Description
1. Real – world Case
In a large – scale petrochemical plant, the DS200NATOG3A was integrated into the process control system for a complex distillation unit. The distillation unit is responsible for separating various hydrocarbon components from crude oil. One day, there was a sudden change in the composition of the incoming crude oil due to a switch in the oil source.
The sensors connected to the DS200NATOG3A detected changes in parameters such as temperature, pressure, and flow rate at different stages of the distillation process. The DS200NATOG3A quickly analyzed this data and adjusted the control settings of the valves, pumps, and heaters in the distillation unit. By precisely regulating these parameters, it maintained the optimal separation efficiency of the unit. As a result, the plant was able to continue producing high – quality petroleum products without significant disruptions in the production process.
2. Applications
