Study and simulation of water treatment unit using Aspen Water

Today boilers play an important role in combined cycle power plant in power industry. These boilers feeding water must be pure and free of salt that under the temperature and pressure of boilers. The particles do not cause any problem by sediment and carrying water drops. Clearing boilers feeding water from impurity and insoluble gas in Mashhad combined cycle power plant is carried out by adding CaO and using resin beds. In this research, simulation of the water treatment unit decarbonating was carried out by Aspen Watersoftware. The results show the improvement of process efficiency and the optimization of chemicals use and other specific parameters. In this research, effect of FeCl3 flow rate variation on pH and species concentration CaO flow rate is investigated and using NaOH for removing hardness and desalination was studied as well.
