CRA x Adani Infra: Engineered Compression Skid Un-locks Higher Biogas Yields

Adani Infra (India) required a safe, continuous, and efficient method to recirculate Biogas into its digester system.

The solution had to:

• Operate continuously at defined flow and pressure conditions.
• Meet safety and automation needs within a compact footprint.
• Integrate smoothly with existing plant infrastructure and control systems while adhering to the complex boundary conditions.

CRA engineered and delivered a compact, skid-mounted Biogas compression system equipped with the following core components:

‍

• Compressor Type: Rotary Sliding Vane (Ro-Flo Compressors.
• Rated Flow: 250 Nm³/hr
• Discharge Pressure: 9–10 psi

‍

CRA’s relationship with Ro-Flo improves the quality and customizability of our compressors. The system includes solenoid valves for automated operation, enabling controlled gas distribution. CRA also aided in integrating the package with Adani Infra's systems for reliable performance.

‍

• Improved Digester Performance: Consistent and controlled Biogas recirculation enhanced microbial activity.
• High Operational Reliability: An automated valve system and dedicated backup compressor per channel ensured high redundancy.
• Optimized Process Control: Flexible Biogas distribution enabled better biological efficiency and system responsiveness.
• Seamless Integration: CRA’s long-standing partnership with a veteran compressor manufacturer ensured seamless system integration and high customizability.
• On-Time Delivery: The System was designed, built, tested, and commissioned within agreed timelines.

CRA has proudly showcased its exceptional capability in designing and implementing specialized engineering solutions for biogas systems and compressor skids. This project serves as a testament to CRA's expertise in seamlessly merging mechanical systems with intelligent automation, effectively meeting the distinct operational requirements of cutting-edge energy infrastructure.
