Indasitiri yeLNG yeChina yakagadzira ketani yemaindasitiri yakakwana kubva pakunyungudutsa, kutakurwa, kugadzira gasi remagetsi kusvika pakushandiswa kwemagetsi, uye kukurumidza kwayo kukura kuri kuwedzera kukwana, zvichiisa hwaro hwakanaka hwekuvandudza kushandiswa kwegasi rechisikigo muChina. Parizvino, nzvimbo gumi neina dzeLNG dzemahombekombe dzakavakwa uye dziri kuvakwa muChina, uye huwandu hwese hwekugamuchira huchapfuura matani mamiriyoni makumi mashanu / gore mushure mekunge zvese zvapedzwa. Kuchine mapurojekiti akati wandei ari kuitwa pakutanga ⑴. Nzvimbo dzemvura, nzvimbo dzesatellite uye kudira mafuta mumotokari nengarava zviri kukurawo nekukurumidza. Kubva muna Chivabvu 2013, nzvimbo dzinopfuura makumi mashanu dzemvura dzakavakwa uye dzakatanga kushanda munyika yese, dzine huwandu hwemvura inosvika mamiriyoni makumi maviri nematatu m3 / pazuva. Hunhu hwekuchengetera LNG pa -162 ℃ uye kumanikidzwa kwakajairika, mamiriro ekufambisa akakosha, kuchinja kwekumanikidzwa kwetangi rekuchengetera LNG panguva yekuburitsa nekuzadza, kupisa kwetangi rekuchengetera nemapaipi, nezvimwewo, zvichaburitsa huwandu hwakawanda hwegasi rakapfava, kureva bog. Kuti ngarava dzekutakura dzishande zvakanaka, matangi ekuchengetera zvinhu nemapaipi arambe achishanda zvakanaka, zvakakosha kufunga nezvekugadzirisa matangi akawanda uye kuchengetedza kuenzana kwesimba remagetsi kuti kumanikidzwa kurambe kuri mukati menzvimbo yakachengeteka yekudzora. Saka, kuitira kuchengetedza simba remagetsi, nzira yekurapa matangi pasi pemamiriro akasiyana inodzidzwa kuti ivandudze huwandu hwekudzoreredza matangi uye kuderedza marara egasi rechisikigo.
Dhizaini yemaitiro maviri
Kune nzvimbo yekugamuchira 4 x 160000m3, mwero wekubuda kwemvura pazuva ndeye 0. Zvichienderana nekuverengwa kwe05%, kubuda kwemvura kwezuva nezuva kweLNG kunosvika 320 cubic metres, uye bog rinogadzirwa rinosvika 192000 cubic metres, anenge 144 matani pazuva; Pasi pemamiriro ekuburitsa zvinhu, huwandu hwebog hunogadzirwa nekutsinhana kwetembiricha uye kuchinja kwekumanikidzwa huchava kakawanda kana kunyange kagumi kupfuura mumamiriro echinyakare. Kurapa bog nenzira inonzwisisika hakungoderedzi kukuvara kunogona kuitika kumidziyo nevashandi chete, asiwo kuchengetedza simba, kuderedza kushandiswa uye kuderedza mutengo.
Kuti tidzidze maitiro ekurapa bog mumamiriro akasiyana, tichitora nzvimbo yekugamuchira nesatellite station semuenzaniso, sarudzo yemaitiro acho inotariswa kubva pahuwandu hwebog. Tora nzvimbo yekugamuchira muFujian (matangi ekuchengetera 4 x 160000m3) uye nzvimbo yesatellite muShandong (matangi ekuchengetera 10 100m3). Hwaro hwekufananidza: mhando dzakasiyana dzematangi dzine mwero wakasiyana wekubuda kwemvura, uye nzira dzakasiyana dzekurapa dzichakanganisa kugadziriswa kwebog kunotevera. Maitiro akakodzera ekurapa anofanira kusarudzwa kune mhando dzakasiyana dzematangi uye zviyero zvekurapa zveLNG.
3 Kurapwa kwechinyakare kwedongo
Kazhinji kune nzira ina dzekurapa dhaka rinogadzirwa, imwe ndeyekudzoreredza mvura; Chechipiri, kudzvanya zvakananga; 3. Kupisa kana kuburitsa mhepo; Chechina, kudzorera kugedhi reLNG.
(1) Maitiro ekugadzirisazve kutonhora kwemvura. Mushure mekupfuura nepatangi rekuparadzanisa gasi nemvura, chirongo chinopinda mucompressor yechirongo. Chirongo chine kumanikidzwa chinopinda muRecondenser uye chinosanganiswa neLNG inotumirwa kunze iyo inomanikidzwa kusvika pakumanikidzwa kwakafanana. Chirongo chinosanganiswa nekukwanisa kutonhora kunotakurwa neLNG yakatonhodzwa zvakanyanya uye chinosanganiswa neLNG by-pass mupombi ine kumanikidzwa kwakawanda, uye chobva chapiswa nevaporizer uye chinotumirwa kune network yepombi ine kumanikidzwa kwakakwira (2). Chati yekuyerera kwemaitiro ekudzokorora kwechiteshi inoratidzwa muMufananidzo 1.
(2) Maitiro ekudzvanya zvakananga. Bog inoburitswa zvakananga kune network yepombi mushure mekudzvanywa necompressor.
(3) Kupisa kana kuburitsa mweya. Kana kumanikidzwa kuri mutangi nekabhini kwasvika padanho rakati, kupiswa kwemhepo kana kupiswa kwemhepo kunowanzo shandiswa kuderedza kumanikidzwa kusvika panzvimbo yakachengeteka uye inodzorwa. Kupisa mhepo kana kupiswa kwemhepo kuchava kutambisa gasi rechisikigo. Saka, nzira iyi inzira yekuchengetedza kana paine emergency.
(4) Bog inotakurwa kuenda kungarava yeLNG kuburikidza neruoko rwekudzosera kuti ienzanise kumanikidzwa uye izadze vacuum inogadzirwa nekuburitsa tangi rekuchengetera LNG riri muchikepe. Nzira iyi iri nyore uye inokurumidza, asi yakakodzera chete kuburitsa ngarava yeLNG.
