Optimizing plant operations using digital twin

JFE Engineering is using a digital twin to make plant operation more efficient. Biogas plants use food waste as raw feedstocks to produce methane gas through fermentation by micro-organisms and generate electric power with gas engines. Because a wide variety of food waste is used, it is important to know the concentration of the substrate and the micro-organisms in the fermentation tank in detail to maintain stable operation. We developed a digital twin with “data assimilation” technology, which integrates the physical model of the anaerobic digestion reactor with real operational big data.
This makes it possible to know the details of the real fermentation tank and to operate the virtual fermentation tank accurately. AI-optimized operational conditions using a digital twin realizes stable and efficient operations.
