I-Craft Breweries isebenzisa i-CO2 kwinani elimangalisayo lezicelo kwi-brewing, ukupakisha kunye nenkqubo yokukhonza: ukuhambisa ibhiya okanye imveliso kwi-tank ukuya kwi-tank, i-carbonizing imveliso, ukucoca i-oksijini ngaphambi kokupakisha, ukupakisha ibhiya kwinkqubo, i-pre-flushing brit tanks emva kokucoca. kunye nokucoca, ukufaka ibhotile yebhiya eyilwayo kwindawo yokutyela okanye ibha.Oku kuphela kwabaqalayo.
"Sisebenzisa i-CO2 kulo lonke i-brewery kunye ne-bar," kusho uMax McKenna, umphathi ophezulu wentengiso kwi-Boston-based Dorchester Brewing Co. Ukukhonza ubhiya - kuzo zonke izigaba zenkqubo.”
Njengamashishini amaninzi e-craft, i-Dorchester Brewing ijongene nokunqongophala komgangatho wezorhwebo we-CO2 ekufuneka isebenze (funda malunga nazo zonke izizathu zolu nqongophala apha).
"Ngenxa yezivumelwano zethu, ababoneleli bethu be-CO2 bangoku abazange baphakamise amaxabiso abo nangona ukunyuka kwexabiso kwezinye iindawo zemarike," kusho uMcKenna.Ukuza kuthi ga ngoku, impembelelo ibisoloko ikukusasazwa okulinganiselweyo.
Ukuhlawulela ukungabikho kwe-CO2, i-Dorchester Brewing isebenzisa i-nitrogen endaweni ye-CO2 kwezinye iimeko.
"Sikwazile ukuhambisa imisebenzi emininzi kwi-nitrogen," waqhubeka uMcKenna.“Ezinye zezona zibalulekileyo yayikukucoca iinkonkxa nokuvala igesi ngexesha lokunkonkxa nokutywinwa.Le yeyona nto yongezwa kakhulu kuthi kuba ezi nkqubo zifuna i-CO2 eninzi.Kangangexesha elide sasinesityalo esikhethekileyo se-nitro.Sisebenzisa ijenereyitha ekhethekileyo yenitrogen ukuvelisa yonke initrogen yebha - kumgca wenitro ozinikeleyo kunye nomxube wethu webhiya.
I-N2 yeyona rhasi ingabizi kakhulu ekwaziyo ukuvelisa kwaye ingasetyenziswa kumagumbi angaphantsi asezantsi, kwiivenkile zeebhotile nakwiibhari.I-N2 inexabiso eliphantsi kune-CO2 yeziselo kwaye ihlala ifumaneka ngakumbi, kuxhomekeke kubukho bendawo yakho.
I-N2 inokuthengwa njengegesi kwiisilinda zoxinzelelo oluphezulu okanye njengolwelo eDewars okanye iitanki ezinkulu zokugcina.I-nitrojeni inokuveliswa kwisiza kusetyenziswa ijenereyitha yenitrogen.Iijenereyitha zenitrogen zisebenza ngokususa iimolekyuli zeoksijini emoyeni.
I-nitrogen yeyona nto ininzi kakhulu (78%) kwi-atmosfera yomhlaba, enye i-oksijini kunye ne-trace gases.Ikwayenza ikhuseleke ngakumbi kokusingqongileyo njengoko ukhupha iCO2 encinci.
