Ingozi yokuqhuma ngo-2005 kwindawo yokucocisa iBP eTexas, eMelika

Ukuqhuma kwenzeke ngexesha lokugcinwa kwesixhobo sokutshintsha ubushushu kwiyunithi ye-isomerization yefektri yokucoca i-BP eTexas, nto leyo eyabangela ukufa kwabantu abali-15 kunye nokulimala kwabantu abali-170, kunye nelahleko enkulu kwezoqoqosho. Le ngozi yaba yimeko eqhelekileyo yokusilela kokwahlulwa kwamandla kwicandelo lezemizi-mveliso kwihlabathi liphela.
Inkqubo yengozi kunye nesizathu esithe ngqo
Ngexesha lokugcinwa kombhobho wokutya wesixhobo sokutshintsha ubushushu kwisityalo, ipleyiti engabonakaliyo yokwahlulwa okusebenzayo ayizange ifakwe njengoko kufuneka, kwaye kuphela ivalvu ephezulu yayivaliwe. Ngenxa yokuvuza kwangaphakathi kwevalvu, izinto zehydrocarbon zaqhubeka nokuvuza, kwaye ekugqibeleni kwenzeka ukuqhuma ngenxa yokuba kukho umthombo womlilo. Ingxaki ephambili yengozi yayikukwahlulwa kwamandla okungaphelelanga, njengoko ukuthembela kuphela ekuhlukanisweni kwevalvu kwakungenakuyisusa ingozi yokuvuza kwezinto. Ingozi efihlakeleyo yokuvuza kwangaphakathi kwevalvu ayizange ichongwe, kwaye amandla eekhemikhali (uxinzelelo) kwipayipi awazange ahlukaniswe ngokupheleleyo kwaye akhululwe, nto leyo ekhokelele ekukhutshweni kwamandla okungalindelekanga kwaye kubangele intlekele.
Unobangela onzulu wengozi
Ukuphunyezwa okunganelanga kwemigangatho yokwahlulwa kwamandla: Eli shishini alizange lilandele ngokungqongqo umgangatho wenkqubo yokwahlulwa kweenkqubo "zokwahlulwa kweevalvu ezimbini + iplati engaboniyo", nto leyo eyanciphisa iimfuno zokwahlulwa kwamandla kwimisebenzi yemibhobho enobungozi obukhulu, kwaye laxhomekeka kakhulu kwivalvu enye yokwahlulwa.
Ukungonelanga kokwazi ukuchonga umngcipheko:Iingozi ezinokubakho ezifana nokuvuza kwangaphakathi kwevalvu azizange ziqwalaselwe ngokupheleleyo, uvavanyo lwempembelelo yokwahlulwa kwemithombo yamandla belunganelanga, kwaye bekungekho ndlela zokuqinisekisa ezisebenzayo.
Iziphene kwinkqubo yolawulo lokhuseleko:Eli shishini lalibeka phambili imveliso ngaphezu kokhuseleko, lalingenalo utyalo-mali olupheleleyo lokhuseleko, kwaye lalingenalo uqeqesho lokhuseleko kubasebenzi, nto leyo eyabangela ukuba abasebenzi bangayilandeli ngokungqongqo imigaqo yokwahlulwa kwamandla.
Ukungaphumeleli kweendlela zokujonga nokuhlola:Akukho ndlela ikhethekileyo yokuhlaziya ukusetyenziswa kwamanyathelo okwahlula amandla asekwe, nto leyo eyenza kube nzima ukubona nokulungisa ukwaphulwa kwemigaqo kwinkqubo yokwahlula amandla.
Izifundo zeengozi kunye namanyathelo okulungisa
Ukuphucula imigangatho yokwahlulwa kwamandla:Kwimisebenzi yemibhobho yenkqubo enomngcipheko ophezulu, kufuneka kusetyenziswe amanyathelo amaninzi okwahlulahlula abizwa ngokuba yi-"double valve isolation + intermediate release + blind plate isolation", kwaye ukuvala ivalvu yodwa njengendlela yokwahlulahlula amandla akuvumelekanga ngokungqongqo; ii-blind plates kufuneka zibhalwe kwaye zilawulwe, kwaye kufuneka kusekwe i-blind plate ledger ukuqinisekisa ukuba inkqubo yokufakela nokususa ii-blind plates iyalandeleka.
Phucula inkqubo yokuqinisekisa isiphumo sokuzahlula:Sebenzisa uvavanyo loxinzelelo, ukufunyanwa kwegesi, njl.njl., ukuqinisekisa imeko ye-zero-energy yombhobho ohlukanisiweyo ukuqinisekisa ukuba akukho mngcipheko wokuvuza kwezinto.
Qinisa ulwakhiwo lwenkcubeko yokhuseleko: Misela ingcamango ethi “ukhuseleko kuqala”, yandisa utyalo-mali lokhuseleko, yomeleza uqeqesho lokhuseleko lwabasebenzi, kwaye yomeleza ukuqonda kwabasebenzi ngokubaluleka kokuzahlula amandla kunye nokukwazi kwabo ukulandela imigaqo ngokungqongqo.
Misela indlela ezimeleyo yokubeka esweni nokuhlaziya: Misela isebe elizinikeleyo lokubeka esweni ukhuseleko ukuze liqhube ukubekwa esweni ngokupheleleyo koqulunqo, ukuphunyezwa, kunye nokuqinisekiswa kwamanyathelo okwahlula amandla, lenze uhlolo lokhuseleko rhoqo, kwaye lichonge kwaye lilungise iingozi zokhuseleko ngokukhawuleza.
