Tanka ea polokelo ea HT(Q)LNG - Tharollo ea polokelo ea boleng bo holimo ea LNG
Molemo oa sehlahisoa
Liquefied natural gas (LNG) e fetohile mohloli oa bohlokoa oa matla, haholo-holo ka lebaka la melemo ea eona ea tikoloho le ho feto-fetoha ha maemo. Ho nolofatsa polokelo le lipalangoang, ho ile ha etsoa litanka tsa polokelo tse khethehileng tse bitsoang HT(Q)LNG. Litanka tsena li na le litšobotsi tse ikhethang tse li etsang khetho ea pele bakeng sa polokelo e ngata ea LNG. Sehloohong sena, re tla hlahloba likarolo tsa mantlha tsa litanka tsa polokelo tsa HT(Q) LNG le melemo eo li e tlisang.
E 'ngoe ea likarolo tse ka sehloohong tsa litanka tsa polokelo tsa HT(Q)LNG ke bokhoni ba tsona bo phahameng ba ho kenya mocheso. Litanka tsena li etselitsoe ho fokotsa tahlehelo ea LNG ka lebaka la mouoane ka ho fana ka mouoane o sebetsang hantle. Sena se finyelloa ka ho kenyelletsa likarolo tse ngata tsa ho kenya letsoho, tse kang perlite kapa polyurethane foam, e leng ho fokotsang mocheso oa mocheso ka katleho. Ka hona, litanka li boloka LNG ka mocheso o tlase haholo, ho netefatsa botsitso le ho fokotsa tahlehelo ea matla.
Ntho e 'ngoe ea litanka tsa polokelo ea HT (Q) LNG ke bokhoni ba tsona ba ho mamella khatello e phahameng ea ka hare. Litanka tsena li entsoe ka thepa e matla, e kang tšepe e sa hloekang ea boemo bo phahameng kapa carbon steel, e khonang ho mamella likhatello tse phahameng tse hlahisoang ke LNG. Ho feta moo, li na le lisebelisoa tse tsoetseng pele tsa ho hlahloba le ho laola ho netefatsa hore litanka li sebetsa ka har'a sebaka se sireletsehileng sa khatello. Sena se tiisa polokeho le botshepehi ba tanka, ho thibela ho dutla kapa dikotsi tse ka bang teng.
Moralo oa litanka tsa polokelo ea HT(Q) LNG o boetse o ela hloko litlamorao tsa lintlha tse kantle, joalo ka liketsahalo tsa ho sisinyeha ha lefatše le maemo a leholimo a matla. Litanka li etselitsoe ho mamella litšisinyeho tsa lefatše le likoluoa tse ling tsa tlhaho, ho netefatsa hore LNG e lula e bolokehile le linakong tsa merusu. Ho phaella moo, litanka tsena li na le liphahlo tse sireletsang tse li sireletsang linthong tse senyang tse kang metsi a letsoai kapa mocheso o feteletseng, kahoo li eketsa nako e telele le ho phela nako e telele.
Ho feta moo, litanka tsa polokelo tsa HT(Q) LNG li etselitsoe ho fana ka tšebeliso e nepahetseng ea sebaka. Litanka tsena li tla ka boholo le litlhophiso tse fapaneng 'me li ka etsoa ho latela litlhoko tsa sebaka le polokelo. Moralo o mocha oa litanka tsena o li nolofalletsa ho boloka LNG e ngata sebakeng se senyenyane, ho sebelisa sebaka se lekanyelitsoeng hantle. Sena se molemo haholo bakeng sa liindasteri kapa lits'ebeletso tse nang le sebaka se lekanyelitsoeng empa li hloka boholo ba polokelo ea LNG.
Litanka tsa polokelo tsa HT(Q) LNG le tsona li na le likarolo tse ntle tsa polokeho. Ba na le lisebelisoa tse tsoetseng pele tsa ho thibela mollo ho kenyeletsa lisebelisoa tsa ho lemoha mollo le lisebelisoa tsa ho thibela mollo oa foam. Mehato ena ea tšireletso e tiisa ho thibela le ho tima ka potlako haeba mollo o hlaha, ho fokotsa kotsi ea ho phatloha kapa tšenyo e khōlō.
Ntle le litšobotsi tsena, litanka tsa polokelo tsa HT(Q) LNG li fana ka melemo e mengata ea bohlokoa. Taba ea pele, litanka tsena li ka boloka LNG ka mokhoa o ts'epahalang le ka mokhoa o bolokehileng ka nako e telele. Sena se bohlokoa bakeng sa limela tsa matla, lisebelisoa tsa indasteri kapa likepe, ho netefatsa phepelo e tsitsitseng ea LNG ntle le tšitiso. Ho feta moo, ho sebelisa litanka tsa polokelo tsa HT(Q) LNG ho fokotsa haholo khabone kaha LNG e le mafura a hloekileng ha a bapisoa le mafura a mang. Ka ho khothaletsa tšebeliso ea LNG, litanka tsena li kenya letsoho ho ts'oarellang tikoloho le ho thusa ho loants'a phetoho ea maemo a leholimo.
Ka kakaretso, litanka tsa polokelo tsa HT(Q) LNG li na le litšobotsi tsa mantlha tse li etsang khetho ea pele ea ho boloka LNG. Bokhoni ba bona bo phahameng ba ho kenya mocheso, bokhoni ba ho mamella likhatello tse phahameng, ho ikamahanya le maemo a ka ntle, tšebeliso e nepahetseng ea sebaka le likarolo tse ntlafetseng tsa tšireletso li etsa hore e be tharollo e loketseng bakeng sa liindasteri le lisebelisoa tse hlokang polokelo ea LNG e tšepahalang le e sireletsehileng. Ho feta moo, ts'ebeliso ea litanka tsa polokelo ea HT(Q) LNG e ka fokotsa tlhahiso ea khabone le ho kenya letsoho ntlafatsong e tsitsitseng ea tikoloho. Ha tlhoko ea LNG e ntse e hola, litanka tsena li tla bapala karolo ea bohlokoa ho fihlela litlhoko tsa lefats'e tsa matla ha li ntse li netefatsa polokeho le boikarabello ba tikoloho.
