德州奧斯汀2008年4月16日消息，艾默生過程管理公司宣布其為在阿根廷首都布宜諾斯艾利斯北部80公里處的聚苯乙烯生產商Petrobras Zarate執行一個多年數字自動化項目，用于增加產量并減少停工期，使工廠實現現代化。 通過現代化建設，產量上漲了3%-5%，漲至每年66,000噸。工廠現在實用率可達99％，產品可靠率增長了2-3％。 該工廠生產高壓縮型，通用晶體和bioriented sheet 聚苯乙烯，是位于布宜諾斯艾利斯 Petrobras Energia公司的一部分。聚苯乙烯是一種輕質塑料材料，用于制造一次性食品包裝袋，刀具、鞋類、學校材料和其它用于冰箱、空調和真空吸塵器。 作為Petrobras Zarate過程自動化的提供商，艾默生提供全方位的咨詢、員工培訓和PlantWeb®數字架構、AMS® Suite資產管理軟件，DeltaV™自動化系統的安裝服務。該項目使工廠多種操作實現現代化，包括水、蒸汽、空氣和反應器操作。 在Petrobras Zarate的聚苯乙烯生產已經受到了一個20世紀80年代的DCS的限制。Petrobras的儀器管理者說：“我們需要使我們的技術更加現代化并保證其可以回報市場的需求。” Petrobras Zarate維修經理Adolfo Suiffet說：“在與艾默生結成合作伙伴針對技術更新問題時，在我們的腦海中已經存有了多個想法。我們討論了一個關于控制系統的遷移戰略，此戰略能提供給我們更大的可靠性，在我們的預算范圍之內，遵從中長期戰略并滿足管理和業務方面的需求。” 向數字化的轉變在2002 至2005年間就已經開始執行了。借助于艾默生的協助和其數字化系統及儀表技術，Petrobras Zarate在2005年節省了1.13美元。全體人員實現了完整的DeltaV系統轉化，而沒有停產。每年工廠運行所需的停產減少了一半，由于工廠人員現可以在更可靠數據基礎之上自行做出決定，停產變成了每兩年一次。 Suiffet.說：“由于改造及時，應用了正確的診斷系統，維護成本大大減少。” 艾默生拉丁美洲總裁Leo Rodriguez說：“Petrobras小組的成就對于該廠是非常具有價值的，也是工程專家和技術的一個可能性案例。通過他們的創新，計劃組由艾默生幫助已將PlantWeb數字技術用到了卓越的操作和成功生產之上。” Petrobras Zarate應用的是基金會現場總線通信技術，與艾默生的DeltaV數字系統，Rosemount®流量儀、水平和溫度儀表，Micro Motion®科里奧利流量計和Fisher®閥門一起構成一個網絡。 高級控制工具可以提高產品質量和性能。例如，在DeltaV系統中神經網絡軟件的應用，可使在反應器中的質量預測更有效，并且Petrobras Zarate可在工廠中精確到某一個產品。來自AMS Suite的預測診斷，包括將信息傳遞至運營的智能設備管理器和現場設備快速決定的維護人員。 PlantWeb架構是一個開放式的，基于標準的數字自動化解決方案，與智能現場設備、數字系統、控制過程軟件、管理設備和其它資產系統構成網絡，為工廠管理提供信息，包括預測未發生的事情和避免生產中斷和停產的校正行為。 [FONT=times] original text [/FONT] [font=times][Color=#708090]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.[/color][/font]
