煤干燥 AspenPlus 教程基于 AspenPlusV8.8 自带 help 文件整理编写一、整体思路:1.1 简易流程说明DRY-REAC 采用 Rstoic 模块,选用绝热反应器DRY-FLSH 采用 FLASH2 模块,由于 Rstoic 模块物流出口只有一个,该模块用于模拟干燥后的干煤和废气的分离;二、全局设定2.1 全局物流类型选择 MIXCIPSDMIXCIPSDfortheglobalStreamclassFlowBasis 选择 Mass 即质量基准三、定义物流3.1WET-COAL输入 WET-COAL 的工业分析、元素分析和全硫分析A■匚 omponenthtt「ibLit 亡©PROXANALComponentIChAttributeID:4.2 定义:DRY-REACElementValueAsh9.2Carbon67.1Hydrogen4.8Nitrogen1.1Chlorine0.1Sulfur1.3Oxygen16.4ElementValuePyritic0.6Sulfate0.1Organic0.6说明:Thevaluesmeetthefollowingconsistencyrequirements:•SULFANALvaluessumtotheULTANALvalueforsulfur.•ULTANALvalueforashequalsthePROXANALvalueforash.•ULTANALvaluessumto100.•PROXANALvaluesforFC,VM,andASHsumto100.四、定义 BLOCKS4.1 定义:DRY-FLSH 给定压力:PRESSURE"*绝热分离:DUTY=0给定压力:PRESSURE=**绝热脱水:HEATDUTY=04.3 定义 REACTIONS:COAL(wet)T°.0555084HO2说明:AspenPlustreatsallnonconventionalcomponentsasiftheyhaveamolecularweightof1.0.Thereactionindicatesthat1mole(or1lb.)ofcoalreactstoform0.0555084mole(or1lb.)ofwater.ComponentCoefficientCOAL|y]-1ComponentCoefficientH2O0»0555084Molarextent:Ibmotflir[x]|电 Fractionialconversion:0・2ofcomponent这里的 1 也是初值,后面的 Calculatorblock 有计算公式和水分输入,所以也不必纠结于此。五、UsingaCalculatorBlocktoControlDryingThematerialbalanceequationsforthisprocessdefinerelationsbetweenthefollowingquantities:•Watercontentofthefeedcoal.•Fractionalconversionofcoaltowater.•Watercontentofthedriedcoal.⑴-:"EdiLStoichiome^ReactionNmCOAL说明:ThefractionconversionofCoalof0.2isatemporaryvaluethatyouwilloverridelaterwithaCalculatorblock.-ReactantsProductsA转化率 0.2 只是一个初始值,后面的 Calculatorblock 有计算公式和水分输入,所以不必纠结于此。4.4 定义干煤的含水量说明:IntheMoisturefield,enteravalueof1.(Themoisturecontentof1isatemporaryvaluethatyouwilloverridelaterwithaCalculatorblock.)...
