Incazelo:

Ipayipi lensimbi lezinsizakalo ezimuncu lisetshenziselwa amapayipi endaweni egqwalayo.

Kuzodala ukuvuza kwepayipi likawoyela negesi, kwezinye izimo ngisho nokuqhuma.Ukugqwala kwamapayipi kuyingozi enkulu ekuphepheni komuntu siqu kanye nokungcoliswa kwemvelo, ngakho-ke ukukhiqizwa kwepayipi elimuncu kubalulekile.

Ipayipi lenkonzo emuncu lisetshenziswa ikakhulukazi endaweni ye-H2S.Nakuba i-H2S ingamakhemikhali ayingozi ngokuvamile alula ukwenza ukugqwala.

Uma ukucindezela kwengxenye ye-H2S ifinyelela ku-300 pa, amapayipi olayini asetshenzisiwe azoba nokusebenza kokubola kwe-asidi.Ipayipi lesevisi elimuncu lihlanganisa ipayipi le-NACE.

Indlela yokwenza ipayipi yesevisi emuncu eyenziwe:

I-API Spec 5L, insimbi yepayipi esetshenziselwa ipayipi lenkonzo emuncu iyinsimbi ebulewe ngokuphelele.

Kumele kuqashelwe ukuthi, ukuhlanzeka okuphezulu kwensimbi kungaqinisekisa i-S ephansi, P nokunye ukungcola.

Izinga lokulawula nokuhlolwa kokuma kokufakwa kwensimbi yepayipi yepayipi yesevisi emuncu iyadingeka ngoba ukuqhekeka okubangelwa i-hydrogen okubangelwa ukufakwa kuqala kunqunywa ngendlela yayo.

Izakhiwo zamakhemikhali:

Okuqukethwe kwe-C, P, S kanye ne-carbon okulingana nokwakheka kwamakhemikhali epayipi lesevisi emuncu kuphansi uma kuqhathaniswa namapayipi avamile, anezidingo zokulawula ngokuqinile.

Ikakhulukazi kokuqukethwe okungu-S, kuyisici esiyingozi kakhulu ezindaweni ezigqwalile, ngakho-ke ipayipi lesevisi elimuncu kufanele lilawule u-S esiphezulu ongu-0.002.
