Ama-expander angasebenzisa ukunciphisa ingcindezi ukushayela imishini ezungezayo. Ulwazi lokuthi ungazihlola kanjani izinzuzo ezingaba khona zokufaka i-extender ingatholakala lapha.
Ngokujwayelekile embonini yezinqubo zamakhemikhali (CPI), "inani elikhulu lamandla liyachithwa kumavalvu okulawula ukucindezela lapho uketshezi olunamandla kufanele ludangele" [1]. Kuye ngezici ezihlukahlukene zobuchwepheshe nezomnotho, kungase kufiseleke ukuguqula la mandla abe amandla omshini ajikelezayo, angasetshenziswa ukushayela amajeneretha noma eminye imishini ezungezayo. Ngoketshezi olungenakucindezelwa (uketshezi), lokhu kufinyelelwa kusetshenziswa i-hydraulic energy recovery turbine (HPRT; bona inkomba 1). Oketshezini olucindezelayo (amagesi), i-expander ingumshini ofanele.
I-Expander iwubuchwepheshe obuvuthiwe obunezinhlelo eziningi eziphumelelayo ezifana nokuqhekeka kwe-fluid catalytic (FCC), isiqandisi, amavalvu edolobha legesi yemvelo, ukuhlukaniswa komoya noma ukukhishwa kwe-exhaust. Empeleni, noma yikuphi ukusakaza kwegesi okunengcindezi encishisiwe kungasetshenziswa ukushayela i-expander, kodwa "umphumela wamandla ulingana ngokuqondile nesilinganiso sokucindezela, izinga lokushisa kanye nezinga lokugeleza kwegesi" [2], kanye nokwenzeka kwezobuchwepheshe nezomnotho. Ukwenziwa Kwe-Expander: Inqubo incike kulezi nezinye izici, njengezintengo zamandla endawo kanye nokuba khona komkhiqizi wezisetshenziswa ezifanele.
Nakuba i-turboexpander (isebenza ngokufana ne-turbine) iwuhlobo lwe-expander eyaziwa kakhulu (Umfanekiso 1), kunezinye izinhlobo ezifanele izimo zenqubo ezahlukene. Lesi sihloko sethula izinhlobo eziyinhloko zezandisi nezingxenye zazo futhi sifingqa ukuthi abaphathi bemisebenzi, abaxhumanisi noma abacwaningi mabhuku bamandla ezigabeni ezihlukahlukene ze-CPI bangakwazi kanjani ukuhlola izinzuzo ezingaba khona zezomnotho nezemvelo zokufaka isinwebi.
Kunezinhlobo eziningi ezahlukene zamabhendi okumelana ahluka kakhulu ngejometri kanye nomsebenzi. Izinhlobo eziyinhloko zikhonjiswe kuMfanekiso 2, futhi uhlobo ngalunye luchazwe kafushane ngezansi. Ukuze uthole ulwazi olwengeziwe, kanye namagrafu aqhathanisa isimo sokusebenza sohlobo ngalunye ngokusekelwe kumadayamitha athile nesivinini esithile, bheka Usizo. 3.
I-Piston turboexpander. I-Piston ne-rotary piston turboexpanders zisebenza njengenjini evuthayo yangaphakathi ezungezayo, emunca igesi enomfutho ophezulu futhi iguqule amandla ayo agciniwe abe amandla ajikelezayo ngokusebenzisa i-crankshaft.
Hudula i-turbo expander. Isandisi se-turbine yamabhuleki siqukethe igumbi lokugeleza eligxilile elinamaphiko ebhakede anamathiselwe kumngcele we-elementi ejikelezayo. Zakhiwe ngendlela efanayo namasondo amanzi, kodwa ingxenye ephambanayo yamakamelo agxilile iyanda ukusuka ekungeneni kuya kokuphumayo, okuvumela igesi ukuba yande.