Xa kusetyenzwa kunye nokupakishwa, i-N2 ingasetyenziselwa ukugcina i-oxygen ngaphandle kwebhiya.Xa isetyenziswe ngokufanelekileyo (abaninzi abantu baxuba i-CO2 kunye ne-N2 xa besebenza ngebhiya ye-carbonated) i-N2 ingasetyenziselwa ukucoca iitanki, ukuhambisa ubhiya ukusuka kwitanki ukuya kwitanki, ukuxinzelela i-kegs ngaphambi kokugcinwa, ngelixa i-aerating phantsi kwee-caps.isithako sokungcamla kunye nokuvakala komlomo.Kwimivalo, i-nitro isetyenziswa kwimigca yamanzi etephu ye-nitropiv kunye noxinzelelo oluphezulu / izicelo zomgama omde apho i-nitrogen ixutywe nepesenti ethile ye-CO2 ukukhusela ibhiya ekuphumeni ugwebu kwimpompo.I-N2 ingade isetyenziswe njengendawo yokubilisa igesi yokukhupha amanzi ukuba oku kuyinxalenye yenkqubo yakho.
Ngoku, njengoko besitshilo kwinqaku lethu langaphambili malunga nokunqongophala kwe-CO2, i-nitrogen ayilona tshintsho oluchanekileyo lwe-CO2 kuzo zonke izicelo zotywala.Ezi gesi ziziphatha ngendlela eyahlukileyo.Zinobunzima obuhlukeneyo bemolekyuli kunye noxinaniso olwahlukeneyo.
Umzekelo, i-CO2 inyibilika ngakumbi kulwelo kune-N2.Kungenxa yoko le nto i-nitrogen inika amaqamza amancinci kunye ne-mouthfeel eyahlukileyo kwibhiya.Yiyo loo nto abenzi botywala besebenzisa amathontsi enitrogen engamanzi endaweni yegesi yenitrogen ukwenza ibhiya yenitrate.Ikharbon diokside yongeza intwana yobukrakra okanye ubumuncu obungenayo initrogen, nto leyo enokutshintsha incasa, abantu batsho njalo.Ukutshintshela kwinitrogen akusayi kuzicombulula zonke iingxaki zecarbon dioxide.
UChuck Skepek, umalathisi weenkqubo zobugcisa bokwenza utywala kwiBrewers Institute uthi: “Kukho, kodwa initrogen ayilonyango okanye isicombululo esikhawulezayo.I-CO2 kunye ne-nitrogen ziziphatha ngendlela eyahlukileyo.Uya kufumana initrogen eninzi exutywe nomoya osetankini kunokuba ucoca i-CO2.Ngoko kuya kufuna initrogen eninzi.Ndiyiva le nto ngokuphindaphindiweyo.
“Omnye umdidiyeli endimaziyo wayekrelekrele ngokwenene waza waqalisa ukukhupha ikharbon diokside esebenzisa initrogen, ibe ibhiya yabo yayineoksijini eninzi kuyo, ngoko ngoku basebenzisa umxube wenitrogen necarbon dioxide, benethamsanqa elingakumbi.hayi nje, “Heyi, siza kuqala ukusebenzisa initrogen ukusombulula zonke iingxaki zethu.Kuhle ukubona okuninzi malunga noku kuncwadi, siqala ukubona abantu abaninzi ngokwenene besenza uphando, kwaye, uyazi, ukuza nezona zenzo zolu tshintsho.
Ukuhanjiswa kwezi gesi kuya kwahluka njengoko zinokuxinana okungafaniyo okunokukhokelela kutshintsho oluthile lobunjineli okanye kugcino.Mamela uJason Perkins, umdidiyeli omkhulu e-Allagash Brewing Co., uxoxe ngokuphucula umgca wakhe webhotile kunye negesi eninzi ukuze asebenzise i-CO2 yokuzaliswa kwesitya ngoxinzelelo kunye ne-N2 ye-sealant kunye ne-bubble breaker.Ugcino lunokwahluka.
