Summary
On-line analytical methods involve extracting a sample from a process system via an automatic sampling system and analysing it continuously with a field installed analyser system.
How it Works
On-line analyser systems are widely used methods to determine gas compositions on most oil and gas operating facilities. These systems will cover a variety of applications with different types of analysers.
On-line analysis methods that can be used on flare systems, are as follows, but not limited to:
These systems operate continuously, and provide regular updates to the operating system, up to every fifteen (15) minutes. These results are then utilised within the operating system to provide continuous emissions results. These systems are often required to be installed to satisfy regulatory or operating agreement requirements.
Regular calibration is required for these on-line analytical systems to maintain their accuracy.
On-line analysis is widely used in the Oil and Gas Industry.
