概述本項(xiàng)目旨為中國石油化工股份有限公司天津石化設(shè)計(jì)一座年處理廢氣分廠，該項(xiàng)目以總廠產(chǎn)生的含硫廢氣為原料，通過酸性氣燃燒、克勞斯反應(yīng)、尾氣處理和液流脫氣四個工段，硫資源利用程度大大增加，最終得到質(zhì)量分?jǐn)?shù)為 99.3%的優(yōu)質(zhì)硫，以及副產(chǎn)中壓蒸汽。設(shè)計(jì)過程中利用Aspen Plus對全流程進(jìn)行模擬，并在此基礎(chǔ)上完成物料衡算、能量衡算，Aspen Plus模擬流程如圖1-1所示。圖1-1 全流程模擬圖2. 物料衡算原理系統(tǒng)的物料衡算以質(zhì)量守恒為理論基礎(chǔ)，研究某一系統(tǒng)內(nèi)進(jìn)出物料量及組成的變化，即：系統(tǒng)累計(jì)的質(zhì)量輸入系統(tǒng)的質(zhì)量輸出系統(tǒng)的質(zhì)量反應(yīng)生成的質(zhì)量反應(yīng)消耗的質(zhì)量假設(shè)系統(tǒng)無泄漏，有： 當(dāng)系統(tǒng)無化學(xué)反應(yīng)時，有： 在穩(wěn)定狀態(tài)下，有： ， 其中，-進(jìn)入系統(tǒng)的物料流率； -流出系統(tǒng)的物料流率； -反應(yīng)產(chǎn)生物料流率； -反應(yīng)消耗物料流率。3. 物料衡算通過對系統(tǒng)整體以及部分主要單元的詳細(xì)物料衡算，得到主、副產(chǎn)品的產(chǎn)量，原料的消耗量， “三廢”的排放量以及最后產(chǎn)品的質(zhì)量指標(biāo)等關(guān)鍵經(jīng)濟(jì)技術(shù)指標(biāo)，對所選工藝路線、設(shè)計(jì)流程進(jìn)行定量評述，為后階段的設(shè)計(jì)提供依據(jù)。4. 系統(tǒng)物料衡算4.1酸性氣燃燒工段物料衡算酸性氣燃燒工段流程模擬圖如下圖所示：圖4-1酸性氣燃燒工段模擬圖表4-1
