Using Seeq and PI to measure and reduce Compressor Blowdowns

Nicholas Galizia, Sr. Engineer and Matthew Whiteman, Technical Architect, Equitrans Midstream

Accurate measurement and reporting of methane emissions from natural gas compressor operations is a critical function. Learn how Equitrans Midstream shifted automated compressor blowdown calculations using Seeq. These calculations utilize Seeq’s formula functions and asset capabilities (including PI-AF) to scale calculations across the fleet of ~200 compressors. The results are then written back to PI for standard reporting and to utilize event frame notifications. This methodology has enabled streamlined reporting and rapid validation of process improvements.
