Ibisobanuro

Umwuka wa gazi ya gazi, bita LNG, uhuza gaze gasanzwe mumazi ukonjesha gaze gasanzwe munsi yumuvuduko ukabije kugeza - 162 ℃. Kuvomera gazi karemano birashobora kuzigama cyane ahantu ho guhunika no gutwara abantu, kandi bifite ibyiza byagaciro gakomeye ka calorifique, imikorere myiza, bifasha kuringaniza kugenzura imitwaro yo mumijyi, bifasha kurengera ibidukikije, kugabanya umwanda mumijyi nibindi.

Amazi ni ishingiro ryumusaruro wa LNG. Kugeza ubu, uburyo bwa gazi ya gazi ikuze ikuze cyane cyane harimo uburyo bwo kuyungurura caskade, uburyo bwo kuvanga firigo ivanze nuburyo bwo kuyungurura hamwe niyaguka.

Cascade isanzwe ya gazi ya gazi ikoresha ingingo zitandukanye zitetse za firigo munsi yumuvuduko usanzwe kugirango igabanye ubushyuhe bwa firigo intambwe ku yindi kugirango igere ku ntego yo kuvoma gaze gasanzwe.

Uruvange rwa firigo (MRC) ni inzira aho ubwoko burenga butanu bwamafiriti avanze ya firigo nyinshi, nka C1 ~ C5 Hydrocarbone na N2, bikoreshwa nkamazi akora kugirango yegeranye, ahumeka kandi yongere intambwe ku yindi kugirango abone ubushobozi bwo gukonjesha kurwego rwubushyuhe butandukanye, hanyuma gahoro gahoro gahoro gahoro. Inzira ya firigo ivanze igabanijwemo ubwoko bwinshi butandukanye bwa firigo.

Igikorwa cyo kuyungurura hamwe niyaguka bivuga inzira yo kuvoma gaze gasanzwe ukoresheje firigo yumuvuduko mwinshi kugirango umenye ubukonje bwa Claude cycle hamwe no kwaguka kwa adiabatic kwagura turbo.

Gahunda y'ibikorwa ikubiyemo cyane cyane: kugaburira gazi kugaburira no gupima, ishami risukura gazi karemano hamwe na gazi ya gazi isanzwe, sisitemu yo kubika firigo, sisitemu yo gukwirakwiza firigo, ububiko bwa LNG nububiko.

Gazi isanzwe yinjira kuri sitasiyo ibanza kunyura mumashanyarazi agenzura no gupima, ikamenya kugenzura umuvuduko no gupima gaze karemano yinjira; Gazi isanzwe yinjira murwego rusukura gazi isanzwe, aho gaze gasanzwe ishobora gukurwaho CO2, kuvanaho H2S no kuvura umwuma. Gahunda ya MDEA irasabwa gukuraho decarbonisation no kuvanaho H2S, uburyo bwo kubura umwuma wa molekile hamwe numunara itatu CYANGWA TEG yo kubura amazi birasabwa kubura umwuma; Kandi birasabwa gukoresha BOG yagaruwe kandi ikomye kuri gaze nshya;

Gazi isanzwe isukuye mumashanyarazi ya gazi karemano, firigo ivanze (MRC liquefaction process) irasabwa kuvoma gaze naturel; LNG isukuye ibikwa mu kigega cyo kubikamo, kandi uburyo bwo kubika ikirere n’ubushyuhe buke birasabwa kubika LNG. Ikigega kimwe cyo mu kirere gifite ubushyuhe buke gifite ibikoresho bya compressor ya BG, na compressor ya BOG ikoreshwa mu kotsa igitutu BOG mbere yo kwinjira mu cyuma cyumisha cyuma cyitwa Regeneration, bitewe na pompe ya kirogenike kugirango igere ku iyinjizwa.
