Carbon Capture Inspection and Solvent Tank Monitoring – Why Rugged Tablets Are Replacing Paper Logs

By HOTUS Technology | Updated May 2026

Carbon capture, utilization, and storage (CCUS) is moving from pilot scale to industrial deployment. Large-scale projects are being commissioned across power generation, cement, steel, and chemical sectors. Policy incentives such as tax credits and decarbonization funding are accelerating this transition, pushing operators to scale faster while maintaining strict compliance standards.

Behind the headlines, day-to-day operations rely heavily on solvent-based CO₂ capture systems. Amine loops, absorber columns, and regeneration units require continuous inspection and precise monitoring to maintain performance and safety.

Challenges in Amine System Inspection and Data Collection

Solvent-based capture systems introduce several operational challenges:

• Chemically aggressive environments that damage traditional paper logs
• Frequent manual inspections of pH, temperature, and contamination levels
• High risk of missing or incomplete data entries
• Limited ability to track long-term solvent degradation trends

Paper-based recording methods fail quickly in these conditions. Exposure to amine solutions, humidity, and handling leads to data loss and illegible records, making audits and performance analysis difficult.

Rugged Tablet Solution for CCUS Field Operations

The Hotus ST11-M rugged tablet is engineered for chemical processing environments. Its sealed enclosure resists exposure to solvents and allows for routine cleaning without affecting performance.

Operators can complete inspection routines directly on the device, including:

• Recording solvent pH and temperature readings
• Logging tank levels and visual inspection notes
• Capturing images of equipment conditions
• Validating corrosion monitoring checkpoints

Each entry is automatically timestamped and linked to the inspection location, ensuring traceability across all operations. Built-in validation rules prevent incomplete submissions, reducing human error during routine checks.

Running on a full Windows operating system, the ST11-M integrates directly with plant management software, eliminating the need for data transcription or secondary input processes.

Material Traceability with RFID and Barcode Integration

The Hotus F502 industrial PDA supports RFID and barcode scanning for full lifecycle tracking of consumables used in CCUS operations.

This includes:

• Amine solvent batches
• Filtration components
• Corrosion inhibitors
• Maintenance spare parts

By linking material usage to specific equipment and timeframes, operators gain complete visibility into process inputs. This is critical when diagnosing system performance issues or preparing compliance documentation.

Real-Time Monitoring and Decision Support

For supervisory and engineering teams, the Hotus ST13-J rugged tablet provides a centralized view of plant conditions. Data collected from field devices is aggregated into dashboards that highlight trends and anomalies.

Engineers can monitor:

• Corrosion rate variations
• Solvent degradation patterns
• Capture efficiency metrics
• Inspection compliance status

Early detection of abnormal trends allows maintenance teams to act before issues escalate into equipment failures or production losses.

Benefits of Digitalizing CCUS Inspection Workflows

Facilities adopting digital inspection systems report measurable improvements in both compliance and operational efficiency:

• Near-complete inspection data capture
• Improved audit readiness and regulatory compliance
• Reduced unplanned downtime
• Enhanced process transparency and reporting accuracy

Digital workflows transform inspection data into actionable insights, supporting long-term optimization of carbon capture performance.

Conclusion: Building Reliable Data Infrastructure for Carbon Capture

As CCUS facilities expand, the need for reliable, verifiable data becomes critical. Inspection processes must evolve to match the scale and complexity of modern carbon capture operations.

Replacing paper-based methods with rugged, connected devices ensures that every measurement is recorded, every asset is tracked, and every compliance requirement is met with confidence.
