Chii chinonzi LNG Refueling Station?

Nekusimudzirwa zvishoma nezvishoma kwekubuda kwekabhoni yakaderera, nyika dzepasi rose dziri kutsvagawo manyuko ari nani emagetsi ekutsiva peturu muchikamu chezvekutakurwa. Chinhu chikuru cheliquefied natural gas (LNG) imethane, rinova gasi rechisikigo ratinoshandisa muupenyu hwedu hwezuva nezuva. Chaizvoizvo igasi. Pasi pekumanikidzwa kwakajairwa, kuitira kufambisa kufambisa uye kuchengetedza, gasi rechisikigo rinotonhodzwa kusvika paminus 162 degrees Celsius, richishanduka kubva kune gasi kuenda kumvura. Panguva ino, vhoriyamu yemvura yakasikwa gasi ingangoita 1/625 yevhoriyamu yegasi rechisikigo gasi rehukuru hwakafanana. Saka, chii chinonzi LNG yekuzadza chiteshi? Nhau idzi dzichaongorora musimboti wekushanda, hunhu hwekuzadza, uye basa rakakosha raanoita mune yazvino simba shanduko wave.

Chii chinonzi LNG refueling station?
Ichi chishandiso chakakosha chakagadzirirwa kuchengetedza uye kuwedzera mafuta LNG. Iyo inonyanya kupa LNG mafuta emarori ekutakura zvinhu kure, mabhazi, marori anorema kana ngarava. Yakasiyana neyakajairwa peturu uye zviteshi zvedhiziri, zviteshi izvi zvinonyungudutsa gasi rinotonhora zvakanyanya (-162 ℃) rechisikigo kuita mamiriro emvura, zvichiita kuti zvive nyore kuchengeta nekutakura.

Kuchengetedza: LNG inotakurwa kuburikidza nematangi e-cryogenic uye inochengetwa mumatangi ekutsvaira mukati meLNG yekuzadza zviteshi kuti ichengetedze yakaderera-tembiricha uye yemvura mamiriro emuviri.

Kuwedzera mafuta: Kana zvichidikanwa, shandisa pombi yeLNG kuendesa LNG kubva mutangi rekuchengetera kuenda kumushini wekuwedzera mafuta. Vashandi vekuwedzera mafuta vanobatanidza muromo wemuchina wekuzadza mafuta kune LNG yekuchengetera tangi yemotokari. Iyo yekuyerera mita mukati memushini wekuwedzera mafuta inotanga kuyera, uye LNG inotanga kuwedzerwa pasi pekumanikidzwa.

Ndezvipi zvikamu zvikuru zveLNG refueling station?
Yakadzika-tembiricha vacuum yekuchengetera tangi: Kaviri-layer insulated vacuum yekuchengetedza tangi, iyo inogona kuderedza kupisa kutamisa uye kuchengetedza tembiricha yekuchengetedza yeLNG.

Vaporizer: Chishandiso chinoshandura LNG yemvura kuita gasi CNG (re-gasification). Inonyanya kushandiswa kusangana nezvinodiwa zvekumanikidza panzvimbo yacho kana kudzora kudzvanywa kwematangi ekuchengetedza.

Dispenser: Yakashongedzerwa nehungwaru mushandisi interface, iyo yemukati yakashongedzerwa hose, inozadza nozzles, inoyerera mita uye zvimwe zvikamu zvakagadzirirwa yakaderera-tembiricha LNG.

Kudzora sisitimu: Ichave yakashongedzerwa nehungwaru, yakachengeteka uye yakabatanidzwa manejimendi sisitimu yekutarisa kudzvanywa, tembiricha yemidziyo yakasiyana-siyana panzvimbo, pamwe nechimiro cheLNG inventory.

Ndeupi mutsauko uripo pakati peLNG (liquefied natural gas) refueling zviteshi neCNG (compressed natural gas) zviteshi zvekuwedzera mafuta?
Liquefied Natural Gas (LNG): Inochengetwa mumhando yemvura patembiricha yeminus 162 degrees Celsius. Nekuda kwemamiriro ayo emvura, inotora nzvimbo shoma uye inogona kuzadzwa mumatangi emarori anorema uye marori anotakura zvinhu, achibvumira kureba kwekufamba. Hunhu hwakadaro hunoita kuti ive sarudzo yakasarudzika yemabhazi akareba uye marori anorema.

Yakadzvanywa Natural Gasi (CNG): Yakachengetwa mune yakakwirira-kumanikidza gasi fomu. Sezvo iri gasi, rinotora vhoriyamu yakakura uye rinowanzoda hombe pa-bhodhi gasi masilinda kana kudzokorodza kakawanda, zvichiita kuti ive yakakodzera kumota dzinofamba-famba senge mabhazi emuguta, mota dzakavanzika, nezvimwe.

Ndezvipi zvakanakira kushandisa liquefied natural gas (LNG)?
Kubva pamaonero ezvakatipoteredza, LNG ine hushamwari hwakatipoteredza kupfuura peturu. Kunyangwe mota dzeLNG dzine mutengo wekutanga wekutenga, zvinoda kudhura matangi ekuchengetedza cryogenic uye injini dzehunyanzvi, mutengo wemafuta wadzo wakadzikira. Kusiyana neizvi, mota dzepeturu, kunyangwe dzichikwanisika, dzine mitengo yakakwira yemafuta uye dzinokanganiswa nekushanduka kwemitengo yemafuta epasi rose. Kubva pamaonero ehupfumi, LNG ine mukana mukuru webudiriro.

Iyo liquefied natural gas refueling station yakachengeteka here?
Zvirokwazvo. Nyika yega yega ine dhizaini yakaenzana yezviteshi zvakanyungudutswa zvegasi, uye iwo akakodzera mayuniti ekuvaka anofanirwa kutevedzera zvakaomesesa zviyero zvekuvaka nekushanda. LNG pachayo haizoputika. Kunyangwe kana paine kudonha kweLNG, inokurumidza kuparara mumhepo uye haizounganidzi pasi uye kukonzera kuputika. Panguva imwecheteyo, chiteshi chemafuta chinozotorawo nzvimbo dzakawanda dzekuchengetedza, dzinogona kuona zvine hungwaru kana paine kuvuza kana kutadza kwemidziyo.
