| 德州奥斯汀2008年4月16日消息，艾默生过程管理公司宣布其为在阿根廷首都布宜诺斯艾利斯北部80公里处的聚苯乙烯生产商Petrobras Zarate执行一个多年数字自动化项目，用于增加产量并减少停工期，使工厂实现现代化。 通过现代化建设，产量上涨了3%-5%，涨至每年66,000吨。工厂现在实用率可达99％，产品可靠率增长了2-3％。 该工厂生产高压缩型，通用晶体和bioriented sheet 聚苯乙烯，是位于布宜诺斯艾利斯 Petrobras Energia公司的一部分。聚苯乙烯是一种轻质塑料材料，用于制造一次性食品包装袋，刀具、鞋类、学校材料和其它用于冰箱、空调和真空吸尘器。 作为Petrobras Zarate过程自动化的提供商，艾默生提供全方位的咨询、员工培训和PlantWeb®数字架构、AMS® Suite资产管理软件，DeltaV™自动化系统的安装服务。该项目使工厂多种操作实现现代化，包括水、蒸汽、空气和反应器操作。 在Petrobras Zarate的聚苯乙烯生产已经受到了一个20世纪80年代的DCS的限制。Petrobras的仪器管理者说：“我们需要使我们的技术更加现代化并保证其可以回报市场的需求。” Petrobras Zarate维修经理Adolfo Suiffet说：“在与艾默生结成合作伙伴针对技术更新问题时，在我们的脑海中已经存有了多个想法。我们讨论了一个关于控制系统的迁移战略，此战略能提供给我们更大的可靠性，在我们的预算范围之内，遵从中长期战略并满足管理和业务方面的需求。” 向数字化的转变在2002 至2005年间就已经开始执行了。借助于艾默生的协助和其数字化系统及仪表技术，Petrobras Zarate在2005年节省了1.13美元。全体人员实现了完整的DeltaV系统转化，而没有停产。每年工厂运行所需的停产减少了一半，由于工厂人员现可以在更可靠数据基础之上自行做出决定，停产变成了每两年一次。 Suiffet.说：“由于改造及时，应用了正确的诊断系统，维护成本大大减少。” 艾默生拉丁美洲总裁Leo Rodriguez说：“Petrobras小组的成就对于该厂是非常具有价值的，也是工程专家和技术的一个可能性案例。通过他们的创新，计划组由艾默生帮助已将PlantWeb数字技术用到了卓越的操作和成功生产之上。” Petrobras Zarate应用的是基金会现场总线通信技术，与艾默生的DeltaV数字系统，Rosemount®流量仪、水平和温度仪表，Micro Motion®科里奥利流量计和Fisher®阀门一起构成一个网络。 高级控制工具可以提高产品质量和性能。例如，在DeltaV系统中神经网络软件的应用，可使在反应器中的质量预测更有效，并且Petrobras Zarate可在工厂中精确到某一个产品。来自AMS Suite的预测诊断，包括将信息传递至运营的智能设备管理器和现场设备快速决定的维护人员。 PlantWeb架构是一个开放式的，基于标准的数字自动化解决方案，与智能现场设备、数字系统、控制过程软件、管理设备和其它资产系统构成网络，为工厂管理提供信息，包括预测未发生的事情和避免生产中断和停产的校正行为。 Emerson completes digital automation, improves operation of polystyrene plant in Argentina Austin, Texas （April 16, 2008） – Emerson Process Management today announced production gains and reduced plant downtime through a multi-year digital automation project at Petrobras Zarate, a polystyrene manufacturing facility 80 kilometers north of Buenos Aires, Argentina. Through the modernization, production rose by 3 to 5 percent — to 66,000 tons per year. The plant‘s availability is now 99 percent and product reliability is up by 2 to 3 percent. The plant, which produces high impact, general purpose crystal and bioriented sheet polystyrene, is part of Petrobras Energia, an integrated energy company in Buenos Aires. Polystyrene is a lightweight plastic used to make items such as disposable food containers and cutlery, footwear, school materials, and parts used in refrigerators, air conditioners and vacuum cleaners. As Petrobras Zarate‘s process automation supplier, Emerson provided consulting, staff training, and installation of its PlantWeb® digital architecture, AMS® Suite asset management software, and DeltaV™ automation system. The project modernized the plant‘s high impact and crystal polystyrene facilities, including the water, steam and air utilities and the reactor operations. Polystyrene production at Petrobras Zarate had been limited by a 1980s-era distributed control system. "We needed modernization to place the plant in the vanguard of technology and ensure it could respond to the needs of the market," said Roberto Gorbaran, instrumentation supervisor at Petrobras. Plant managers had several goals in mind when they decided to partner with Emerson for the technology upgrade. "We discussed a migration strategy towards a control system that could give us greater reliability, would fall within our budget, would comply with medium- and long-term strategy and satisfy management and the business," said Adolfo Suiffet, maintenance manager at Petrobras Zarate. The transformation to digital was implemented in stages between 2002 and 2005. Petrobras Zarate saved $1.13 million in 2005 when, with Emerson‘s assistance and aided by its digital valve and instrument technology, plant personnel completed the final hot cutover of operations control to the DeltaV system without stopping production. Annual plant stoppages have been reduced by half, to once every two years, because plant staff can now make decisions based on more reliable data about their operations. "Thanks to being able to intervene at the right moment, with the right diagnosis, maintenance costs have been cut. " said Suiffet. "The accomplishments of the Petrobras team are highly valuable to the plant and a great example of the results possible through engineering expertise and technology," said Leo Rodriguez, president of Emerson Latin America. "Through their innovation, the plant team assisted by Emerson has used PlantWeb digital technology for operational excellence and manufacturing success." The Petrobras Zarate plant uses FOUNDATION fieldbus communications to network Emerson‘s DeltaV digital systems, Rosemount® flow, level and temperature instruments, Micro Motion® Coriolis flowmeters and Fisher® valves with Fisher FIELDVUE® digital valve controllers. Advanced control tools increase production quality and capacity. For example, application of neural network software in the DeltaV system made quality prediction in the reactors more effective, and Petrobras Zarate was able to up rates for certain products in the plant. Predictive diagnostics from AMS Suite: Intelligent Device Manager deliver information to operations and maintenance personnel for fast decisions on field devices. PlantWeb architecture is an open, standards-based digital automation solution that networks intelligent field devices, digital systems, and software to control processes and manage equipment and other assets. It delivers information for facilities management, including predictive alerts of pending malfunctions and guidance for corrective action to avoid production interruptions and shut downs. 声明：本文为
