Precisive is a high-growth, global, process & pipeline instrumentation company in fuel gas analysis markets. We offer new (and disruptive) sensor technologies for on-line bulk/% process & trace/ppm impurity monitoring which are the preferred alternatives to traditional Gas Chromatography (ie GC-TCD).
Precisive Applications
Precisive is focused on the oil & gas markets for a variety of natural gas and hydrocarbon processing applications. From upstream gas processing, to mid-stream distribution and down-stream refining and power generation. The unique Precisive TFS platform further lends itself to a diverse set of monitoring points from bulk high percentage level compositions, fast-response bulk BTU and Wobbe Index monitoring, through to trace ppm (part per million) trace impurity in natural gas, refinery gas and ambient air conditions.
Technique
The Precisive TFS sensor platform consists of a light source, a sample cell (for gases, liquids or solids), a wavelength separating element (spectrometer) and a photo-detector, as depicted in Figure 1. A 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. The resulting spectrum is called absorption spectrum (Figure 2), which acts as “fingerprints” which can then be used to identify the sample components and/or quantify the composition of the sample.