Lisebelisoa tsa Sehlahisoa
Liquefied Natural Gas (LNG) e se e tumme haholo joalo ka mokhoa o hloekileng le o sebetsang hantle ho feta libeso tsa setso. Ka matla a eona a phahameng le melemo ea tikoloho, LNG e se e tlatselitse haholo phetohong ea matla a lefats'e. Karolo e 'ngoe ea bohlokoa ea phepelo ea LNG ke litanka tsa polokelo tsa HT(QL)NG, tse bapalang karolo ea bohlokoa ho bolokeng le ho aba LNG.
Litanka tsa polokelo tsa HT(QL)NG li etselitsoe ho boloka LNG ka mocheso o tlase haholo, hangata ka tlase ho likhato tse 162 tsa Celsius. Litanka tsena li hahiloe ka lisebelisoa tse khethehileng le mekhoa ea ho kenya letsoho e khonang ho mamella maemo a batang haholo. Ho boloka LNG ka litanka tsena ho netefatsa hore thepa ea eona ea 'mele e bolokiloe, e etsa hore e tšoanelehe bakeng sa lipalangoang le tšebeliso e latelang.
Lisebelisoa tsa litanka tsa polokelo tsa HT(QL)NG li fapane ebile li atile. Litanka tsena li sebelisoa hangata indastering ea LNG ho boloka le ho aba LNG ho basebelisi ba fapaneng ba ho qetela. Li bohlokoa ho ts'ehetsa lifeme tsa motlakase tse fehloang ka khase ea tlhaho, lisebelisoa tsa ho futhumatsa matlo le khoebo, lits'ebetso tsa indasteri le lefapha la lipalangoang.
Molemo o mong oa bohlokoa oa litanka tsa polokelo tsa HT(QL)NG ke bokhoni ba tsona ba ho boloka khase e ngata ea tlhaho sebakeng se batlang se le nyane. Litanka tsena li hahiloe ka boholo bo fapaneng 'me li ka boloka LNG ho tloha ho li-cubic metres tse likete tse' maloa ho isa ho li-cubic metres tse likete tse 'maloa. Ho tenyetseha hona ho lumella tšebeliso e nepahetseng ea mobu le ho netefatsa phepelo e tsitsitseng ea LNG ho fihlela tlhoko.
Molemo o mong oa litanka tsa polokelo tsa HT(QL)NG ke litekanyetso tsa tsona tse phahameng tsa polokeho. Litanka tsena li etselitsoe le ho hahuoa ho mamella ho feto-fetoha ha mocheso o feteletseng, ts'ebetso ea litšisinyeho tsa lefatše, le lintlha tse ling tsa tikoloho. Li kenyelletsa likarolo tsa ts'ireletso tse tsoetseng pele joalo ka lits'oants'o tse habeli, li-valve tsa pholiso ea khatello, le lits'ebetso tse tsoetseng pele tsa ho bona ho lutla, ho netefatsa polokelo e bolokehileng le ho sebetsana le LNG.
Ho feta moo, litanka tsa polokelo tsa HT(QL)NG li etselitsoe ho tšoarella nako e telele. Lisebelisoa tse sebelisoang ha li hahoa ha li khone ho bola, li netefatsa botšepehi ba tanka le ho thibela ho lutla kapa ho senya. Ho tšoarella hona ho tiisa ho ba teng ha nako e telele le ho ts'epahala ha LNG e bolokiloeng.
Tsoelo-pele ea theknoloji ea tanka ea polokelo ea HT(QL)NG le eona e lebisitse ho nts'etsopele ea litharollo tse ncha le tse bolokang chelete e ngata. Tsena li kenyelletsa nts'etsopele ea lits'ebetso tsa ho lekola litanka tse fanang ka data ea nako ea nnete ka maemo a LNG, khatello le mocheso. Sena se lumella taolo e nepahetseng ea thepa le ho ntlafatsa phepelo eohle ea LNG.
Ho feta moo, litanka tsa polokelo tsa HT(QL)NG li kenya letsoho ho fokotsa ho tsoa ha likhase tse futhumatsang lefatše. Ka ho boloka LNG mochesong o tlaase haholo, litanka tsena li thibela ho tsoa mouoane ha eona le ho ntša methane, e leng khase e matla e futhumatsang lefatše. Sena se tiisa hore LNG e lula e le khetho ea mafura e hloekileng le e se nang tikoloho.
Qetellong, litanka tsa polokelo tsa HT(QL)NG ke likarolo tsa bohlokoa tsa phepelo ea LNG, tse thusang ho boloka le ho ajoa ha LNG lits'ebetsong tse fapaneng. Bokhoni ba bona ba ho boloka LNG e ngata, litekanyetso tse phahameng tsa ts'ireletso, ho tšoarella, le ts'ebeliso e ntle ea litšenyehelo li li etsa karolo ea bohlokoa ea meaho phetohong ea matla. Ka tlhoko e ntseng e hola ea lefats'e ea matla a hloekileng, bohlokoa ba litanka tsa polokelo tsa HT(QL)NG ho ts'ehetsa ho amoheloa ha LNG joalo ka mohloli oa mafura bo ke ke ba fetisoa.
