GPE is your partner to redefine the future of renewable energy with our state-of-the-art Biogas Upgradation Plants, designed to meet the rising global demand for sustainable, high-purity biomethane. India has long used wet digestor-based biogas systems, but these often-lacked efficient upgradation solutions. Leveraging German-engineered advanced Membrane and high pressure Multibed PSA Technology, our solutions will set the industry benchmark in efficiency, reliability, and environmental stewardship. Designed to capture more and help clients meet global emissions standards while maximizing CBG output.
Our BUPs upgrade raw biogas into pipeline-grade biomethane (Bio-CNG) by selectively separating CO₂, H₂S, moisture, and other impurities while ensuring:
Ultra-Low Methane Slippage: Methane is over 80x more potent than CO₂ in its global warming potential, as well as methane contributes to ground-level ozone formation. At GPE, we understand that every molecule matters. Our systems are engineered to deliver lowest methane slippage to environment, preserving both value and nature.
Dual Technology Edge: Two world-class upgrading technologies—Membrane for energy-efficient, compact solutions, and multibed High-Pressure PSA for superior separation precision. This hybrid capability allows us to tailor solutions for diverse feedstocks and project scales.
We offer cutting-edge Biogas Upgradation Plants based on advanced Membrane Technology, in strategic association with Evonik and Ube — two of the world’s most respected names in membrane innovation. By integrating globally acclaimed membranes with our decades of in-house gas processing expertise, GPE delivers next-generation membrane-based BUPs that are highly efficient, maintenance-friendly, and tailor-made for India’s evolving CBG infrastructure.
Membrane-based BUPs use polymeric hollow fiber membranes that selectively allow CO₂, H₂O, and other impurities to pass through while retaining high-purity methane. The result is a dry, compressed biomethane stream suitable for compression, bottling, or pipeline injection. We use multi-stage membrane modules from Evonik and Ube, offering exceptional selectivity, stability, and throughput. The complete BUP is engineered, packaged, and integrated entirely in-house by GPE, ensuring complete control over quality, customization, and after-sales support. Pre-treatment of the feed gas is essential to the long term performance and reliability of these plants. We use process simulations from licensed software to ensure complete pre-treatment.
We bring advanced 6-bed high pressure PSA technology to India’s Compressed Bio-Gas (CBG) landscape through a strategic long-term venture with Carboneum-Consult (Germany) — a name synonymous with excellence in biogas upgradation technology. This collaboration enables us to offer world-class 6-bed PSA systems, engineered for ultra-high methane recovery, industrial-grade reliability, and unparalleled operational efficiency — all custom-built in-house at GPE as per customer’s requirement with global components and local adaptability.
Pressure Swing Adsorption (PSA) is a highly selective gas separation technology used to upgrade raw biogas into high-purity biomethane (Bio-CNG). The 6-bed PSA design uses six adsorption columns operating in a staggered cyclic sequence to ensure continuous gas flow, greater recovery rates, and superior separation efficiency. Our PSA systems are equipped with high-efficiency European desiccants for deeper drying and superior adsorption, ensuring long service life and low regeneration loss.
