Real-time Simulation and Intelligent Decision-making Practice

The real-time online optimization (RTO) system was successfully deployed, tested, and implemented on an offshore oil and gas field platform. The system has been running stably, and the trends of changes in key process parameters are highly consistent with the expectations of the calculation model. In the natural gas tri-ethylene glycol dehydration regeneration process, process parameters need to be adjusted in real time according to changes in the actual working conditions. Therefore, implementing online simulation and optimization for this type of device is particularly crucial. By combining steady-state models with on-site data, the system can conduct real-time simulation and optimization operations, providing intelligent guidance for actual production, thereby significantly enhancing the economic benefits of the plant and providing strong support for production decisions. Optimizing the TEG circulation volume and stripping volume of natural gas dehydration process is approximately 2.03 million yuan/year in benefits.
