Iimfuno ezizodwa ze-LNG Seksgenic
Umhla: APR 23, 2020
Irhasi yendalo yamkelwa njengomoya ococekileyo, onobuhlobo obukhuselekileyo kunye nomthombo wamandla aphezulu. Umthamo wegesi yendalo etyhutyhakeleyo incitshisiwe ngamaxesha angama-600, ezizisa izibonelelo ezinkulu zokugcina. I-thamossicIitanki zokugcina i-Crygeniczisetyenziselwa ukugcina igesi yendalo etyhutywe.Iitanki ze-lngYiba nezi mfuno zilandelayo zilandelayo.
1. Ukuxhathisa kobushushu obuphantsi; Indawo yokubila ye-LNG phantsi koxinzelelo oluqhelekileyo yi -160 ℃. Khetha ubushushu obuphantsi kunye nendlela yokufumana uxinzelelo oluqhelekileyo lokunciphisa ubushushu begesi yendalo engezantsi kwendawo yokubila, ukuze uxinzelelo olusebenzayo lwetanki lokugcina ubushushu liphezulu kunoxinzelelo oluqhelekileyo. Xa kuthelekiswa noxinzelelo oluphezulu kunye nendlela yokugcina amaqondo obushushu, inokunciphisa kakhulu ubukhulu bodonga lwetanki kunye nokuphucula ukusebenza kwezokhuseleko; Ke ngoko, itanki yokugcina amaqondo obushushu e-Atmospheric iyacelwa ukuba ibe nokuphiliswa kobushushu obucacileyo kunye nokusebenza okugqwesileyo.
2. Iimfuno zokhuseleko eziphezulu; Ngenxa yolwelo olugcinwe kwitanki, kanye ukuba ingozi yenzekile kwitanki yokugcina, ulwelo olunefriji luza kuphazamisa kakhulu, kwaye isixa se-vapority simalunga namaxesha angama-300 esiya kuthi ga kwi-Air studs esiya kubeka ngokuzenzekelayo kwimozulu. Ke ngoko, i-API, i-Bs kunye nezinye iinkcukacha zifuna itanki yokugcina i-Crygenic yokwamkela isakhiwo se-mbinidonga, sisebenzisa umxholo wokuvalwa. Xa umaleko wokuqala wetanki, umaleko wesibini wetanki unokuyithintela ngokupheleleyo irhasi yolwelo kwaye ikhuselekile kwirhasi.
3. Izixhobo ezizodwa; Udonga lwetanki lwangaphakathi lwetanki yokugcina i-LNG ifuna ukumelana nobushushu obuphantsi, i-9NI yentsimbi okanye i-Aluminium Alfy kunye nezinye izinto zisetyenzisiwe, kwaye udonga olungaphandle lwetanki luqinisekisiwe.
4. I-thenomenon yokutyibilika; I-tymbling phenomenon ibhekisa kwi-phenomenon apho iingqimba ezimbini ze-LNG kunye nokuxinana kobushushu obuphangazekileyo kukhawuleziswa kwitanki yokugcina amanzi asezantsi, kwaye isixa esikhulu se-distives senzeka ngoko nangoko. Ngeli xesha, isixa se-vaporing ye-LNG kwitanki liyi-10 ukuya kuma-50 amaxesha okutshona kwendalo, okuya kubangela uxinzelelo lomoya kwitanki yokugcina ukuya kunyuka ngokukhawuleza, kubangela ukuba itanki yogcino ibonakale inqabile. Ukuba ayikhutshwa kwivalve yokhuseleko ngexesha, inokubangela ukonakala koomatshini kwitanki yokugcina, kubangela ilahleko yoqoqosho kunye nongcoliseko lwendalo. Ingcambu yento engundoqo kukuba ukuxinana kolwelo kwetanki yogcino kwitanki yogcino kwahlukile, kwaye ubukho bezingcungcutheka ziyimpembelelo ebalulekileyo ngexesha kunye nenqanaba lokuxhumala.