I-radial turboexpander. I-Radial flow turboexpanders ine-axial inlet kanye ne-radial outlet, evumela igesi ukuthi inwebe ngokukhazimulayo nge-impeller ye-turbine. Ngokufanayo, ama-axial flow turbines andisa igesi ngesondo le-turbine, kodwa isiqondiso sokugeleza sihlala sihambisana ne-eksisi yokuzungezisa.
Lesi sihloko sigxile kuma-radial kanye ne-axial turboexpanders, sixoxa ngezinhlobo zabo ezincanyana, izakhi, kanye nezomnotho.
I-turboexpander ikhipha amandla emfudlaneni yegesi enengcindezi ephezulu futhi iwaguqule abe umthwalo wedrayivu. Ngokuvamile umthwalo uyi-compressor noma i-generator exhunywe ku-shaft. I-turboexpander ene-compressor compressor fluid kwezinye izingxenye zenqubo yokugeleza edinga uketshezi olucindezelwe, ngaleyo ndlela ikhulise ukusebenza kahle okuphelele kwesitshalo ngokusebenzisa amandla amoshayo ngenye indlela. I-turboexpander enomthwalo wejeneretha iguqula amandla abe ugesi, angasetshenziswa kwezinye izinqubo zezitshalo noma abuyiselwe kugridi yendawo ukuze athengiswe.
Amajeneretha e-Turboexpander angahlonywa nge-shaft yokushayela eqondile ukusuka esondo lika-turbine ukuya ku-generator, noma ngebhokisi le-gearbox elehlisa ngempumelelo isivinini sokufaka ukusuka esondo lika-turbine kuya ku-generator ngokusebenzisa isilinganiso segiya. I-Direct drive turboexpanders inikezela ngezinzuzo ekusebenzeni kahle, izindleko zezinyawo nezokulungisa. Ama-Gearbox turboexpander asindayo futhi adinga unyawo olukhudlwana, okokusebenza kwezinsiza zokuthambisa, nokunakekelwa okuvamile.
I-Flow-through turboexpanders ingenziwa ngendlela yama-radial noma ama-axial turbines. Izandisi zokugeleza kwe-radial ziqukethe i-axial inlet kanye ne-radial outlet kangangokuthi ukugeleza kwegesi kuphuma ku-turbine nge-radially kusuka ku-eksisi yokuzungezisa. Ama-axial turbines avumela igesi ukuthi igeleze ngokuhambisana ne-axis of rotation. Ama-axial flow turbines akhipha amandla ekugelezeni kwegesi ngokusebenzisa i-vanes ye-inlet guide kuya esondweni le-expander, nendawo ephambanayo yegumbi lokunweba ikhula kancane kancane ukuze kugcinwe isivinini esingaguquki.
Ijeneretha ye-turboexpander iqukethe izingxenye ezintathu eziyinhloko: isondo le-turbine, ama-bearings akhethekile kanye nejeneretha.
Isondo le-turbine. Amasondo e-turbine ngokuvamile aklanyelwe ngokukhethekile ukuthuthukisa ukusebenza kahle kwe-aerodynamic. Izinto eziguquguqukayo zohlelo lokusebenza ezithinta ukwakheka kwamasondo e-turbine zihlanganisa ingcindezi ye-inlet/outlet, izinga lokushisa le-inlet/outlet, ukugeleza kwevolumu, nezakhiwo zoketshezi. Uma isilinganiso sokuminyanisa siphezulu kakhulu ukuthi singancishiswa esigabeni esisodwa, i-turboexpander enamasondo e-turbine amaningi iyadingeka. Womabili amasondo e-radial kanye ne-axial turbine angaklanywa njengezigaba eziningi, kodwa amasondo e-axial turbine anobude obufushane kakhulu be-axial ngakho-ke ahlangene kakhulu. Ama-multistage radial flow turbines adinga igesi ukuthi igeleze isuka ku-axial iye ku-radial futhi ibuyele ku-axial, okudala ukulahlekelwa okuphezulu kwe-friction kunama-axial flow turbines.
ama-bearings. Idizayini yokuthwala ibalulekile ekusebenzeni kahle kwe-turboexpander. Ukuthwala izinhlobo ezihlobene nemiklamo ye-turboexpander ziyahlukahluka kakhulu futhi zingabandakanya amabheringi kawoyela, amabheringi efilimu ewuketshezi, amabhola endabuko, namabheringi kazibuthe. Indlela ngayinye inezinzuzo zayo kanye nokubi, njengoba kuboniswe kuThebula 1.
