產品概述
製程操作中流程管理的工業問題
很多類型的製程工廠都是以實現安全和效率的關鍵製程活動為主。這些製程活動來源許多領域,包括手動SOP、現有的控制系統以及操作員多年來獲得的隱性知識。由於操作人員的退休率高,新一代的工程師和操作員未掌握這些知識。操作程序的準確性不足會導致操作錯誤。通製強調工廠以優化效率運行以及時刻關注安全問題,關鍵在於企業獲得操作知識和良好實踐,並持續、準確地執行。
行業翹楚已經認識到自動化程序需要標準,並成立了ISA-106委員會。該委員會用於創建標準、推薦的操作規範以及流程設計和執行方面的技術報告,以實現持續製程操作的自動化。橫河電機努力參與該標準化進程,並提出了解決方案,可以解決新興標準—模組化的流程自動化中的問題。
文檔化並驅動良好實踐
模組化的程序自動化將谘詢的專業知識與流程管理能力相結合,以便:
- 在製程工廠中獲取、優化和維持流程知識和控制。
- 在工廠控制系統中以適當的級别執行流程,以滿足流程的可靠性和靈活性要求。
- 將流程集成到操作員界面和報警系統中,提高態勢感知能力。
模組化流程自動化的功能
- Vigilant程序谘詢和工具 - 根據操作要求,將程序執行模組的工具、功能和谘詢翹楚人士功能內定到控制系統結構中。
- 知識工程 - 無論是在手動的現有控制系統還是在操作員的心中,MPA顧問和工程師都是獲取和記錄當前使用程序的翹楚。
- 模組化的工程 – 在新興ISA-106標準作業和研發方法方面,基於標準的設計可以確保用戶的程序性投入始終可靠且適合操作人員。
- 先進的決策支持整合 - 將程序集成到高性能的HMI和報警系統中,可以在製程條件和狀態下為操作員提供高層次的態勢感知能力。
- 操作員模擬 - 通製整合和部署操作員培訓系統來提高MPA的價值,以培訓工廠操作員對異常條件和製程轉換的有效執行做出適當的反應。

Exapilot軟件
Exapilot是一款在線導航工具,可以指導操作員逐步進行工廠運行操作步驟。
雖然生產控制系統使工業工廠的大部分運行實現了自動化,但是操作員仍然需要手動對非常規製程進行干預,如工廠開車/停車和產品裝載/分級/配方變化等。雖然開車和停車操作不常發生,甚至幾年才進行一次,但是幾乎每天都會進行產品切換。
經驗豐富的操作員清楚地掌握了這些製程的每個步驟,但是如果他們不在現場的話該怎麼辦?發生意外情況時,缺乏經驗的操作員能否處理?
Exapilot可以解決這些問題。Exapilot可以指導操作員每一步操作,防止操作員出錯,甚至能夠在檢測到製程危險情況時及時報警。標準化的操作提高了產品質量,縮短了生產周期,並且減少了製渡產品。這樣不只降低了公用設施的成本,而且工廠還能夠以更少的投入運行。Exapilot將操作員的專門知識轉化為標準化的步驟流程圖,操作員可以在整個製程中充分利用該流程圖進行導航。
通製減少操作員失誤和生產損失,提高了效率,降低了整體運行成本。
自從Exapilot發布後,已經出售了1000多個軟件許可。其中,大多數用戶來自化工、石化和石油天然氣行業。
(1) 用組合圖標表示操作流程(組態期間)
Exapilot使用圖標表示標準的工廠運行組件。只需定位並按照順序連接圖標即可創建標準的操作流程。創建簡單的分級結構即可表示複雜的流程。無需專業工程技能即可配定Exapilot。
(2) 避免遺漏步驟(操作期間)
對於製程的每一步,畫面上都會顯示對話框,指導操作員進行下一步操作。可以配定互鎖順序,防止操作員遺漏步驟。
(3) 將DCS操作和監視自動化
可以將閥門打開、斜坡測試、液位檢查以及泵的啟停等製程自動化。
(4) 與生產控制系統無縫連接
Exapilot通製製程連接(OPC)接口的標準OLE與生產控制系統(PCS)無縫連接,而無需PCS工程。Exapilot已經針對橫河電機的CENTUM系列PCS進行優化,但同時也支持其他公司的DCS和PLC系統。
(5) 將標準操作程序文檔化(SOP)
可以通製自文檔化功能打印Exapilot創建的工作流,用作標準操作程序(SOP)。
(6) 將Exapilot用作運行仿真器
通製在試用模式中使用調試功能,可以將Exapilot用作運行仿真器。無需中斷實際的工廠運行即可將工廠數據實時導入Exapilot進行模擬。
(7) 充分發揮經驗豐富操作員的作用
使用Exapilot將非標準操作自動化,經驗豐富的操作員便可以花費更多的時間來增強和優化用戶整個工廠的操作流程。這樣可以提高效率,降低運行成本。

