Laminol® – H₂S removal
Reliable, low-pressure H₂S control that protects equipment and catalysts. Low consumables, steady low-ppm output, and simple day-to-day operation.
How It Works
Step-by-step
The Laminol process removes the hydrogen sulfide and follows several steps to regenerate the solvent.
Characterization
The stream at the inlet is first characterized in its flow rate and H2S range, so to ensure the downstream Laminol equipment is fit for purpose.
Contact and removal
A Laminol® based absorber stage is where the gas is put in contact with the solvent. As the solvent is highly selective and efficient the gas is instantly cleaned from H2S. Inline sensors check the quality of the stripped gas.
Solid sulphur removal
Solid sulphur is removed from the rich solvent using a filter or a high capacity decanter.
Solvent reactivation
Solvent is reactivated for re-use. With very low make-up rates and utility consumption, this results in predictable low overall OPEX.
Benefits
Benefits of Laminol® – H₂S removal
These benefits connect day-to-day operation to QA and cost control, because Laminol® removes H₂S at low pressure in a regenerative, recirculated loop, protecting downstream equipment and delivering a stable, spec-compliant outlet gas.
Protect downstream equipment
H₂S corrodes exchangers and valves and can poison membranes, adsorbents and catalysts. Holding sulphur and steady at low ppm prevents fouling and extends service intervals, so downstream capture and upgrading packages run as per nameplate specifications with fewer trips.
Compliance and product quality
Defined sampling at inlet and outlet of the Laminol unit plus time-aligned logs create a single evidence pack for audits and customer certificates. When a deviation occurs you can show feed composition, operating state and outlet quality for the exact window, which shortens investigations and avoids shutdown, whether the system feeds a biomethane upgrading facility, boiler or chemical plant.
Predictable OPEX
Laminol® provides low-pressure, regenerative scrubbing with a biodegradable, recirculated fluid; where duty or outlet specs require, we add lead–lag polish (e.g., dry media) to extend solvent life and catch transient spikes. Low OPEX is detemined by predictable make-up and breakthrough rates, as well as well-known utility consumption, so procurement can forecast consumption and finance sees steady month-to-month costs.
Instruments in the system keeps costs predictable: online H₂S analysers, breakthrough alarms, and fixed sampling ports feed your historian, so changeouts are planned—not reactive. Regeneration setpoints adapt to seasonal swings, and the train scales by adding vessels or polish canisters without re-engineering the core. Result: fewer emergency callouts andpredictable service windows.
Uptime and simpler operations
No time consuming and expensive activated carbon filter change-outs. Besides operators work with a small set of set points and repeatable changeout routines. As the outlet remains stable under varying inlet conditions, downstream units see fewer nuisance trips and restart faster after maintenance because ramp profiles are predictable. Shift handovers are clearer since there are fewer open issues tied to sulphur.

All frequently asked questionsWe configure outlet ppm-level targets to your specs and hold them steady with lead–lag vessels or a polish stage. That protects solvents, membranes and catalysts and stabilises downstream OPEX and uptime.
Laminol® runs at low pressure using a biodegradable, recirculated scrubbing fluid and is engineered to ride through H₂S peaks with a constant output concentration, so without pushing problems downstream.
Sulphur handling is defined with EHS up front (regeneration and disposal options), so the front-end remains robust across operating conditions.
We offer regenerative scrubbing as the core (Laminol®), with optional dry-media polish or hybrid lead–lag where duty or outlet specs require a tighter operating window. The choice depends on flow, moisture and service preferences, and is designed to meet availability and cost targets.
Hybrids add resilience to swings and simplify scheduling by catching short transients while keeping the scrubber’s OPEX predictable. We’ll propose the least-complex path that still protects capture or biogas upgrading assets.
Change on measured breakthrough, not calendar dates. Online H₂S analysis and fixed sampling points guide swap timing, which minimises downtime and consumable waste while keeping outlet quality inside limits.
Planned service windows and clear access points keep interventions quick and safe. The result is predictable OPEX and high availability for the units downstream.
