聚天冬氨酸锌在大颗粒尿素项目中的应用

Application for Aspartic Acid Zinc in the Project of Large Granular Urea

对中海石油华鹤煤化有限公司增值性尿素项目情况进行简介,重点介绍聚天冬氨酸锌在大颗粒尿素中的应用。聚天冬氨酸锌尿素具有肥效周期长、氮元素利用率高、氮肥利用率高、作物的增产幅度较大等特点。这种技术首次应用在大颗粒尿素生产中。鉴此,主要介绍聚天冬氨酸锌尿素产品的工艺原理,工艺流程、生产运行情况及设备性能。

In It gives a brief introduction to the project of accretive urea in CNOOC Huahe Coal and Chemical Co., Ltd.The key point in the project is the usage of aspartic acid zinc in the large granular urea.The aspartic acid zinc has such features as long ~ycle fertilizer efficiency, high-usage of nitrogen and high increase range in crops＇ growth.Thig is the first time that the technology has applied to the production of the large granular urea.Considering this, the paper fixes its eyes on the principle and process of the craft, and also the situation in the process of production and the performance of the facilities.
