Chii chinonzi LNG Refueling Station?

Nekusimudzirwa zvishoma nezvishoma kwemhepo ine kabhoni shoma, nyika pasi rose dziri kutsvagawo manyuko esimba ari nani ekutsiva peturu muchikamu chekufambisa. Chinhu chikuru chegasi rechisikigo rakanyungudutswa (LNG) imethane, inova gasi rechisikigo ratinoshandisa muhupenyu hwedu hwezuva nezuva. Chaizvoizvo igasi. Pasi pekumanikidzwa kwakajairika, kuitira kuti kutakurwa nekuchengetwa kuve nyore, gasi rechisikigo rinotonhodzwa kusvika padigiri Celsius 162, richichinja kubva pagasi kuenda parinenge riri mvura. Panguva ino, huwandu hwegasi rechisikigo rine mvura hunenge 1/625 yehuwandu hwegasi rechisikigo rine huremu hwakafanana. Saka, chii chinonzi LNG filling station? Nhau idzi dzichaongorora musimboti wekushanda, hunhu hwekuzadza, uye basa rakakosha rinoita mukushanduka kwesimba riripo.

Chii chinonzi LNG refilling station?
Ichi chishandiso chakakosha chakagadzirirwa kuchengetedza nekuzadza LNG. Chinonyanya kupa mafuta eLNG kumarori ekutakura zvinhu anofamba kure, mabhazi, marori anorema kana ngarava. Kusiyana nezviteshi zvepeturu nedhiziri zvemazuva ano, zviteshi izvi zvinonyungudutsa gasi rechisikigo rinotonhora zvikuru (-162℃) kuita mvura, zvichiita kuti zvive nyore kuchengeta nekutakura.

Kuchengetera: LNG inotakurwa kuburikidza nematangi e cryogenic uye inochengetwa mumatangi e vacuum mukati menzvimbo dzekuzadza LNG kuti irambe iine hunhu hwayo hwepanyama hwekupisa kwakaderera uye hwemvura.

Kuzadzazve mafuta: Kana zvichidikanwa, shandisa pombi yeLNG kutamisa LNG kubva mutangi rekuchengetera mafuta kuenda kumuchina wekuzadza mafuta. Vashandi vekuzadza mafuta vanobatanidza nozzle yemuchina wekuzadza mafuta netangi rekuchengetera mafuta remotokari. Chiyero chemvura chiri mukati memuchina wekuzadza mafuta chinotanga kuyera, uye LNG inotanga kuzadzwa mafuta pasi pekumanikidzwa.

Ndezvipi zvinhu zvikuru zvinoumba chiteshi chekudira mafuta cheLNG?
Tangi rekuchengetera vacuum rine tembiricha yakaderera: Tangi rekuchengetera vacuum rine mativi maviri rakaputirwa, rinogona kuderedza kutamiswa kwekupisa uye kuchengetedza tembiricha yekuchengetera yeLNG.

Vaporizer: Mudziyo unoshandura LNG yemvura kuita gaseous CNG (re-gasification). Unonyanya kushandiswa kusangana nezvinodiwa zvekumanikidzwa panzvimbo yacho kana kudzora kumanikidzwa kwematangi ekuchengetera.

Muchina wekupa mvura: Wakashongedzerwa neinterface yemushandisi yakangwara, mukati mawo mune mapombi, maburi ekuzadza, maflowmeter nezvimwe zvinhu zvakagadzirirwa LNG inodziya zvishoma.

Sisitimu yekudzora: Ichange iine sisitimu yekutarisira yakangwara, yakachengeteka uye yakabatana yekutarisa kumanikidzwa, tembiricha yemidziyo yakasiyana-siyana panzvimbo iyi, pamwe nemamiriro emidziyo yeLNG.

Ndeupi musiyano uripo pakati pezviteshi zvekuisa mafuta zveLNG (liquefied natural gas) nezviteshi zvekuisa mafuta zveCNG (compressed natural gas)?
Gasi Rechisikigo Rakanyungudika (LNG): Rinochengetwa muchimiro chemvura patembiricha iri pasi pe162 degrees Celsius. Nekuda kwemamiriro aro emvura, rinotora nzvimbo shoma uye rinogona kuzadzwa mumatangi emarori makuru nemarori ekutakura zvinhu, zvichibvumira kufamba daro refu. Hunhu hwakadaro hunoita kuti ive sarudzo inofarirwa nemabhazi marefu nemarori makuru.

Gasi Rechisikigo Rakamanikidzwa (CNG): Rinochengetwa muchimiro chegasi rine simba guru. Sezvo riri gasi, rinotora huwandu hwakawanda uye rinowanzoda masirinda egasi akakura ari muchikepe kana kuazadza kakawanda, zvichiita kuti rikwanise kushandiswa mumotokari dziri kure dzakadai semabhazi emuguta, mota dzepachivande, nezvimwewo.

Ndezvipi zvakanakira kushandisa gasi rechisikigo rakanyungudutswa (LNG)?
Kubva pamaonero ezvakatipoteredza, LNG ine hushamwari kune zvakatipoteredza kupfuura peturu. Kunyangwe mota dzeLNG dzichitenga mota dzekutanga dzakakwira, dzichida matangi ekuchengetera mafuta anodhura uye mainjini akasarudzika, mitengo yemafuta ayo yakaderera. Kusiyana neizvi, mota dzepeturu, kunyangwe dzichidhura zvishoma, dzine mitengo yakakwira yemafuta uye dzinokanganiswa nekuchinja-chinja kwemitengo yemafuta epasi rose. Kubva pamaonero ehupfumi, LNG ine mukana wakakura wekuvandudzwa.

Nzvimbo yekudira mafuta yegesi yechisikigo yakanyungudutswa yakachengeteka here?
Zvechokwadi. Nyika yega yega ine mitemo yakakodzera yekugadzira nzvimbo dzekuisa mafuta egasi rechisikigo dzakanyungudutswa, uye zvikamu zvekuvaka zvakakodzera zvinofanirwa kutevedzera mitemo yakasimba yekuvaka nekushanda. LNG pachayo haizoputika. Kunyangwe paine kubuda kwemvura kweLNG, inokurumidza kupararira mumhepo uye haizounganidzi pasi yokonzera kuputika. Panguva imwe chete, nzvimbo yekuisa mafuta ichashandisawo nzvimbo dzakawanda dzekuchengetedza, idzo dzinogona kuona kana paine kubuda kwemvura kana kutadza kwemidziyo.
