物料衡算書(shū)XXX石化年產(chǎn)60萬(wàn)噸丙烯和26萬(wàn)噸乙醇項(xiàng)目物料衡算書(shū)目錄1.1總述 物料衡算書(shū)1.1總述本項(xiàng)目中采用UOP公司丙烷脫氫制丙烯工藝，并利用副產(chǎn)的氫氣生產(chǎn)無(wú)水乙醇，最終得到純度為99.6%（W）的丙烯，年產(chǎn)量為60萬(wàn)噸，并聯(lián)產(chǎn)26萬(wàn)噸，純度為99.98%（W）的無(wú)水乙醇。在項(xiàng)目前期，確定了該生產(chǎn)所采用的工藝與流程后，需要進(jìn)一步對(duì)該項(xiàng)目進(jìn)行定量計(jì)算。通過(guò)對(duì)整個(gè)生產(chǎn)系統(tǒng)、生產(chǎn)工段、以及各個(gè)重要的生產(chǎn)單元進(jìn)行詳細(xì)的物料衡算，計(jì)算得到各個(gè)產(chǎn)品的實(shí)際產(chǎn)量與規(guī)格，各個(gè)原料的實(shí)際消耗定額，“三廢”的排放量及組成，從而定量的評(píng)述初步設(shè)計(jì)階段所采用的生產(chǎn)工藝是否合理，先進(jìn)，并通過(guò)衡算所得數(shù)據(jù)，來(lái)進(jìn)一步對(duì)各個(gè)階段所采用的設(shè)備進(jìn)行初步設(shè)計(jì)。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(duì)物料平衡進(jìn)行的計(jì)算。物料平衡是指“在單位時(shí)間內(nèi)進(jìn)入系統(tǒng)的全部物料質(zhì)量必定等于離開(kāi)該系統(tǒng)的全部物料質(zhì)量再加上損失掉的和積累起來(lái)的物科質(zhì)量”。進(jìn)行物料衡算時(shí)，先必須確定衡算的體系。對(duì)于已經(jīng)達(dá)到穩(wěn)定的體系（進(jìn)料量之和）-（出料量之和）=（系統(tǒng)累積量）利用上述關(guān)系，可以對(duì)整個(gè)工藝系統(tǒng)或子系統(tǒng)進(jìn)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)量衡算式適用不適用元素原子物質(zhì)的量衡算式適用不適用由于系統(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(shí)列出每種物料組分的質(zhì)量流量便于查找和計(jì)算。1.3物料衡算任務(wù)從原料入廠到產(chǎn)品輸出，本項(xiàng)目主要工藝路線可分為如下7個(gè)工段：原料預(yù)處理工段、丙烷脫氫反應(yīng)工段、急冷分氫工段、深冷分氫工段、丙烯精制工段、酯化加氫工段、乙醇水預(yù)精餾工段、乙醇精制工段。對(duì)于本分廠，采取年開(kāi)工333天（8000小時(shí)）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(chē)設(shè)備檢修及緊急情況處理。物料衡算的主要任務(wù)在于：確定丙烯、乙醇等產(chǎn)品的實(shí)際產(chǎn)量以及質(zhì)量指標(biāo)；確定乙二醇、乙酸、丙烷和氫氣的循環(huán)量以及損失率等指標(biāo)；確定工藝中的“三廢”排放量等公共經(jīng)濟(jì)指標(biāo)；各主要單元過(guò)程的物料衡算，并指導(dǎo)工藝設(shè)備的尺寸確定；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(jì)任務(wù)1.4工段物料數(shù)據(jù)1.4.1原料預(yù)處理工段1原料預(yù)脫C4塔（T0101）表1-2原料預(yù)脫C4塔進(jìn)出料流股條件表項(xiàng)目進(jìn)料出料1出料2溫度，℃144587壓力，MPa1.601.551.60氣相分率000表1-3原料預(yù)脫C4塔物料衡算表組分質(zhì)量流率kg/hr質(zhì)量分率進(jìn)料出料1出料2進(jìn)料出料1出料2丙烷3466503464581910.96870.97570.0690丙烯7957795700.02220.02240.0000乙烯0000.00000.00000.0000甲烷333300.00010.00010.0000氫氣0000.00000.00000.0000乙烷56956900.00160.00160.0000水0000.00000.00000.0000正丁烷54405440.00150.00000.1964異丁烷2036220340.00570.00000.7345丙炔515100.00010.00010.00001.4.2丙烷脫氫反應(yīng)工段1.丙烷脫氫反應(yīng)器（R0201,R0202，R0203，R0204）表1-4丙烷脫氫反應(yīng)器進(jìn)出流股條件表項(xiàng)目進(jìn)料出料溫度，℃600572壓力，MPa0.150.15氣相分率11表1-5丙烷脫氫反應(yīng)器物料衡算表組分質(zhì)量流率kg/hr質(zhì)量分率進(jìn)料1出料進(jìn)料1出料丙烷3464582615720.72230.5453丙烯7957858650.01660.1790乙烯01900.00000.0004甲烷3310530.00010.0022氫氣036580.00000.0076乙烷56922790.00120.0048水1246161246160.25980.2598正丁烷000.00000.0000異丁烷220.00000.0000丙炔514520.00010.00091.4.3急冷壓縮工段1.