Projeto de um sistema supervisório para uma planta de produção de hidrogênio

Abstract

Due to climate change and the increase in global temperature, the decarbonization movement of greenhouse gas-emitting sectors has gained momentum. In this context, green hydrogen emerges as a potential solution, as it is produced from renewable sources and, when manufactured through alkaline water electrolysis, does not emit carbon dioxide. The substitution of fossil fuels used in industrial processes, cargo transportation, or gray hydrogen production is a global trend, with many nations increasing their investments in green hydrogen production technologies. The green hydrogen production plant is a process that requires careful attention due to the high pressures and temperatures present in the system. Monitoring and controlling sensors and actuators is essential to ensure production safety and efficiency. The automation of this process involves real-time monitoring and data acquisition of the system, which are key features of SCADA supervisory systems. This research presents the development of a supervisory system for a green hydrogen production plant, with the design of interactive screens that enable real-time communication with the main process controller. The implementation of a SCADA system in a real hydrogen production plant, with alarms, notifications, and real-time monitoring, proved to be a promising solution to enhance efficiency and safety in green hydrogen production.
