一、系統描述
  醋酸是一種十分重要的工業原料,其市場非常廣闊.它的生產過程主要分為兩個大的過程: 合成和精餾.前者是發生化學反映生成醋酸的過程, 后者則是將生成的醋酸通過學,物理過程來進行提純.其工藝流程圖如下:
 2、本工藝的特點和難點
  醋酸的生產是個塔體非常多的系統,調節回路眾多,系統的關聯性非常強,一個參數的控制的好壞直接影響到其參數的控制的成敗.一個系統的波動可能帶垮整個系統.,因為其產品醋酸的濃度要求非常高,達到99.9%以上,因此對反應溫度,以及流量等參數的控制要求非常平穩,合成反應器的中溫要求170正負0.5度,醋酸蒸發器液位要求達到正負1%,還有的流量非常不穩定,可控性不太好.這些都對控制的精度提出了很高的要求.
  3、工藝對控制系統的要求
  a、實現各個單元操作的集中控,包括:溫度、壓力、流量、液位等物理量的測與控制。動態參數檢測、控制必須準確、可靠。合成反應器的中溫要求170正負0.5度,醋酸蒸發器液位要求達到正負1%,
  b、必要的遙控措施,對突發事件如停電等,系統應采取相應的保護措施,確保在緊急情況下或需要的時候對一些關鍵的控制點(閥門、馬達等)實施遙控。
  c、配置必要的報和聯鎖。
  d、重要參數的記錄和方便地查閱其實時趨勢和歷史趨勢。
  e、可隨時測有關單元的有關參數或重要設備的運行情況。
  f、控制系統操作簡單,參數設置、調整方便,便于操作,人性化的操作界面。
  g、操作員站顯示整個生產工藝流程,修改和打印各種有關參數。
 2、FB-2000NS系統硬件配置
  本控制系統采用了三個控站,和兩個現場控制站.穩定性.兩個現場控制站也采取了熱備用冗余,任何一個出現了故障,自動切換到另外一個上正常運行.也增加了系統的可靠性和穩定性.所有的模擬量輸出都采取了熱備用,還有重要的顯示參數也都采取了熱備用..所有的模擬量都采取了和現場信號的光電隔離,所有的現場信號均通過了安全柵隔離. DCS的硬件配置如下: FB-2001NS -4塊,FB-2005NS-3塊,FB-2010NS 16塊 ,FB-2020NS 28塊, FB-2030NS 1塊 ,FB-2040NS-4塊 FB-SC20NS/R14塊,FB-SC14NS/R-4塊,FB-SCNS14-8塊.FB-SC30NS1塊. FB-S2NS-4塊.另外,報表打印機一臺。
