In situ zirconia-based O2 analyzer for high-temperature and SO2/SO3 gas environments

Overview

RB Technologies offers an advanced in situ zirconia-based O2 analyzer specifically engineered for challenging high-temperature and sulfur-rich gas environments. Building on a proven TRL9 zirconia-based O2 sensor, this solution incorporates SOx-resistant coatings and catalytic layers to protect sensing electrodes. With its compact design, the sensor is easy to integrate and maintain, providing a robust solution for industries requiring precise oxygen measurement in harsh conditions.

Technical specifications

• Zirconia-based sensing technology: Utilizes the Nernst equation to measure oxygen partial pressure.
• SOx-resistant coatings: Protects the sensor in environments with high sulfur oxide concentrations, typical in smelter off-gas.
• Catalytic protective layers: Enhances electrode protection and operational stability.
• High-temperature operation: Effective up to 1,000°C, suitable for furnace conditions.
• Compact design: Facilitates easy integration and maintenance in existing industrial systems.

Technology readiness level

The technology is currently at TRL 5, having been validated in industry settings with sulfur concentrations below the target threshold. Initial field testing in real process environments is planned to assess performance and durability, followed by laboratory optimization to refine sensor design. Collaboration for data access and integration support is sought to accelerate development.
