Abstract:

On the basis of the production indexes of the ammonia stripping system in phase III project in Baosteel, the process simulation and study are carried out. The simulated result tallies with the production indexes and are reliable. The soda adding amount, soda adding location and steam consumption are optimized. It is put forward that when production is expanded in phase III project, the amount of soda addition is 350kg/h, the location for feeding soda is the nineteenth column tray and steam flow rate is 10 300kg/h.
