Mpweya Wachilengedwe Wosungunuka (LNG) umagwira ntchito yofunika kwambiri pakupanga mphamvu padziko lonse lapansi, kupereka njira ina yoyera m'malo mwa mafuta akale. Komabe, kunyamula LNG bwino komanso mosamala kumafuna ukadaulo wapamwamba, ndipochitoliro chotenthetsera cha vacuum(VIP)yakhala yankho lofunika kwambiri pankhaniyi.

Kumvetsetsa LNG ndi Mavuto Ake Oyendera

LNG imazizira mpweya wachilengedwe kufika pa -162°C (-260°F), zomwe zimachepetsa kuchuluka kwake kuti kusungidwe ndi kunyamulidwa mosavuta. Kusunga kutentha kotsika kwambiri kumeneku ndikofunikira kuti tipewe kupsa ndi nthunzi panthawi yoyenda. Mayankho achikhalidwe a mapaipi nthawi zambiri amalephera chifukwa cha kutayika kwa kutentha, zomwe zimapangitsa kuti pakhale kusagwira ntchito bwino komanso zoopsa zina.Mapaipi otetezedwa ndi vacuumkupereka njira ina yolimba, kuonetsetsa kuti kutentha kochepa komanso kuteteza umphumphu wa LNG mu unyolo wonse woperekera magetsi.

 

Chifukwa chiyaniMapaipi Otetezedwa ndi VacuumNdi Ofunika Kwambiri

Mapaipi otetezedwa ndi vacuumZapangidwa ndi makoma awiri, komwe malo pakati pa makoma amkati ndi akunja amachotsedwa kuti apange vacuum. Kapangidwe kameneka kamachepetsa kusamutsa kutentha mwa kuchotsa njira zoyendetsera mpweya ndi zolumikizira mpweya.

Ubwino waukulu ndi monga:
1. Kuteteza Kutentha Kwambiri:Amaonetsetsa kuti LNG imakhalabe mumadzimadzi patali.
2.Ndalama Zotsika Zogwirira Ntchito:Amachepetsa mpweya woipa (BOG), amachepetsa kutayika kwa zinthu komanso amawonjezera kugwiritsa ntchito bwino ndalama.
3.Chitetezo Chowonjezereka:Zimaletsa chiopsezo cha kupanikizika kwambiri chifukwa cha kupsa kwa LNG.

1.Malo Osungira Zinthu a LNG:Ma VIP ndi ofunikira kwambiri potumiza LNG kuchokera ku matanki osungiramo zinthu kupita ku magalimoto onyamula popanda kusinthasintha kwa kutentha
2.Mayendedwe a LNG:Amagwiritsidwa ntchito kwambiri m'malo osungira mafuta a LNG m'madzi, anthu olemekezeka amatsimikizira kuti mafuta amaperekedwa bwino komanso motetezeka pa sitima.
3.Kugwiritsa Ntchito Mafakitale:Ma VIP amagwira ntchito m'mafakitale opangira magetsi pogwiritsa ntchito LNG, zomwe zimathandiza kuti mafuta aperekedwe bwino.

 

Tsogolo laMapaipi Otetezedwa ndi Vacuummu LNG

Pamene kufunikira kwa LNG kukukulirakulira, mapaipi otetezedwa ndi vacuumali okonzeka kutenga gawo lofunika kwambiri pakukweza magwiridwe antchito ndi kukhazikika. Zatsopano mu zipangizo ndi kupanga zikuyembekezeka kupititsa patsogolo magwiridwe antchito awo komanso kugwiritsa ntchito bwino ndalama, zomwe zimapangitsa kuti LNG ikhale yankho labwino kwambiri la mphamvu padziko lonse lapansi.

 

Ndi mphamvu zosayerekezeka zotetezera kutentha,mapaipi otetezedwa ndi vacuumakusinthiratu makampani opanga magetsi a LNG, kuonetsetsa kuti kugwiritsa ntchito bwino mphamvu ndi chitetezo kumakhalabe patsogolo. Kupitiliza kugwiritsa ntchito kwawo mosakayikira kudzasintha tsogolo la mayendedwe amagetsi oyera.