This paper shows how to improve distillation operations by focusing on procedure automation. It will review the importance of using procedures in distillation operations and highlights the collaboration work underway between Fractionation Research Inc. (FRI) and Yokogawa Corporation to improve procedural operations.
Operational error is the single biggest reason for unscheduled shutdowns in process plants, causing several millions of dollars in damages and losses per year. Combine this with an aging skilled workforce leaving the work place, with inexperienced people to replace them, and there is no doubt that process plants face a challenging problem.
Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's focus on system reliability, security, dependability, and robustness. Dubbed "Vigilance", the campaign created a unified message for the company and greatly helped expand awareness of the Yokogawa brand and corporate philosophy.
The world of process automation is governed by procedures. While we like to refer to the process industries as being largely "continuous", this could not be further from the truth. Process manufacturing is constantly in flux.
Large process industry companies have recently started building plants with world-class safety and profitability to reinforce their competitive edge in the global market. As for plant operations, support functions for improving operators' plant operation skills and for extending operators' maximum capability are required to the DCS so that an operator can expand the area of plant monitoring or operate a plant with higher cost- consciousness.
In 1999, Yokogawa Electric Corporation formed an alliance with Shell Global Solutions International B.V. (SGSI) in Advanced Process Control (APC), and both companies have since jointly developed products. This alliance successfully combined SGSI's experience gained through more than 800 projects in more than 30 years and Yokogawa's great deal of experience with the process control market, and strengthened the scheme to provide the APC technology.
In recent years, safety and profitability have become ever more important in the process industry due to fierce global competition. Greater emphasis is being placed on highly efficient plant operation for reducing the increasing energy bill.
Recently, standardization of procedural automation of manual operations has been promoted mainly by the International Society of Automation (ISA), and the functional requirements necessary for automation are being studied by the ISA106 committee in the US.
For a coal fired power generation plant (hereafter referred to as "BTG facilities," in which "BTG" stands for boiler, steam turbine, and generator) supplying power to a large-scale production plant, the CO2 emissions from such facilities are a critical issue today.
Remarkable progress in information technology has led to open architecture systems and networking in the manufacturing industry. In such industry, remote monitoring systems based on public communication lines or the Internet, and or collaboration of control, information, and corporate systems based on standardized interfaces such as OLE for Process Control (OPC) are now widely used via networks.
Due to emerging competitors from the rapidly growing countries such as India and China and the global economic downturn triggered by the Lehman shock, many companies in the process industries are struggling to survive the severe global competition.

Process plants are run according to operational procedures. These procedures consist of a set of tasks that are executed in a consistent manner to achieve a specific objective, such as starting up, shutting down or transitioning a unit as part of making a product.
Process plants require operational procedures in order to produce products. These procedures consist of a set of tasks that are executed in a consistent manner to achieve a specific objective such as starting up or shutting down, or transitioning to a different product. The level of detail, purpose and frequency of use of these procedures varies by process, company and site—but in all cases these procedures should be the basis for plant operations.
Manual operations live on and even thrive in largely automated process plants, and they are often the cause of safety incidents.
