简要介绍对两套水溶液全循环法尿素装置,采取淘汰部分陈旧设备,新增高效节能设备;部分塔设备进行内件更换;增加新的工艺流程等综合节能技术改造措施后,取得了尿素产能增加,吨尿素节约蒸汽250kg,节约氨5kg的效果。在尿素系统正常加氧的前提下,设备及管线腐蚀速率<30μm/a,生产强度在4.5~15.0t/d·m~3时,尿素生产装置各项工艺指标可灵活调节,实现了节能降耗的目的,并为企业带来可观的经济效益。
A brief introduction to the two sets of urea solution with full circulation of aqueous solution has been adopted to eliminate obsolete equipment and increase the efficiency of energy-saving equipment; some tower equipment to replace the internal parts; to add new technological processes and other comprehensive energy-saving technological transformation measures, achieved urea production increase , Tons of urea to save steam 250kg, saving 5kg ammonia effect. In the urea system under the premise of normal oxygen, equipment and pipeline corrosion rate <30μm / a, the production intensity of 4.5 ~ 15.0t / d · m ~ 3, the urea production plant process can be flexibly adjusted to achieve energy saving Consumption purposes, and bring considerable economic benefits to the enterprise.
