摘要
化肥厂原料液氨带油进入尿素系统,尿素设备的换热段高温部位产生一定量的缩二脲垢,导致换热效率和产品产量下降。通过化学清洗彻底清除气提塔内的油垢、污垢等,使其安全、高效生产运行。
The liquid ammonia with oil can produced biuret scale on the urea system in chemical fertilizer plant. The efficiency of heat exchanger and producing capacity of urea were reduced. By chemical cleaning process, the biuret scale and fouling of stripping tower were removed; and the operation is safe and high efficieney.