“Ngokuqinisekileyo kukho umahluko, ngokuyinxenye ngenxa yendlela esiyifumana ngayo initrogen,” utshilo uMcKenna.“Sifumana initrogen elulwelo esulungekileyo kwiidewars, ke ukuyigcina kwahluke kakhulu kwiitanki zethu zeCO2: zincinci, kwiirola kwaye zigcinwe kwisikhenkcisi.Siyibeke kwinqanaba elilandelayo.ikharbon diokside ukuya kwinitrogen, kodwa kwakhona, silumke kakhulu malunga nendlela yokwenza inguqu ngokufanelekileyo nangokuthembekileyo ukuqinisekisa ukuba ibhiya ikwinqanaba eliphezulu ngalinye lendlela.isitshixo, kwezinye iimeko yayiyiplagi elula kakhulu kunye nokutshintshwa komdlalo, ngelixa kwezinye iimeko ifuna ukuphuculwa okubalulekileyo kwizixhobo, iziseko zophuhliso, imveliso, njl.
Ngokweli nqaku libalaseleyo elivela kwi-Titus Co. (umthengisi weecompressor zomoya, ezomisi zomoya, kunye neenkonzo zokucinezela umoya ngaphandle kwePennsylvania), iijenereyitha zenitrogen zisebenza ngenye yeendlela ezimbini:
I-Pressure swing adsorption: I-Pressure swing adsorption (PSA) isebenza ngokusebenzisa i-carbon molecular sieves ukwahlula iimolekyuli.Isisefu sinemingxuma elingana neemolekyuli zeoksijini, zibamba ezo molekyuli njengoko zidlula kwaye zivumela iimolekyuli ezinkulu zenitrogen.Emva koko ijenereyitha ikhupha ioksijini kwelinye igumbi.Isiphumo sale nkqubo kukuba ukucoceka kwe-nitrogen kunokufikelela kwi-99.999%.
Ukuveliswa kwe-nitrogen kwi-membrane.Ukuveliswa kwenitrogen yeMembrane kusebenza ngokwahlula iimolekyuli kusetyenziswa imicu yepolymer.Ezi ntsinga zinomgongxo, zinemingxuma engaphezulu ukuze ikwazi ukudlula ioksijini, kodwa incinci kakhulu ukuba iiathom zenitrogen zisuse ioksijini kumsinga wegesi.Iijenereyitha ezisebenzisa le ndlela zinokuvelisa initrogen ukuya kuthi ga kwi-99.5% ecocekileyo.
Ewe, i-PSA nitrogen generator ivelisa initrogen esulungekileyo kwimithamo emikhulu kunye namazinga aphezulu okuhamba, olona hlobo lusulungekileyo lwenitrogen olufunwa ngabavelisi abaninzi.I-Ultrapure ithetha i-99.9995% ukuya kwi-99%.Iijenereyitha ze-nitrogen zeMembrane zifanelekile kwiimveliso ezincinci zotywala ezifuna umthamo ophantsi, enye indlela yokuhamba okuphantsi apho i-99% ukuya kwi-99.9% yobunyulu yamkelekile.
Ngokusebenzisa itekhnoloji yamva nje, iAtlas Copco nitrogen generator yicompressor yomoya yoshishino exineneyo enediaphragm ekhethekileyo eyahlula initrogen kumsinga womoya oxinanisiweyo.Iimveliso zokwenza utywala ngabaphulaphuli abaninzi ekujoliswe kubo kwi-Atlas Copo.Ngokwephepha elimhlophe le-Atlas Copco, abenzi botywala ngokuqhelekileyo bahlawula phakathi kwe-$0.10 kunye ne-0.15 ye-cubic foot ukuvelisa i-nitrogen kwindawo.Oku kuthelekiswa njani neendleko zakho zeCO2?
"Sinikezela ngeepakethi ezisemgangathweni ezintandathu ezigubungela i-80% yazo zonke ii-breweries - ukusuka kumawaka ambalwa ukuya kumakhulu amawaka emibhobho ngonyaka," utshilo uPeter Askini, umphathi wophuhliso lweshishini kwiigesi zeshishini kwi-Atlas Copco.“Indawo yokuthengisa utywala inokunyusa amandla ejenereyitha zayo zenitrogen ukuze ikhule ngelixa igcina ukusebenza kakuhle.Ukongeza, uyilo lwemodyuli luvumela ukuba kongezwe ijenereyitha yesibini ukuba umsebenzi weshishini lotywala uyanda kakhulu.”
