Sierra's new Real-Time Flare Measurement System
09 June 2021
Sierra’s QuadraTherm® qMix RealTime Flare Measurement System (FMS) delivers real-time flare gas flow measurement to accurately measure flows down to 0.1 sfps, meeting the full range of EPA regulations. For the first time with thermal technology, flow rate accuracy adjusts to flare gas composition changes within seconds to match real-time readings from a gas chromatograph—retaining accuracy without factory recalibration. The technology will help plant engineers to comply with EPA Refinery Sector Rule 40 CFR 63 rule which requires refineries to measure and report flare gas measurement at flow rates as low as 0.1 fps (0.03 mps).
The qMix RealTime FMS integrates with your current compositional gas sampling device or a gas chromatograph to give accurate flows over a large turndown. When the gas composition changes, the qMix RealTime App, loaded onto the supplied laptop or computer, reads the outputs from a gas chromatograph for updated flare gas composition. qMix RealTime creates a new gas composition to match the gas chromatograph composition and automatically updates the 640i/780i thermal mass flow meter to adjust the flow rate to account for its new gas composition.
