Njengomgangatho ophezulu, osebenzayo, kunye namandla acocekileyo afanelekileyo kunye nemathiriyeli ekrwada yeekhemikhali, igesi yendalo inamandla amakhulu okusebenza. Phakathi kwabo, i-liquefied natural gas (LNG), enezinga eliphezulu lokuthengisa, sele iqalile ukutsala ingqalelo njengesongezelelo kwimithombo yegesi yendabuko.
Ekubeni iipayipi ze-LNG ziyipayipi eziqhelekileyo zokuthutha ezinobushushu obuphantsi, i-LNG ethuthwa ngepayipi ngokubanzi ikwimeko yolwelo oluphantsi. Xa ubushushu bangaphandle bungena, buya kuba ngumphunga ngokulula, nto leyo ebangela ukuba ukuhamba kolwelo lwesigaba esinye kutshintshe kube kukuhamba kwegesi-ulwelo olunezigaba ezimbini, okanye nokuba kukutshixwa kwegesi, nto leyo ebangela ukwanda koxinzelelo kunye nokwehla kwesantya sokuhamba kwiindawo zepayipi zasekuhlaleni, nto leyo echaphazela kakhulu ukuthuthwa okuqhelekileyo kwe-LNG. Ke ngoko, ukufudunyezwa kwe-LNG kufuneka kulawulwe ngokungqongqo. Nangona kunjalo, ukufudunyezwa kwepayipi ye-LNG kunokuthintela ukungena kobushushu bangaphandle kunye nokufudunyezwa kwe-LNG, kwaye ukusebenza kwayo kuxhomekeke kakhulu kumgangatho wokufudunyezwa kwepayipi ye-LNG. Ke ngoko, iipayipi ze-LNG kufuneka zamkele amanyathelo okufudunyezwa kobushushu , kwaye umgangatho wazo awuyi kuchaphazela kuphela ukusebenza kakuhle kokuthuthwa kwe-LNG, kodwa unokuba nempembelelo ebalulekileyo ekusebenzeni okuqhelekileyo kwenkqubo yonke.
Iintlobo zokugquma kwemibhobho ye-LNG
I-vacuum insulation: Umgaqo-siseko kukwenza ulwakhiwo lwe-insulation kwi-interlayer etywiniweyo, kwaye indawo yangaphakathi ikhutshelwa kwinqanaba elithile le-vacuum ukunciphisa ukuhanjiswa kobushushu. Kwinkqubo ye-LNG yasekhaya, inexesha elide lokusetyenziswa, isiphumo esicacileyo se-thermal insulation kunye nokulahlekelwa kwamandla amancinci. Nangona kunjalo, ngenxa yexabiso eliphezulu kunye nexesha elide lokuvelisa, lisetyenziswa kakhulu kwiiprojekthi eziphambili kwaye ayikwazi ukusetyenziswa kwinqanaba elikhulu.
Ukufakwa kwe-stacking: Ukufakwa kwe-stacking kuyindlela yendabuko yokugquma, oko kukuthi, izinto zokufakelwa kwe-porous zifakwe ngaphandle kombhobho, kwaye i-insulation iphunyeziwe ngenxa yokuba iiseli zizaliswe ngumoya oqhelekileyo woxinzelelo (okanye ezinye iigesi). Impembelelo yokufakelwa kwe-thermal ingaphantsi kancinane kune-vacuum insulation, kodwa inesakhiwo esilula, ixabiso eliphantsi, kunye nokusebenza kakuhle kunye nokugcinwa. Okwangoku, imibhobho ye-LNG yasekhaya isebenzisa le ndlela yokufakelwa kwemibhobho.
Kwimakethi yangoku, izinto ezikhoyo zokugquma ezipakishweyo zisebenzisa i-polyurethane kunye nemathiriyeli yeglasi egwebu ngokwamaqondo obushushu e-LNG ahlukeneyo. Xa kuthelekiswa nezinto zokufakelwa kwe-thermal eziqhelekileyo ezifana ne-polyurethane kunye neglasi ye-foam, i-melamine foam ineenzuzo ezininzi. I-Melamine foam inoluhlu olubanzi lokuchasana kwemozulu (minus 196 degrees Celsius ukuya kuma-200 degrees Celsius), igcina isakhiwo esizinzileyo somzimba kunye neekhemikhali phantsi kweemeko eziphezulu kunye nezisezantsi zokushisa, kwaye inika i-conductivity egqwesileyo ye-thermal (i-coefficient conductivity ye-thermal, i-0.032 W / (m * K)) kunye nokusebenza kwesandi sokufunxa (0.95NRC), yenza i-insulation impahla ekhuselekileyo, i-LNG, i-insulation yendalo kunye ne-insulation lightweight.
