Precisive® 5 Hydrocarbon Composition Analyzer is an infrared absorption based on-line monitoring system configured for measurement of alkanes: methane, ethane, propane, butanes and pentanes. It is a realtime optical analyzer capable of accurately separating the hydrocarbon components; which previously could only be performed by Gas Chromatograph (GC) analyzers.
The Precisive TFS™ (Tunable Filter Spectrometer) sensor platform consists of a light source, a sample cell (for gases, liquids or solids), a wavelength separating element (spectrometer) and a photo-detector. The wavelength separating element "slices" the wavelength components of the broadband light source which then interacts with the sample molecules. Some of the wavelength components are absorbed and some are transmitted through without any absorption.
Precisive TFS™ Tunable Filter Spectrometers use an advanced spectral decomposition algorithm. The resulting spectrum is called absorption spectrum, which acts as "fingerprints" which are used to identify the sample components and/or quantify the composition of the sample.
Using a unique wavelength-sweeping tunable filter spectrometer, fast update rates down to sub-second intervals are performed for the full C1 through C5 analysis. Sampling is a flow-through type, suitable for a continuous, on-line, unattended operation. This analyzer does not require carrier gas, fuel gases, or on-site calibration gases. The standard system configuration provides measurements of up to 100% methane, 25% of ethane, 25% of propane, 10% of butanes and 5% of pentanes. Other ranges and/or additional gases are available.
