| Abstract: | The liquid ammonia is heated in the ammonia evaporator with low pressure steam as the heat source for gaseous ammonia in ammonium phosphate （MAP/DAP） production. According to the heat balance calculation, it is considered feasible that 100 ℃ steam condensate from phosphoric acid concentration plant is used as heat source to obtain gaseous ammonia, after the scheme implementation, the mass of saving steam is about 120 000 t and equivalent to cost-saving 4.97 million RMB Yuan per year. |
