1 Isingeniso
Imboni ye-LNG yaseShayina yakhe uchungechunge lwezimboni oluphelele kusukela ekukhiqizweni koketshezi, ezokuthutha, ukufakelwa kwegesi endaweni yokugcina kuya ekusetshenzisweni kwendawo yokugcina, futhi isivinini sayo sokuthuthukiswa nokuvuthwa kuya ngokuya kuphelela, okubeka isisekelo esihle sentuthuko yokusetshenziswa kwegesi yemvelo eShayina. Njengamanje, kwakhiwe izikhungo ze-LNG ezingu-14 ezisogwini futhi ziyakhiwa eShayina, futhi umthamo wokwamukela wonke uzodlula amathani ayizigidi ezingama-50 / ngonyaka ngemuva kokuba konke sekuqediwe. Kusenamaphrojekthi amaningana angaphansi komsebenzi wokuqala ⑴. Izitshalo zokufaka uketshezi, iziteshi zesathelayithi kanye nokugcwalisa uphethiloli wezimoto nemikhumbi nakho kukhula ngokushesha. Kusukela ngoMeyi 2013, izikhungo zokufaka uketshezi ezingaphezu kuka-50 zakhiwe futhi zaqala ukusebenza ezweni lonke, ezinomthamo wokufaka uketshezi ophelele ongu-23 million m3 / ngosuku. Izici zokugcina i-LNG ku--162 ℃ kanye nokucindezela okuvamile, izimo zokuhamba ezikhethekile, ushintsho lokucindezela kwethangi lokugcina i-LNG ngesikhathi sokulayisha nokugcwalisa, ukuvuza kokushisa kwethangi lokugcina kanye nepayipi, njll., kuzokhiqiza inani elikhulu legesi eliphefumulayo, okungukuthi i-bog. Ukuze kuvikelwe ukusebenza okuvamile nokuphepha kwemikhumbi yezokuthutha, amathangi okugcina kanye namapayipi, kubalulekile ukucabangela ukuphathwa kwenqwaba yama-bog nokugcina ibhalansi enamandla yokucindezela ukuze kugcinwe ingcindezi ngaphakathi kwebanga lokulawula eliphephile. Ngakho-ke, ngenhloso yokuphepha kokusebenza nokonga amandla, inqubo yokwelapha i-bog ngaphansi kwezimo ezahlukene iyafundwa ukuze kuthuthukiswe izinga lokubuyiselwa kwe-bog nokunciphisa imfucuza yegesi yemvelo.
Umklamo wezindlela ezimbili
Esiteshini sokwamukela esingu-4 x 160000m3, izinga lokuhwamuka kwansuku zonke lingu-0 Ngokusho kokubalwa okungu-05%, ukuhwamuka kwansuku zonke kwe-LNG kungaba ngama-cubic metres angu-320, kanti i-bog ekhiqizwayo ingaba ngama-cubic metres angu-192000, cishe amathani angu-144 ngosuku; Ngaphansi kwesimo sokukhulula, inani le-bog ekhiqizwa ukushintshana kwezinga lokushisa kanye nokushintsha kwengcindezi lizoba izikhathi eziningana noma ngisho neziyishumi kunaleso esivamile. Ukwelapha i-bog ngenqubo efanele akugcini nje ngokunciphisa umonakalo ongaba khona emishinini nakubasebenzi, kodwa futhi konga amandla, kunciphise ukusetshenziswa futhi kunciphise izindleko.
Ukuze kufundwe inqubo yokwelapha i-bog ngaphansi kwezimo ezahlukene, uma kuthathwa isiteshi sokwamukela kanye nesiteshi sesathelayithi njengesibonelo, ukukhethwa kwenqubo kubhekwa kusukela enanini le-bog. Thatha isiteshi sokwamukela eFujian (amathangi okugcina angu-4 x 160000m3) kanye nesiteshi sesathelayithi eShandong (amathangi okugcina angu-10 angu-100m3). Isisekelo sokufanisa: izinhlobo ezahlukene zamathangi zinezinga elihlukile lokuhwamuka, futhi izindlela ezahlukene zokwelapha zizothinta ukucutshungulwa okulandelayo kwe-bog. Inqubo efanele yokwelapha kufanele ikhethwe ngezinhlobo ezahlukene zamathangi kanye nezikali zokwelashwa ze-LNG.
3 Ukwelashwa okuvamile kwedaka
Ngokuvamile kunezindlela ezine zokwelapha i-bog ekhiqizwe, eyodwa ukuvuselela umswakama; Okwesibili, ukucindezela okuqondile; 3. Ukushisa noma ukungenisa umoya; Okwesine, ukubuyisela ku-LNG carrier.
(1) Inqubo yokwelapha kabusha ukujiya. Ngemva kokudlula ethangini lokuhlukanisa igesi noketshezi, i-bog ingena kwi-compressor ye-bog. I-bog ecindezelwe ingena kwi-Recondenser futhi ixutshwa ne-LNG ethunyelwe kwamanye amazwe ecindezelwe kungcindezi efanayo. I-bog icindezelwa amandla okupholisa athwalwa yi-LNG epholile kakhulu futhi ixutshwe ne-LNG by-pass ephampini yokucindezela okuphezulu, bese iqiniswa yi-vaporizer bese idluliselwa kunethiwekhi yamapayipi okucindezela okuphezulu (2). Ishadi lokugeleza kwenqubo yokuphinda iqiniswe le-terminal liboniswe kuMfanekiso 1.
(2) Inqubo yokucindezela ngqo. I-Bog ikhishwa ngqo kunethiwekhi yamapayipi ngemva kokucindezelwa yi-compressor.
(3) Ukusha noma ukukhipha umoya. Lapho ingcindezi ethangini nasekhabini ifinyelela inani elithile, ukusha komoya noma ukuqhuma komoya kuvame ukusetshenziswa ukuze kuncishiswe ingcindezi ibe sebangeni eliphephile nelilawulekayo. Ukusha noma ukukhipha umoya noma ukuqhuma komoya kuzoba ukuchitha igesi yemvelo kakhulu. Ngakho-ke, le ndlela iyisilinganiso sokwelashwa kokuphepha uma kwenzeka isimo esiphuthumayo.
(4) I-Bog ithuthwa iye emkhunjini we-LNG ngengalo yokubuyisa ukuze ilinganisele ingcindezi futhi igcwalise i-vacuum ekhiqizwa ukuthulula ithangi lokugcina i-LNG ebhodini. Le ndlela ilula futhi iyashesha, kodwa ifaneleka kuphela ekuthululweni kwemikhumbi ye-LNG.