Kuyilo lobunjineli bezikhululo zezityalo ze-LNG, imeko yokwenyani yeprojekthi kufuneka ihlalutywe ngokuthe ngqo, kwaye i-thermal insulation efanelekileyo kunye nezixhobo ezibandayo kufuneka zikhethwe kwaye zisetyenziswe. Amagqabantshintshi ayo aquka:
- Ubuncinci beqondo lokushisa elikhuselekileyo lokusetyenziswa kwezinto ezibandayo kufuneka libe ngaphantsi kweqondo lokushisa eliphakathi ngexesha lokusebenza okuqhelekileyo;
- Umsebenzi wokukhusela umlilo wezinto ezibandayo zokugquma kufuneka uhlangabezane neemfuno zemigangatho yelizwe yangoku;
- Ukubeka phambili ukusetyenziswa kwezixhobo zokugquma ezibandayo kunye nokumelana okugqwesileyo komphunga wamanzi ukuqinisekisa ukuzinza kwexesha elide lokusebenza kwezinto;
- Izinto ezibandayo zokugquma kufuneka zibe nokusebenza kakuhle kokusika okanye ukusika ukusika, ukwakhiwa okulula, kunye nobunzima bofakelo olulula kwisiza;
- Ukunika ingqwalaselo ephambili kwimathiriyeli okanye iimveliso ezineenzuzo eziphezulu zezoqoqosho;
- Nciphisa ubungakanani bomsebenzi wolondolozo lwemihla ngemihla emva kokuba inkqubo yokupholisa ifakwe kwimveliso nokuphucula ukusetyenziswa kwakhona kwezinto.
Ngokusekelwe kwiimfuno ezingentla, i-melamine foam ingasetyenziswa njengesixhobo sokukhusela ubushushu kunye nezinto zokugcina ubushushu kwiipayipi ze-LNG, kwaye i-melamine foam idlala indima ebalulekileyo ekukhuseleni ubushushu kunye nokugcinwa kobushushu kwiipayipi ze-LNG. I-Melamine foam sisixhobo seplastiki se-elastomer esiguquguqukayo esinesakhiwo senethiwekhi esinemilinganiselo emithathu. Isagcina isakhiwo esipheleleyo somzimba kunye neekhemikhali kwiqondo lobushushu elingaphantsi kwe-196 degrees Celsius, ngoko ke isenokuqhuba kakuhle kobushushu kumaqondo obushushu aphantsi kwaye ithintela ukujikeleza kweendawo zangaphakathi nangaphandle. Ukuqhuba ubushushu kunye nemitha, ukumelana okuhle kakhulu nomlilo (B1, UL94 V0 kunye ne-HL-1) kunye neempawu zokukhusela (azivelisi naluphi na uhlobo lwe-static kunye ne-antistatic), ukumelana ne-asidi kunye ne-alkali, ukumelana nokugqwala, ukumelana nokwaluphala, ubunzima obulula kunye nokuguquguquka kobushushu obuphantsi, njl.njl., kwaye ngenxa yokuba i-melamine resin foam yinto ethambileyo kodwa engenafayibha, ayinalo naluphi na uthuli, ayina-halogenated kwaye ayina-hydrocarbons, ayinamalangabi kwaye/okanye ayinazo iintsimbi ezinzima ezinetyhefu, ifanelekile ngakumbi kwiindawo ezineemfuno eziphezulu kakhulu ezinobuhlobo nokusingqongileyo, indawo yokugcina ebandayo (isityalo sokucubungula amayeza, isityalo sokucubungula iziqhamo nemifuno, isityalo sokucubungula ukutya, isityalo sokucubungula inyama kunye nomzi-mveliso weziselo ezibandayo) ukuthintela ukubanda (ukuthintela ukubanda kunye ne-acoustic), ukuthintela ukubanda okufrijiweyo/okufrijiweyo (ukuthintela ukubanda kunye ne-acoustic), ukuthintela ukubanda kwetanki yokugcina ulwelo lwe-LNG (ukuthintela ukubanda kunye ne-acoustic), isithuthi sokuthutha esinyibilikisiweyo se-LNG okanye ukuthintela ukubanda kunye ne-thermal (ukuthintela ukubanda kunye ne-acoustic).