U-Asquini uchaza athi: “Ukusebenzisa initrogen akwenzelwanga ukutshintsha ngokupheleleyo iCO2, kodwa sicinga ukuba abenzi bewayini banokunciphisa ukusetyenziswa kwabo malunga ne-70%.Amandla okuqhuba angundoqo kukuzinza.Kulula kakhulu kuye nawuphina umenzi wewayini ukuvelisa initrogen eyedwa.Musa ukusebenzisa iigesi ezininzi ze-greenhouse.”eyona nto ingcono kwimo engqongileyo Kuya kuhlawula ukususela kwinyanga yokuqala, eya kuchaphazela ngokuthe ngqo umgca ophantsi, ukuba ayibonakali ngaphambi kokuba uthenge, ungayithengi.Nantsi imithetho yethu elula.Imfuno ye-CO2 iyenyuka ngamandla ukuvelisa iimveliso ezinjalo, njengomkhenkce owomileyo, osebenzisa izixa ezikhulu zeCO2 kwaye ziyafuneka ukuthutha amayeza okugonya.Iibreweries e-US zivakalisa inkxalabo malunga nenqanaba lokubonelela kwaye bayazibuza ukuba banokugcina inqanaba lexabiso lihambelana neemfuno ze-brewery. "
Njengoko kukhankanyiwe ngaphambili, ukucoceka kwenitrogen kuya kuba yinkxalabo enkulu kubavelisi bezandla.Kanye njenge-CO2, i-nitrogen iya kusebenzisana nebhiya okanye i-wort kwaye iphathe ukungcola kunye nayo.Yingakho ukutya okuninzi kunye nesiselo se-nitrogen generators kuya kubhengezwa njengeeyunithi ezingenawo ioli (funda malunga neenzuzo zokucoceka kwe-oyile-free compressors kwisivakalisi sokugqibela kwi-sidebar engezantsi).
"Xa sifumana i-CO2, sijonga umgangatho kunye nokungcoliswa kwayo, enye inxalenye ebaluleke kakhulu yokusebenza nomthengisi olungileyo," kusho uMcKenna.“Initrojeni yahluke kancinane, yiyo loo nto sisathenga initrogen engamanzi.Enye into esijonge kuyo kukufumana kunye namaxabiso ejenereyitha yenitrogen yangaphakathi-kwakhona, kugxilwe kwinitrogen eyivelisayo ngePurity ukunqanda ukufunyanwa kweoksijini.Sibona oku njengotyalo-mali olunokwenzeka, ngoko ke iinkqubo kuphela kwi-brewery ezixhomekeke ngokupheleleyo kwi-CO2 ziya kuba yi-carbonation yebhiya kunye nokugcinwa kwamanzi ompompo.
"Kodwa enye into ebaluleke ngokwenene ukugcina engqondweni - kwakhona, into ebonakala ikhetha ukungahoywa kodwa ibalulekile ekugcineni umgangatho webhiya - kukuba nayiphi na ijeneretha ye-nitrogen kufuneka ivelise i-nitrogen kwindawo yesibini ye-decimal [okt 99.99% yococeko] ukunciphisa i-oksijini. ukuthathwa kunye nomngcipheko we-oxidation.Eli nqanaba lokuchaneka kunye nokucoceka lifuna iindleko zejenereyitha yenitrogen, kodwa liqinisekisa umgangatho wenitrogen kwaye ngoko umgangatho webhiya.
