在水溶液全循环法尿素生产工艺的蒸发冷凝液中 ,二表液作为系统补水 ,一表液去碳铵液槽 ,经解吸后排放。解吸废液中含有尿素 ,不仅造成浪费 ,而且污染环境。采用深度水解是解决该问题的最佳方法 ,但装置投资大 ,运行要求及费用高。我公司尿素装置原设计能力为 4万ｔ/ａ。随着生
In the whole process of circulating aqueous urea solution condensate evaporation process, the two table liquid as a system of water, a liquid to the ammonium bicarbonate tank, after desorption emissions. Desorption of waste containing urea, not only waste, but also pollute the environment. Depth hydrolysis is the best way to solve the problem, but the device investment, operating requirements and high costs. The original design capacity of urea plant of our company is 40,000 t / a.
