A biogas CHP engine running on gas with 450 ppm H2S instead of the safe 150 ppm limit is accumulating sulfuric acid in lubricating oil at three times the normal rate — corroding cylinder liners, degrading piston rings, and building toward a catastrophic engine failure that costs €80,000–€200,000 in parts and 6–10 weeks of lost generation revenue. The operators don't know the H2S has spiked because the gas analyser data sits in a SCADA screen that nobody is watching at 3am on a Saturday. When the CHP trips on engine fault the following Monday morning, the damage is already done. iFactory continuously monitors CH4%, CO2%, H2S, O2, and NH3 concentrations from every gas analyser connected to your biogas network — running AI anomaly detection on the full composition profile, generating mobile alerts within 90 seconds of a quality deviation, and automatically correlating composition shifts with upstream digester biology to identify the root cause before the CHP is exposed to out-of-specification gas. Book a demo to see gas composition monitoring configured for your plant's analyser network.
Quick Answer
iFactory integrates with every gas analyser in your biogas network — inline process analysers, portable spot-check instruments, and biomethane grid injection quality sensors — delivering real-time CH4, CO2, H2S, O2, and NH3 monitoring with AI-powered anomaly detection, mobile alerts within 90 seconds of specification breach, automatic root cause correlation with upstream digester biology, and CHP protection logic that flags unsafe gas quality before engine damage occurs. Average result: 94% reduction in undetected H2S exceedance events, €120,000+ annual CHP maintenance cost avoidance per engine.
How iFactory Converts Raw Analyser Data Into CHP Protection Intelligence
The pipeline below shows the six-stage process iFactory applies continuously — from gas analyser data ingestion to root cause identification and corrective intervention — protecting your CHP engine and biomethane yield simultaneously.
1
Multi-Analyser Integration — All Gas Points
Real-time ingestion from all connected gas analysers — inline process analysers (Sick, Bühler, Perma-Pipe), portable measurement imports, SCADA historian feeds, and biomethane quality meters — via OPC-UA, Modbus, MQTT, or API. No analyser left unmonitored.
CHP gas supply: CH4 62.1%, CO2 34.8%, H2S 287 ppm (↑ rising), O2 0.04%, NH3 18 ppm. Digester 2 outlet: H2S 612 ppm. Mixing header: H2S 287 ppm (Digester 2 contribution 68%).
2
AI Composition Trend Analysis
Machine learning models analyse the full composition profile — not just individual parameter thresholds. Identifies multivariate quality shifts: rising H2S with stable CH4 indicates substrate change; falling CH4 with rising CO2 indicates biological stress; O2 intrusion with dropping CH4 indicates gas handling leak.
3
Root Cause Correlation — Digester Biology Link
AI cross-references gas composition deviations with upstream digester biology — substrate composition changes, VFA levels, pH trends, sulfate-rich feedstock additions — to identify the biological or operational root cause driving the composition shift.
4
Alert Generation — 90-Second Mobile Delivery
Mobile alert pushed to plant manager, CHP operator, and maintenance team within 90 seconds of anomaly detection — with current reading, trend rate, time-to-limit estimate, root cause, and recommended action. No alarm board polling required.
5
CHP Protection Logic & Intervention Recommendation
Engine protection logic calculates safe operating window — time remaining before H2S or CH4 deviation risks CHP damage. Intervention recommendations generated: iron dosing rate, substrate dilution, FeSO4 dosing pause, or H2S scrubber check. Shutdown recommendation if limit breach imminent.
6
Intervention Tracking & Compliance Logging
Intervention actions logged with timestamp and operator ID. Gas composition recovery tracked in real-time against prediction. Continuous compliance log generated for biomethane grid injection quality requirements and CHP engine OEM maintenance records.
Alert GC-2841 resolved. FeSO4 dosing increased at 14:22. H2S peaked at 318 ppm at 16:40, declining. CHP limit (400 ppm) not exceeded. Compliance log updated. Engine oil analysis schedule maintained.

Gas Parameters iFactory Monitors — and What Each Deviation Means
Every card below represents a critical gas quality parameter, the biological or operational mechanism that drives its deviation, the damage it causes to CHP or grid injection equipment, and how iFactory detects and responds to it before damage occurs. Talk to an expert about your current gas quality monitoring gaps.
CH₄
Methane Content — Yield and Energy Value
Normal range: 52–70% for mixed agricultural substrate. Biomethane grid injection: ≥96% after upgrading.
Deviation mechanisms: Falling CH4 with rising CO2 indicates biological stress — methanogen inhibition from VFA accumulation, ammonia toxicity, or temperature drop. CO2 enrichment also lowers energy content below CHP manufacturer specification. Rapid CH4 drop (>3% in 24h) is a biological crisis indicator.
iFactory response: Correlates CH4 decline with upstream biology — VFA, pH, OLR — identifies the inhibition source and generates upstream digester intervention recommendation before gas quality requires CHP derating.

