OAT是对高压法三聚氰胺生产过程中产生的一种副产品的统称，正常生产中三聚氰胺产品中OAT含量一般在200×10-6，若含量过高会引起三聚氰胺产品浊度超标。本文简单概述了意大利欧技公司高压法三聚氰胺生产工艺基本工艺流程，详细阐述了该工艺 OAT 产生和去除的过程，对正常生产中造成高压法三聚氰胺产品 OAT 含量升高的原因进行了分析，通过分析，总结了高压法三聚氰胺生产工艺中防止产品浊度超标操作注意事项。

Generally OAT refers to by-products produced during melamine production with high pressure technology. The normal OAT content in melamine is 200×10-6 and higher content may result in high turbidity of melamine product. In this paper, basic simplified process flow of the high pressure production technology of melamine from Eurotecnica SPa, Italy was introduced, and generation and removing processes of OAT were described. The reasons to cause high OAT content in melamine during melamine production with high pressure technology were analyzed, the operation precautions to prevent from high turbidity of melamine product were summarized..
