摘　　要：尿素装置联产三聚氰胺后 ,解吸系统需处理的工艺冷凝液量大幅增加。为确保废水达标回收 ,将解吸塔结构由浮阀塔盘改为ZUPAK高效规整填料 。When the urea unit coproduces melamine, the desorption system has to treat much more process condensate, and to ensure that the wastewater reaches the standard for recovery, the float valve trays in the desorbers are replaced with ZUPAK high efficiency structured packings, thereby enabling the wastewater to reach the standard for recovery.