Abakhiqizi abaningi be-turboexpander bakhetha ama-magnetic bearings "njengokukhetha kwabo" ngenxa yezinzuzo zabo eziyingqayizivele. Amabheringi kazibuthe aqinisekisa ukusebenza okungangqubuzani kwezingxenye eziguqukayo ze-turboexpander, ehlisa kakhulu izindleko zokusebenza nezokulungisa impilo yonke yomshini. Futhi zenzelwe ukumelana nemithwalo eminingi ye-axial kanye ne-radial kanye nezimo zokucindezeleka ngokweqile. Izindleko zabo zokuqala eziphakeme zikhokhiswa izindleko eziphansi kakhulu zomjikelezo wempilo.
amandla. Ijeneretha ithatha amandla ajikelezayo eturbine bese iwaguqulela amandla kagesi awusizo kusetshenziswa ijeneretha kagesi (okungaba ijeneretha yokungenisa noma ijeneretha kazibuthe unomphela). Amajeneretha okungenisa anesivinini esilinganiselwe esiphansi, ngakho-ke ukusetshenziswa kwe-turbine enesivinini esikhulu kudinga ibhokisi legiya, kodwa angaklanywa ukuze afane nefrikhwensi yegridi, kuqedwe isidingo se-variable frequency drive (VFD) yokuhlinzeka ugesi okhiqizwayo. Amajeneretha kazibuthe ahlala njalo, ngakolunye uhlangothi, angaxhunywa ku-shaft ngqo ku-turbine futhi adlulisele amandla kugridi ngedrayivu eguquguqukayo. Ijeneretha yakhelwe ukuletha amandla aphezulu ngokusekelwe kumandla we-shaft atholakala ohlelweni.
Izimpawu. Uphawu luphinde lube yingxenye ebalulekile lapho uklama uhlelo lwe-turboexpander. Ukuze kugcinwe ukusebenza kahle okuphezulu futhi kuhlangatshezwane namazinga emvelo, izinhlelo kufanele zivaliwe ukuze kuvinjelwe ukuvuza okungenzeka kwenqubo yegesi. Ama-Turboexpanders angafakwa ngezimpawu eziguquguqukayo noma ezimile. Ama-Dynamic seals, njenge-labyrinth seal kanye ne-gas seal eyomile, ahlinzeka ngophawu ezizungeze i-shaft ezungezayo, ngokuvamile phakathi kwesondo le-turbine, ama-bheringi kanye nawo wonke umshini lapho i-generator itholakala khona. Izigxivizo ezinamandla ziyaguga ngokuhamba kwesikhathi futhi zidinga ukunakekelwa njalo nokuhlolwa ukuze kuqinisekiswe ukuthi zisebenza kahle. Uma zonke izingxenye ze-turboexpander ziqukethwe endlini eyodwa, izimpawu ezimile zingasetshenziswa ukuvikela noma yimiphi imikhondo ephuma endlini, okuhlanganisa nejeneretha, amadrayivu anozibuthe, noma izinzwa. Lezi zimpawu ezingangeni moya zinikeza isivikelo saphakade ekuvuzeni kwegesi futhi azidingi ukulungiswa noma ukulungiswa.
