On-site, spec-consistent CO₂ for synthesis, neutralisation and utilities: audit-ready and built to scale.
How It Works
Step-by-step
Convert flue gas to a stable CO₂ utility for synthesis and plant utilities. The steps outline inlet conditioning, selective capture, specification control, buffering and optional liquefaction.
Source the CO₂ (boiler/CHP/process exhaust)
We tap CO₂-containing flue gas from boilers, CHPs or process vents and route it to the capture train. The inlet is sized to your temperature, flow and sulphur/chloride load for stable downstream operation.
Quench & condense (protect downstream assets)
Controlled quench drops temperature quickly; condenser stages remove moisture and acid vapour. Demisters reduce droplet/dust carry-over so exchangers, columns and analysers stay clean.
Capture & polish (spec for synthesis and utilities)
Galloxol® selectively absorbs CO₂ and rejects non-CO₂ gases. The product is dried and trimmed (low O₂/CH₄/particulates) for chemical uses: carbonation, pH control, methanol/e-methane routes, inerting and blanketing.
Buffer storage (smooth run/hold cycles)
Gas-phase buffering rides through start–stop sequences, changeovers and utility dips. Online analysers and auto-divert protect specification; batch-aligned logs simplify QA and audit trails.
(Optional) Liquefaction & compact inventory
When liquid CO₂ is preferred for transfer or multi-area supply, a compact skid condenses CO₂ and stores it in insulated vessels, predictable inventory with a small footprint.
Distribute to units & sites
Feed CO₂ to reactors, polishing lines and utilities, or load to tankers for nearby plants. On-site CO₂ increases resilience, reduces purchase exposure and improves schedule control.
From idea to final delivery
Our complete process at a glance
This visual guide walks you through each phase, showing how we turn concepts into results.
Yield impact
Three critical parameters in control
Hold flow, pressure and dew point inside limits and reactors behave predictably: conversion stays on track in urea/methanol routes, and neutralisation steps hit target pH without drift.
When these three stay in band, operators do fewer trims after start-ups or feed changes, rework drops, and campaign cadence is easier to keep.
Unique Selling Points
Key Advantages
When delivered CO₂ varies, conversion, pH stability and costs vary too. An on-site source turns CO₂ into a managed utility for synthesis and neutralisation, steady feeds, predictable OPEX, and controls tied to your plant systems.
Spec-consistent CO₂ at point of use
Predictable OPEX & heat-smart operation
Industrial tie-ins, interlocks & SCADA integration
Modular capacity (0.5–5 t/h per train)
Buffers + optional liquefaction for continuity
Front-end H₂S control to protect downstream assets
Benefits
Benefits for chemical producers
These are the day-to-day outcomes once CO₂ runs as an internal utility. They map to common chemical KPIs, conversion yield, neutralisation stability, uptime and audit time, across use cases like urea, carbonates/polycarbonates, methanol & syngas routes, CO₂-based solvents, pH control, CO₂-refrigerants, polyurethane foams/elastomers, and inorganic carbonates.
Continuous feed stability
A steady, dry CO₂ feed holds flow, pressure and dew point inside limits so reactors and neutralisation points behave predictably. Operators make fewer manual trims during load changes, recovery after cleaning/maintenance is faster, and nuisance alarms drop.
Stable feed conditions protect conversion and selectivity (urea/methanol, carbonates) and keep pH endpoints in band, cutting off-spec holds and smoothing campaign cadence.
For tighter control, we use cascade loops (pressure→flow), soft-ramp set-point changes after start-ups, and dew-point control via appropriately sized drying stages. Auto-changeover holds delivery when a skid is isolated, and buffer set-points are tuned to your minimum on-stream rate so brief upstream swings don’t propagate to reactors or neutralisation steps. The result is fewer trim moves, less alarm noise and steadier conversion/selectivity.
Traceable quality and easy audits
Defined sampling points, inline analysers, and clean trend logs create a verifiable record of what each unit received. Batch/campaign tags align evidence with production so QA can trace deviations quickly.
Certificates, alarms and sampling results export to QA/LIMS and your DCS/SCADA historian, shortening audit prep and helping investigations close with fewer quarantine decisions.
Traceability is designed for evidence without paperwork: time-stamped analyser trends, batch/campaign IDs carried through exports, defined calibration & sampling routines, and optional retained-sample bottles for disputes. We include a simple data dictionary (tags, units, ranges) so QA/LIMS ingestion is one-time configuration, not a recurring IT project, making audit weeks feel like any other week.
Integration with heat and utilities
Capture is matched to your heat window: High-Temp ties to steam/superheated sources for efficiency at larger duties; Low-Temp fits hot-water utilities without re-plumbing. Isolation/bypass keeps units online during works.
Buffers align with shift patterns so campaigns aren’t gated by delivery windows, and maintenance keeps familiar lock-out/tag-out routines on high-value lines.
Tie-ins are placed downstream of existing APC (e.g., ESP or wet scrubber, typically after the ID fan) so upstream reliability and permits are unaffected. Heat integration uses what you already have, steam/hot-water/hot-oil, plus sensible heat recovery where practical to keep OPEX predictable. If sulphur is present, we position H₂S pre-treat ahead of capture (lead–lag where needed) to protect solvents, membranes and catalysts downstream.
Predictable OPEX and fewer emergency buys
Internal supply reduces dependence on spot purchases and rush logistics. With a buffer (and optional liquefaction) you plan inventory around campaigns, not vendor schedules.
A visible internal baseline lets procurement buy on contracts; emergency surcharges decline and cost-per-tonne of usable CO₂ stabilises across quarters, making budgets easier to defend.
