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.
Igesi yemvelo encibilikisiwe (i-LNG), ingxenye yayo eyinhloko eyi-methane, ibhekwa njengamandla ahlanzekile kakhulu emhlabeni. Ayinambala, ayinambitheki, ayinabuthi futhi ayiboli, umthamo wayo cishe u-1/625 wevolumu yenani elifanayo legesi yemvelo encibilikisiwe, kanti isisindo segesi yemvelo encibilikisiwe singama-45% kuphela wamanzi emzimbeni ofanayo.
Inqubo yokukhiqiza iwukuhlanza igesi yemvelo ekhiqizwa ensimini yegesi, bese iyithutha ngomkhumbi we-LNG ngemuva kochungechunge lokuncibilika kokushisa okuphansi kakhulu. Ukushiswa kwegesi yemvelo encibilikisiwe akungcolisi umoya kakhulu futhi kukhipha ukushisa okuningi, ngakho-ke igesi yemvelo encibilikisiwe ingamandla athuthukile.
