Pak Arab Fertilizer Private Limited自1978年以来一直在经营基于奥达工艺的硝酸磷肥厂。该技术由荷兰Stamenbon公司提供，工程由德国Udhe公司提供。硝酸磷肥路线为生产农艺平衡的复合肥提供了一条有趣的途径。安装后对原设计进行了多项改进，以满足性能保证。磷矿是生产NP的主要原料。工厂设计在约旦岩石和后来的摩洛哥，埃及和阿尔及利亚岩石磷酸盐和他们的混合物进行了测试。另一个瓶颈是CN分离离心机。该设备的故障使工厂以低速率运行，因此将其更换为过滤器桶（一种缓慢移动的装置）。这有助于提高生产质量和服务周期。为了改善环境，在溶解反应器中加入尿素溶液。在系统中增加了两个新的反应器来控制反应速率和消泡剂的消耗，这也有助于提高装置的生产能力。本文主要介绍硝酸磷肥装置的运行经验，以及为提高装置的可靠性所作的改进。
Pak Arab fertilizers private Limited has been operating its nitrophosphate plant based on the ODDA process since 1978. The technology has been supplied by Stamicarbon Holland and engineering by Udhe Germany. Nitrophosphate route provides an interesting avenue for producing an agronomically balanced complex fertilizer. Numbers of improvements are made in original design since after installation to meet the performance guarantees. Rock Phosphate is the main raw material for NP production. Plant was designed on Jordan rock and later Morocco, Egyptian and Algerian rock phosphates and their blends are tested. The other bottle neck was CN separation centrifuges. Failure of this equipment kept the plant operation on low rate hence these were replaced with Filter drums a slow moving unit. This helped to improved production quality and service period. To improve environment, NOx abatement Urea solution is added to Dissolving reactor. Two new reactors added to system to control reaction rate and anti foaming consumption was reduced drastically and it also helps in increasing production capacity of plant. The main thrust of this paper is to present the operating experience of nitrophosphate plant, improvements made at this complex to improve reliability of complex.
