| Abstract: | Taking 75 kt/a thermal-process phosphoric acid plant as an example, by heat energy analysis and calculation, the heat energy recovery scheme is brought forward that the middle pressure saturated steam is superheated to be used for power generation, the reaction and dilution heat are recovered to produce low pressure saturated steam. Process simulation is carried out by CHEMCAD software, and the scheme is considered theoretically feasible. |
| Keywords: | thermal-process phosphoric acid plant recovery of low level heat energy process simulation |
