氯苯作為一種重要的有機合成原料，在生產(chǎn)上應用廣泛。由苯液相氯化法制得的氯苯中含有一定量的苯。本設計為一座連續(xù)精餾塔，用來分離易揮發(fā)的苯和不易揮發(fā)的氯苯。本設計主要完成了工藝計算和設備設計兩個方面的內(nèi)容， 經(jīng)物料衡算和熱量衡算 確定了塔高 、塔徑 1800mm、 板間距 500mm、 操作彈性 。在此基礎上，對輔助設備如全凝器、再沸器進行了簡單計算和核算，并初步選定規(guī)格。同時繪制了塔設備圖和帶控制點的工藝流程圖，并設置了控制點合適的自動控制裝置。 關鍵詞： 氯苯 精餾 篩板塔 II Design of 6000t/a of Chlorobenzene Refining Section Abstract： As a significant synthetic anic raw
