1. Nhanganyaya
Indasitiri yeChina yeLNG yakagadzira chiketani chakazara cheindasitiri kubva pakunyunguduka, kufambisa, terminal gasification kusvika kushandiswa kwekupedzisira, uye kukurumidza kwekukura kwayo uye kukura kuri kuramba kuchiwedzera kukwana, ichiisa hwaro hwakanaka hwebudiriro yekushandiswa kwepasi kwegasi rechisikigo muChina. Parizvino, gumi nemana emahombekombe LNG zviteshi zvakavakwa uye zviri kuvakwa muChina, uye huwandu hwekugamuchira huchapfuura 50million matani / gore mushure mekunge zvese zvapera. Pachine akati wandei mapurojekiti pasi pebasa rekutanga ⑴. Liquefaction zvidyarwa, satellite zviteshi uye mota uye ngarava refueling zviri kukurawo nekukurumidza. Kubva munaMay2013, zvinopfuura makumi mashanu zvidyarwa zvekunyungudutsa zvakavakwa uye zvakaiswa mukushanda munyika yese, iine huwandu hwese hwekuita liquefaction hwe23million m3 / zuva. LNG kuchengetedza maitiro pa -162 ℃ uye yakajairwa kudzvanywa, yakakosha mamiriro ekufambisa, shanduko yekuchinja kweLNG yekuchengetera tangi panguva yekuburitsa nekuzadza, kupisa kunobuda kwetangi rekuchengetedza uye pombi, nezvimwewo, inoburitsa huwandu hukuru hwegasi rakaputirwa, iro bog. Kuti uchengetedze kushanda kwakajairwa uye kuchengetedzeka kwezvikepe zvekutakura, matangi ekuchengetedza uye mapaipi, zvinodikanwa kufunga nezve kurapwa kwenhamba yakawanda yemabhogi uye kuchengetedza kusimba kwesimba rekumanikidza kuchengetedza kudzvanywa mukati meiyo yakachengeteka control range. Nokudaro, nokuda kwechinangwa chekuchengetedzwa kwekushanda uye kuchengetedza simba, nzira yekurapa yebhogi pasi pemamiriro akasiyana-siyana inodzidzwa kuti ivandudze chiyero chekudzorera chebhogi uye kuderedza kutambisa gasi rechisikigo.
2 nzira dhizaini
Kune 4 x 160000m3 yekugamuchira chiteshi, zuva nezuva evaporation rate ndeye 0 Maererano nekuverenga kwe05%, zuva nezuva LNG evaporation inenge 320 cubic metres, uye iyo yakagadzirwa bog inenge 192000 cubic metres, inenge 144 matani / zuva; Pasi pemamiriro ekudzikisa, huwandu hwebhogi hunogadzirwa nekutsinhanisa tembiricha uye shanduko yekumanikidza ichave yakawanda kana kunyange kagumi pane iyo yakajairika mamiriro. Kurapa bog nemaitiro anonzwisisika hakungogone kuderedza kukuvadzwa kwemidziyo nevashandi, asiwo kuchengetedza simba, kuderedza kushandiswa uye kuderedza mutengo.
Kuti udzidze nzira yekurapa yebhogi pasi pemamiriro akasiyana, kutora chiteshi chekugamuchira uye satellite station semuenzaniso, kusarudzwa kwemaitiro kunoonekwa kubva muhuwandu hwebhogi. Tora chiteshi chekugamuchira muFujian (4 x 160000m3 matangi ekuchengetedza) uye satellite chiteshi muShandong (10 100m3 matangi ekuchengetedza). Nheyo yekufananidza: akasiyana matangi marudzi ane akasiyana evaporation mareti, uye nzira dzakasiyana dzekurapa dzinokanganisa kunotevera kugadzirisa kwebhogi. Yakakodzera nzira yekurapa ichasarudzirwa akasiyana matangi marudzi uye LNG kurapa zviyero.
3 kurapa kwakajairika bog
Kune kazhinji nzira ina dzekurapa dzeiyo yakagadzirwa bog, imwe ndeye re condensation; Chechipiri, kudzvinyirirwa kwakananga; 3. Kupisa kana mhepo; Chechina, dzokera kune LNG mutakuri.
(1) Re-condensation kurapwa maitiro. Mushure mokupfuura negasi-mvura yekuparadzanisa tangi, bhogi inopinda mubhogi compressor. Iyo yakamanikidzwa bog inopinda muRecondenser uye inosanganiswa neiyo LNG inotumirwa kunze iyo inomanikidzwa kune imwechete kumanikidza. Iyo bhogi inodzorwa nekutonhodza simba inotakurwa neiyo supercooled LNG uye yakasanganiswa neLNG by-pass kupinda mupombi inodzvanywa, uye yobva yafemeswa nevaporizer uye yoendeswa kune yakanyanya-pressure pombi network (2). Iyo recondensation process inoyerera chati yeiyo terminal inoratidzwa muMufananidzo 1.
(2) Direct compression process. Bog inobuda yakananga kune pombi network mushure mekumanikidzwa ne compressor.
(3) Kupisa kana kubuda mhepo. Kana dzvinyiriro mutangi nekabhini ichisvika pane imwe kukosha, vent kana flare combuss inowanzo gamuchirwa kudzikisa kudzvanywa kune yakachengeteka uye inodzoreka renji. Kupisa kana kupisa kwemoto kuchave kutambisa kukuru kwegasi rechisikigo. Naizvozvo, iyi nzira inzira yekuchengetedza kurapa kana paine emergency.
(4) Bog inotakurwa kuenda kuLNG ngarava kuburikidza nekudzoka ruoko kudzikamisa kudzvanywa uye kuzadza vacuum inogadzirwa nekuburitsa LNG yekuchengetera tangi pabhodhi. Iyi nzira iri nyore uye inokurumidza, asi yakakodzera chete kuburitsa ngarava yeLNG.
