API 641 vs. ISO 15848-1: Ubuyobozi bwo guhitamo valve y'umupira isohora umwuka muke

Incamake y'incamake: Ni irihe tandukaniro nyamukuru riri hagati ya API 641 na ISO 15848-1?

API 641 ni uburyo bworoshye bwo gusohora/gutsindwa bw’Abanyamerika bwagenewe by’umwihariko vali zo guhindukira zikoresha methane (CH₄), zifunga amazi kuri ≤ 100 PPMv kandi zemerewe guhindura imiterere y’udutsi two gupfunyika. ISO 15848-1 ni uburyo bwo gushyira mu byiciro rusange (Ibyiciro A, B, C) hakoreshejwe methane cyangwa heliyumu, bushobora kwakira urwego rw’ubudahangarwa bw’imashini (ingendo 2,500 kugeza 10,000+) kandi bugatanga uburyo bwo guhindura imiterere y’udutsi.

1. Intangiriro: Kurwanya imyuka ihumanya ikirere ituruka ku guhunga

Mu nganda zigezweho zitunganya peteroli n’izitunganya imiti, uduce dufungamo utubuto tw’ingufu n’ingingo z’umubiri bigira 60% by’imyuka yose ihumanya ikirere (VOC). Uretse kubahiriza ibidukikije—nk’amabwiriza ya US EPA Method 21 cyangwa amabwiriza ya REACH y’i Burayi—gusohoka kw’utubuto mu buryo budagenzurwa biteza ingaruka zikomeye ku mutekano, byihutisha igihombo cy’ibicuruzwa, kandi bigashyira mu kaga impushya zo gukora ku nganda. Ikigo Mpuzamahanga Gishinzwe Ingufu kivuga ko 30% by’imyuka yose ya methane iva mu bikorwa bya peteroli na gaze ituruka ku gusohoka kw’ibikoresho birimo na za valve.

Iyo ibigo by’ubuhanga mu gutanga amasoko n’ubwubatsi (EPC) cyangwa amatsinda ashinzwe kubungabunga uruganda agennye uburyo bwo gupima imyuka ihumanya ikirere (Low-E) mu gihembwe cya kane, bihuye n’amahame abiri y’ibanze mpuzamahanga yo gupima ubwoko: API 641 na ISO 15848-1.

Guhitamo ibipimo bidakwiriye cyangwa gusobanura nabi ibyiciro by’ibizamini bishobora gutuma kohereza valve byanze, igenzura rya EPA ryakozwe nabi, cyangwa ikiguzi cyo kubisobanura birenze urugero bitari ngombwa. Muri iyi nyandiko, dushingiye ku bunararibonye bwacu mu by’ubuhanga mu mishinga ya valve ya E yemewe n’uruhande rwa gatatu kugira ngo dusesengure itandukaniro ry’ingenzi, protocole zo gupima, n’imiterere yo gupakira stem ikenewe kugira ngo hagerwe ku kubahiriza amategeko y’ibizamini.
