LNG vs CNG: Chitsogozo Chokwanira Chosankha Mafuta a Gasi

Kumvetsetsa kusiyana, kugwiritsa ntchito, ndi tsogolo la LNG ndi CNG mumakampani opanga mphamvu

Chabwino n'chiti: LNG kapena CNG?

"Zabwino" zimatengera pulogalamu yomwe ikugwiritsidwa ntchito. LNG (Liquefied Natural Gas), yomwe imakhala yamadzi pa -162 ° C, ndi mphamvu yamphamvu kwambiri, yomwe imapangitsa kuti ikhale yabwino pamagalimoto apamtunda wautali, zombo, ndi masitima apamtunda. zomwe zimafunika kukhala ndi mtunda wautali kwambiri. Kuyenda mtunda waufupi monga ma taxi, mabasi, ndi magalimoto ang'onoang'ono ndi abwino kwambiri pa gasi woponderezedwa wachilengedwe (CNG), omwe amatha kusungidwa ngati mpweya wopanikizika kwambiri ndipo amakhala ndi mphamvu yocheperako. Chisankhocho chimadalira kukwaniritsa malire oyenera pakati pa kupezeka kwa zomangamanga ndi zosowa zosiyanasiyana.

Ndi magalimoto ati omwe amatha kuyenda pa CNG?

Mafuta amtunduwu amatha kugwiritsidwa ntchito m'magalimoto omwe adapangidwa kapena kusinthidwa kuti aziyenda pa gasi wachilengedwe woponderezedwa (CNG). Zomwe zimagwiritsidwa ntchito nthawi zambiri pa CNG zimaphatikizapo zombo zapamzinda, ma taxi, magalimoto ochotsa zinyalala, ndi zoyendera za anthu onse mumzinda (mabasi). Magalimoto a CNG opangidwa ndi fakitale amaperekedwanso pamagalimoto ambiri okwera, monga mitundu ina ya Honda Civic kapena Toyota Camry. Kuphatikiza apo, zida zosinthira zitha kugwiritsidwa ntchito kusinthira magalimoto ambiri okhala ndi injini zamafuta kuti aziyendetsa mafuta onse (mafuta / CNG), zomwe zimapereka kusinthasintha komanso kupulumutsa pamitengo.

Kodi LNG ingagwiritsidwe ntchito pamagalimoto?

Ngakhale kuti n'zotheka m'malingaliro, ndizosazolowereka komanso zosatheka kwa magalimoto wamba. Kuti asunge mawonekedwe amadzimadzi omwe -162 ° C, LNG imafunikira matanki ovuta, okwera mtengo osungira cryogenic. Machitidwewa ndi aakulu, okwera mtengo, ndipo si oyenera malo ang'onoang'ono oyenda magalimoto ang'onoang'ono. Masiku ano, magalimoto amphamvu, oyenda mtunda wautali ndi magalimoto ena akulu akulu okhala ndi malo osungira akasinja akulu komanso kuthekera kopeza zabwino kuchokera kumitundu yayitali ya LNG ndi pafupifupi magalimoto okhawo omwe amawagwiritsa ntchito.

Ndi kuipa kotani kwa CNG ngati mafuta?

Zoyipa zazikulu za CNG ndi kuchuluka kwake koyendetsa poyerekeza ndi dizilo kapena mafuta amafuta komanso njira yake yochepa yopangira mafuta, makamaka m'maiko omwe akutukuka kumene. Chifukwa matanki a CNG ndi aakulu komanso olemera, nthawi zambiri amatenga malo ambiri onyamula katundu, makamaka m'magalimoto okwera. Kuphatikiza apo, magalimoto nthawi zambiri amawononga ndalama zambiri kugula kapena kusintha poyamba. Kuphatikiza apo, nthawi yothira mafuta ndi yayitali kuposa mafuta amadzimadzi, ndipo magwiridwe antchito atha kukhala otsika pang'ono poyerekeza ndi injini zofananira zomwe zimayendetsedwa ndi petulo.

Kodi pali malo angati odzaza CNG ku Nigeria?

Dongosolo la Nigeria la malo opangira mafuta a CNG adakalipobe kuyambira koyambirira kwa 2024. Malipoti aposachedwa ochokera kumakampaniwa akuwonetsa kuti pali masiteshoni angapo amtundu wa CNG omwe akugwira ntchito ndikuwonetsa zomwe zimachokera ku 10 mpaka 20 masiteshoni. Ambiri mwa awa ali m'mizinda ikuluikulu monga Lagos ndi Abuja. Komabe, m’zaka zikubwerazi, chiŵerengerochi chikhoza kukwera mofulumira chifukwa cha “Pulojekiti Yotukula Gasi” ya boma, yomwe imathandizira gasi wachilengedwe monga gwero lotsika mtengo komanso losunga bwino mphamvu zoyendetsera magetsi.

Kodi thanki ya CNG imakhala yotani?

Matanki a CNG ali ndi nthawi yovuta yogwiritsidwa ntchito, yomwe nthawi zambiri imawonetsedwa ndi tsiku logwiritsidwa ntchito kuyambira pomwe amapangidwa m'malo mwazaka zambiri. Miyezo yambiri yapadziko lonse lapansi komanso yapadziko lonse lapansi imafuna kuti akasinja a CNG, kaya opangidwa ndi zinthu zopangidwa ndi chitsulo kapena chitsulo, akhale ndi moyo wogwiritsa ntchito zaka 15-20. ziribe kanthu za chikhalidwe chodziwikiratu, thanki iyenera kukonzedwa pakapita kanthawi kuti zitsimikizire kuti zikuchitika chitetezo. Monga gawo la mapulani okonzekera nthawi zonse, akasinja amafunikanso kuyang'anitsitsa khalidwe lawo poyang'ana maso ndi kuyesa kupanikizika nthawi zonse.