Ngokombono wenqubo, imfuneko eyinhloko yokufaka i-expander iwukuba unikeze igesi ecindezelwayo ephezulu (engafinyeleli) ohlelweni lokucindezela okuphansi nokugeleza okwanele, ukwehla kwengcindezi kanye nokusetshenziswa ukuze kugcinwe ukusebenza okuvamile kwemishini. Amapharamitha okusebenza agcinwa ezingeni eliphephile nelisebenzayo.
Ngokuphathelene nomsebenzi wokunciphisa ingcindezi, i-expander ingasetshenziswa esikhundleni se-valve ye-Joule-Thomson (JT), eyaziwa nangokuthi i-throttle valve. Njengoba i-valve ye-JT ihamba ngendlela ye-isentropic futhi isinweshi sihamba ngendlela ecishe ibe yi-isentropic, lesi sakamuva sinciphisa i-enthalpy yegesi futhi siguqule umehluko we-enthalpy ube amandla e-shaft, ngaleyo ndlela sikhiqize izinga lokushisa eliphansi le-outlet kune-valve ye-JT. Lokhu kuyasiza ezinkambisweni ze-cryogenic lapho umgomo uwukunciphisa izinga lokushisa legesi.
Uma kunomkhawulo ophansi ekushiseni kwegesi ephumayo (isibonelo, esiteshini sokucindezelwa lapho izinga lokushisa legesi kufanele ligcinwe ngaphezu kweqhwa, i-hydration, noma izinga lokushisa elincane lokuklama impahla), okungenani kufanele kwengezwe i-heater eyodwa. lawula izinga lokushisa legesi. Lapho i-preheater itholakala phezulu komfula, amanye amandla avela kugesi ophakelayo nawo atholakala kusinwebeka, ngaleyo ndlela andise ukuphuma kwawo kwamandla. Kwezinye izimo lapho kudingeka khona ukulawula izinga lokushisa kwe-outlet, i-reheater yesibili ingafakwa ngemva kwe-expander ukuze inikeze ukulawula okusheshayo.
Emfanekisweni 3 ubonisa umdwebo owenziwe lula womdwebo ojwayelekile wokugeleza wejeneretha enwebekayo ene-preheater esetshenziswa esikhundleni se-valve ye-JT.
Kokunye ukucushwa kwenqubo, amandla atholwe ku-expander angadluliselwa ngqo ku-compressor. Le mishini, ngezinye izikhathi ebizwa ngokuthi “ama-commander”, ivamise ukuba nezigaba zokunwetshwa nokucindezelwa okuxhunywe umphini owodwa noma ngaphezulu, okungase kuhlanganise no-gearbox wokulawula umehluko wejubane phakathi kwalezi zigaba ezimbili. Ingase futhi ihlanganise injini eyengeziwe ukuze inikeze amandla engeziwe esiteji sokucindezela.
Ngezansi kukhona ezinye zezingxenye ezibaluleke kakhulu eziqinisekisa ukusebenza kahle nokuzinza kwesistimu.
I-valve ye-bypass noma i-valve yokunciphisa ingcindezi. Ivalvu ye-bypass ivumela ukusebenza ukuthi kuqhubeke lapho i-turboexpander ingasebenzi (isibonelo, ukulungisa noma isimo esiphuthumayo), kuyilapho i-valve yokunciphisa ingcindezi isetshenziselwa ukusebenza okuqhubekayo ukuze kuhlinzekwe igesi eyeqile lapho ukugeleza okuphelele kudlula umthamo womklamo wesinwebi.
I-valve yokuvala i-Emergency (ESD). Amavalvu e-ESD asetshenziselwa ukuvimba ukugeleza kwegesi ku-expander esimweni esiphuthumayo ukugwema ukulimala komshini.
Izinsimbi nezilawuli. Okuguquguqukayo okubalulekile okufanele kuqashwe kuhlanganisa ingcindezi yokungena nokuphumayo, izinga lokugeleza, isivinini sokujikeleza, nokuphuma kwamandla.