Abenzi botywala bafuna idatha eninzi kunye nolawulo lomgangatho xa usebenzisa initrogen.Ngokomzekelo, ukuba umqhubi usebenzisa i-N2 ukuhambisa ibhiya phakathi kwamatanki, ukuzinza kwe-CO2 kwitanki kunye ne-tank okanye ibhotile kufuneka kubekwe esweni kuyo yonke inkqubo.Kwezinye iimeko, i-N2 ecocekileyo ayinakusebenza ngokufanelekileyo (umzekelo, xa ugcwalisa izitya) kuba i-N2 ecocekileyo iyakususa i-CO2 kwisisombululo.Ngenxa yoko, abanye abavuzi baya kusebenzisa umxube we-50/50 we-CO2 kunye ne-N2 ukuzalisa isitya, ngelixa abanye baya kukuphepha ngokupheleleyo.
Ingcebiso ye-N2 Pro: Masithethe ngesondlo.Iijenereyitha ze-nitrojeni zisondele kakhulu "ukuyicwangcisa kwaye uyilibale" njengoko unokuzifumana, kodwa ezinye izinto ezisetyenziswayo, ezinjengezihluzi, zifuna ukutshintshwa kwe-semi-regular.Ngokuqhelekileyo, le nkonzo ifuneka malunga neeyure ezingama-4000.Iqela elifanayo elikhathalela icompressor yakho yomoya liya kukhathalela ijenereyitha yakho.Uninzi lweejeneretha ziza nomlawuli olula ofana ne-iPhone yakho kwaye zibonelela ngezakhono ezigcweleyo zokujonga usetyenziso olukude.
Ukucocwa kwetanki kuyahluka kwi-nitrogen yokucoca ngenxa yezizathu ezininzi.I-N2 ixuba kakuhle nomoya, ngoko ayidibani ne-O2 njengoko i-CO2 isenza.I-N2 ikwakhaphukhaphu kunomoya, ngoko igcwalisa itanki ukusuka phezulu ukuya ezantsi, ngelixa i-CO2 iyigcwalisa ukusuka ezantsi ukuya phezulu.Kuthatha i-N2 engaphezulu kune-CO2 ukucoca itanki yokugcina kwaye ihlala ifuna ukudutyulwa okungaphezulu.Ngaba usagcina imali?
Imiba emitsha yokhuseleko ikwavela ngerhasi entsha yemizi-mveliso.Indawo ethengisa utywala kufuneka ngokuqinisekileyo ifake i-O2 sensors ukuze abasebenzi bakwazi ukubona umgangatho womoya wangaphakathi - njengokuba une-N2 dewars egcinwe kwiifriji kwezi ntsuku.
Kodwa inzuzo inokugqithisa ngokulula izityalo zokubuyisela i-CO2.Kule webinar, i-Dion Quinn ye-Foth Production Solutions (inkampani yobunjineli) ithi imveliso ye-N2 ixabisa phakathi kwe-8 kunye ne-$ 20 ngetoni, ngelixa ibamba i-CO2 ngesityalo sokubuyisela iindleko phakathi kwe-$ 50 kunye ne-200 yeetoni.
Izibonelelo nitrogen generator ziquka ukuphelisa okanye ubuncinane ukunciphisa ukuxhomekeka kwizivumelwano kunye nonikezelo CO2 kunye nitrogen.Oku konga indawo yokugcina njengoko oomatshini botywala benokuvelisa kwaye bagcine kangangoko bakufunayo, kupheliswe imfuneko yokugcina nokuthutha iibhotile zenitrogen.Njengoko kunye ne-CO2, ukuthunyelwa kunye nokuphathwa kwe-nitrogen kuhlawulwa ngumthengi.Nge-nitrogenerator, oku akuseyongxaki.
Iijenereyitha ze-nitrogen zihlala zilula ukudibanisa kwindawo yotywala.Iijenereyitha zenitrogen ezincinci zinokuxhonywa eludongeni ukuze zingathathi indawo yomgangatho kwaye zisebenze ngokuzolileyo.Ezi ngxowa zibamba ngokutshintsha kwamaqondo obushushu ambient kakuhle kwaye zixhathisa kakhulu ekuguquguqukeni kobushushu.Inokufakwa ngaphandle, kodwa ayikhuthazwa kwimozulu ephezulu kunye nephantsi.
