Natural Gas Quality, C1-nC6 Hydrocarbon Composition, and BTU/Wobbe Monitoring with Tunable Filter Spectroscopy
The MKS Precisive® product platform of optical analyzers based on Tunable Filter Spectroscopy (TFS™) provides real-time gas analysis in the natural gas and hydrocarbon processing industries, including refineries, hydrocarbon processing plants, gas-to-power machines, biogas processes and fuel gas transportation and metering, while delivering customers a substantially lower total cost of ownership.
Tunable Filter Spectroscopy from UV (Ultra-Violet) through IR
Precisive® TFS™ can be utilized from UV (Ultra-Violet) through IR (Infra-Red) spectral regions. The Precisive® TFS™ sensor platform has been on the market since 2008 with more than 2500 systems deployed.
Precisive® optical sensors are the first widely deployed hydrocarbon composition monitors to feature real-time unattended analytics with hydrocarbon speciation capability equivalent to traditional Gas Chromatography (GC) instruments yet, with much lower cost of ownership.
Now a part of MKS Instruments, the Precisive® TFS™ sensor platform will be further developed for trace/ppm through bulk/% applications where a multi-component, low-maintenance, stable analytical sensor-transmitter is required that is well positioned between traditional NDIR (Non-Dispersive Infrared) and laboratory-grade FTIR (Fourier Transform Infrared).
Precisive® 5 Hydrocarbon Analyzers
The predominant measurement technique until now has been Gas Chromatography (GC) given the ability to separate individual compounds with high selectivity, albeit its slow response and high infrastructure requirements. For faster measurement requiring only a single heating value measurement, residual oxygen calorimetry is often used. Precisive® 5 gas analyzers require no carrier-gases, no-calibration gases and offer fast response analytics without compromising accuracy, repeatability, linearity or stability in the presence of interference. Precisive 5's faster-response multi-component analysis provides significant cost-savings and efficiency gains in power generation applications.
