Precision Gas Engineering & High-Yield Biomethane
At AMVATS CBG (backed by parent company Amvats Engineering & Technology), we combine thermodynamic precision with industrial automation to maximize methane recovery from diverse organic biomass. Our continuous stirred-tank digestion systems feature automated thermal regulation, enzymatic pre-conditioning, and closed-loop process stability tailored for challenging agricultural lignocellulose and industrial press mud.
Our multi-tier gas purification skids remove hydrogen sulfide (H2S), carbon dioxide (CO2), moisture, and siloxanes to yield vehicle-grade biomethane exceeding IS 16087:2016 purity standards (>96.5% CH4). Designed with closed-loop water circulation, every AMVATS CBG plant operates under Zero Liquid Discharge (ZLD) principles.
With cloud-connected PLC-SCADA architectures, operators gain real-time visibility into gas production metrics, digester volatile fatty acids (VFA/TIC), compressor pressures, and gas chromatography analysis—ensuring uninterrupted safety and maximum commercial returns.
- Integrated PLC-SCADA Automation & Real-Time Telemetry
- 3-Stage Polymeric Membrane Separation (>96.5% CH4 Purity)
- 250-Bar High-Pressure Cascade Storage & Mobile Logistics
- FCO-Certified Solid & Liquid Organic Bio-Fertilizer (FOM) Upcycling
Trusted By Leaders In Renewable Energy
Discover how our turnkey engineering, CSTR digestion efficiency, and statutory compliance empower CBG plant promoters across India.
AMVATS CBG executed our 100 TPD paddy straw CBG refinery with remarkable technical precision. Their CSTR digester design and 3-stage membrane upgrading consistently yield above 96.5% methane purity with outstanding operational reliability.
Securing PESO statutory licensing and setting up high-pressure 250-bar cascade bottling systems seemed like a massive hurdle until AMVATS CBG took charge. Their turnkey approach delivered our facility ahead of schedule and within budget.
The byproduct organic fertilizer (FOM) processing plant designed by AMVATS CBG delivers premium FCO-grade organic manure that is completely presold to regional agricultural cooperatives. A truly circular, highly profitable green enterprise.