急冷器(V0301)表1-6急冷器進(jìn)出流股焓條件表項(xiàng)目進(jìn)料進(jìn)料2出料溫度，℃57230301壓力，MPa0.150.150.15氣相分率101表1-7急冷器物料衡算表組分質(zhì)量流率kg/hr質(zhì)量分率進(jìn)料出料1出料2進(jìn)料出料1出料2丙烷26157202615720.54530.00000.4333丙烯858650858650.17900.00000.1422乙烯19001900.00040.00000.0003甲烷1053010530.00220.00000.0017氫氣3658036580.00760.00000.0061乙烷2279022790.00480.00000.0038水1246161246162486160.25981.00000.4118正丁烷0000.00000.00000.0000異丁烷2020.00000.00000.0000丙炔45204520.00090.00000.00072.汽液分離器（V0302）表1-8汽液分離器進(jìn)出流股條件表項(xiàng)目進(jìn)料出料1出料2溫度，℃303030壓力，MPa0.150.150.15氣相分率0.4310表1-9汽液分離器物料衡算表組分質(zhì)量流率kg/hr質(zhì)量分率進(jìn)料出料1出料2進(jìn)料出料1出料2丙烷26157226157200.43330.72860.0000丙烯858658586400.14220.23920.0000乙烯19019000.00030.00050.0000甲烷1053105300.00170.00290.0000氫氣3658365800.00610.01020.0000乙烷2279227900.00380.00630.0000水24861639582446570.41180.01101.0000正丁烷0000.00000.00000.0000異丁烷2200.00000.00000.0000丙炔45245200.00070.00130.00003.多級(jí)壓縮機(jī)（C0301）表1-10多級(jí)壓縮機(jī)進(jìn)出流股條件表項(xiàng)目進(jìn)料出料1出料2出料3出料4溫度，℃3000040壓力，MPa0.150.000.000.003.14氣相分率10000.38表1-11多級(jí)壓縮機(jī)物料衡算表組分質(zhì)量流率kg/hr質(zhì)量分率進(jìn)料出料1出料2出料3出料4進(jìn)料1出料1出料2出料3出料4丙烷2615720002615720.72860.00000.00000.00000.7286丙烯85864000858640.23920.00000.00000.00000.2392乙烯1900001900.00050.00000.00000.00000.0005甲烷105300010530.00290.00000.00000.00000.0029氫氣365800036580.01020.00000.00000.00000.0102乙烷227900022790.00630.00000.00000.00000.0063水395800039580.01100.00000.00000.00000.0110正丁烷000000.00000.00000.00000.00000.0000異丁烷200020.00000.00000.00000.00000.0000丙炔4520004520.00130.00000.00000.00000.00134.干燥器（DRY）表1-12進(jìn)出干燥器流股條件表項(xiàng)目進(jìn)料出料1出料2溫度，℃404040壓力，MPa3.143.143.14氣相分率0.380.40表1-13干燥器物料衡算表組分質(zhì)量流率kg/hr質(zhì)量分率進(jìn)料出料1出料2進(jìn)料出料1出料2丙烷26157226157200.72860.73670.0000丙烯858648586400.23920.24180.0000乙烯19019000.00050.00050.0000甲烷1053105300.00290.00300.0000氫氣3658365800.01020.01030.0000乙烷2279227900.00630.00640.0000水3958039580.01100.00001.0000正丁烷0000.00000.00000.0000異丁烷2200.00000.00000.0000丙炔45245200.00130.00130.00001.一級(jí)閃蒸罐（V0303）表1-14一級(jí)深冷閃蒸罐進(jìn)出流股條件表項(xiàng)目進(jìn)料出料1出料2溫度，℃-30-30-30壓力，MPa3.143.143.14氣相分率0.1801表1-15一級(jí)深冷閃蒸罐物料衡算表組分質(zhì)量流率kg/hr質(zhì)量分率進(jìn)料出料1出料2進(jìn)料出料1出料2丙烷26157225784137310.73670.74580.3996丙烯858648430615590.24180.24380.1669乙烯190168220.00050.00050.0024甲烷10535654890.00300.00160.0523氫氣365829933590.01030.00090.3597乙烷227921081710.00640.00610.0183水0000.00000.00000.0000正丁烷0000.00000.00000.0000異丁烷2200.00000.00000.0000丙炔45244570.00130.00130.00082二級(jí)深冷閃蒸罐（V0304）表1-16二級(jí)深冷閃蒸罐進(jìn)出流股條
