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.
Igesi yendalo enyibilikisiweyo (i-LNG), eyona nto iphambili yi-methane, ibonwa njengamandla acocekileyo e-fossil emhlabeni. Ayinambala, ayinancasa, ayinatyhefu kwaye ayibolisi, umthamo wayo umalunga ne-1/625 yomthamo wegesi yendalo efanayo, kwaye ubunzima begesi yendalo enyibilikisiweyo bumalunga ne-45% yamanzi emzimbeni omnye.
Inkqubo yokuvelisa kukucoca igesi yendalo eveliswa kwicandelo legesi, kwaye ithuthwe ngenqanawa ye-LNG emva kothotho lwe-liquefaction yobushushu obuphantsi kakhulu. Ukutsha kwegesi yendalo enyibilikisiweyo akunangcoliseko lomoya kwaye kukhupha ubushushu obuninzi, ngoko ke igesi yendalo enyibilikisiweyo ngamandla aphucukileyo.
