The feed and sales gas train features two high-efficiency DATUM centrifugal compressors and gearbox, driven by a 40 MW SGT-750 industrial gas turbine. The refrigeration train consists of a gearbox and an electric motor-driven DATUM compressor with a variable frequency drive. The project is the first application of this generation of gas turbine for a gas processing plant in North America.
The dry-low emissions (DLE) combustion system of the SGT-750 turbine offers world-class emission performance and fuel flexibility over a wide load range. The turbine can achieve single-digit NOX emission levels down to a 20% load. The compression train also includes a waste heat recovery unit, which will enhance processing efficiency and further contribute to reducing the plant’s carbon footprint.
The facility has a total sour gas processing capacity of 200 million ft3/d (with acid injection capabilities), along with 24 000 bpd of raw condensate processing capacity and associated water disposal facilities.
A flexible long-term service contract is in place between Siemens Energy and Keyera Partnership. As part of the agreement, Siemens Energy will provide tailored maintenance services to Keyera Partnership for the SGT-750 installation.
“The fact that Siemens Energy was selected for both compression trains with a long-term service contract is a testament to confidence not only in the technical capabilities of our equipment but also in our ability to ensure smooth, on-time delivery and execution,” said Patrice Laporte, Head of North America Industrial Applications Products for Siemens Energy. “The high efficiency of the DATUM compressors, coupled with the low-emissions profile and industry-leading fuel efficiency of the SGT-750 gas turbine, will enable the Pipestone facility to ensure compliance with applicable Canadian regulations and achieve a lower carbon footprint relative to other processing facilities of comparable size.”
