苯酐装置采用部分冷凝器的探讨

Discussion on Adding Partial Condensator in Phthalic Anhydride Plant

介绍了苯酐装置系统中增加部分冷凝器的流程,操作讨论了加部分凝冷器前后的经济效益。结果表明,装置系统改造能提高切换冷凝器的寿命,提高苯酐收率。

The flow sheet and operation in phthalic anhydride plant system after the adding partial condensator were introduced. The economical profit before and aftere the adding partical condensator was discassed. It was showed that the plant system modification could prolong condensator life and enhance the yield of phthalic anhydride.