H₂S
Hydrogen Sulfide — CHP Engine Killer
Normal range: <200 ppm for sensitive CHP engines; <500 ppm for robust configurations. Biomethane grid injection: <5 mg/m³.
Deviation mechanisms: Sulfate-rich substrates (slaughterhouse effluent, poultry litter, certain silages) increase sulfate-reducing bacteria activity. H2S in combustion gas forms sulfuric acid, corroding cylinder liners, bearings, and lubrication oil at 3–5× the rate of clean gas. A single 24-hour H2S spike above 800 ppm can reduce engine oil change interval from 500 to 200 hours.
iFactory response: Tracks H2S trend rate, projects time-to-limit with 95% accuracy, correlates with substrate sulfate content, recommends FeSO4 dosing adjustment, scrubber efficiency check, or substrate dilution — all before limit breach.

O₂
Oxygen Content — Explosion Risk and Anaerobic Integrity
Normal range: <0.5%. Biomethane grid injection: <0.5%. Above 1% with CH4 present creates explosive mixture risk.
Deviation mechanisms: Air ingress through damaged membranes, cover seal failures, agitator shaft seals, or gas handling leaks. O2 presence inhibits strict anaerobes — methanogen activity decreases, VFA accumulation follows. In gas handling, O2 + H2S creates sulfuric acid at elevated rate. Explosion risk increases exponentially above 2% O2.
iFactory response: Any O2 reading above 0.3% triggers immediate high-priority alert — O2 intrusion is categorised as safety-critical, not just a quality deviation. Root cause analysis cross-references with gas system pressure monitoring to identify intrusion point location.

CO₂
Carbon Dioxide — Energy Content and Upgrading Efficiency
Normal range: 28–48% in raw biogas. Rising CO2 with falling CH4 is the primary indicator of biological stress.
Deviation mechanisms: CO2 increase indicates methanogenic step inhibition — acidogens continue producing CO2 but methanogens cannot convert it to CH4. CO2 also affects upgrading system performance — pressure swing adsorption (PSA) and membrane upgraders are sized for specific CO2 ranges; unexpected enrichment above design spec increases methane slip and upgrading cost. Dissolved CO2 in digestate also affects post-processing and fertiliser pH.
iFactory response: Monitors CH4:CO2 ratio as a primary biological health indicator. Rising ratio triggers upstream digester investigation — identifying inhibition cause before CH4 content falls below CHP minimum specification or upgrading system operating range.

NH₃
Ammonia in Biogas — Combustion Contamination
Normal range: <100 ppm. Jenbacher and MWM engines: manufacturer limit typically <50 ppm.
Deviation mechanisms: High-protein substrates (slaughterhouse waste, poultry litter, sewage sludge) release ammonia during anaerobic degradation — ammonia partitions between digestate liquid and biogas phase. In combustion, NH3 forms NOx emissions that breach environmental permit limits and cause catalyst degradation in CHP engine exhaust after-treatment systems. NH3 in biogas also indicates high liquid-phase ammonia — a potential methanogen inhibitor.
iFactory response: Monitors NH3 trend correlated with nitrogen-rich substrate additions. Alerts when NH3 approaches CHP specification limit, recommends substrate C:N ratio adjustment, and flags for NOx emissions compliance review.

Siloxanes
Siloxanes — Turbine and Engine Abrasive Damage
Normal range: <1 mg/m³ total siloxanes for most CHP engines; <0.1 mg/m³ for gas turbines.
Deviation mechanisms: Municipal sewage sludge digesters receive siloxanes from personal care products and industrial waste. In combustion, siloxanes oxidise to crystalline silica (SiO2) — microscopically hard particles that abrade cylinder walls, pistons, and valve seats. Siloxane damage is insidious: cumulative, invisible during operation, and only detected at major overhaul when €60,000–€180,000 in engine damage is already done.
iFactory response: Integrates periodic siloxane lab analysis with operational data — correlating siloxane load with substrate composition changes. Flags increased siloxane risk from new sewage sludge batches, recommends activated carbon filter replacement schedule, tracks filter breakthrough indicators.

H2S Scrubber Performance Monitoring — Protecting the Protection System
An H2S scrubber that has lost effectiveness is more dangerous than no scrubber — because operators believe the gas is clean when it isn't. iFactory monitors scrubber performance continuously, detecting biological iron bed exhaustion, FeSO4 dosing failures, and bypass leaks before H2S reaches the CHP engine.
Scrubber Inlet vs Outlet Differential
Continuous differential monitoring between analyser upstream and downstream of H2S scrubber — tracking removal efficiency in real time. When efficiency drops below 85%, alert generated before outlet H2S approaches CHP limit. Iron bed regeneration or replacement scheduled proactively.
FeSO4 Dosing Rate Tracking
Monitors FeSO4 dosing pump performance — flow rate, dose volume per day, and correlation with in-digester H2S generation rate. Detects pump failures, blocked dosing lines, and under-dosing before H2S breakthrough occurs. Calculates optimal dosing rate from inlet H2S load and scrubber bed capacity.
Iron Bed Capacity Prediction
AI calculates cumulative H2S load against scrubber media capacity — predicting iron bed exhaustion date with 14-day advance warning. Replacement scheduling integrated with work order management. No more unexpected breakthrough events that force emergency CHP shutdown for scrubber servicing.
Biological H2S Scrubbing Efficiency
For biological H2S scrubbers, monitors air injection ratio, biosulfur formation rate, and scrubber pH — detecting nutrient depletion, bacterial population stress, or air supply failures before scrubber effectiveness collapses. Correlates scrubber biology with in-digester H2S trends for coordinated management.

