年產(chǎn)18萬噸丙烯及54萬噸環(huán)氧丙烷項目物料平衡計算書

XXXX年產(chǎn)18萬噸丙烯-54萬噸環(huán)氧丙烷項目-物料平衡計算書第一章物料平衡計算書1.1概述本項目利用進口丙烷為主要原料合成乙烯，最終可制得純度為99.9%的聚合級丙烯，同時聯(lián)產(chǎn)純度為99.9%的環(huán)氧丙烷。在確定整個工藝流程后，經(jīng)AspenPlus的全流程模擬，獲得了更為準(zhǔn)確的數(shù)據(jù)，由定型階段轉(zhuǎn)為定量階段。通過對整個生產(chǎn)系統(tǒng)、生產(chǎn)車間，以及部分重要的生產(chǎn)單元進行物料衡算計算出主、副產(chǎn)品的產(chǎn)量，原材料的消耗定額，“三廢”排放量及組成，以及產(chǎn)品收率等各項經(jīng)濟技術(shù)指標(biāo)，從而定量地評述初步設(shè)計所選擇的工藝路線、生產(chǎn)方法及工藝流程在經(jīng)濟上是否合理，技術(shù)上是否先進，為后階段的設(shè)計提供數(shù)據(jù)。1.2物料衡算的原理和準(zhǔn)則物料衡算是以質(zhì)量守恒定律為基礎(chǔ)，對物料平衡進行的計算。物料平衡是指“在單位時間內(nèi)進入系統(tǒng)的全部物料質(zhì)量必定等于離開該系統(tǒng)的全部物料質(zhì)量再加上損失掉的和積累起來的物科質(zhì)量”。進行物料衡算時，先必須確定衡算的體系。對于已經(jīng)達到穩(wěn)定的體系，通常滿足以下關(guān)系：（進料量之和）-（出料量之和）=（系統(tǒng)累積量）當(dāng)系統(tǒng)中有化學(xué)反應(yīng)時可表示為：（進料量之和）-（出料量之和）+（反應(yīng)消耗量）-（反應(yīng)生成量）=（系統(tǒng)累積量）利用以上兩個關(guān)系，可以對整個工藝系統(tǒng)或子系統(tǒng)進行物料衡算。物料衡算包括總質(zhì)量衡算、組分衡算和元素衡算。各種衡算方法的適用情況如下表所示：表1.1物料衡算式適用范圍類別物料衡算形式無化學(xué)反應(yīng)有化學(xué)反應(yīng)總衡算式總質(zhì)量衡算式適用適用總物質(zhì)的量衡算式適用不適用組分衡算式組分質(zhì)量衡算式適用不適用組分物質(zhì)的量衡算式適用不適用元素原子衡算式元素原子質(zhì)量衡算式適用適用元素原子物質(zhì)的量衡算式適用適用由于系統(tǒng)中存在化學(xué)反應(yīng)，我們主要采用總質(zhì)量衡算的的衡算方法，同時列出每種物料組分的質(zhì)量流量便于查找和計算。1.3總項目核算從原料入廠到產(chǎn)品輸出，其工藝路線可分為如下兩個工段：丙烷脫氫工段和丙烯還氧化工段。1.3.1物料衡算任務(wù)對于本廠，工藝采取年開工300天（7200小時）的連續(xù)操作，其中一年內(nèi)的四~五周（約30天）用于固定的停車設(shè)備檢修及緊急情況處理。物料衡算的主要任務(wù)在于：① 確定對丙烯、環(huán)氧丙烷以及副產(chǎn)品的實際產(chǎn)量以及質(zhì)量指標(biāo)；② 確定丙烷、甲醇、過氧化氫等主要物料的消耗量以及損失率等指標(biāo)；③ 確定工藝中的“三廢”排放量等公共經(jīng)濟指標(biāo)；④ 各主要單元過程的物料衡算，并指導(dǎo)工藝設(shè)備的尺寸確定；⑤ 匯總?cè)鞒涛锪虾馑悖瑪?shù)據(jù)用于完成物料流程圖等后續(xù)設(shè)計任務(wù)。
