一、系統(tǒng)描述
　　醋酸乙烯是一種十分重要的工業(yè)原料,其市場(chǎng)非常廣闊.它的生產(chǎn)過(guò)程主要分為兩個(gè)大的過(guò)程: 合成和精餾.前者是發(fā)生化學(xué)反映生成醋酸乙烯的過(guò)程, 后者則是將生成的醋酸乙烯通過(guò)學(xué),物理過(guò)程來(lái)進(jìn)行提純.其工藝流程圖如下:
　2、本工藝的特點(diǎn)和難點(diǎn)
　　醋酸乙烯的生產(chǎn)是個(gè)塔體非常多的系統(tǒng),調(diào)節(jié)回路眾多,系統(tǒng)的關(guān)聯(lián)性非常強(qiáng),一個(gè)參數(shù)的控制的好壞直接影響到其他參數(shù)的控制的成敗.一個(gè)系統(tǒng)的波動(dòng)可能帶垮整個(gè)系統(tǒng).,因?yàn)槠洚a(chǎn)品醋酸乙烯的濃度要求非常高,達(dá)到99.9%以上,因此對(duì)反應(yīng)溫度,以及流量等參數(shù)的控制要求非常平穩(wěn),合成反應(yīng)器的中溫要求170正負(fù)0.5度,醋酸蒸發(fā)器液位要求達(dá)到正負(fù)1%,還有乙炔的流量非常不穩(wěn)定,可控性不太好.這些都對(duì)控制的精度提出了很高的要求.
　　3、工藝對(duì)控制系統(tǒng)的要求
　　a、實(shí)現(xiàn)各個(gè)單元操作的集中監(jiān)控，包括：溫度、壓力、流量、液位等物理量的監(jiān)測(cè)與控制。動(dòng)態(tài)參數(shù)檢測(cè)、控制必須準(zhǔn)確、可靠。合成反應(yīng)器的中溫要求170正負(fù)0.5度,醋酸蒸發(fā)器液位要求達(dá)到正負(fù)1%,
　　b、必要的遙控措施,對(duì)突發(fā)事件如停電等，系統(tǒng)應(yīng)采取相應(yīng)的保護(hù)措施，確保在緊急情況下或需要的時(shí)候?qū)σ恍╆P(guān)鍵的控制點(diǎn)(閥門、馬達(dá)等)實(shí)施遙控。
　　c、配置必要的報(bào)警和聯(lián)鎖。
　　d、重要參數(shù)的記錄和方便地查閱其實(shí)時(shí)趨勢(shì)和歷史趨勢(shì)。
　　e、可隨時(shí)監(jiān)測(cè)有關(guān)單元的有關(guān)參數(shù)或重要設(shè)備的運(yùn)行情況。
　　f、控制系統(tǒng)操作簡(jiǎn)單，參數(shù)設(shè)置、調(diào)整方便，便于操作，人性化的操作界面。
　　g、操作員站顯示整個(gè)生產(chǎn)工藝流程，修改和打印各種有關(guān)參數(shù)。
　2、FB-2000NS系統(tǒng)硬件配置
　　本控制系統(tǒng)采用了三個(gè)監(jiān)控站,和兩個(gè)現(xiàn)場(chǎng)控制站.穩(wěn)定性.兩個(gè)現(xiàn)場(chǎng)控制站也采取了熱備用冗余,任何一個(gè)出現(xiàn)了故障,自動(dòng)切換到另外一個(gè)上正常運(yùn)行.也增加了系統(tǒng)的可靠性和穩(wěn)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(shù)也都采取了熱備用..所有的模擬量都采取了和現(xiàn)場(chǎng)信號(hào)的光電隔離,所有的現(xiàn)場(chǎng)信號(hào)均通過(guò)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-SC42NS-4塊.另外，報(bào)表打印機(jī)一臺(tái)。