We make cost drivers visible and schedulable: energy by mode (run/regen/standby), consumables (filters/polish), and planned service kits with defined intervals. That supports a simple KPI set, £/tonne usable CO₂, % of hours on internal supply, and variance to plan, so finance sees steady profiles and procurement can buy under contracts rather than paying for last-minute logistics.
Safety and site logistics
On-site capture and compact handling reduce heavy truck movements, cylinder handling and access conflicts near process areas. Fixed routes and standard utilities simplify permits.
Replacing cage moves with fixed equipment and guards lowers risk around high-traffic corridors. Over time, fewer deliveries and clearer access paths help reduce near-miss rates.
Design follows your zoning and EHS expectations: fixed routes, labelled isolation points, relief and venting, local CO₂ detection and ventilation, and clear access for inspections. By replacing cage moves and frequent truck visits with fixed equipment and defined pads, you reduce traffic through congested corridors and make permit-to-work simpler, less time marshalling and more time producing.
Scale without retraining the plant
Start with one skid and add capacity as demand grows or new units come online. Storage or liquefaction modules bolt on without redesigning utilities.
Controls, alarms and SOPs stay consistent, so training is minimal as capacity rises; new units adopt the same sampling plan and documentation format, keeping compliance work proportional.
Capacity expands by adding trains/storage on pre-planned stubs; controls, alarms and SOPs remain the same, so training is light and documentation stays valid. Shared spares, the same HMI/DCS tags, and repeatable FAT/SAT checklists shorten projects and keep validation straightforward, your second and third expansions feel like copy-paste rather than re-engineering.

Frequently asked questions
Need more clarity?
Below you’ll find quick answers to the questions we hear most, from feed-gas limits to maintenance routines. Expand any item for details; if you don’t see your question, our engineers are one click away.
All frequently asked questionsSampling points and online analysers are time-aligned to batches or campaigns, so deviations are easy to investigate. We log pressure, temperature, dew point and key limits continuously, and surface alarms with timestamps and operator notes.
Exports drop into your QA/LIMS with minimal editing. That transparency helps process engineers correlate quality with production events, accelerating root-cause analysis and closing non-conformances faster.
We set pressure, composition and dew point to your internal limits and verify with online analysers plus fixed sampling points. This keeps synthesis feeds and neutralisation steps predictable, reducing tweak time and pH drift.
Results are logged by batch or campaign and exported to your QA/LIMS, so acceptance and investigations use the same evidence trail without extra paperwork.
Sampling ports and online analysers are time-aligned to batches/campaigns, with alarms and operator notes preserved. That makes deviations easy to locate in time and tie back to upstream events.
Exports follow your naming and frequency conventions, so QA and process engineering can correlate quality with production changes and close non-conformances faster.
If sulphur is present, yes. Front-end H₂S removal (e.g., Laminol® with optional lead–lag polish) protects membranes, cold ends and catalysts while keeping outlet ppm steady through changeouts.
This prevents downstream solvent/media surprises and simplifies permits and waste handling because the sulphur path is defined up front.
Yes. Buffers and stable conditioning keep flow, pressure and dew point within limits, even through short upstream trips. We size inventory to your minimum on-stream rate and configure auto-changeover where needed.
Continuity protects conversion and pH stability. Operators follow a short restart checklist; QA sees one uninterrupted evidence trail.
Most sites use a gaseous buffer for reactors and neutralisation; we add liquefaction when footprint is tight, transfer distances are long, or compact inventory is required. Both formats share the same quality backbone.
Switching is managed with interlocks and alarms so set-points remain stable. Inventory levels and changeover logic are visible on HMI/SCADA for proactive planning.
A priority/blending header keeps the preferred source active and changes over automatically if it dips, holding pressure to your set-points. A delivered back-up can sit behind interlocks for resilience.
Buffers are sized to ride through short disturbances and planned work. For longer events, a switchover and restart checklist protects QA evidence and unit stability.
Tie-ins and routing respect plant zoning with suitable materials, seals and isolation. We provide gas detection, ventilation guidance and relief/lock-out points, documented in the handover pack.
Sampling points are placed away from high-risk areas to reduce traffic. Clear access and labelled valves keep routine checks fast and compliant with EHS procedures.
Skids are compact with clear service access; we supply pad sizes, aisle clearances and lift points for layout review. Acoustic options keep noise within site limits.
Utilities are standard (power, cooling, steam/hot water as applicable). We confirm peak/average loads and tie-in points so Facilities can provision without surprises.
OPEX is mainly energy and consumables (filters/polish where used). Heat-smart operation and data-based changeouts keep monthly costs predictable and avoid rush buys.
Maintenance fits your windows: accessible inspection points, kitted spares and trend-guided interventions protect outlet quality while minimising downtime.
We provide clean tag lists and signals for DCS/SCADA (pressures, temperatures, dew point, alarms, states) and standard exports for QA/LIMS. Batch/campaign IDs can be passed to align records.
This keeps operators on familiar HMIs and lets QA pull evidence without manual transcription, reducing admin and audit prep time.
The system logs the parameters you need for MRV (flow, purity proxies, uptime) and can produce batch/campaign summaries. We align formats with your reporting framework.
Where credit schemes apply, data supports eligibility; actual issuance depends on programme rules and verification. The same logs serve internal ESG and external audits.
Much of the system is prefabricated. On site we complete tie-ins, prove interlocks and run performance tests against your spec.
Training covers start/stop, sampling and troubleshooting. Handover includes SOPs, alarm limits and restart checklists so the unit returns to rate quickly after maintenance.
Modules cover ~0.5–5 t/h per train; you scale by adding trains and storage without rewriting SOPs. Controls and maintenance philosophy stay consistent.
Staged growth aligns capex with demand and avoids the disruption of full platform swaps. Operators see the same screens and procedures as capacity increases.
