LNG ndiyo chidimbu cheChirungu Liquefied Natural Gas, kureva, gasi remusikirwo rakanyungudutswa.Icho chigadzirwa chekutonhodza uye kunyunguduka kwegasi rechisikigo (methane CH4) mushure mekucheneswa uye kupisa kwakanyanya-pasi (-162 ° C, imwe mhepo yemhepo).Huwandu hwegasi rakanyungudutswa hwakadzikiswa zvakanyanya, inenge 1/600 yehuwandu hwegasi rechisikigo pa0 ° C uye 1 mhepo yekumanikidza, kureva kuti, 600 cubic metres yegasi chaiyo inogona kuwanikwa mushure me1 cubic mita yeLNG iri. gasified.
Liquefied gasi rechisikigo harina ruvara uye harinhuhwi, chikamu chikuru imethane, pane zvimwe zvitsvina zvishoma, yakachena kwazvo.simba.Kuwanda kwayo kwemvura kunosvika 426kg/m3, uye gasi density inenge 1.5 kg/m3.Muganho wekuputika ndeye 5% -15% (vhoriyamu%), uye nzvimbo yekubatidza inenge 450 °C.Iyo gasi chaiyo inogadzirwa nemafuta / gasi munda inoumbwa nekubvisa mvura, asidhi, kuomeswa, fractional distillation uye yakaderera tembiricha condensation, uye vhoriyamu inoderedzwa kusvika 1/600 yepakutanga.
Nekuvandudzwa kwakasimba kwechirongwa chenyika yangu che“West-East Gas Pipeline”, kupisa kwenyika kwekushandiswa kwegasi kwakadzimwa.Sesimba resimba rakanakisa munyika, gasi rechisikigo rave richikosheswa zvakanyanya mukusarudzwa kwemadhorobha gasi masosi munyika yangu, uye kusimudzira nesimba gasi rechisikigo rave mutemo wenyika yangu.Nekudaro, nekuda kwehukuru hukuru, mari yakakwira uye nguva refu yekuvaka gasi remapaipi ekufambisa kwepombi, zvakaoma kuti mapaipi akareba asvike kumaguta mazhinji munguva pfupi.
Uchishandisa kudzvinyirirwa kwakanyanya, huwandu hwegasi rechisikigo hunoderedzwa neanenge 250 nguva (CNG) yekufambisa, uye ipapo nzira yekuidzvinyirira inogadzirisa dambudziko rezviwanikwa zvegasi mune mamwe maguta.Iko kushandiswa kweyekupedzisira-yakaderera tembiricha yefiriji tekinoroji kugadzira gasi rechisikigo kuita mvura (inenge 600 idiki muhukuru), uchishandisa ekupedzisira-yakaderera tembiricha yekutonhora ekuchengetedza matangi, kutakura gasi rechisikigo pamusoro pemadaro marefu nemotokari, zvitima, ngarava, nezvimwe. , uye wozochengeta uye kudzorera LNG mu-ultra-yakaderera tembiricha yekuchengetera matangi Kana ichienzaniswa neCNG modhi, iyo gasi yekugovera modhi ine yakakwirira kutapurirana kunyatsoshanda, kuchengetedzeka kwakasimba uye kuvimbika, uye inogona kugadzirisa zvirinani dambudziko remaguta egasi echisikigo.
Maitiro eLNG
1. Tembiricha yakaderera, hombe gasi-mvura yekuwedzera reshiyo, yakakwirira simba rekushandisa, nyore kutakura uye kuchengeta.
1 yakajairwa cubic mita yegasi chaiyo ine huwandu hwekupisa hunosvika 9300 kcal
1 tani yeLNG inogona kugadzira 1350 yakajairwa cubic metres yegasi chaiyo, inogona kuburitsa 8300 madhigirii emagetsi.
2. Simba rakachena - LNG inoonekwa seyakanyanya kuchena simba pasi pano!
Sulfur yemukati yeLNG yakaderera zvakanyanya.Kana 2.6 miriyoni matani/gore reLNG ikashandiswa kugadzira magetsi, inoderedza kuburitswa kweSO2 nematani angangoita mazana mana nemakumi mashanu ezviuru (zvinenge zvakaenzana nekaviri pagore SO2 emissions muFujian) zvichienzaniswa nemarasha (lignite).Misa kuwedzera kweasidhi mvura inonaya.
Gasi remagetsi rekugadzira simba NOX uye CO2 kuburitswa kunongova 20% uye 50% yemagetsi anopfurwa nemarasha.
Yepamusoro kuchengetedza kuita - yakatemwa neakanakisa emuviri uye makemikari zvimiro zveLNG!Mushure mekuita gasification, yakareruka kupfuura mhepo, isina ruvara, haina kunhuwa uye isina chepfu.
High ignition point: auto-ignition tembiricha inenge 450 ℃;nhete kupisa siyana: 5% -15%;yakareruka kupfuura mhepo, iri nyore kuparadzira!
Sesimba sosi, LNG ine zvinotevera maitiro:
LNG kazhinji haiburitse kusvibiswa mushure mekutsva.
Kuvimbika kwekupihwa kweLNG kunovimbiswa nekondirakiti uye kushanda kweketani yese.
Kuchengetedzeka kweLNG kunovimbiswa zvizere nekunyatsoita nhevedzano yemazinga epasi rose mukugadzira, kuvaka uye kugadzira.LNG yave ichishanda kwemakore makumi matatu pasina tsaona yakakomba.
LNG, senge sosi yesimba rekugadzira magetsi, inoenderana nepamusoro pemutemo, kushanda kwakachengeteka uye optimization yegidhi remagetsi uye kuvandudzwa kwesimba rekupa magetsi.
Sesimba remudhorobha, LNG inogona kuvandudza zvakanyanya kugadzikana, kuchengetedzeka uye hupfumi hwekugovera gasi.
Yakasiyana-siyana yekushandiswa kweLNG
Sehuni yakachena, LNG zvirokwazvo ichave imwe yenzvimbo huru dzesimba muzana ramakore idzva.Rondedzera kushandiswa kwayo, kunyanya kusanganisira:
Peak load uye tsaona peak shaving inoshandiswa kugovera gasi mumadhorobha
Inoshandiswa seyakanyanya gasi sosi yekugovera gasi pombi mumaguta makuru nepakati
Inoshandiswa segasi sosi yekuisa gasification yeLNG nharaunda
Inoshandiswa semafuta ekuwedzera mafuta emotokari
inoshandiswa sehuni dzendege
Cold simba kushandiswa kweLNG
