With a total investment of around US$110 million from Siemens Energy and Braskem, the project provided a technological update of the system that serves the cracker, the main industrial unit of the petrochemical facility. Here, raw materials for the chemical and plastic sectors are produced. The optimized design is leading to an increased efficiency of the ethylene plant.
The two gas turbines and the combined cycle solution from Siemens Energy generate 38 megawatts of electrical power and provide 160 tons of steam per hour. Braskem estimates that the upgrade project reduce the cracking unit’s water consumption by 11.4 percent and CO2e emissions by 6.3 percent, mitigating environmental impacts and improving their sustainability target achievement. NOx emissions from the turbines are low at just 25 parts per million.
For Siemens Energy, the project also offered a chance to achieve a goal set in early 2019. The company committed to gradually increasing the hydrogen capability in gas turbines to 100 percent by 2030. The two gas turbines involved in the project completed in 2022, are co-fired with 40 to 60 percent hydrogen by volume.