Chabwino n'chiti, LPG kapena CNG?

Onse a CNG kapena LPG (mafuta amafuta amafuta) ndi njira zina zamafuta okhala ndi mawonekedwe apadera. Poyerekeza ndi LPG (propane/butane), yomwe imakhala yolemera kwambiri kuposa mpweya ndipo imatha kumanga, CNG, yomwe makamaka ndi methane, imakhala yochepa kuposa mpweya ndipo imasweka mwamsanga ngati itasweka. Chifukwa CNG imayaka bwino, imasiya madipoziti ochepa m'magawo a injini. Komano, LPG ili ndi njira yokhazikika komanso yokulirakulira padziko lonse lapansi, mphamvu zambiri, komanso njira yabwinoko. Chisankhochi nthawi zambiri chimakhudzidwa ndi mtengo wamafuta m'dera lino, kuchuluka kwa magalimoto, ndi njira zothandizira zomwe zilipo.

Kodi pali kusiyana kotani pakati pa LNG ndi CNG?

Mkhalidwe wawo wakuthupi ndi njira zosungiramo zomwe zimasiyana kwambiri. Mpweya wachilengedwe woponderezedwa, kapena CNG, umakhalabe mumtundu wa gasi pazovuta kwambiri (nthawi zambiri 200-250 bar). LNG, kapena gasi wachilengedwe wopangidwa ndi liquefied, ndi mpweya womwe umapangidwa potsitsa mpweya wachilengedwe kufika -162 ° C, womwe umausintha kukhala madzi ndikuchepetsa kuchuluka kwake pafupifupi nthawi 600. Chifukwa cha izi, LNG ili ndi mphamvu zambiri kuposa CNG, zomwe zimapangitsa kuti zikhale zoyenera kuyenda mtunda wautali komwe kupirira ndikofunikira. Komabe, pamafunika zida zosungiramo za cryogenic zodula komanso zotsika mtengo.

Kodi thanki ya LNG ndi chiyani?

Chipangizo chosungirako cha cryogenic kwambiri ndi thanki ya LNG. Cholinga chachikulu ndikuchepetsa mpweya wotuluka m'madzi (BOG) posunga LNG m'malo ake amadzimadzi pamtunda wotsika kwambiri pafupifupi -162 ° C. Matankiwa ali ndi mapangidwe ovuta a makoma awiri okhala ndi kutsekemera kwapamwamba pakati pa makoma ndi vacuum mkati. LNG imatha kusungidwa ndikusuntha mtunda wautali pogwiritsa ntchito magalimoto, zombo, ndi malo osungira osawonongeka pang'ono chifukwa cha kapangidwe kameneka.

Kodi CNG station ndi chiyani?

Malo apadera omwe amapereka mafuta agalimoto zoyendetsedwa ndi CNG amatchedwa CNG station. Gasi wachilengedwe nthawi zambiri amatengedwa kupita komweko ndi mphamvu yotsika ndi njira zoyendera zoyandikana nawo. Kutsatira izi, gasi uyu amatsukidwa, kuziziritsidwa, ndikuunikizidwa m'magawo angapo pogwiritsa ntchito ma compressor amphamvu kuti akwaniritse zovuta kwambiri (pakati pa 200 ndi 250 bar). Mapaipi osungira okhala ndi mathithi amagwiritsidwa ntchito kusunga mpweya wothamanga kwambiri. poyerekeza ndi kuwonjezera mafuta ndi mafuta, koma pogwiritsa ntchito mpweya wothamanga kwambiri, gasiyo amaperekedwa kuchokera ku mabanki osungiramo zinthuzi kulowa m'galimoto mkati mwa thanki ya CNG pogwiritsa ntchito makina apadera.

Kodi pali kusiyana kotani pakati pa LNG ndi gasi wamba?

Mafutawa nthawi zambiri amatchedwa "gasi wamba". Mafuta achilengedwe a methane, kapena LNG, ndi gasi wopanda vuto lomwe lasungidwa bwino lomwe limapangidwa kuchokera kumafuta oyeretsedwa, LNG imapanga zinthu zosavulaza (monga ma nitrogen oxides (NOx), ma sulfure oxides, ndi zinthu za carbon dioxide (CO2). Mosiyana ndi dongosolo la LNG lomwe likukulabe, mafuta amafuta amakhala ndi mphamvu zambiri pamlingo uliwonse ndipo amasangalala ndi maukonde otukuka kwambiri padziko lonse lapansi.

Pakusintha kukhala mphamvu zoyeretsa, LNG ndi CNG ndizothandizana m'malo mopikisana ndi zinthu. Kwa maulendo ataliatali, mayendedwe owopsa, momwe kuchuluka kwamphamvu kwa mphamvu zake kumapereka gawo lofunikira, LNG ndiye chisankho chabwino kwambiri. Kumbali ina, CNG ndi njira yabwino kwambiri komanso yosamalira zachilengedwe kwa mabizinesi ndi mizinda yokhala ndi magalimoto opepuka omwe amayenera kuyenda pang'ono. Mafuta onsewa adzakhala ofunikira pakuwongolera kusintha kwa mphamvu, kuchepetsa kutulutsa mpweya, ndikutsitsa mtengo wamafuta m'misika yomwe ikukula ngati Nigeria. Mitundu yeniyeni ya magalimoto, mitundu yoyendetsera ntchito, komanso kakulidwe ka ntchito zapaderalo ziyenera kuganiziridwa mosamala posankha pakati pawo.
