TFS Hydrocarbon Composition Analyzer
Brand: Envent Engineering LtdThe TFS offers a multi-component gas analysis at unparalleled speed. The standard Envent TFS measures methane, ethane, propane, iso-butane, iso-pentane and a combined measurement for (n-butane, n-pentane and n-hexane), as well as percent level CO2 and H2S.
The spectrometer utilizes a tunable Fabry-Perot assembly that provides wavelength scanning along with advanced spectral processing that can produce response times as fast as 1 to 10 seconds.
Additional measurement options are available depending on the application. This includes component analysis for the Hydrocarbon Processing Industry such as ethylene, propylenes, and butenes.
Sampling is with a flow- through cell, suitable for continuous, online, unattended operation. The analyzer does not require carrier gas, fuel gas or on-site calibration gas.
The standard Envent system configuration provides measurements of up to 100% methane, 25% ethane, 25% propane, 10% butanes and 10% pentanes, 100% H2S and 100% CO2. Diatomic compounds such as nitrogen, oxygen and hydrogen are not measured directly and are combined and reported as one group of unmeasured inert gases.
