Itanki yokugcina i-ammonia engamanzi
I-ammonia engamanzi ifakiwe kuluhlu lweekhemikhali eziyingozi ngenxa yeempawu zayo ezivuthayo, eziqhumayo, nezinobungozi. Ngokwe-“Ukuchongwa kweMithombo Eyingozi Emikhulu yeeKhemikhali Eziyingozi” (GB18218-2009), umthamo wokugcina i-ammonia obalulekileyo ongaphezulu kweetoni ezili-10*** uyinxalenye enkulu yengozi. Zonke iitanki zokugcina i-ammonia engamanzi zihlulwe njengeentlobo ezintathu zemithambo yoxinzelelo. Ngoku hlalutya iimpawu ezinobungozi kunye neengozi ngexesha lokuveliswa nokusebenza kwetanki yokugcina i-ammonia engamanzi, kwaye ucebise amanyathelo okuthintela kunye nawongxamiseko okuthintela iingozi.
Uhlalutyo lweengozi zetanki yokugcina i-ammonia engamanzi ngexesha lokusebenza
Iimpawu eziyingozi ze-ammonia
I-Ammonia yigesi engenambala necacileyo enevumba elimnandi, elinyibilikiswa lula libe yi-ammonia engamanzi. I-Ammonia ilula kunomoya kwaye inyibilika lula emanzini. Ekubeni i-ammonia engamanzi itshintshatshintsha lula ibe yigesi ye-ammonia, xa i-ammonia nomoya zixutywe ngokulinganayo, zinokuvezwa kumlilo ovulekileyo, ubuninzi be-15-27%, emoyeni ojikeleze indawo yokusebenzela ***** *Uxinzelelo oluvumelekileyo yi-30mg/m3. Igesi ye-ammonia evuzayo inokubangela ityhefu, ukurhawuzelelwa emehlweni, kwi-mucosa yemiphunga, okanye kulusu, kwaye kukho ingozi yokutsha okubandayo ngamakhemikhali.
Uhlalutyo lomngcipheko wenkqubo yemveliso kunye nokusebenza
1. Ulawulo lwenqanaba le-ammonia
Ukuba izinga lokukhululwa kwe-ammonia likhawuleza kakhulu, ulawulo lokusebenza kwenqanaba lolwelo luphantsi kakhulu, okanye ezinye iingxaki zolawulo lwezixhobo, njl.njl., igesi yokwenziwa enoxinzelelo oluphezulu iya kuphuma iye kwitanki yokugcina i-ammonia engamanzi, nto leyo ebangela uxinzelelo olugqithisileyo kwitanki yokugcina kunye nokuvuza okukhulu kwe-ammonia, nto leyo eyingozi kakhulu. Ulawulo lwenqanaba le-ammonia lubaluleke kakhulu.
2. Umthamo wokugcina
Umthamo wokugcina wetanki yokugcina i-ammonia engamanzi udlula i-85% yomthamo wetanki yokugcina, kwaye uxinzelelo ludlula uluhlu lwesalathisi solawulo okanye umsebenzi wenziwa kwitanki eguqulweyo ye-ammonia engamanzi. Ukuba iinkqubo kunye namanyathelo azilandelwanga ngokungqongqo kwimigaqo yokusebenza, kuya kwenzeka ukuvuza koxinzelelo olugqithisileyo***** *ingozi.
3. Ukuzaliswa kwe-ammonia engamanzi
Xa i-ammonia engamanzi izaliswe, ukuzaliswa kakhulu akwenziwa ngokwemigaqo, kwaye ukuqhushumba kombhobho wokuzalisa kuya kubangela ukuvuza kunye neengozi zokutyhefa.
Uhlalutyo lweengozi zezixhobo kunye nezibonelelo
1. Uyilo, ukuhlolwa, kunye nokugcinwa kweetanki zokugcina i-ammonia engamanzi azikho okanye azikho endaweni yazo, kwaye izixhobo zokhuseleko ezifana neegeyiji zamanqanaba, iigeyiji zoxinzelelo, kunye neevalvu zokhuseleko zinesiphene okanye zifihliwe, nto leyo enokubangela iingozi zokuvuza kwetanki.
2. Ehlotyeni okanye xa ubushushu buphezulu, itanki yokugcina i-ammonia engamanzi ayinazo ii-awnings, amanzi okupholisa aqinileyo kunye nezinye izinto zokuthintela njengoko kufuneka, nto leyo eya kubangela ukuvuza okugqithisileyo kwetanki yokugcina.
