Aspen plus简介与经济评估中的应用实例

Aspenplus简介与经济评估中的应用实例SchoolofChemicalEngineeringZhengzhouUniversityReporter:WangShilei内容Aspen简介应用例子1–评估论证会用到应用例子2–甲醇生产的灵敏度分析应用例子3-经济评价Aspen简介1.ASPEN（AdvancedSystemforProcessEngineering）其作为流程模拟与优化软件，不仅能模拟不同的工艺流程并给出详细的热量和物料衡算结果，而且还能估计设备大小和提供投资、操作费用及进行经济可行性的初步估算，最新版本为AspenOneV7.2。2.新版本的AspenPlus模块可以方便的调用NIST数据库进行物性查询和估算。总体而言，AspenPlus模拟是基于静态的，需使用Dynamics才能完成相应的动态模拟。另外，使用该模块的灵敏度分析以及优化子功能，可以方便的进行工况变化分析和寻优。3.ExchangerDesignandRating模块可以对各种类型的换热器进行设计和模拟，并对换热网络做进一步的优化分析。4.EconomicEvaluation模块包括AspenProcessEconomicAnalyzer、AspenIn-PlantCostEstimator、AspenCapitalCostEstimator这三个组件，对于旧版本的Aspen中，该模块名为AspenIcarusProcessEvaluator（AspenIPE）。这个模块除了作为独立的组件使用外，还在内置AspenPlus中使用，可用于：1）进行设备的精确尺寸和费用估算；2）进行初步的机械设计；3）估算购置和安装费用、间接费用和总投资、完成工程设计-订货-建设的计划日程表和利润率分析。应用例子1–评估论证会用到图为NREl进行技术经济评价流程，可以看到：物料衡算与能量衡算会用到Aspenplus；设备估算会用到Icarus（现为Aspen中的economicevaluation模块）应用例子2–甲醇生产的灵敏度分析（本例子的目的1.Aspen使用入门2.灵敏度分析功能简介）第一步：将实际的工艺流程转化为软件中的模块流程（红线为QQ截图临时添加，原料气经压缩换热进入反应，产物冷却后分离）应用例子2–甲醇生产的灵敏度分析第二步：依次完成组分输入，进料条件设定，以及其他塔器的设定。应用例子2–甲醇生产的灵敏度分析-组分输入应用例子2–甲醇生产的灵敏度分析-进料条件设置应用例子2–甲醇生产的灵敏度分析-塔器设定部分，以合成塔为例第三步：点击运行，得到输出结果应用例子2–甲醇生产的灵敏度分析需要什么样的输出结果，可以在下面的界面设置输出结果的表格形式甲醇合成分离StreamID123COMPOUTCOOL-OUTFEEDMETHANOLOUTPURGEREAC-OUTREACT-INRECYCLESEP1-OUTSEP2-OUTFromSEP1SPLITTERE1COMPCOLLERSEP2REACTORMIXERREACTORE1SPLITTERSEP1SEP2ToSEP2MIXERCOLLERE1SEP1COMPE1REACTORCOMPSPLITTERMIXERPhaseLIQUIDVAPORVAPORVAPORMIXEDVAPORLIQUIDMISSINGVAPORVAPORVAPORVAPORVAPORVAPORSubstream:MIXEDMoleFlowkmol/hrCO.19641406.739854315.8046970.5694315.8046660.6900.01887450.06.917394315.8046970.5694309.8794315.6082.1775395CO210.419476.810105329.3173393.3589329.317379.360008.8826670.08.346903329.3173393.3589313.9989318.89791.536798H21.180659106.21984975.1516476.8054975.1511615.550.04522450.0107.35524975.1516476.8054861.2554973.9701.135434CH4.35775802.324130109.1902109.1902109.19023.400000.12978100.02.552107109.1902109.1902105.7902108.8324.2279770N2.71301019.450544443.2551443.2551443.255113.24000.15395970.010.00959443.2551443.2551430.0151442.5421.5590504H2O64.01473.024815765.176781.13533065.176780.064.008320.0.031224065.176781.1353301.1353301.1620526.40831E-3CH40717.7747.9815912763.739844.93367763.73980.0717.52840.01.227871763.739844.9336744.9336745.96513.2462799MoleFracCO2.47168E-4.0508473.0451044.1150066.0451044.27850892.38686E-50.0.0506990.0451044.1150066.0510761.0508473.0456459CO2.0131119.0513773.0470343.0466106.0470343.0334536.01123290.0.0611762.0470343.0466106.0517551.0513773.3951158H21.48575E-3.8013513.7105699.7674624.7105699