The serious corrosion problem at low temperature could be found in atmospheric-vacuum distillation unit, especially in the atmosphere overhead condenser.

常减压装置存在较为严重的低温位腐蚀问题，尤其是常压塔顶冷凝器腐蚀问题更为严重。

The air-cooled steam condenser (ACC) condenses the turbine exhaust steam or the de-superheated steam from the turbine bypass by rejecting the heat to the atmosphere.

空冷凝汽器（ACC）通过向大气释放热量对汽机排汽或汽机旁路的减温过热蒸汽进行冷凝。

By using the biochemical unit(condenser and washing tower), the pollute emitted to the atmosphere is less. The cleaning process is automatic.

由于采用了生化单元（ 冷凝器和洗涤塔），因此排到大气中的污染物为最小，清洗过程是全自动进行的。
