H₂S Removal & Biogas Purification System
The H₂S Removal System is an essential component in BIO-CBG and industrial biogas plants, designed to eliminate corrosive sulfur compounds from biogas before further utilization and processing. Efficient hydrogen sulfide removal improves gas quality, enhances operational safety, protects plant equipment, and increases the overall lifespan of critical systems.
Water Scrubber Technology for Biogas Upgradation
Water Scrubber technology is a highly efficient biogas upgradation solution used to increase methane purity by separating unwanted gas components through a controlled absorption process. Using water as a natural scrubbing medium, this system offers an eco-friendly, reliable, and cost-effective method for improving biogas quality.
GRELIANCE integrates advanced water scrubber systems into BIO-CBG and industrial biogas projects to deliver high-purity upgraded gas suitable for compression, bottling, and commercial applications.
PSA Purification System
The PSA (Pressure Swing Adsorption) Purification System is an advanced biogas upgradation technology used to produce high-purity BIO-CBG by efficiently separating unwanted gas components through controlled pressure-based adsorption cycles. This process enables enhanced methane concentration while maintaining stable and consistent gas quality.
Amine scrubber system
The Amine Scrubber System is a highly efficient biogas purification technology used to remove carbon dioxide (CO₂) and hydrogen sulfide (H₂S) from biogas, resulting in high-purity BIO-CBG suitable for commercial and industrial applications. This advanced process uses specialized amine solutions to selectively absorb unwanted gases while maximizing methane recovery and overall gas quality.
MSW-Based BIO-CBG Plant Solutions
MSW-based BIO-CBG plants convert municipal solid waste into clean, renewable compressed biogas and nutrient-rich organic fertilizers through an integrated waste-to-energy process. By combining waste segregation, anaerobic digestion, and advanced gas purification technologies, GRELIANCE delivers sustainable solutions for efficient urban waste management and renewable energy generation.
