GE Oil & Gas on said that LNG Canada has selected its technology for the proposed gas liquefaction plant in Kitimat, British Columbia.
LNG Canada selected the high-efficiency LMS100-PB dry low emission aeroderivative gas turbine as well as vertically and horizontally split centrifugal compressor technologies, GE said in a statement.
According to GE, the LMS100-PB is the largest aeroderivative gas turbine available with a free power turbine, ideally positioning it for large LNG applications. The LMS100 offers the highest simple-cycle efficiency of any industrial gas turbine. Rated at 105 megawatts and 45 percent efficiency at ISO conditions, the LMS100-PB provides clear advantages in total cost of ownership.
The aerodynamically coupled free power turbine provides speed, flexibility and high torque for typical LNG compressor loads especially during start sequencing with pressurized conditions in the refrigeration loop, avoiding the need for starter/helper motors.
LNG Canada has selected natural gas turbines for the liquefaction process to minimize fuel use and greenhouse gas emissions. It also recently signed a power agreement with BC Hydro to use clean, renewable electricity from BC Hydro for a portion of the electricity needed for the facility.
The company estimates the proposed facility will have a greenhouse gas emission intensity of about 0.15 tonne CO2e/tonne LNG produced, which is lower than benchmarks recently introduced by the B.C. government and among the lowest CO2-emitting LNG facilities in the world.
This is an important step forward for the proposed LNG Canada project, but the company must still ensure the project is economically viable and meet several other significant milestones related to gas supply, engineering and cost estimates, supply of labor and regulatory approval prior to making a final investment decision.