Biomethane Grid Injection — Gas Quality Compliance Monitoring
Plants upgrading biogas to biomethane for grid injection operate under the strictest gas quality specifications — Wobbe Index, CH4 purity, H2S, O2, CO2, water dew point, and total hydrocarbons must all remain within network operator specification simultaneously. A single parameter exceedance can trigger a grid disconnection notice with 24-hour response requirement.
Wobbe Index Continuous Calculation
Real-time Wobbe Index calculated from CH4, CO2, and N2 composition — tracking against network operator upper and lower calorific value specification. Alerts when Wobbe Index trends toward specification boundary before the gas quality meter at the grid interface detects a breach. Protects against grid disconnection and penalty clauses.
Upgrading System Performance Correlation
Correlates raw biogas composition with upgrading system performance — PSA, membrane, or water scrubbing efficiency monitored against raw gas CH4 and CO2 input. Detects upgrading efficiency degradation from molecular sieve saturation, membrane fouling, or compressor performance before CH4 purity at grid injection point falls below specification.
Regulatory Compliance Documentation
Continuous gas quality compliance log with timestamped records for every measured parameter — exportable for network operator annual reporting, EU Renewable Energy Directive (RED II) biomethane sustainability documentation, UK GGSS (Green Gas Support Scheme) metering evidence, and insurance audit requirements. Compliance package generated in under 5 minutes for any date range.
Odorisation and Calorific Value Tracking
Monitors odorisation system performance and THT (tetrahydrothiophene) dosing rate — detecting under-odorisation that creates safety compliance risk and over-odorisation that contaminates gas handling equipment. Calorific value calculated continuously from composition and correlated with grid tariff calculations for revenue verification.

From the Field
"We had our second Jenbacher engine overhaul in three years — €140,000 each time, primarily from cylinder liner corrosion we attributed to H2S exposure. Our SCADA showed daily gas readings but nobody was tracking trends at night or over weekends. After deploying iFactory, we received an H2S trending alert at 2:17am on a Sunday — the system identified that a new batch of poultry effluent in Digester 3 was driving it and recommended increasing FeSO4 dosing. We did it remotely via the SCADA interface by 2:45am. The H2S peaked at 310 ppm and came back down without ever reaching our 400 ppm CHP limit. That was nine months ago. We haven't had an H2S exceedance since deployment. The platform paid for three years of licensing in the first engine damage event it prevented."

Frequently Asked Questions
QWhich gas analysers does iFactory integrate with — do we need specific hardware?
iFactory integrates with any gas analyser that outputs data via Modbus TCP/RTU, OPC-UA, MQTT, or RS-232/485 serial — including Sick FLOWSIC, Bühler Technology, Perma-Pipe gas monitors, Dräger systems, ABB analysers, and custom SCADA historian feeds. No hardware replacement required. For plants without continuous online analysers, periodic lab analysis import via CSV is also supported — iFactory models the composition between measurements using operational interpolation. Book a scoping call to confirm compatibility with your analyser setup.
QHow does iFactory identify which digester is the source of a gas quality deviation when multiple digesters feed a common gas header?
iFactory uses analyser data from each digester outlet — where available — combined with flow-weighted mixing calculations to attribute gas quality at the common header back to individual digester contributions. When per-digester outlet analysers are not installed, the system uses biological parameter correlation (VFA, substrate composition, sulfate load) from each digester to calculate the most probable source. Root cause attribution accuracy above 87% with flow and biological data combined.
QCan iFactory integrate with our CHP engine management system to automatically derate or shut down on gas quality alerts?
iFactory provides alert and recommendation outputs — it does not write directly to CHP engine control systems by design, maintaining OT network security and ensuring human oversight of engine management decisions. However, iFactory can send structured alerts to your CHP SCADA or BMS system via API, enabling operator-approved automatic responses. Integration with Jenbacher JMB, MWM TCG SCADA, and Caterpillar CHP management systems via read-only and alert-output configurations is available. Discuss your CHP integration requirements in a demo.
QWhat is the ROI case for gas composition monitoring versus continuing with periodic manual checks?
A single H2S-caused Jenbacher or MWM engine overhaul costs €80,000–€200,000 in parts plus 6–10 weeks of lost generation at 3.2 MW average = €180,000–€420,000 revenue loss. A single prevented overhaul recovers 3–5 years of iFactory platform cost. Additional ROI from: biomethane grid disconnection penalties avoided (€15,000–€50,000 per incident), CHP oil change interval extension from 300 to 500 hours = €8,000–€15,000 annual lubricant saving per engine, and feed-in tariff maximisation through continuous CH4 quality verification. Book a demo to build your plant-specific ROI model.
