Njengoba inani lokuthengisa lemikhiqizo ye-LNG lishintsha ngokwesimo semakethe, umkhiqizo we-LNG udinga ukuzivumelanisa nezinguquko zemakethe. Ngakho-ke, kuphakanyiswa izidingo eziphezulu zokuqina komthwalo wokukhiqiza kanye nokugcinwa kwezitshalo ze-LNG nge-LNG.
Ukulawulwa komthwalo wokukhiqizwa kwe-LNG
Ukulawulwa kwe-Mr compressor
I-MR compressor iyi-compressor ye-centrifugal. Umthwalo wayo ungalungiswa ngokuqhubekayo phakathi kuka-50 ~ 100% ngokulungisa idivayisi yokufaka i-air inlet valve kanye ne-return valve ye-compressor.
Ukulawulwa komthwalo wesistimu yokwelashwa kwangaphambi kokwelashwa
Umthwalo womklamo weyunithi yegesi yokususa i-acid akufanele ube ngaphansi kuka-100%. Ngokwesisekelo sokulawula ingcindezi, idivayisi yesistimu yokwelapha ingalungiswa ngokuqhubekayo ngaphakathi kobubanzi bomthwalo obungu-50 ~ 110% futhi ihlangabezane nendinganiso yokwelapha nokuhlanzwa kwangaphambi kwesikhathi.
Ububanzi bokulawulwa komthwalo webhokisi elibandayo elincibilikisiwe
Umthwalo womklamo webhokisi elibandayo elimanzi akufanele ube ngaphansi kuka-100%. Uma umthwalo wedivayisi ushintsha kusuka ku-50% kuya ku-100%, i-plate heat exchanger nama-valve ebhokisini elibandayo angasebenza ngokujwayelekile futhi ahlangabezane ngokugcwele nezimo zokusebenza zomthwalo oguquguqukayo.
Ngamafuphi, ukuguquguquka kokusebenza kwedivayisi yonke kungu-50% ~ 100%. Abasebenzisi bangalungisa umthwalo wedivayisi ngaphakathi kwalolu hlu ngokuya ngesimo sokuthengisa somkhiqizo ukuze bathuthukise umnotho wokusebenza.
Ukulungiswa komthamo wokugcina wethangi lokugcina i-LNG
Ngokusho komkhiqizo we-LNG, umthamo wethangi lokugcina esilinikezayo uwumphumela we-LNG wezinsuku eziyishumi, futhi umthamo wokugcina wethangi lokugcina ungasetshenziswa ukuvimbela ushintsho lokuthengisa.
Ushintsho lokwakheka kwegesi yokuphakelayo
Ukushintsha kokwakheka kwegesi yokuphakelwa kuzoletha izinselele ekunakekelweni kwangaphambi kokwelashwa kanye noketshezi.
Impendulo yesistimu yokwelapha igesi yokuphakelayo ngaphambi kokushintsha kwezingxenye
Impendulo ye-decarbonization
Ngokusho kokuqukethwe kwe-carbon dioxide okukhona, sisebenzisa indlela ye-MDEA amine ukuze sisuse i-carbon dioxide futhi sandise ukwakheka kwe-carbon dioxide ku-3%. Inani elikhulu lokuhlangenwe nakho kobunjiniyela okusebenzayo lifakazele ukuthi lo mklamo ungavumelana noshintsho lokuqukethwe kwe-carbon dioxide futhi ususe i-carbon dioxide ezingeni lika-50ppm.
Ukususwa kwe-hydrocarbon esindayo
Ama-hydrocarbon asindayo kugesi yemvelo ikakhulukazi yi-neopentane, i-benzene, ama-hydrocarbon aromatic kanye nezingxenye ezingaphezu kwe-hexane ezilimaza inqubo ye-cryogenic yebhokisi elibandayo. Uhlelo lokususa esilwamukelayo luyindlela yokumunca i-carbon esebenzayo + indlela yokuminza ephansi yokushisa, okuwuhlelo lomshuwalense olunezinyathelo ezimbili noluphindwe kabili. Okokuqala, ama-hydrocarbon asindayo njenge-benzene nama-hydrocarbon aromatic amuncwa nge-activated carbon ekushiseni kwegumbi, bese izingxenye ezisindayo ngaphezu kwe-propane ziminyaniswe ku--65 ℃, okungeke nje kususe izingxenye ezisindayo kugesi yokudla, kodwa futhi kuhlukanise izingxenye ezisindayo ukuze kutholakale ama-hydrocarbon axubile njengomkhiqizo ophumayo.
Impendulo yokuphelelwa amanzi emzimbeni
Okuqukethwe kwamanzi kugesi yemvelo kuncike kakhulu ekushiseni nasekucindezelweni. Ukushintsha kwezinye izingxenye zegesi yokudla ngeke kube nomthelela omkhulu kokuqukethwe kwamanzi. Isibonelelo sokuklama sokususa amanzi sanele ukubhekana naso.
Impendulo yesistimu yoketshezi ezinguqukweni zezingxenye
Ukushintsha kokwakheka kwegesi yokuphakelayo kuzoholela ekushintsheni komugqa wokushisa wegesi yemvelo oncibilikayo. Ngokulungisa kahle isilinganiso se-mixed refrigerant (MR), ushintsho lokwakheka kwegesi yokuphakelayo lungashintshwa lube ububanzi obukhulu.
