焦化废水蒸氨工艺的比较

Comparison of ammonia stripping processes with coking waste water

介绍了焦化废水的来源和危害。分析了直接蒸汽蒸氨工艺、导热油蒸氨工艺、管式炉蒸氨工艺的优缺点,比较了2种蒸氨工艺的运行费用。最后提出了选择蒸氨工艺的建议。

The source and harm of coking waste water are described. The advantages and disadvantages of the ammonia stripping process with direct steam, ammonia stripping process with heat conducting oil and ammonia stripping process with pipe still are analyzed and the operation costs of two ammonia stripping processes are compared. Finally the suggestions are made for the selection of ammonia stripping process.
