Hybrisol® – Biogas upgrading
Upgrade biogas to grid-quality biomethane, robust to Ammonia (NH₃), Volatile Organic Compounds (VOCs) and terpenes, with ultra-low methane slip.
How It Works
Step-by-step
Laminol® removes H₂S, Hybrisol® absorbs CO₂, water, NH₃, VOCs mercaptans and terpenes, the regenerator releases clean CO₂, and a small polish finalizes grid-quality biomethane.
Characterization
We characterize the raw biogas in flow, CH₄/CO₂ ratio, H₂S, NH₃, VOCs/terpenes, moisture, temperature/pressure. This lets us adjust the process parameters downstream to align the biomethane production spec with your grid/buyer limits.
Protect & condition (H₂S)
Low-pressure H₂S removal. If sulphur is present, Laminol® removes H₂S at low pressure using a biodegradable scrubbing fluid that’s re-used. It rides through H₂S peaks, cutting corrosion and protecting solvents, membranes, and cold ends in the downstream biogas purification train.
Absorption (Hybrisol®)
Hybrisol® applies absorption to remove CO₂, co-removing NH₃, VOCs and terpenes, and dry the gas. Because capture is chemistry-driven, performance stays stable through day-to-day feed swings.
Outcome: grid-quality biomethane with ultra-low methane slip and a low dew point.
Regenerate & recover (CO₂)
The solvent is regenerated in a closed loop with efficient heat recovery, keeping operating cost predictable and minimizing losses. The co-product is a clean CO₂ stream that can be buffered or routed to storage/liquefaction depending on your site’s plan.
That CO₂ can support horticulture, beverages, or e-fuel routes, or sit as future upside.
Meter, QA, inject
Online analyzers (CH₄/CO₂, dew point, O₂), fixed sampling points, and calibrated meters produce a single certificate pack for buyer or grid acceptance.
All instruments alarm to your DCS/SCADA with clear data for export, ensuring biomethane production remains both auditable and hands-off for operators.

Chemistry that handles Ammonia/Volatile Organic Compounds (VOCs)/terpenes
Hybrisol®’s liquid phase absorbs CO2, Ammonia (NH₃) and co-captures Volatile Organic Compounds (VOCs), mercaptans, carbonyl sulfide, and terpenes to the design limit, so you avoid oversizing upstream carbon beds and frequent changeouts. That tolerance is a key difference to membrane systems, which typically need those species removed before separation.
Low dew-point biomethane
Absorption removes both CO₂ and H₂O; field data show water content can be driven very low, which trims or eliminates downstream refrigeration dryers.
Less flare, lower CH₄ losses
Hybrisol® targets low methane slip in the main step, rather than recovering it later. This means no methane recovery step is required and no methane is lost by flaring.
Simpler pre-treat, smaller plot
With membranes/PSA, you often need extensive pre-treatment (water, ammonia, siloxanes, H₂S, VOCs) modules to reach spec. Hybrisol® removes CO₂ and handles key contaminants in one absorber, shrinking the pre-treat footprint and CAPEX.
Modular capacity for growth
Hybrisol® is delivered in modules sized to your flow rate and turndown; parallel trains add capacity without disrupting operating practices. Comparative CAPEX scaling charts help select the best layout for your size range.

All frequently asked questionsShort answer: No. Hybrisol®’s absorption chemistry neutralises/removes NH₃ in the liquid phase, so normal NH₃ swings don’t push you off spec. By contrast, membrane trains typically require ammonia removal upstream to protect membranes and limit slip. This is a major reason Hybrisol® keeps pre-treat right-sized.
Not typically. Because Hybrisol® co-handles VOCs and terpenes inside the absorber and is tolerant to variation, upstream polishing is tailored to your case. Often not needed or if needed it can run with fewer changeouts and lower consumables over the year. This is based on experience across different industry but each application should be carefully considered before full scale deployment.
Absorption removes H₂O with CO₂, delivering a low dew point stream. In comparable absorption schemes, water can be reduced to trace levels, which often minimises or removes the need for a separate refrigeration dryer. Your final dryer choice depends on grid spec and climate, but the absorber already does most of the drying work.
Hybrisol® targets low slip in the main step. Membranes and PSA frequently show medium/high slip, then add modules to recover it. That extra recovery hardware increases complexity and can raise OPEX. Hybrisol®’s approach keeps product in the pipeline and reduces flare hours.
Yes, modules are sized to duty, with parallel trains for expansion and turn-down. Comparative CAPEX scaling helps pick the right layout for 250–1000+ Nm³/h classes and beyond; we engineer to your spec, utilities and footprint.
