Kwi-workshop yaseJinbin, iqela leiivalvu zebhola zentsimbi ye-carbon ezijijekileyoziyapakishwa kwiibhokisi ukuze zithunyelwe.

Zithini izicelo ezithile zentsimbi yekhabhoni ejikelezileyoivalvu yebhola?

I. Iimeko eziphambili kwiShishini lePetrochemical

Njengentsimi esetyenziswa kakhulu, ifanelekile kwiimeko zokusebenza ezifana nokucocwa kweoyile eluhlaza kunye nokuhlanganiswa kweekhemikhali. Umzekelo, kwiipayipi zokuthutha iimveliso zeoyile ezishushu kakhulu zeenkampani zokucocwa kunye neekhemikhali, iimpawu zazo zokuvula nokuvala ngokukhawuleza zinokuthintela ukugcinwa okuphakathi kunye nokubola. Ulwakhiwo olungatshiyo kunye noluchasene nokuma luhambelana nomgangatho we-API 607, ukuqinisekisa ukhuseleko lwemveliso.

Ii. Ukusetyenziswa kweeNkqubo zamandla oMbane

Kwiiprojekthi zamandla obushushu kunye nokuveliswa kwezixhobo ezifanayo, isetyenziselwa imibhobho yamanzi kunye nokuhambisa umphunga kwibhoyila. Ifanelekile kwiimeko zokusebenza zomphunga oxinzelelo oluphezulu kunye nobushushu obuphezulu, ukuzinza koqhagamshelo lweflange kunokumelana nokungcangcazela kwemibhobho, kwaye inkqubo yokubumba iyonke yomzimba wevalvu iphucula amandla okumelana nokuguquguquka koxinzelelo. Kwiinkqubo ezincedisayo zamandla enyukliya, ishishini levalvu yebhola elenziwe ngentsimbi yekhabhoni eshushu ephantsi (LCB) linokulungiswa kwiimeko ze-cryogenic ze--46 ℃, libonelela ngolawulo oluthembekileyo lokuvala imibhobho yamanzi okupholisa.

Iii. Amakhonkco abalulekileyo kwiShishini leMetallurgical

Isetyenziswa kwinkqubo yokuhambisa igesi yokupholisa kunye ne-blast furnace kwi-smelting yentsimbi. Xa ivezwe kwi-media equlethe uthuli kunye nezinto ezirhabaxa kancinci, umzimba wevalvu yentsimbi yekhabhoni udityaniswa neebhola zentsimbi engagqwaliyo eqinileyo ukuze imelane nokukhukuliseka kwamasuntswana kunye nokuguguleka. Ulwakhiwo oluzicocayo lwesihlalo sevalvu lunciphisa umngcipheko wokuvaleka. Kwipayipi yonyango lwegesi ye-converter flue, iimpawu zayo ze-torque encinci yokusebenza kunye nokuvulwa nokuvalwa ngokukhawuleza zinokuphendula ngokukhawuleza kutshintsho loxinzelelo lwenkqubo kwaye ziqinisekise ukusebenza kakuhle kokucocwa kwegesi ye-flue.

Iv. Iimeko zeMizi-mveliso zikaMasipala nezeMizi-mveliso Jikelele

Kwiiprojekthi zokubonelela ngamanzi kunye nokucoca amdaka ezidolophini, ivalvu yebhola ye-intshi ezi-4 eyenziwe ngentsimbi ephosiweyo kunye nentsimbi yekhabhoni ifanelekile kwiindawo ezingabolisiyo ezifana namanzi epompo kunye namanzi ajikelezayo. Zibonelela ngentsebenzo entle kakhulu, kwaye uqhagamshelo lweflanges lwenza kube lula ukugcinwa kunye nokuhlolwa kamva. Kwimibhobho yokubulala iintsholongwane ngomphunga kwimizi-mveliso yamayeza kunye nokutya, iivalvu zebhola zekhabhoni ezingenazo iindlela zokuhamba kwekona ezifileyo zikhethwa ukuthintela intsalela ephakathi kunye nokuhlangabezana neemfuno zococeko.

V. Ukusetyenziswa kwiCandelo loThumelo lweGesi kunye noSasazo

Kwizikhululo zamasango asezidolophini kunye nemibhobho yegesi yendalo ekude, ivalvu yebhola yentsimbi yekhabhoni ejijekileyo iye yaba zizixhobo eziphambili zokunqumla okuphakathi ngenxa yokuvala kwayo okungatshiyo kunye noyilo oluchasene nokuma. Isakhiwo sebhola esizinzileyo sifanelekile kwimibhobho emikhulu ukusuka kwi-DN50 ukuya kwi-DN600. Iqinisekisa ukuvalwa okuzinzileyo phantsi koxinzelelo oluphezulu kakhulu kwaye inokudityaniswa kude nenkqubo ye-ESD ukuze kufezekiswe ukuvalwa okungxamisekileyo, okuqinisekisa ukhuseleko lokudluliselwa kwegesi.
