关于客户
Vale Fertilizantes (Vale) 于 2018 年被 Mosaic 收购，是巴西领先的化肥制造商之一。该公司拥有四个重点领域不同的设施，包括磷酸盐和氮肥。
挑战
减少生产损失
2013 年，公司确定需要对其酸硝酸装置进行维护和运营，以减少生产损失并提高年产量。 Vale 注意到 2011 年至 2012 年硝酸生产存在缺口，并发现三台设备造成了主要损失，包括两台弱酸冷凝器和一台压缩机排气冷却器。冷凝器的损失是由于厚度损失、备用冷凝器缺乏可用性和壳裂。
由于 15 个月的产量损失超过 14,000 吨，淡水河谷的目标是到 2015 年 8 月将年度损失减少 10,000 吨。
解决方案
需要改进维护策略和可靠性
为了改进其维护策略和提高可靠性，Vale 实施了 Predix 资产绩效管理 (Predix APM)（以前称为 Meridium Enterprise APM），具体包括 APM 可靠性和 APM 完整性解决方案。这些解决方案包括生产分析、厚度监测和根本原因分析 (RCA) 功能。
Vale 与 Predix APM 团队合作进行 RCA 审计，以分析冷凝器系统并记录故障，并制定策略以防止再次发生。在对冷凝器系统进行分析之前，它的功能是未知的，并且弱酸流量低于定义的限制。这个问题意味着一个更大的挑战，即公司需要的不仅仅是维护修复，还需要文化变革来完全接受和实践持续的可靠性工作。

Advanced Elastomer Systems Upgrades Production
In order to maintain its share of the international market for thermoplastic elastomers AES recently expanded its Florida plant by adding a new production line. While the existing lines were operating satisfactorily using a PROVOX distributed control system with traditional analog I/O, AES wanted advanced technology on the new line for greater economy, efficiency, and reliability. AES officials were anxious to get this line into production to meet incoming orders, but two hurricanes slowed construction.

Field Device Asset Management For Chemical Company in China
Chinese chemical subsidiary of multinational corporation serves customers throughout the world. Sales offices and research and technology centers are strategically located to provide rapid response to customer requests. Just two workers were assigned to maintain thousands of intelligent instruments in three production units, so they could do little more than react to device issues as they appeared. This costly maintenance method inevitably led to unexpected downtime when a critical instrument failed. Plant management recognized the need to change from reactive to predictive maintenance for all assets, including instruments and control valves, but help was needed in implementing such a technology-based initiative.
