Njengoko umthamo wentengiso yeemveliso ze-LNG utshintsha ngokwemeko yemarike, imveliso ye-LNG kufuneka ihambelane notshintsho lwemarike. Ke ngoko, kufuneka kubekho iimfuno eziphezulu zokuqina komthwalo wemveliso kunye nokugcinwa kwezityalo ze-LNG nge-LNG.
Ulawulo lomthwalo wemveliso ye-LNG
Ulawulo lwe-Mr compressor
I-MR compressor yi-centrifugal compressor. Umthwalo wayo ungalungiswa rhoqo phakathi kwe-50 ~ 100% ngokulungelelanisa isixhobo sokugquma ivalvu yokungena komoya kunye nevalvu yokubuyisela ye-compressor.
Ulawulo lomthwalo wenkqubo yonyango lwangaphambi konyango
Umthwalo woyilo lweyunithi yegesi yokususa iasidi akufuneki ube ngaphantsi kwe-100%. Ngokwesiseko sokulawula uxinzelelo, isixhobo senkqubo yonyango lwangaphambi konyango sinokuhlengahlengiswa ngokuqhubekayo ngaphakathi koluhlu lomthwalo oluyi-50 ~ 110% kwaye sihlangabezane nomgangatho wonyango lwangaphambi konyango kunye nokucoca.
Uluhlu lolawulo lomthwalo webhokisi ebandayo enyibilikisiweyo
Umthwalo woyilo lwebhokisi ebandayo enyibilikisiweyo akufuneki ube ngaphantsi kwe-100%. Xa umthwalo wesixhobo utshintsha ukusuka kwi-50% ukuya kwi-100%, isixhobo sokutshintshiselana nobushushu bepleyiti kunye neevalvu ezikwibhokisi ebandayo zinokusebenza ngokuqhelekileyo kwaye zihlangabezane ngokupheleleyo neemeko zokusebenza zomthwalo oguquguqukayo.
Ngamafutshane, ukuguquguquka kokusebenza kwesixhobo siphela yi-50% ~ 100%. Abasebenzisi banokuyilungisa umthwalo wesixhobo ngaphakathi kolu luhlu ngokwemeko yokuthengisa yemveliso ukuphucula uqoqosho lokusebenza.
Ukulungiswa komthamo wokugcina itanki yokugcina i-LNG
Ngokwemveliso ye-LNG, umthamo wetanki yokugcina esiwunikezelayo ngumthamo we-LNG weentsuku ezilishumi, kwaye umthamo wokugcina wetanki yokugcina ungasetyenziselwa ukuthintela utshintsho lwentengiso.
Utshintsho lwesakhiwo segesi yokutya
Utshintsho kwimilo yegesi yokutya luya kuzisa imingeni ekunyangweni kwangaphambi kokusetyenziswa kwayo kunye nolwelo.
Impendulo yenkqubo yonyango lwangaphambi kokusetyenziswa kwegesi yokuphakelwa komoya kutshintsho lwecandelo
Impendulo yokususa icarbonization
Ngokwesiqulatho sekhabhoni diokside esikhoyo, sisebenzisa indlela ye-MDEA amine ukususa ikhabhoni diokside nokunyusa uyilo lwekhabhoni diokside ukuya kwi-3%. Inani elikhulu lamava obunjineli obusebenzayo libonakalise ukuba olu yilo lunokuziqhelanisa notshintsho lwesiqulatho sekhabhoni diokside kwaye lususe ikhabhoni diokside ukuya kwinqanaba le-50ppm.
Ukususwa kwe-hydrocarbon enzima
Iihydrocarbon ezinzima kwigesi yendalo ikakhulu zii-neopentane, i-benzene, iihydrocarbon ezinuka kamnandi kunye nezinto ezingaphezulu kwe-hexane ezibangela umonakalo kwinkqubo ye-cryogenic yebhokisi ebandayo. Inkqubo yokususa esiyisebenzisayo yindlela yokufunxa i-carbon esebenzayo + indlela yokufunxa i-low-temperature, eyinkqubo yomshuwalense enamanyathelo amabini kunye nephindwe kabini. Okokuqala, iihydrocarbon ezinzima ezifana ne-benzene kunye neehydrocarbon ezinuka kamnandi zifunxwa nge-activated carbon kubushushu begumbi, kwaye emva koko izinto ezinzima ezingaphezulu kwepropane zifunxwa kwi--65 ℃, ezingenakususa kuphela izinto ezinzima kwigesi yokutya, kodwa zahlule nezinto ezinzima ukuze kufumaneke iihydrocarbon ezixutyiweyo njengemveliso ephumayo.
Impendulo yokuphelelwa ngamanzi emzimbeni
Umthamo wamanzi kwigesi yendalo uxhomekeke kakhulu kubushushu kunye noxinzelelo. Utshintsho kwezinye izinto zegesi yokutya aluyi kuba nefuthe elikhulu kumthamo wamanzi. Isibonelelo soyilo lokukhupha amanzi sanele ukumelana naso.
Impendulo yenkqubo yokunyibilikisa ulwelo kwiinguqu zecandelo
Utshintsho lokwakheka kwegesi yokutya luya kukhokelela kutshintsho lobushushu begesi yendalo enyibilikayo. Ngokulungisa ngokufanelekileyo umlinganiselo we-mixed refrigerant (MR), utshintsho lokwakheka kwegesi yokutya lunokulungiswa lube kuluhlu olukhulu.
