Ingeniso yeshishini i-caprolactam elungileyo yaqala ukugcina inqanaba eliphezulu

Petrochemical, Haili, Qinghua yokupaka. Imveliso yeCangzhou Xuyang isigaba I iphinde yaqala, iYongrong igcwele, ukugcinwa kweSanning kulibaziseke kancinane, umthwalo wecaprolactam kulindeleke ukuba uhlale uphezulu kwixesha elizayo elingekude, kwaye unikezelo lwe-co-production ammonium sulfate luya kwanda ngokufanelekileyo.

Imijikelo emithathu yokunyuka kwe-coke ilinganiselwe

Kungekudala, isampuli epheleleyo yamashishini e-coke azimeleyo aseChina: izinga lokusetyenziswa kwamandla lalingama-73.3%, phantsi kwe-0.5% ukusuka kwixesha elidlulileyo. Okwangoku, imarike ye-coke iyaqhubeka isebenza ngamandla. I-Coke kumjikelo wesithathu wamahla ndinyuka, ukunyuka okukhawulezileyo kwakutshanje kwamaxabiso e-coke, umoya wokurhweba ushushu, umsebenzi wentengiso unyuke kakhulu, uxinzelelo lweendleko zamashishini e-coke lunyukile, uninzi lwamashishini e-coke anelahleko, kwaye amanye anelahleko. kulindeleke ukunciphisa imveliso.

Okwangoku, ukunikezelwa kwe-ammonium sulfate kwiinkqubo ezimbini eziphambili ze-ammonium sulfate e-China kuzinzile, nangona ukuqala kwamashishini e-coke kuye kwehla kancinci, kodwa ukuqala kwamashishini e-caprolactam kuye kwagcina izinga eliphezulu, kunye nokunikezelwa kwe-co-co- imveliso ammonium sulfate iye yanda. Kwicala lemfuno, amaxabiso e-urea yamazwe ngamazwe anyukile, edityaniswa ne-Indiya ngoko nangoko yakhupha umjikelo omtsha weendaba zebhidi ye-urea, kunye neemvakalelo ezikhulayo zekamva, amaxabiso amabala anyuka ngamandla, esonyusa isimo sengqondo soshishino, kwaye umdla wokubuza wabathengisi ulungile. Ngokubhekiselele kurhwebo lwasekhaya, izinga lokusetyenziswa komthamo wesichumisi esihlanganisiweyo liyaqhubeka nokunyuka, ukusuka kwiindawo eziqhelekileyo, kuquka ummandla weHubei, amashishini amakhulu amakhulu kunye nokuhamba phambili, ukwenzela ukuba kuqinisekiswe ukunikezelwa, izinga lokusebenza liye landa kakhulu. Okwangoku, imfuno yesayithi ilungile, ixhasa ukusebenza kwe-ammonium sulfate kwinqanaba eliphezulu. Ukuqwalasela ukuba emva kokunyuka okuqhubekayo, ubunzima babanye abavelisi abasezantsi ukuba balandele ukunyuka, kulindeleke ukuba imarike ye-ammonium sulfate yexesha elifutshane iphezulu kwaye incinci, kwaye ingqwalasela engakumbi ihlawulwa kwimeko yomyalelo wemarike yamazwe ngamazwe.
