On-Demand Webinar:

Oil & Gas Technology

Date: June 4, 2014
Time: 1 PM EDT (10 AM PDT / 7:30 PM CEST)
Duration: 1 hour

Overview

Measuring the flow of flare gas and calculating the mass of carbon flared is difficult due to the changing environment inside a flare stack. Conditions vary from the low velocities of normal operation to gas velocities exceeding 100 m/s during blow-down. Attendees of this presentation will examine the challenges of flare gas measurement and explore methods and practices currently used by industry. These include calculation-based methods which require knowledge of the process equipment, to direct measurement methods using a single flare meter or distributed array of sensors. The presentation will also address uncertainty factors as well as common errors encountered during measurement. In the end, participants will gain a better understanding of why flare gas measurement is important, how difficult the measurement challenge is, and best practices for accurate measurement.

Key Takeaways

  • Learn why flare gas measurement is important
  • Understand how difficult measurement conditions are in a flare stack
  • Discover available methods for flare gas measurement
  • Anticipate expected measurement uncertainties
