Shimbiraha gaaska dabiiciga ah ee la shiiday

Sharaxaad

Gaaska dabiiciga ah ee Liquefaction, oo si kooban loogu yeero LNG, ayaa gaaska dabiiciga ah u rogaya dareere isagoo qaboojinaya gaaska dabiiciga ah ee gaaska leh cadaadis caadi ah ilaa - 162 ℃. Liquefaction gaaska dabiiciga ah wuxuu si weyn u badbaadin karaa booska kaydinta iyo gaadiidka, wuxuuna leeyahay faa'iidooyinka qiimaha kalooriga weyn, waxqabadka sare, oo ku habboon dheelitirka xakamaynta culeyska magaalooyinka, oo ku habboon ilaalinta deegaanka, yaraynta wasakhowga magaalooyinka iwm.

Daadinta waa xudunta wax soo saarka LNG. Waqtigan xaadirka ah, hababka daadinta gaaska dabiiciga ah ee bislaaday waxay inta badan ka kooban yihiin habka daadinta cascade, habka daadinta qaboojiyaha isku dhafan iyo habka daadinta oo leh fidiye.

Habka dareeraha gaaska dabiiciga ah ee Cascade wuxuu adeegsadaa dhibco karkaraya oo kala duwan oo qaboojiyaha ah cadaadis caadi ah si loo yareeyo heerkulka qaboojiyaha tallaabo tallaabo si loo gaaro ujeeddada dareeraha gaaska dabiiciga ah.

Wareegga qaboojiyaha isku dhafan (MRC) waa hab lagu isticmaalo in ka badan shan nooc oo qaboojiyeyaal isku dhafan oo qaybo badan leh, sida C1 ~ C5 Hydrocarbons iyo N2, oo loo isticmaalo dareere shaqeynaya si loo ururiyo, loo uumi-baxo loona ballaariyo tallaabo tallaabo si loo helo awoodda qaboojinta heerarka heerkulka kala duwan, ka dibna si tartiib tartiib ah loogu qaboojiyo oo loo shubo gaaska dabiiciga ah. Habka dareeraha qaboojiyaha isku dhafan waxaa loo qaybiyaa noocyo badan oo kala duwan oo wareegga qaboojinta ah.

Habka dareeraha ee leh ballaarinta waxaa loola jeedaa habka dareeraha gaaska dabiiciga ah iyadoo la adeegsanayo qaboojiyaha cadaadiska sare leh si loo xaqiijiyo qaboojiyaha wareegga Claude ee dib u soo noqnoqda oo leh ballaarinta adiabatic ee ballaarinta turbo.

Nidaamka geeddi-socodka waxaa inta badan ka mid ah: cutubka nidaaminta cadaadiska gaaska quudinta iyo cabbiraadda, cutubka nadiifinta gaaska dabiiciga ah iyo cutubka dareeraha gaaska dabiiciga ah, nidaamka kaydinta qaboojiyaha, nidaamka cadaadiska wareegga qaboojiyaha, cutubka kaydinta LNG iyo rarista.

Gaaska dabiiciga ah ee soo galaya saldhigga ayaa marka hore mara qaybta nidaaminta cadaadiska iyo cabbiraadda, taas oo xaqiijinaysa nidaaminta cadaadiska iyo cabbiraadda gaaska dabiiciga ah ee soo socda; Gaaska dabiiciga ah wuxuu galaa qaybta nadiifinta gaaska dabiiciga ah, halkaas oo gaaska dabiiciga ah uu ku xiran yahay ka saarista CO2, ka saarista H2S iyo daaweynta fuuqbaxa. Habka MDEA waxaa lagu talinayaa in la baabi'iyo kaarboonaynta iyo ka saarista H2S, habka fuuqbaxa shaandhada molecular-ka oo leh saddex taar AMA habka fuuqbaxa TEG ayaa lagu talinayaa fuuqbaxa; Waxaana lagu talinayaa in la isticmaalo BOG la soo celiyey oo la cadaadiyey gaaska dib u soo kabashada;

Gaaska dabiiciga ah ee la sifeeyay ee lagu shubay qaybta dareeraha gaaska dabiiciga ah, qaboojiyaha isku dhafan (habka dareeraha MRC) ayaa lagula talinayaa cabitaanka gaaska dabiiciga ah; LNG-ga dareeraha ah ayaa lagu kaydiyaa haanta kaydinta, habka kaydinta jawiga iyo heerkulka hooseeyana waxaa lagula talinayaa kaydinta LNG. Hal haan kaydin heerkul hoose leh oo jawiga ah ayaa lagu qalabeeyay kombaresarada BG, kombaresarada BOG-na waxaa loo isticmaalaa in lagu cadaadiyo BOG ka hor inta aan la gelin qalajiyaha shaandhada molecular-ka Dib-u-soo-noolaynta, iyadoo ku xiran bamka cryogenic si loo gaaro rakibidda.
