Siemens Gas and Power was recently selected to provide three 33-megawatt (MW) SGT-700 industrial gas turbines including a Long-Term Program (LTP) with Ascend Performance Materials’ nylon intermediate and specialty chemicals facility in Decatur, Alabama. This project will allow Ascend Performance Materials to retire assets that currently provide process steam for the facility. The shift to gas turbines for steam generation is part of Ascend’s long-term sustainability strategy to improve its environmental footprint and accelerate the growth of expanding its core businesses.
The LTP is scheduled for eight years. Under the terms, Siemens Gas and Power will perform all scheduled outages for the duration of the program.
The gas turbines will be manufactured in Siemens Gas and Power’s Finspång, Sweden plant in time for project commissioning, which is expected in Q4 2021.
The SGT-700 gas turbine, with a 6,500-rpm, two-stage uncooled free-power turbine that may operate at 50 to 105 percent of its nominal shaft speed, is designed for higher output and efficiency under a range of operating conditions. And with its high exhaust heat and ability to handle sudden load changes, the SGT-700 is ideal for simple cycle, combined cycle, cogeneration, and other heating applications.
