Compressed Biogas (CBG)
Compressed biogas (CBG) sits at the intersection of waste management, energy transition, and rural industrialization. Yet many CBG projects struggle with scale, consistency, or commercial viability — not due to a lack of technology, but because of weak design planning and poor integration of modular, utility, and process elements. At Quatech, we support CBG developers and EPC partners with execution-ready design solutions that reduce rework, accelerate time-to-site, and integrate both off-the-shelf and custom components into a unified operating system.
What’s Changing in CBG Infrastructure
- Government-backed offtake frameworks (e.g., SATAT) are driving demand — but project execution capacity is lagging
- Modular design and standardization are becoming critical for replication and scale
- Feedstock variability requires flexible gas processing designs
- Brownfield retrofits and co-location with distilleries or dairies introduce spatial and interface risks
- Increasing emphasis on H₂S removal, safety compliance, and long-term maintainability
Biogas success doesn’t stop at the digester. It’s defined by how reliably gas reaches the compression skid.”
Design Challenge - Impact on project
Design Challenge
- Gas purification technology
- Poor skid–utility integration
- Underspecified H₂S removal systems
- Raw material instability
Quatech Advantage
- Quatech works on proven and patented CO2 removal technology which ensures efficient removal along H2S removal scrubbers
- Quatech focuses on modular designs during designing stage and optimizes the layout. The interfacing is taken care in modelling using software’s from PID stage.
- Quatech works closely with the customer to understand the quality of raw material and ensures right H2S generation to size the removal system
- We design systems to accommodate multiple waste processing in turn ensuring feasibility of the plant
How Quatech Solves This
We create standardized skid-based layouts — with clear anchoring, lifting, routing, and tie-in drawings — enabling faster fabrication, better civil coordination, and repeatable replication across multiple sites.
We design for space-constrained sites by integrating process units with MCC rooms, blowers, dosing units, and utility corridors into a coherent plant layout — avoiding the common last-mile clashes that derail execution.
We engineer biogas conditioning systems with clear parameters for H₂S, moisture removal, and safety vents — helping avoid cost-cutting-induced operational pain.
We size compressors and MCCs based on actual motor load mapping, transformer capacity, and auto–manual logic — delivering a plant that operates stably, even in rural grid conditions.
Trend: Gaps between civil and MEP teams lead to slab opening mismatches, anchoring misalignments, and pipe routing rework.
Our approach treats layouts as integrated systems — using BIM-based clash detection, multi-trade drawing overlays, and coordinated pipe racks and channel routes to de-risk execution.
Trend: Plants are often designed for handover, not for a decade of operation.
We ensure that every pump, valve, and instrument is accessible, maintainable, and clearly documented. Backwash loops, chemical dosing points, and sludge lines are placed with operator input and lifecycle logic — not just engineering symmetry.
We specialize in brownfield overlays — using digital tools like scan-to-model and clash detection to retrofit CBG units into distilleries, dairies, or ETPs without disrupting existing operations.
We produce drawings, BOQs, and documentation that support not just buildout, but handover — including SOP integration, loop diagrams, and remote monitoring enablement.
