The Challenge
The Client agreed to mitigate emissions from turbine units seal gas system at one of their compression sites to satisfy an EPA consent decree regarding the Clean Air Act and the Colorado Air Pollution Prevention and Control Act. Per the terms of the agreement, the Client was required to install a seal gas capture system within 90 days of receiving the dry seal recompression unit.
The Solution
CANUSA EPC worked with the Client and packager of the dry seal recompression system to develop an engineering and design package for the installation of the system.
Multi-Discipline Engineering
- Electrical tie-in of 40 HP Motor
- PSV sizing for new relief scenarios
- Piping modeling for discharge into plant inlet to recover the gas
- Automation design to integrate with station controls
Procurement
- VFD and Cable specification
- Pressure Instrumentation
- Construction Bid Walkdowns
The Results
Deployed the first seal gas system in the fleet
- Installation of a single capture unit for seal gas of two turbine units
Reduction in fugitive methane emissions
- Reduction in venting emissions of 49.3 mton of CO2e/day
