Every Product On Spec. Every Certificate Auditable.
Refineries and petrochemical complexes operate under relentless process, quality, and regulatory pressure. LIMSera delivers AI-powered process intelligence, automated product certification, and custody transfer documentation — predicting quality deviations before they occur and optimising operations across every stream.

When Process Data And Lab Data Don't Talk, Off-Spec Product Reaches The Terminal.
Refineries and petrochemical complexes generate thousands of in-process and product samples every day. The analytical data from those samples must reach process engineers in minutes — not hours — to prevent off-spec production from propagating through conversion units and into finished product tanks. When laboratory and process systems are disconnected, by the time a quality deviation is identified in the LIMS, the process event that caused it has been running for half a shift.
Product certification adds another layer of complexity. A single product may carry different specification requirements for domestic markets, export customers, and blending purposes. CoAs assembled manually from multiple test sheets carry the risk of transcription errors, missing parameters, and incorrect limits being applied. Custody transfer disputes are expensive to resolve without tamper-evident, time-stamped analytical records.
LIMSera connects refinery laboratory data to process operations with AI-powered intelligence — predicting quality outcomes from in-process data, automating product certification, and maintaining ISO/IEC 17025-compliant analytical records that resolve commercial disputes and satisfy regulatory authorities worldwide.
Every Testing Domain Across Your Refinery Or Petrochemical Complex
Pre-configured for crude characterisation, process control, product release, and environmental compliance monitoring.
Crude Oil & Feedstock
Characterise crude oil and petrochemical feedstocks with comprehensive property suites covering API gravity, viscosity, pour point, wax content, sulphur, TAN, TBN, metals by ICP-OES, distillation profiles by ASTM D86/D1160, and SARA fractionation. LIMSera manages crude assay templates that automatically generate required test lists from feedstock classification. Referee sample management ensures split samples are preserved for dispute resolution. Feedstock variability trending alerts refinery planners when incoming crude properties deviate from contracted specifications.
The Petrochemical Testing Workflow, End To End
Sample Receipt
Samples arrive from process streams, crude tankers, or finished product tanks. Barcode or QR scanning registers the sample against process unit, stream point, product lot, and collection time. Chain-of-custody is established at receipt with sample condition and seal integrity recorded.
Sample Preparation
Preparation instructions are loaded automatically from the method library based on sample type. Homogenisation, filtration, dilution, and conditioning steps are guided and documented. Sub-samples for multiple test streams are split and logged with full traceability to the parent container.
ASTM Analysis
Tests are executed following linked ASTM, IP, or EN procedures. Instrument interfaces capture raw data automatically for densitometers, viscometers, distillation units, and XRF analysers. Manual data entry is validated against method precision requirements using repeatability and reproducibility limits.
Specification Check
Results are automatically compared to the product specification library. Multi-market variant logic applies the correct limits based on destination. Out-of-specification results trigger immediate investigation workflows with hold on product release until resolution.
Technical Review
Analysts and supervisors review results with SPC trending context. Anomalous results relative to historical process performance are flagged. Instrument calibration status and reference standard validity are verified before approval. Second-person review enforced for custody transfer samples.
Certificate Issuance
Certificates of Analysis, quality certificates, and custody transfer certificates are auto-generated on QA approval. Digital signatures applied with QR verification. Certificates are delivered to internal planning systems, customer portals, and third-party inspection agencies simultaneously.
From Crude Feedstock To Certified Product
Everything Your Refinery Laboratory Needs
ASTM / IP Method Library
Pre-loaded ASTM, IP, EN, BIS, and ISO test method library covering 500+ petrochemical parameters. Each method defines sample type, preparation requirements, instrument type, precision statements, and specification linkage. Custom methods added without coding.
Certificate of Analysis Engine
Auto-generated CoAs with product name, lot/batch number, test results, specification limits, pass/fail status, analyst attribution, QA sign-off, and laboratory accreditation details. PDF with digital signature and QR verification code.
Statistical Process Control
Real-time SPC charting for in-process and finished product streams. Shewhart X-bar and R charts, CUSUM, EWMA, and run-rule violation detection. Process capability indices (Cp, Cpk) calculated per product parameter.
Custody Transfer Certification
Quantity and quality certificates for crude oil and product cargo movements. Tank strapping integration, temperature correction, shrinkage factor application, and multi-party sign-off workflows for commercial custody transfer documentation.
Instrument Interface Management

Incident & OOS Investigation
Structured out-of-specification and out-of-trend investigation workflows with Phases I, II, and III analysis. AI-assisted root cause scoring, assignability determination, and formal investigation closure with regulatory documentation.
AI That Predicts Product Quality Before The Batch Is Complete.
LIMSera's AI engine correlates in-process parameters with finished product specifications in real time. When distillation cut-point shifts at the atmospheric tower, the AI predicts the downstream impact on flash point, sulphur, and cetane number — before the product reaches the blending header. Process engineers receive actionable alerts with the predicted quality impact and recommended corrective action, not just raw data points.
SPC charts are maintained continuously with AI-powered anomaly detection that goes beyond Western Electric rules. The machine learning model identifies multi-variable correlations invisible to univariate SPC — when a combination of feed rate, temperature, and catalyst age simultaneously shifts, the AI flags the quality risk even when individual parameters remain within limits. Every prediction is logged, tracked, and correlated with actual outcomes to improve accuracy over time.
AI Knows Your Crude Before It Reaches The Tower.
Every crude cargo is different. LIMSera's AI-powered crude assay module manages the complete characterisation workflow — SARA fractionation, distillation curves, metal content, sulphur speciation, and pour point profiles. The AI compares every incoming cargo against the historical assay database for that crude origin, identifying compositional shifts that would affect yield, product quality, or catalyst life.
When a cargo arrives with elevated metals, unusual viscosity, or wax content outside the historical envelope, the AI alerts planners with a quantified impact assessment — predicted yield shift, product quality change, and recommended processing adjustments — before the crude is pumped to tanks. Over time, the model builds a predictive understanding of how each crude origin behaves in your specific refinery configuration.
CoAs That Generate Themselves. Product Release That Happens On Time.
Petrochemical product release is a race against dispatch schedules and tanker demurrage costs. LIMSera eliminates the bottleneck of manual certificate compilation. When QA approval is given, the Certificate of Analysis is generated instantly — with product name, lot number, all test results, specification limits, pass/fail status, analyst attribution, and laboratory accreditation details. Digital signatures are applied and the certificate is delivered simultaneously to the customer portal, shipping team, and third-party inspection agency.
Multi-market variant logic ensures the correct specification is applied to every CoA without manual selection. Export certificates meet destination country regulatory format requirements automatically. For aviation fuel, JIG additive treatment records and filter monitor results are included in the certificate package. Custody transfer certificates are generated with API/ASTM volume correction calculations and multi-party sign-off workflows.
