamlining the process.  
The innovation is put to work in the second stage of the cycle, where a series of membranes utilize a concept called “sweep”. The permeate of the downstream membrane sweeps the low-pressure side of the upstream membrane in the series, significantly improving the CH4/CO2 separation.  

Key benefits of Air Product technology include:  

• Higher Yields: The membrane’s efficiency maximizes the conversion of biomethane into LNG, ensuring better output from the same feedstock.  

• Lower Operational Costs: By eliminating intermediate purification steps, the system reduces maintenance and energy expenses.  

• Environmental Benefits: A more efficient production process results in a lower carbon footprint, supporting global sustainability initiatives.    
  
   

Meeting Industry Needs with Innovation  

As bio-LNG becomes an increasingly important strategy to reduce emissions across various sectors, innovations like the PRISM® GreenSep membrane separator will play a critical role in shaping the future of renewable energy. By simplifying operations and cutting costs, this technology makes bio-LNG production more scalable and accessible for producers worldwide.  
Air Products has a long history of pioneering advancements in membrane technology, and this innovation strengthens its position as a leader in the energy transition.