Baninzi abavelisi beejenereyitha zenitrogen kuquka iAtlas Copco, iParker Hannifin, iSouth-Tek Systems, iMilcarb kunye neHoltec Gas Systems.Ijenereyitha encinci ye-nitrogen inokubiza malunga ne-800 yeedola ngenyanga phantsi kwenkqubo yeminyaka emihlanu yokuqeshisa, utshilo u-Asquini.
"Ekupheleni kosuku, ukuba i-nitrogen ilungile kuwe, uneentlobo ezahlukeneyo zababoneleli kunye nobuchwepheshe onokukhetha kuzo," kusho u-Asquini.“Fumana ukuba yeyiphi ekulungeleyo kwaye uqiniseke ukuba uyiqonda kakuhle iindleko ezipheleleyo zobunini [ixabiso lilonke lobunini] kwaye uthelekise iindleko zamandla kunye nokugcina phakathi kwezixhobo.Uya kufumanisa ukuba ukuthenga ngexabiso eliphantsi akulunganga kumsebenzi wakho .
Iinkqubo zejenereyitha ye-nitrogen zisebenzisa i-compressor yomoya, kwaye uninzi lwee-craft breweries sele zinenye, esebenzayo.
Zeziphi iicompressor zomoya ezisetyenziswayo kwimizi yotywala?Utyhala ulwelo ngemibhobho namatanki.Amandla okuhambisa umoya kunye nokulawula.I-aeration yewort, igwele okanye amanzi.ivalve yokulawula.Khupha irhasi ukunyanzela udaka ukuba luphume eitankini ngexesha lokucoca kunye nokunceda ekucoceni imingxuma.
Izicelo ezininzi zotywala zifuna ukusetyenziswa okukhethekileyo kwe-100% yeecompressor zomoya ezingenawo ioli.Ukuba ioli idibana nebhiya, ibulala igwele kwaye igubungele i-foam, eyonakalisa isiselo kwaye yenze ibhiya ibe mbi.
Ikwangumngcipheko wokhuseleko.Ngenxa yokuba ishishini lokutya kunye nesiselo libuthathaka kakhulu, kukho umgangatho ongqongqo kunye nemigangatho yokucoceka endaweni, kwaye ngokufanelekileyo.Umzekelo: Sullair SRL series oyile-free air compressors ukusuka 10 ukuya 15 hp.(ukusuka kwi-7.5 ukuya kwi-11 kW) zifaneleke kakuhle kwimizi-mveliso yotywala.Abenzi botywala banandipha ukuzola kwezi ntlobo zoomatshini.Uthotho lwe-SRL lubonelela ngamanqanaba engxolo aphantsi ukuya kuthi ga kwi-48dBA, okwenza icompressor ilungele ukusetyenziswa kwangaphakathi ngaphandle kwegumbi elahlukileyo lesandi.
Xa umoya ococekileyo ubalulekile, njengakwimizi-mveliso yotywala nakwimizi-mveliso yokwenza utywala, umoya ongenaoyile ubalulekile.Amasuntswana e-oyile emoyeni oxinanisiweyo angangcolisa iinkqubo ezisezantsi kunye nemveliso.Ekubeni iindawo ezithengisa utywala ezininzi zivelisa amawaka emiphanda okanye iiseko eziliqela zebhiya ngonyaka, akukho bani unokukwazi ukububeka esichengeni.Iicompressors ezingenayo ioyile zifanelekile ngakumbi kwizicelo apho umoya unxibelelana ngqo ne-feedstock.Nakwizicelo apho kungekho nxibelelwano luthe ngqo phakathi kwezithako kunye nomoya, njengakwimigca yokupakisha, icompressor engenawo ioyile inceda ukugcina imveliso yokugqibela icocekile kuxolo lwengqondo.
