VERDEMOBIL BIOGAZ and SWEP – creating pure CH4, CO2, and H2 from lean biogas

The customer: VERDEMOBIL BIOGAZ, a pioneering French company that specializes in the valorization of renewable gases, including BioCH4, BioCO2, and BioH2.

The challenge: Develop a system that uses cryogenic distillation to cool and purify lean biogas, while consuming minimal energy.

The solution: SWEP designed and sized brazed plate heat exchangers, which are key to the process of purifying CO2, specifically for VERDEMOBIL BIOGAZ.

The heat exchangers: For VERDEMOBIL BIOGAZ, SWEP has installed countless different types and sizes of BPHEs, with different flow rates, across 6 different system designs.

The results: Pure, liquid CO2

Purifying biogas

The purification of biogas into biomethane generates two primary streams: Biomethane and lean gas, also called “off gas,” which is primarily composed of carbon dioxide. At their installations, VERDEMOBIL BIOGAZ captures, purifies, liquefies, and distills this gas, allowing for the valorization of 100% of the biogas, with zero discharge of CH₄ or CO₂ into the atmosphere.

The role of SWEP brazed plate heat exchangers

SWEP brazed plate heat exchangers play a crucial role at many stages of VERDEMOBIL BIOGAZ’s innovative cryogenic systems, including:

Pre-cooling
Liquefaction
Heat recovery
Vaporization
Condensing process and auxiliary fluids

Why choose SWEP?

Kevin PREAU, Engineering Manager at VERDEMOBIL BIOGAZ, expresses satisfaction with the long-term relationship between SWEP and VERDEMOBIL BIOGAZ.

“The choice of SWEP brazed plate heat exchangers stems from their wide range of products, offering a compact design for space optimization and system customization. Regarding cost, service and team responsiveness to deadlines, SWEP receives an A+ rating from VERDEMOBIL BIOGAZ.”
