Products

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. The Precisive 5 gas analyzer requires no carrier-gases, no-calibration gases and offers fast-response analytics without compromising accuracy, repeatability, linearity or stability in the presence of interferences. Faster-response multi-component analysis provides significant cost-savings and efficiency gains in power-generation applications.

Description

The 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. A realtime optical analyzer capable of accurately separating the hydrocarbon components; which previously could only be performed by gas chromatograph (GC) analyzers.

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. The 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. Contact Precisive for specific requirements, compounds and ranges.

A real-time optical analyzer capable of performing compound speciation or separation; which previously could only be performed by gas chromatograph (GC) analyzers. Using a unique wavelength-sweeping tunable filter spectrometer, fast update rates down to 1-second intervals are executed for full compound speciation and detection of the customer specific compound set. Sampling is a flow-through type, suitable for a continuous, on-line, unattended operation. The analyzer does not require carrier gas, fuel gases or on-site calibration gases.

A typical system configuration provides measurements of up to the lower explosive limit (LEL) of total hydrocarbon/VOC gas with an instrument resolution of 0.1 ppm.