3. Ukonakala okanye ukungaphumeleli kokhuseleko lombane kunye nezixhobo ezichasene nokuma komhlaba okanye ukumiswa komhlaba kunokubangela ukothuka kombane kwitanki yokugcina.
4. Ukungaphumeleli kwee-alamu zenkqubo yemveliso, ii-interlocks, uncedo olungxamisekileyo kuxinzelelo, ii-alamu zegesi ezitshayo nezinobungozi kunye nezinye izixhobo kuya kubangela iingozi zokuvuza okugqithisileyo okanye ukwandiswa kwetanki yokugcina.
Amanyathelo okuthintela iingozi
Amanyathelo okuthintela ukusebenza kwenkqubo yemveliso
1. Sebenzisa ngokungqongqo iinkqubo zokusebenza
Nika ingqalelo kwindlela esebenza ngayo i-ammonia ekhupha i-ammonia kwiipali zokwenziwa, lawula inqanaba lolwelo lokwahlulwa kwe-cold cross kunye ne-ammonia, gcina inqanaba lolwelo lizinzile ngaphakathi koluhlu lwe-1/3 ukuya kwi-2/3, kwaye uthintele inqanaba lolwelo ukuba liphantsi kakhulu okanye liphezulu kakhulu.
2. Lawula ngokungqongqo uxinzelelo lwetanki yokugcina i-ammonia elulwelo
Umthamo wokugcina we-ammonia engamanzi akufuneki udlule kwi-85% yomthamo wetanki yokugcina. Ngexesha lokuveliswa okuqhelekileyo, itanki yokugcina i-ammonia engamanzi kufuneka ilawulwe kwinqanaba eliphantsi, ngokubanzi ngaphakathi kwe-30% yomthamo wokuzalisa okhuselekileyo, ukuze kuthintelwe ukugcinwa kwe-ammonia ngenxa yobushushu obuphakathi. Ukwanda kokwanda kunye noxinzelelo kuya kubangela uxinzelelo olugqithisileyo kwitanki yokugcina.
3. Amanyathelo okhuseleko xa kuzaliswa i-ammonia engamanzi
Abasebenzi abafaka i-ammonia bafanele baphumelele imfundo noqeqesho lokhuseleko lobuchwephesha ngaphambi kokuba bangene kwizikhundla zabo. Bafanele baqhelane nokusebenza, iimpawu, iindlela zokusebenza, ulwakhiwo lwezixhobo, umgaqo wokusebenza, iimpawu eziyingozi ze-ammonia engamanzi kunye namanyathelo onyango olungxamisekileyo.
Ngaphambi kokuzalisa, kufuneka kuqinisekiswe ukuba iziqinisekiso ezinje ngokuqinisekiswa kovavanyo lwetanki, ilayisenisi yokusebenzisa itanki, ilayisenisi yokuqhuba, isiqinisekiso sokupheleka, kunye nemvume yokuthutha. Izixhobo zokhuseleko kufuneka ziphelele kwaye zibe novelwano, kwaye uhlolo kufuneka luqinisekiswe; uxinzelelo olukwitanki ngaphambi kokuzalisa kufuneka lube phantsi. Ngaphantsi kwe-0.05 MPa; ukusebenza kombhobho woqhagamshelo lwe-ammonia kufuneka kuhlolwe.
Abasebenzi abafaka i-ammonia kufuneka balandele ngokungqongqo iinkqubo zokusebenza kwetanki yokugcina i-ammonia engamanzi, kwaye banikele ingqalelo kumthamo wokuzalisa ongadluli kwi-85% yomthamo wetanki yokugcina xa begcwalisa.
Abasebenzi abafaka i-ammonia kufuneka banxibe iimaski zegesi kunye neeglavu zokukhusela; indawo kufuneka ixhotyiswe ngezixhobo zokulwa nomlilo kunye nezokukhusela igesi; ngexesha lokuzalisa, akufuneki baphume kwindawo, kwaye baqinise uhlolo loxinzelelo lwelori yetanki, iiflange zepayipi ukuze kubonwe ukuvuza, njl.njl., igesi yelori yetanki. Yiphinde uyibuyisele kwinkqubo ngokufanelekileyo kwaye ungayikhuphi ngokuthanda kwayo. Ukuba kukho imeko engaqhelekanga efana nokuvuza, yeka ukuzalisa ngoko nangoko, kwaye uthathe amanyathelo asebenzayo okuthintela iingozi ezingalindelekanga.
Ukuhlolwa rhoqo kwezixhobo zokufakela i-ammonia, amanyathelo kunye neenkqubo kuya kwenziwa imihla ngemihla, kwaye kufuneka kwenziwe iirekhodi zokuhlola nokuzalisa.
