煤气化工艺技术分析

39于光元,李亚东(河南省中原大化集团有限责任公司煤气化项目组,河南濮阳,457004):从2种典型的煤气化工艺技术出发,比较了水煤浆进料方式与干粉进料方式的差异对气化整体性能的影响分析了水煤浆气化与粉煤气化不同的工艺特点工艺流程及关键设备,得出干粉进料方式避免了水煤浆进料方式因水气化升温带来的能量损失,采用的喷嘴分布方式更灵活,最后通过这2种气化技术的主要性能参数进一步说明了粉煤气化技术的优越性:煤化工;煤气化;Shell工艺;Texaco工艺:TQ54:A:1006-6772(2005)04-0039-05:2005-08-05:(1973)),,,,1995,10t,,,,,,COH2,,[1]2080,,,,,,,,,3,,(C0+H2),,:(DlVlE)3,,1,,,:Texaco()Dow;Shell()SCGPTexacoShellTexacoTCGP[2,3],15t/d1948MONTEBELLO1958MONGANTOWN100t/d,218MPa,,Texaco,,,,2080,2090402005114Shell(SCGP)Shell2070[4]1978,150t,,1987DeerPark250~400t,15000h,,1Texaco()2211水煤浆气化工作原理及工艺流程–6mm,60%?2%,9916%(3184MPa,1400e),CO+H2,3:,,;,,COCO2,,CO2,COH2;,CO2COH2,,Texaco,,Texaco,1,[3],,,,,,,,212粉煤制气工作原理及工艺流程,(H2CO);O2,1500e900e,1mg/m3,41,,,011mm,100%,,,SCGP[5],,,99%,2000e,22Shell(),,1500e900e,,1mg/m33311水煤浆气化关键设备TexacoTex-aco7[6],3,13,2,30m/s,,,,,,,Texaeo312粉煤气化关键设备Shell3[7].3,,;,;,900e,--,,4TexacoShell2,2Texaco422005114,20%;Shell,Shell,Texaeo,,Shell411Texaeo水煤浆气化工艺的特点,,,,;;,,,,;(CO+H2)80%~82%,,,,011%,,;,215~615MPa,410MPa,;98%;3,,114,,,,,,412Shell煤粉气化技术的特点,,Shell:,,,;,,,,,,,;,99%;ShellTexaco,10%,15%~25%(CO+H2)93%;Shell,,,,,12,,ShellTexaco,,Shell[4,6,7~9]5(1)ShellSCGP,,;,,,1300~1700e,,43,99%,,(2)Texaco,(3),:[1],1[J].,2001,29(3):193~200.[2]1CO[J]1,1998,23(1):40~44.[3]1[J]1,2001,109(1):46~49.[4]1[J]1,2000,90(1):16~19.[5],,1[J]1,2003,22(9):998~999.[6],,1[J]1,2004,5:9~11.[7]1[J]1,2003,3(5):11~13.[8]1[J]1,2003,4:37~38.[9],,,1IGCC[J]1,2003,24(1):1~4.AnalysisofCoalGasificationTechnologyYUGuang-yuan,LIYa-dong(ZhongyuanDahuaGroupCo1Ltd1HenanProvince,Puyang457004,China)Abstract:Itwasintroducedtwokindsofrepresentativecoalgasificationprocesses1TheTexacoconfigurationusingslurrycoalfeedgasifierandShellconfigurationwithdrycoalfeedgasifierwerecomparedforfindingaffectiontoto-talgasificationperformance1Differenttechnicalfeaturesandcriticalequipmentarealsoanalyzed1Thedryfeedmethodavoidlosingenergyforgasifiedwater,andmoreflexibledistributionofnozzlethanthecoalwaterslurryfeedmethodwereilluminated1Finally,describedtheShellprocesshadmoreadvantagethanTexacoprocessbysomeprimaryperformanceparameters1Keywords:coalchemicalindustry;coalgasification;Shellprocess;Texacoprocess12006年洁净煤技术杂志征订工作已经开始,请还未订阅的广大作者及读者及时订阅,以免耽误你及时收到本刊订刊电话:[phone]洁净煤技术编辑部2005年11月