.68102305.71907E-50.0.7868292.7105699.7674624.8012607.8013513.2919239CH44.50205E-4.0175338.0155949.0129383.01559491.43325E-31.64120E-40.0.0187049.0155949.0129383.0174369.0175338.0586136N28.97255E-4.0712975.0633073.0525230.06330735.58122E-31.94697E-40.0.0733624.0633073.0525230.0708776.0712975.1437337H2O.08055641.87217E-49.30880E-31.34530E-49.30880E-30.0.08094450.02.28848E-49.30880E-31.34530E-41.87132E-41.87217E-41.64760E-3CH40.90325137.40540E-3.10908025.32437E-3.10908020.0.90738260.08.99933E-3.10908025.32437E-37.40623E-37.40540E-3.0633193MassFlowkg/hrCO5.501635188.78608845.81427186.048845.81418506.19.52868290.0193.75908845.81427186.048679.8478840.3124.972952CO2458.5586299.711414493.1917311.6514493.193492.618390.92440.0367.345514493.1917311.6513819.0314034.6367.63415H22.380066214.126310029.3113056.4610029.313256.755.09116720.0216.415210029.3113056.469799.70710026.932.288899CH45.73942637.285461751.7121751.7121751.71254.545382.0820450.040.942851751.7121751.7121697.1661745.9723.657381N219.97389264.742612417.1212417.1212417.12370.89854.3129460.0280.403612417.1212417.1212046.2212397.1415.66095H2O1153.243.44706291174.17820.453281174.1780.01153.1280.0.56251041174.17820.4532820.4532820.93468.1154475CH4022999.0531.4523024471.871439.77224471.870.022991.160.039.3436424471.871439.7721439.7721472.8227.891340MassFracCO2.23240E-4.1821290.1208722.3714792.1208722.72061782.15418E-5.1701472.1208722.3714792.1827252.1821290.0486489CO2.0186069.2891429.1980399.2365522.1980399.1360000.0159286.3225803.1980399.2365522.2909135.2891429.6616456H29.65762E-5.2065757.1370439.1784079.1370439.12681573.71471E-6.1900426.1370439.1784079.2063001.2065757.0223916CH42.32889E-4.0359706.0239359.0239359.02393592.12396E-38.48352E-5.0359535.0239359.0239359.0357281.0359706.0357791N28.10482E-4.2554072.1696717.1696717.1696717.01444251.75736E-4.2462332.1696717.1696717.2535929.2554072.1532066H2O.04679524.31298E-4.01604432.79481E-4.01604430.0.04698544.93962E-4.01604432.79481E-44.30576E-44.31298E-41.12939E-3CH40.9332346.0303432.3343920.0196735.33439200.0.9368001.0345491.3343920.0196735.0303095.0303432.0771987TotalFlowkmol/hr794.6568132.55087001.6358439.2487001.6352372.240790.76730.0136.44037001.6358439.2486067.0086206.9783.889487TotalFlowkg/hr24644.451036.55173183.1973183.2073183.1925681.0124542.230.01138.77273183.1973183.2047502.1948538.74102.2211TotalFlowcum/hr31.5249573.005304647.7805216.2413450.1562025.68031.325610.0710.27616147.0096808.4473345.6253418.63120.05987TemperatureK313.1500313.1500400.5906379.9969313.15003
