TPI Biogas Upgrading Systems

Membrane and selective solvent technologies for biomethane production.

High-Efficiency Biomethane Production

Clarke Energy is an authorised distributor and service provider for Tecno Project Industriale (TPI) biogas upgrading plants. These include both membrane separation systems and selective solvent-based washing systems, enabling raw biogas to be upgraded into high-quality biomethane for grid injection, transport fuel, or industrial gas use.

TPI biogas upgrading systems are engineered for reliable long-term operation across a wide range of plant capacities and inlet gas conditions. Technology selection is based on gas flow rate, methane concentration, carbon dioxide content, recovery targets, and site-specific requirements, ensuring each installation achieves high methane purity, low methane slip, and stable performance under variable operating conditions.

About TPI Biogas Upgrading Systems

TPI designs and supplies advanced biogas upgrading plants that remove carbon dioxide and trace impurities from raw biogas to produce specification-compliant biomethane. Systems are deployed globally across agricultural, waste, wastewater, and industrial biogas applications and are designed for continuous operation in demanding environments.

TPI’s portfolio includes two proven upgrading routes — membrane separation and selective solvent absorption — allowing each project to be matched to the most appropriate process from both a technical and commercial perspective.

TPI Membrane Biogas Upgrading Systems

TPI membrane upgrading systems use multi-stage polymer membranes to selectively separate carbon dioxide and other non-methane components from biogas. The modular design allows systems to be configured for a wide range of flow rates and expanded as gas production increases.

Typical characteristics include:

• Biomethane methane concentrations typically above 97%
• Modular, compact plant layout with reduced space requirements
• Low chemical consumption and simplified operation
• High availability with minimal routine maintenance
• Flexible configuration to accommodate variable inlet gas quality

Membrane systems are commonly selected for small to medium-scale plants, sites with limited footprint, or projects requiring scalable capacity growth.

TPI Selective Solvent Biogas Upgrading Systems

TPI selective solvent upgrading systems use physical or chemical solvents to absorb carbon dioxide and trace components from biogas. The solvent is regenerated and reused, producing a high-purity methane stream with very low methane losses.

Typical characteristics include:

• High methane recovery with minimal methane slip
• Stable biomethane quality across fluctuating inlet conditions
• Suitability for higher gas flow rates and large-scale installations
• Proven compliance with demanding grid injection specifications
• Long service life with established process control strategies

Selective solvent systems are often preferred where maximum methane yield, high throughput, or very stable output quality is required.

Applications for TPI Biogas Upgrading Systems

TPI biogas upgrading technology is suitable for a wide range of renewable gas applications, including:

• Agricultural anaerobic digestion plants
• Food waste and organic waste treatment facilities
• Wastewater treatment works
• Industrial biogas recovery projects
• Biomethane production for grid injection or transport fuel

Frequently Asked Questions about TPI Biogas Upgrading Systems

Technical and Engineering

K
L
What is biogas upgrading and how does it work?

Biogas upgrading is the process of removing carbon dioxide and trace impurities from raw biogas to increase methane concentration. TPI upgrading systems use either membrane separation or selective solvent absorption to produce high-quality biomethane suitable for grid injection, transport fuel, or industrial use.

K
L
What technologies are used in TPI biogas upgrading systems?

TPI supplies two proven technologies: membrane separation systems, which selectively separate gases using multi-stage membranes, and selective solvent systems, which absorb carbon dioxide using a regenerable solvent. The most suitable technology is selected based on gas flow rate, composition, and methane recovery requirements.