Ukushayela ngesivinini eseqile. Idivayisi inqamula ukugeleza ku-turbine, okwenza i-turbine rotor ukuthi ihambe kancane, ngaleyo ndlela ivikele okokusebenza esivinini esidlulele ngenxa yezimo zenqubo ezingalindelekile ezingase zilimaze okokusebenza.
I-Pressure Safety Valve (PSV). Ama-PSV avame ukufakwa ngemva kwe-turboexpander ukuvikela amapayipi kanye nemishini yokucindezela okuphansi. I-PSV kufanele yakhelwe ukumelana nezimo ezibucayi kakhulu, ngokuvamile ezihlanganisa ukwehluleka kwevalvu yokudlula ukuvula. Uma isandisi sengezwa esiteshini esikhona sokunciphisa ingcindezi, ithimba lokuklama inqubo kufanele linqume ukuthi i-PSV ekhona inikeza ukuvikeleka okwanele yini.
I-heater. Izifudumezi zinxephezela ukwehla kwezinga lokushisa okubangelwa igesi edlula ku-turbine, ngakho-ke igesi kufanele ifudumale. Umsebenzi wayo oyinhloko ukukhulisa izinga lokushisa lokugeleza kwegesi elikhuphukayo ukuze kugcinwe izinga lokushisa legesi lishiya i-expander ngaphezu kwenani elincane. Enye inzuzo yokukhuphula izinga lokushisa ukukhulisa amandla okukhipha amandla kanye nokuvimbela ukugqwala, ukufiphala, noma ama-hydrates angaphazamisa kabi imibhobho yemishini. Kumasistimu aqukethe izishintshisi zokushisa (njengoba kuboniswe kuMfanekiso 3), izinga lokushisa legesi ngokuvamile lilawulwa ngokulawula ukugeleza koketshezi olushisayo ku-preheater. Kweminye imiklamo, i-heater yomlilo noma i-heater kagesi ingasetshenziswa esikhundleni sesishintshi sokushisa. Izifudumezi zingase zikhona kakade esiteshini esikhona se-valve ye-JT, futhi ukwengeza i-expander kungase kungadingi ukufaka izifudumezi ezengeziwe, kodwa kunalokho kwandise ukugeleza koketshezi olushisayo.
Amasistimu wokugcoba uwoyela negesi yophawu. Njengoba kushiwo ngenhla, ama-expander angasebenzisa imiklamo ehlukene yophawu, engadinga ama-lubricant namagesi okuvala. Lapho kufanele khona, amafutha okugcoba kufanele agcine izinga eliphezulu kanye nokuhlanzeka lapho ethintana namagesi enqubo, futhi izinga le-viscosity kawoyela kufanele lihlale ngaphakathi kwebanga lokusebenza elidingekayo lamabheringi agcotshiwe. Amasistimu egesi evaliwe ngokuvamile afakwe idivayisi yokugcoba uwoyela ukuvimbela uwoyela osuka ebhokisini elithwalayo ukuthi ungangeni ebhokisini lokunweba. Ngokusetshenziswa okukhethekile kwezihlanganisi ezisetshenziswa embonini ye-hydrocarbon, uwoyela we-lube negesi yophawu ngokuvamile aklanyelwe ukucaciswa kwe-API 617 [5] Ingxenye 4.
I-Vaable frequency drive (VFD). Uma ijeneretha ifakwa, i-VFD ivamise ukuvulwa ukuze kulungiswe isignali yamanje (AC) eshintshayo ukuze ifane nemvamisa yokusetshenziswa. Imvamisa, imiklamo esuselwe kumadrayivu okuguquguqukayo asebenza kahle kakhulu kunemiklamo esebenzisa amabhokisi egiya noma ezinye izakhi zemishini. Amasistimu asekelwe ku-VFD angakwazi futhi ukwamukela uhla olubanzi lwezinguquko zenqubo ezingaholela ekushintsheni kwesivinini se-expander shaft.
