2、計算出主、副產品的產量，原材料的消耗、“三廢”排放量及組成，以及產品收率等各項經濟技術指標，從而定量地評述初步設計所選擇的工藝路線、生產方法及工藝流程在經濟上是否合理。1.2 物算目的工藝設計中，物算是在工藝流程確定后進行的。目的是根據原料與產品之間的定量轉化關系，計算原料的消耗量，各種中間產品、產品和副產品的產量，生產過程中各階段的消耗量以及組成，進而為熱量、其他工藝計算及設備計算打基礎。對于已有裝置，物算可以弄清原料的來龍去脈，找出生產中的薄弱環(huán)節(jié)，為改進生產、完善管理提供可靠的依據和明確方向，并可作為檢查原料利用率及三廢處理完善程度的一種。1.3 物物算方法算是根據質量守恒定律，利用某進

3、出化工過程中某些已知物流的流量和組成，通過建立有關物料的平衡式和約束式，求出其他未知物流的流量和組成的過程。系統(tǒng)中物料一般表達式為：系統(tǒng)中的積累=輸入-輸出+生成-消耗式中，生成或消耗項是由于化學反應而生成或消耗的量;積累量可以是正值，也可以是負值，當系統(tǒng)中積累量不為零時稱為非穩(wěn)定狀態(tài)過程；積累量為零時，稱為穩(wěn)定狀態(tài)過程。穩(wěn)定狀態(tài)過程時，可以簡化為：輸入=輸出-生成+消耗對無化學反應的穩(wěn)定過程，又可表示為：輸入=輸出物所示：算包括總質量、組分和元素。各種方法的適用情況如表 1-1表 1-1 物算式適用范圍類別物算形式無化學反應有化學反應總式適用總物算式適用總物質的量式適用不適用1.4 原料預處
