Ingozi yokuqhuma ngo-2005 efektri yokuhlanza i-BP eTexas, e-USA

Ukuqhuma kwenzeke ngesikhathi kulungiswa umshini wokushintshanisa ukushisa eyunithi ye-isomerization yefektri yokuhlanza i-BP eTexas, okwaholela ekufeni kwabantu abangu-15 kanye nokulimala okungu-170, kanye nokulahlekelwa okukhulu kwezomnotho. Le ngozi yaba yicala elivamile lokwehluleka kokuhlukanisa amandla emkhakheni wezimboni womhlaba wonke.
Inqubo yengozi kanye nembangela eqondile
Ngesikhathi kugcinwa ipayipi lokuphakelwa kwe-heat exchanger esitshalweni, ipuleti eliyimpumputhe lokuhlukanisa okusebenzayo alifakwanga njengoba kudingeka, futhi i-valve ephezulu kuphela eyayivaliwe. Ngenxa yokuvuza kwangaphakathi kwe-valve, izinto ze-hydrocarbon zaqhubeka nokuvuza, futhi ekugcineni kwenzeka ukuqhuma ngenxa yokuba khona komthombo womlilo. Inkinga eyinhloko yengozi kwakuwukuhlukaniswa kwamandla okungaphelele, njengoba ukuthembela kuphela ekuhlukanisweni kwe-valve kwakungeke kuqede ingozi yokuvuza kwezinto. Ingozi efihliwe yokuvuza kwangaphakathi kwe-valve ayizange itholakale, futhi amandla amakhemikhali (ingcindezi) epayipini awazange ahlukaniswe ngokuphelele futhi akhishwe, okwaholela ekukhululweni kwamandla okungalindelekile futhi kwabangela inhlekelele.
Imbangela ejulile yengozi
Ukungasebenzisi kahle amazinga okuhlukaniswa kwamandla: Ibhizinisi alizange lilandele ngokuqinile indinganiso yokuhlukaniswa kwesistimu yenqubo ethi “double valve isolation + blind plate”, lehlisa izidingo zokuhlukaniswa kwamandla zokusebenza kwamapayipi anengozi enkulu, futhi lathembela kakhulu ekuhlukanisweni kwevalvu eyodwa.
Ukungakwazi ukuhlonza ubungozi okwanele:Izingozi ezingaba khona njengokuvuza kwangaphakathi kwe-valve azizange zicatshangelwe ngokugcwele, ukuhlolwa komphumela wokuhlukaniswa kwemithombo yamandla akwanele, futhi azikho izindlela zokuqinisekisa ezisebenzayo.
Amaphutha ohlelweni lokuphatha ukuphepha:Ibhizinisi lalibeka phambili ukukhiqizwa kunokuphepha, lalingenalo utshalomali oluphelele lokuphepha, kanye nokuqeqeshwa okwanele kokuphepha kwabasebenzi, okwaholela ekutheni abasebenzi bangazilandeli ngokuqinile izindinganiso zokuhlukanisa amandla.
Ukwehluleka kwezindlela zokuqapha nokubuyekeza:Akukho ndlela ekhethekile yokubuyekeza ukusetshenziswa kwezinyathelo zokuhlukanisa amandla eyasungulwa, okwenza kube nzima ukubona nokulungisa ukwephulwa kwemithetho ngokushesha enqubweni yokuhlukanisa.
Izifundo zezingozi kanye nezinyathelo zokulungisa
Thuthukisa amazinga okuhlukaniswa kwamandla:Ukuze kusebenze ipayipi lenqubo enobungozi obukhulu, kudingeka ukuqaliswa okuphoqelekile kwezinyathelo eziningi zokuhlukanisa “i-double valve isolation + intermediate release + blind plate isolation”, futhi ukuvala i-valve yodwa njengendlela yokuhlukanisa amandla akuvunyelwe ngokuphelele; ama-blind plate kufanele abhalwe izinombolo futhi aphathwe, futhi kufanele kusungulwe i-blind plate ledger ukuqinisekisa ukuthi inqubo yokufaka nokususa ama-blind plate iyalandeleka.
Thuthukisa inqubo yokuqinisekisa umphumela wokuhlukaniswa:Sebenzisa ukuhlolwa kwengcindezi, ukutholwa kwegesi, njll., ukuqinisekisa isimo sepayipi elihlukanisiwe esingenawo amandla ukuqinisekisa ukuthi akukho bungozi bokuvuza kwezinto.
Qinisa ukwakhiwa kwesiko lokuphepha: Misa umqondo wokuthi “ukuphepha kuqala”, wandise ukutshalwa kwezimali kokuphepha, uqinise ukuqeqeshwa kokuphepha kwabasebenzi, futhi uthuthukise ukuqwashisa kwabasebenzi ngokubaluleka kokuhlukaniswa kwamandla kanye nekhono labo lokulandela imigomo ngokuqinile.
Misa indlela yokuqapha nokubuyekeza ezimele: Misa umnyango ozinikele wokuqapha ukuphepha ukuze uqhube ukuqapha okugcwele kokwakhiwa, ukusetshenziswa, kanye nokuqinisekiswa kwezinyathelo zokuhlukanisa amandla, wenze ukuhlolwa kokuphepha njalo, futhi ukhombe futhi ulungise izingozi zokuphepha ngokushesha.