Ukudluliswa. Eminye imiklamo ye-expander isebenzisa i-gearbox ukunciphisa isivinini se-expander sibe isivinini esilinganiselwe se-generator. Izindleko zokusebenzisa i-gearbox ziphansi ukusebenza kahle kukonke ngakho-ke amandla aphansi aphumayo.
Lapho elungiselela isicelo sekhotheshini (RFQ) sesandisi, unjiniyela wenqubo kufanele aqale anqume izimo zokusebenza, okuhlanganisa ulwazi olulandelayo:
Onjiniyela bemishini bavame ukuqedela ukucaciswa kwejeneretha ye-expander kanye nokucaciswa besebenzisa idatha evela kweminye imikhakha yobunjiniyela. Lokhu okokufaka kungase kuhlanganise okulandelayo:
Imininingwane kufanele futhi ifake uhlu lwamadokhumenti nemidwebo ehlinzekwe umenzi njengengxenye yenqubo yethenda kanye nobubanzi bokuhlinzeka, kanye nezinqubo zokuhlola ezisebenzayo njengoba kudingwa iphrojekthi.
Ulwazi lobuchwepheshe olunikezwa umenzi njengengxenye yenqubo yethenda kufanele ngokuvamile luhlanganise izici ezilandelayo:
Uma noma iyiphi ingxenye yesiphakamiso ihluka kulokho okucacisiwe kwasekuqaleni, umenzi kufanele futhi anikeze uhlu lokuchezuka kanye nezizathu zokuchezuka.
Uma isiphakamiso sesamukelwe, ithimba lokuthuthukisa iphrojekthi kufanele libuyekeze isicelo sokuthotshelwa komthetho futhi linqume ukuthi ukuhluka kuyafaneleka yini ngokobuchwepheshe.
Okunye okucatshangelwayo kwezobuchwepheshe okufanele kucatshangelwe lapho kuhlolwa iziphakamiso kuhlanganisa:
Okokugcina, ukuhlaziya komnotho kufanele kwenziwe. Ngenxa yokuthi izinketho ezihlukene zingase ziphumele ezindlekweni ezihlukene zokuqala, kunconyelwa ukuthi kuhlaziywe ukugeleza kwemali noma umjikelezo wokuphila ukuze kuqhathaniswe umnotho wesikhathi eside wephrojekthi kanye nembuyiselo ekutshalweni kwezimali. Isibonelo, ukutshalwa kwezimali kwasekuqaleni okuphezulu kungase kuncishiswe ngokuhamba kwesikhathi ngenxa yokwanda kokukhiqiza noma izidingo zokunakekela ezincishisiwe. Bheka "Izithenjwa" ukuze uthole imiyalelo ngalolu hlobo lokuhlaziya. 4.
Zonke izinhlelo zokusebenza zokwenza i-turboexpander-generator zidinga isamba sokuqala sokubala samandla esingaba khona ukuze kutholwe inani eliphelele lamandla atholakalayo angatholwa ohlelweni oluthile. Kujeneretha ye-turboexpander, amandla anamandla abalwa njengenqubo ye-isentropic (i-entropy eqhubekayo). Lesi isimo esifanelekile se-thermodynamic sokucabangela inqubo ye-adiabatic ehlehliswayo ngaphandle kokungqubuzana, kodwa inqubo efanele yokulinganisa amandla angempela wamandla.
I-Isentropic potential energy (IPP) ibalwa ngokuphindaphinda umehluko othile we-enthalpy endaweni yokungena nokuphuma kwe-turboexpander futhi kuphindaphindeka umphumela ngesilinganiso sokugeleza okukhulu. La mandla angaba khona azovezwa njengenani le-isentropic (Isibalo (1)):
IPP = ( hinlet – h(i,e)) × ṁ x ŋ (1)
lapho u-h(i,e) kuyi-enthalpy ethile kucatshangelwa izinga lokushisa le-isentropic outlet kanye ṁ izinga lokugeleza okukhulu.
