Measuring CO2 in Natural Gas: Device Needed

In summary, the conversation is about finding a device that can measure the percentage of CO2 in natural gas in real time, with a resolution of 0.1%, at high pressure and temperature. The suggestion of using a gas chromatograph is given, but it is noted that it may not have a fast enough response time. The link to a company that specializes in gas sensors is provided as an alternative option.

Does anyone know of a device that will measure the percentage of CO2 (about 5% and resolution down to 0.1%) in natural gas, in real time, the gas is at approx 40 bar and 30 Deg C.
Thank you

No, we have a gas chromatograph but the response is too slow, I'm trying to catch a rise in CO2 that is faster then the chromatograph will see.

Thanks Ivan I'll contact them.
 

1. How is CO2 measured in natural gas?

CO2 in natural gas can be measured using a device called a gas analyzer. This device works by using infrared spectroscopy to detect and quantify the amount of CO2 present in the gas sample.

2. What is the importance of measuring CO2 in natural gas?

Measuring CO2 in natural gas is important for various reasons. Firstly, it allows for the determination of the quality and purity of the gas, which is crucial for safety and efficiency purposes. Additionally, it helps in identifying potential issues with the gas source, such as contamination or leaks. Finally, accurate CO2 measurements are necessary for compliance with regulations and standards.

3. Can any device be used to measure CO2 in natural gas?

No, not all devices are suitable for measuring CO2 in natural gas. Gas analyzers specifically designed for this purpose should be used to ensure accurate and reliable results. These devices are calibrated and optimized for measuring CO2 in natural gas samples, making them the most appropriate choice for this task.

4. How often should CO2 in natural gas be measured?

The frequency of CO2 measurements in natural gas can vary depending on the specific needs and requirements of each situation. However, it is recommended to regularly monitor CO2 levels to ensure the safety and quality of the gas. This can be done daily, weekly, or monthly, depending on the application.

5. Is it possible to measure CO2 in natural gas without a device?

No, measuring CO2 in natural gas requires the use of a specialized device. While some other methods, such as titration or chromatography, can also measure CO2, gas analyzers are the most accurate and efficient option for this specific task.
