A NEW APPROACH TO HIGH CO2 MEASUREMENT - Fluenta
A NEW APPROACH TO HIGH CO2 MEASUREMENT
Reliable, real-time ultrasonic measurement for up to 100% CO₂ concentrations
The challenge of measuring high concentrations of CO₂ in flare gas has long posed risks and regulatory hurdles for the oil and gas industry. Fluenta’s FlarePhase technology brings a breakthrough solution, enabling precise and reliable measurement even in the most CO₂-rich environments.
Discover how our technology is transforming high-CO₂ measurement, backed by rigorous testing and proven industry success.
The High CO₂ Measurement Challenge
Flare gas in industrial settings, particularly in CCUS (Carbon Capture, Utilisation, and Storage) or EOR (Enhanced Oil Recovery), can often contain significant CO₂ concentrations.
High levels of CO₂ (anything over 30%) poses a unique challenge in ultrasonic flare gas measurement because CO₂ acts as a powerful absorber of ultrasonic signals, reducing their strength and compromising measurement accuracy. Traditional measurement methods struggle in high-CO₂ environments, often leading to:
- Non-compliance with regulatory standards,
- Safety risks due to unreliable data, and
- Operational inefficiencies stemming from inconsistent measurements.
With increasing regulatory demands on emissions monitoring, accurate CO₂ measurement is now an essential requirement, not an optional feature.
Adding to the challenge, CO₂’s signal absorption effect becomes even more pronounced under the fluctuating temperatures common in flare systems.
High temperatures cause a phenomenon known as Resonant Frequency Drift, where even minor temperature changes can reduce measurement efficiency. For example, a shift as small as 1 kHz (equivalent to circa 40°C which are extremely common in flare lines) can reduce the efficiency of standard transducers by around 40% leading to a substantial decrease in data accuracy.
Fluenta’s FlarePhase technology is specifically engineered to counter these effects, maintaining precision even at extreme CO₂ concentrations and across wide temperature ranges.
By adapting to both CO₂’s signal-absorbing properties and thermal fluctuations, FlarePhase offers a robust, reliable solution that ensures compliance, safety, and operational efficiency where other systems fall short.
Introducing FlarePhase: Reliable Measurement for High CO₂ Environments
Fluenta’s FlarePhase transducers are purpose-built to handle the extreme conditions of high-CO₂ flare gas systems. Key features include:
- Extended Temperature Range: FlarePhase withstands significant thermal shifts, thanks to proprietary enhanced signal processing, maintaining accuracy across extreme temperature variations.
- Frequency Stability: FlarePhase addresses resonant frequency drift, ensuring optimal signal reception and accuracy even amid frequent temperature changes.
- High CO₂ Compatibility: FlarePhase provides precise measurements at CO₂ concentrations up to 100%, overcoming the typical signal attenuation that degrades accuracy in standard systems.
- Adaptability Across Flow Rates: tested from low to high flow rates, FlarePhase consistently delivers stable data, ensuring reliability across varying flare system conditions.
With FlarePhase, operators gain reliable, real-time data that supports regulatory compliance, safety, and operational efficiency, even in the most demanding high-CO₂ environments.
