Kodi ndi zinthu ziti zofunika pakupanga fakitale yothira mpweya wachilengedwe?

(1) Kodi LNG ndi chiyani?

Mpweya wachilengedwe ukazizira kufika pa -162 ℃ pansi pa mphamvu yachibadwa, umasintha kuchoka pa mkhalidwe wa mpweya kupita ku mkhalidwe wamadzimadzi, womwe umatchedwa mpweya wachilengedwe wosungunuka (LNG mwachidule).

(2) Zigawo zazikulu za LPG ndi (propane ndi butane).

(3) Mpweya wa asidi mu mpweya wachilengedwe umatanthauza (carbon dioxide ndi hydrogen sulfide).

(4) Kodi ndi zinthu ziti zofunika pakupanga fakitale yothira mpweya wachilengedwe?

Yankho:

mphamvu yopangira fakitale (mphamvu yogwiritsira ntchito mpweya wodyetsa chakudya kapena LNG yotulutsa);

Kuphatikizika kwa mpweya wodyetsa;

Mafotokozedwe a malonda;

Malo okhala ndi zinthu zachilengedwe;

Zothandizira zilipo pamalopo;

Kupereka zida kapena polojekiti ya EPC;

Zofunikira pa ntchito zaukadaulo.

(5) Pali njira ziwiri zazikulu zochotsera mpweya wachilengedwe m'thupi (njira ya triethylene glycol) ndi (njira ya molecular sieve).

(6) Ngati pakufunika kutaya madzi m'thupi kwambiri, ayenera kuchotsedwa pogwiritsa ntchito njira ya mamolekyulu.

(7) Fotokozani mwachidule cholinga cha kubwezeretsanso mphamvu ya hydrocarbon ya gasi wachilengedwe?

Yankho: pofuna kuwongolera mame a mpweya wachilengedwe kuti akwaniritse zofunikira pa kutumiza mpweya wachilengedwe. Zinthu zamadzimadzi za hydrocarbon zomwe zapezedwa zitha kugwiritsidwa ntchito ngati mafuta abwino kwambiri kapena zopangira mankhwala, ndipo zimakhala ndi phindu lalikulu pazachuma.

(8) Mayina a Chitchaina a NGL ndi LNG ndi (mpweya wachilengedwe wosungunuka) ndi (mpweya wachilengedwe wosungunuka) motsatana.

(9) Ngati mpweya wachilengedwe ukufunika kukhala wochepa kuposa -40 ℃, TEG iyenera kugwiritsidwa ntchito pochotsa madzi m'thupi.

(10) Cholinga cha kuchotsa CO2 mu gasi wachilengedwe ndikuletsa kuzizira ndi kutsekeka pa kutentha kochepa.

(11) Ndi magawo ati oyambira omwe ayenera kuperekedwa popanga skid yolekanitsa mayeso ya magawo atatu?

Yankho:

Malo olowera: zigawo za mafuta osakonzedwa, madzi a m'munda wamafuta ndi mpweya wogwirizana nawo, zinthu zakuthupi (kuchuluka, kukhuthala, ndi zina zotero), kuchuluka kwa sulfure, kuchuluka kwa mchenga ndi kugawa kwa tinthu ta mchenga

Kutentha kwapakati kolowera

Kuthamanga kwapakati kolowera

Mphamvu yochizira gawo lamadzimadzi: kuyenda kwa mafuta osakonzedwa ndi madzi

Kuchuluka kwa chithandizo cha gawo la mpweya: kuyenda kwa mpweya wachilengedwe (kuyenda kwabwinobwino kwa mkhalidwe)
