摘要
尿素和三聚氰胺系统联运,三聚氰胺返回尿素工艺碳铵液造成尿素系统水碳比增高,尿素转化率下降,造成中,低压系统负荷增加,蒸汽冷凝液系统超温超压,尿素蒸汽冷凝液系统改造。
While melamine returns to ammonium carbamate solution, water-carbom ratio in urea system rises and urea conversion rate decreases. Load in low and medium pressure system rises. Therefore steam condensate system must be modifird.
