The objective of the project is to reduce greenhouse gas emissions from up to 15 natural gas processing and compression facilities owned by Encana Corporation. The project reduces GHG emissions through the installation of instrument air compressors and related infrastructure to retrofit existing gas processing and compression facilities that previously relied on natural gas-driven pneumatic instrumentation systems for process control. The use of compressed air to operate these pneumatic systems eliminates the venting of natural gas (primarily methane) that occurred in the baseline scenario from the use of pressurized natural gas to operate the pneumatic instrumentation systems.