Nakuba amandla angaba khona e-isentropic angasetshenziswa ukulinganisa amandla angaba khona, wonke amasistimu angempela ahlanganisa ukungqubuzana, ukushisa, nokunye ukulahlekelwa kwamandla ahambisanayo. Ngakho-ke, lapho kubalwa amandla angempela wamandla, idatha yokokufaka eyengeziwe elandelayo kufanele inakwe:
Ezinhlelweni eziningi ze-turboexpander, izinga lokushisa likhawulelwe kokuncane ukuze kuvinjelwe izinkinga ezingafuneki njengokuqandisa kwamapayipi okukhulunywe ngakho ngaphambili. Lapho kugeleza khona igesi yemvelo, ama-hydrates ahlala ekhona, okusho ukuthi ipayipi elingezansi komfula we-turboexpander noma i-throttle valve lizoba yiqhwa ngaphakathi nangaphandle uma izinga lokushisa lehla ngaphansi kuka-0°C. Ukwakheka kweqhwa kungaholela ekuvinjweni kokugeleza futhi ekugcineni kuvale uhlelo ukuze luncibilike. Ngakho, izinga lokushisa le-outlet "elifiselekayo" lisetshenziselwa ukubala isimo samandla esingaba namaqiniso kakhulu. Nokho, kumagesi afana ne-hydrogen, izinga lokushisa liphansi kakhulu ngoba i-hydrogen ayishintshi isuka kugesi iye oketshezini kuze kube yilapho ifinyelela izinga lokushisa le-cryogenic (-253°C). Sebenzisa lokhu kushisa okufunayo ukuze ubale i-enthalpy ethile.
Ukusebenza kahle kohlelo lwe-turboexpander kumele kucatshangelwe. Ngokuya ngobuchwepheshe obusetshenzisiwe, ukusebenza kahle kwesistimu kungahluka kakhulu. Isibonelo, i-turboexpander esebenzisa igiya lokunciphisa ukudlulisa amandla ajikelezayo ukusuka ku-turbine kuya kujeneretha izothola ukulahlekelwa okukhulu kokungqubuzana kunesistimu esebenzisa ukushayela okuqondile ukusuka ku-turbine kuya kujeneretha. Ukusebenza kahle okuphelele kwesistimu ye-turboexpander kuvezwa njengephesenti futhi kuyabhekwa lapho kuhlolwa amandla wangempela we-turboexpander. Amandla wangempela wamandla (PP) abalwa kanje:
PP = (i-hinlet – hexit) × ṁ x ṅ (2)
Ake sibheke ukusetshenziswa kwengcindezi yegesi yemvelo. I-ABC isebenza futhi inakekele isiteshi sokunciphisa ingcindezi esithutha igesi yemvelo isuka epayipini elikhulu bese iyisabalalisa komasipala bendawo. Kulesi siteshi, ingcindezi yokungena kwegesi ingamabha angama-40 futhi ingcindezi yokuphuma iyibha engu-8. Izinga lokushisa legesi elifakwe kuqala liba ngu-35°C, elishisa igesi kusengaphambili ukuze livimbele ukubanda kwepayipi. Ngakho-ke, izinga lokushisa legesi eliphuma ngaphandle kufanele lilawulwe ukuze lingehli ngaphansi kuka-0°C. Kulesi sibonelo sizosebenzisa u-5°C njengezinga lokushisa elincane lokuphuma kwesitolo ukuze sandise isici sokuphepha. Izinga lokugeleza kwegesi yevolumu evamile ngu-50,000 Nm3/h. Ukuze ubale amandla anamandla, sizothatha ngokuthi yonke igesi igeleza ku-turbo expander futhi sibale umkhawulo wamandla okukhiphayo. Linganisela amandla aphelele okukhipha amandla usebenzisa lesi sibalo esilandelayo:
