Biogas Purification & Liquefaction Plant
Modular Design
All stages of the process—gas purification, drying, and liquefaction—are integrated into eight compact modules assembled in a Plug & Play format.
Compact Size
All technological equipment is housed on a platform with dimensions of 14.0 m (length) x 2.9 m (width) x 9.5 m (height).
Operational Flexibility
The system is designed to handle biogas of various compositions, including gas with high CO₂ and H₂S content. It can also be customized to meet specific technical requirements.
High Automation
The fully automated system eliminates the need for constant operator presence, significantly reducing operational costs.
Eco-Friendliness
The plant employs an air-based cryogenic cycle, which is safe for the environment and free of chemical refrigerants
Unit capacity
Biomethane: 160 Sm3/h
BioLNG: 110 kg/h 2.65 TPD
PROCESS #1: Processing biogas into high-purity biomethane
Removal of all components H₂S, VOCs, CO₂ & H₂O from biogas to obtain highly purified biomethane (LNG spec).
M0 - Frame
M1 - Biogas desulfurization and pre-compression
M2 - Amine gas treating
M3 - Compression and dehydration of biomethane
PROCESS #2: Biomethane liquefaction
The biomethane is liquefied in a Brazed Aluminum Heat Exchanger using a Reverse Brayton Cycle in which dry air is compressed and expanded down to -165°C.
M5 - Biomethane liquefier
PROCESS #3: Central services
The biomethane is liquefied in a Brazed Aluminum Heat Exchanger using a Reverse Brayton Cycle in which dry air is compressed and expanded down to -165°C.
M4 - Dry air generator
M6 – Industrial Chiller
M7 - Air Dry cooler (Adiabatic Cooler for hot country)
M8 - Power and control room
