Alaab-qeybiyeyaal tayo sare leh oo Shiinaha Mini LNG ah - gaaska dabiiciga ah ee Liquefaction skid - Rongteng

Sharaxaada

Liquefaction gaaska dabiiciga ah, oo muddo gaaban loo yaqaan LNG, ayaa isku ururinaya gaaska dabiiciga ah dareere iyadoo la qaboojinayo gaaska dabiiciga ah ee cadaadiska caadiga ah -162 ℃. Liquefaction gaaska dabiiciga ah si weyn u badbaadin karaa meel kaydinta iyo gaadiidka, oo uu leeyahay faa'iidooyinka qiimaha calorific weyn, waxqabadka sare, ku haboon in dheelitirka xeerar culayska magaalooyinka, ku haboon ilaalinta deegaanka, yaraynta wasakhda magaalooyinka iyo wixii la mid ah.

Liquefaction waa udub dhexaadka wax soo saarka LNG. Waqtigan xaadirka ah, geeddi-socodka dareeraha gaaska dabiiciga ah ee bislaaday inta badan waxaa ka mid ah habka dareeraha cascade, habka dareeraha qaboojiyaha isku dhafan iyo habka dareeraha leh ee ballaariyaha.

Geedi socodka liquefaction gaaska dabiiciga ah ee Cascade isticmaalaa dhibco karkaraya kala duwan ee qaboojiyaha cadaadis caadiga ah si loo yareeyo heerkulka qaboojiyaha tallaabo tallaabo tallaabo si loo gaaro ujeedada liquefaction gaaska dabiiciga ah.

Wareegga qaboojiyaha isku dhafan (MRC) waa habraaca in ka badan shan nooc oo qaboojiyeyaal badan oo isku dhafan, sida C1 ~ C5 Hydrocarbons iyo N2, loo isticmaalo dareeraha shaqada si ay isugu ururiyaan, u uumi iyo ballaadhiyaan tallaabo tallaabo si loo helo awoodda qaboojinta heerkul kala duwan, ka dibna si tartiib tartiib ah u qaboojiso oo dareere gaaska dabiiciga ah. Habka dareeraha qaboojiyaha ee isku dhafan ayaa loo qaybiyaa noocyo badan oo kala duwan oo wareegga qaboojiyaha.

Geedi socodka liquefaction ee ballaarinta waxaa loola jeedaa habka of liquefaction gaaska dabiiciga ah iyadoo la isticmaalayo qaboojiyaha cadaadis sare si ay u xaqiiqsadaan rogaal celis wareeg Claude la adiabatic ballaarinta turbo ballaarinta.

Nidaamka nidaamka inta badan waxaa ka mid ah: quudinta cadaadiska gaaska nidaaminta iyo unugga cabbiraadda, unugga sifaynta gaaska dabiiciga ah iyo unugga dareeraha gaaska dabiiciga ah, nidaamka kaydinta qaboojiyaha, nidaamka isku-wareejinta qaboojiyaha, kaydinta LNG iyo unugga rarka.

Gaaska dabiiciga ah ee soo galaya saldhigga ayaa marka hore soo mara cadaadiska nidaaminta iyo cabbirka, kaas oo ogaanaya xakamaynta cadaadiska iyo cabbirka gaaska dabiiciga ah ee soo galaya; Gaaska dabiiciga ah waxa uu galaa qaybta sifaynta gaaska dabiiciga ah, halkaas oo gaaska dabiiciga ahi ay ku xiran tahay ka saarida CO2, ka saarista H2S iyo daaweynta fuuqbaxa. Habka MDEA waxaa lagula talinayaa kaarboonization iyo ka saarista H2S, habka fuuqbaxa shaandho molecular oo leh saddex munaaradood AMA habka fuuqbaxa TEG ayaa lagula talinayaa fuuqbaxa; Waxaana lagu talinayaa in loo isticmaalo BOG la soo kabsaday oo la cadaadiyo gaaska dib u soo kabashada;

Gaaska dabiiciga ah ee la safeeyey oo galay unugga dareeraha gaaska dabiiciga ah, qaboojiye isku dhafan (habraaca dareeraha MRC) ayaa lagula talinayaa dareeraha gaaska dabiiciga ah; LNG liquefied waxa lagu kaydiyaa haanta kaydinta, iyo habka kaydinta jawiga iyo heerkulka hooseeya ayaa lagula talinayaa kaydinta LNG. Mid ka mid ah haanta kaydinta heerkulka hooseeya ee jawiga ayaa ku qalabaysan kombaresarada BG, iyo kombaresarada BOG waxaa loo isticmaalaa in lagu cadaadiyo BOG ka hor inta aan la gelin qalajiyaha shaandheeyaha molecular Regeneration, taas oo ku xidhan bamka cryogenic si loo gaaro rakibid.
