Siemens was recently selected to provide one feed and sales gas train and one refrigeration compression train for Encana’s Pipestone Processing Facility in Grand Prairie, Alberta, Canada. Designed to accommodate future capacity expansion, the Pipestone Processing Facility will provide Encana with 19,000 barrels per day of net raw condensate processing capacity plus 170 million cubic feet per day of net inlet natural gas processing capacity. Keyera will own the Pipestone Processing Facility and provide processing services to Encana. The Facility will have total processing capacity of 200 million cubic feet per day and is expected to start up in 2021.
The first train will consist of a Siemens SGT-750 gas turbine driving two Dresser-Rand DATUM compressors for feed and sales gas compression, combined with a Siemens waste heat recovery unit for process heat. The second train will consist of a Siemens electric motor-driven DATUM compressor for refrigeration compression with Siemens variable frequency drive.
In 2015, Siemens supplied three pipeline compressor trains driven by SGT-750 gas turbines to Central America-based Fermaca for its El Encino – La Laguna pipeline project. In 2017, China’s largest acrylic producer, Zhejiang Satellite Energy Co., selected Siemens to provide an SGT-750 gas turbine to drive two Siemens STC-SH single-shaft compressors for Phase II of its propylene dehydration plant. In 2015, Encana purchased 10 DATUM compression trains for its Cutbank Ridge Program, designed for the long-term development of natural gas resources in Northeast British Columbia.
