因大園廠節水績效卓越,廢水COD濃度高達2700ppm,用一般喜氣生物處理無法滿足放流水標準,進而採用UASB系統,先行厭氧處理,再行喜氣處理
計畫執行前：厭氧處理單元所產生之沼氣直接溢散於大氣
計畫執行後：厭氧處理單元所產生之沼氣經沼氣純化回收系統純化、收集後,進入鍋爐燃燒產生蒸汽並售予大園汽電共生廠
GHG減量效益：•減少甲烷直接溢散;•以回收之甲烷取代為產生蒸汽所耗用之化石燃料6背景描述低耗水量6.3M3/T高污染廢水濃度COD2700ppm厭氧處理系統UASB產生可當生質能源之沼氣CH4,C02,H2S(65000ppm)沼氣純化系統甲烷鍋爐產生蒸氣高濃度H2S造成燃燒塔腐蝕減量計畫早期處理措施7背景描述製程廢水進流快混及慢混厭氧處理調勻池加壓浮除池初沉池一級廢水處理系統放流水終沉池好氧處理二級廢水處理系統甲烷鍋爐沼氣純化系統計畫邊界8沼氣熱能回收減碳流程9監測設施相關位置BiogaspurificationsystemAnaerobicreactorNewlyinstalledboilerWastewaterBiogasBiogasMethaneMethaneSteamSteamPurificationsystemandboilerelectricitymetersSteamflowtransmittersMethanefractionanalyzerTYPMTYCwatertankFeedingFeedingwaterwaterFeedingwatertemperaturesamplingpointGasflowrate/temperature/pressuretransmittersWastewaterEffluentCustomerSteamtemperature/pressuretransmittersTYCSteampipeTYCSteampipeMonitoringequipmentlocationsProjectboundaryTYCBiogaspurificationsystemBiogaspurificationsystemAnaerobicreactorAnaerobicreactorNewlyinstalledboilerNewlyinstalledboilerWastewaterBiogasBiogasMethaneMethaneSteamSteamPurificationsystemandboilerelectricitymetersSteamflowtransmittersMethanefractionanalyzerTYPMTYCwatertankTYCwatertankFeedingFeedingwaterwaterFeedingwatertemperaturesamplingpointGasflowrate/temperature/pressuretransmittersWastewaterEffluentCustomerSteamtemperature/pressuretransmittersTYCSteampipeTYCSteampipeMonitoringequipmentlocationsProjectboundaryMonitoringequipmentlocationsProjectboundaryTYC10VCSPD撰寫項目1.DescriptionofProject2.VCSMethodology3.Monitoring4.GHGEmissionReduction5.EnvironmentalImpact6.StakeholdersComments7.Schedule8.Ownership11DescriptionofProject1.2Type/CategoryoftheprojectUndertheUNFCCCCleanDevelopmentMechanism(CDM)–aGHGprogramthathasbeenapprovedbytheVCSBoard,thisprojectfallsinto–Type(iii)otherprojectactivities:Methanerecoveryinwastewatertreatment;and–Type(i)renewableenergyprojectactivities:Thermalenergyfortheuserwithorwithoutelectricity1.3EstimatedamountofemissionreductionoverthecreditingperiodincludingprojectsizeTheprojectisexpectedtoreduceonaverage19,490tCO2eperyearoverthe10-yearcreditingperiod.12DescriptionofProject1.6Durationoftheprojectactivity/creditingperiod:•Projectstartdate:6thMay2005–WhichisthedatetheprojectactivitybeganreducingGHGemissions•Creditingperiodstartdate:1stJanuary2009•Projectoperationallifetime:30years1.7Conditionspriortoprojectinitiation:•Priortoprojectinitiation,thebiogasgenerationfromtheexistinganaerobicwastewatertreatmentsystemisdirectlyventedtotheatmosphere•Priortoreceivingsteamgeneratedbytheproject,TYCsupplied38MWofelectricityand100tonslow-pressuresteamperhourtocustomersinTa-YuanIndustrialPark13DescriptionofProject1.10Compliancewithrelevantlocallawsandregulationsrelatedtotheproject:•WastewaterEffluentStandards•Article24ofAirPollutionControlAct1.13Demonstrationthattheprojecthasnotcreatedanotherformofenvironmentalcredit(forexamplerenewableenergycertificates):•Theprojectactivityhasneithercreatedanotherformofenvironmentalcreditnorparticipatedinotherinternationalcarboncreditschemes14VCSMethodology2.1TitleandreferenceoftheVCSmethodologyappliedtotheprojectactivityandexplanationofmethodologychoices:•Version09ofAMS-III.H.“Methanerecoveryinwastewatertreatment”;and•Version13ofAMS-I.C.“Thermalenergyforuserwithorwithoutelectricity”2.4DescriptionofthebaselinescenarioThebaselinescenarioisthatbiogaswouldcontinuetobeventedwithoutpurificationandutilization,whilesteamwouldcontinuetobegeneratedbyusingfossilfuels15Additionality-ProjectTestStep1:RegularSurplusTheprojectisnotmandatedbyenforcedlaworregulationframeworkStep1:RegularSurplusTheprojectisnotmandatedbyenforcedlaworregulationframeworkStep2:ImplementationBarriersTheprojectshallfaceone(ormore)distinctbarriersStep3:CommonPractice•Projecttypeshallnotbecommonpracticeinsector/region•Ifitiscommonpractice,theprojectproponentsshallidentifybarriersfacedcomparedwithexistingprojectsTechnologicalBarriersProjectfacetechnology-relatedbarrierstoitsimplementationInvestmentBarriersProjectfacefinancialconstraintsthatcanbeovercamebytheadditionalrevenuesassociatedwiththegenerationofVCUsInstitutionalBarriersProjectfacefinancial,organizational,culturalorsocialbarriersthattheVCUrevenuestreamcanhelpovercome16Additionality2.5AssessmentanddemonstrationofadditionalityTheprojectadditionalityisdemonstratedbasedontheprojecttestasperVCS2007.Theprojecttestundergoes3steps:Step1:RegularSurplusTheprojectisnotmandatedbyanyenforcedlaw,statuteorotherregulatoryframeworkStep2:Imp
