Ingcaciso:

Iinkonzo ezimuncu umbhobho wentsimbi usetyenziswa kwimibhobho kwindawo engcolisayo.

Iya kubangela ukuvuza kombhobho we-oyile nerhasi, kwezinye iimeko nogqabhuko-dubulo.Ukonakala kwemibhobho kunomngcipheko omkhulu wokhuseleko lomntu kunye nongcoliseko lokusingqongileyo, ngoko ke ukuveliswa kombhobho wenkonzo emuncu kubalulekile.

Umbhobho wenkonzo emuncu usetyenziswa ikakhulu kwindawo ye-H2S.Ngelixa i-H2S iyikhemikhali eyingozi ekulula kakhulu ukwenza umhlwa.

Xa uxinzelelo oluyinxenye lwe-H2S lufikelela kwi-300 pa, imibhobho yomgca esetyenzisiweyo iya kuba ne-anti-acid corrosion performance.Umbhobho wenkonzo omuncu uquka umbhobho we-NACE.

Indlela yokwenza umbhobho wenkonzo omuncu eyenziwe:

I-API Spec 5L, intsimbi yombhobho esetyenziselwa umbhobho wenkonzo emuncu icocekile intsimbi ebulewe ngokupheleleyo.

Kuya kuqatshelwa ukuba, ukucoceka okuphezulu kwentsimbi kunokuqinisekisa i-S ephantsi, i-P kunye nezinye izinto ezingcolileyo.

Umgangatho wokulawulwa kunye nokuhlolwa kokubandakanywa kwemibhobho yensimbi yombhobho wenkonzo emuncu iyadingeka ngenxa yokuba ukuchithwa kwe-hydrogen okwenziwe yi-hydrogen okubangelwa ukufakwa kuqala kunqunywe kwifom yayo.

Iimpawu zekhemikhali:

Umxholo we-C, P, S kunye nekhabhoni elingana nokwakhiwa kweekhemikhali zombhobho wenkonzo emuncu uphantsi kakhulu kunemibhobho yomgca oqhelekileyo, kunye neemfuno zokulawula ngokungqongqo.

Ngokukodwa kumxholo S, iyinto eyingozi kakhulu kwindawo enomhlwa, ngoko kumbhobho wenkonzo emuncu kufuneka ulawule ubuninzi be-S 0.002.
