【 摘 要 】

The theoretical calculation results of the condensation recovery rate and the required cooling power of an engineering application unit shown that condensation recovery of N2O4 in the waste gas is feasible and valuable in engineering applications.A simulation model was performed by using HYSYS and according to condensate-recovery process flow. Thus two important engineering parameters were simulated which included the thermal load of condensation system and the flow of glycol-water solution. The test results of an engineering application device based on these parameters at Jiuquan Satellite Launch Center indicated that the recovery efficiency can be above 90.0%, the purity of N2O4 recovered can be up to 99.6%.
