Russia’s OJSC Togliattiazot (ToAZ) is one of the world’s largest producers of ammonia. As Russian industries seek modernize their existing production facilities to increase environmental and economic sustainability, ToAZ wanted to modernize two GE Fitchburg industrial steam turbines at the company’s ammonia production facility in the city of Togliatti. Based on the results of a field test and an engineering study, GE proposed a new configuration of the low- and high-pressure steam turbines.
“The upgrade of the ToAZ compression trains is a crucial step that helps boost production capacity,” said Victor Kazachkov, chief operations officer of CJSC Togliattiazot, the plant’s managing company. “As the original equipment supplier, GE is familiar with our operations and has the technology expertise to provide a highly effective and reliable solution that may be implemented without affecting our existing workflow.”
The ToAZ upgrade will replace major components needed to amplify production capacity. The multiphase project includes plans to modernize the plant’s low pressure and high pressure of the GE industrial steam turbines that drive their corresponding low- and high-pressure syngas compressors in mechanical-drive mode. GE also will supply spare turbine parts for three additional compressor trains, which will help ToAZ reduce its operational costs by doubling the length of time between maintenance intervals.
THE WAY FORWARD
“ToAZ’s ammonia plant offers us an excellent opportunity to showcase both the durability of GE’s industrial steam turbines as well as our capabilities to provide parts to optimize the performance,” said Pascal Schweitzer, general manager of GE’s Power Services business in Europe and Russia. “With this project, ToAZ will be able to boost production capacity while cutting down the operating costs.”
