Serivise nziza ＆ Porogaramu zidasanzwe

Serivisi isobanuramu gutanga imiyoboro ntabwo "H₂S irahari." Bisobanura guhuzaH₂S igitutu igice, ubushyuhe, pH, na chlorideirashobora gutwara hydrogene mubyuma no gukururaSSC / HIC, inzira yinzira rero namategeko yo kwemererwa bigomba gukurikiza ibipimo bya - aho gukurikiza umurongo rusange.

Urugero:Raporo y'amazi yerekana1.000 ppm H₂Sirashobora kugaragara "iringaniye," ariko kuri100 barigitutu cyuzuye gisobanura~ 0.1 bar ppH₂S, birakomeye bihagije kubakoresha benshi kugirango bongere ibisabwa kubigenzura no gukomera. Ibinyuranye, ppm imwe 1.000 kuri10 barni gusa~ 0.01 bar ppH₂S, akenshi biganisha ku cyemezo cyamasoko atandukanye cyane.
Niyo mpamvu guhitamo - serivisi ihitamo ikorwa naraporo ya chimie raporono kuyobora bisanzwe (muri rusangeNACE MR0175 / ISO 15156) - n'impamvu Umuyoboro wa Octal usaba ibahasha ya serivisi (ppH₂S / pH / ubushyuhe) mbere yo kwemeza isoko - ibikoresho bya serivisi.

Mu nganda za peteroli na gazi, peteroli, inganda, hamwe n’umuvuduko mwinshi - umuvuduko / hejuru - ubushyuhe (HPHT), porogaramu zitanga serivisi zisaba ibisabwa cyane ku byiciro by’icyuma, ibigize imiti, gutunganya ubushyuhe, ubuziranenge bwo gusudira, gutwikira, no kwihanganira ibipimo. Hatabayeho kugenzura neza, ibidukikije bikarishye birashobora kugira ingaruka zikomeye kuburinganire bwumutekano, umutekano, nubuzima bukora.

Umuyoboro wa Octal utanga serivisi zisharira hamwe numuyoboro udasanzwe wo gukoresha umurongo wujuje ubuziranenge bwisi ku isi.

Serivise nziza H₂S ppmni icyerekezo cyo kwibandaho, arikontabwo isobanura ubukana bwonyine. Ibyinshi bisharira - ibikoresho bya serivisi byujuje ibyangombwaH pressureS igitutu cyigice (ppH₂S)kuberako gukuramo ibyago bigengwa nuimbaraga zo gutwara hydrogène, ikiyongera hamwe nigitutu cyigice. Mubyerekeranye nubuhanga, ppH₂S igomba gusuzumirwa hamwepH, chloride, ubushyuhe, hamwe nicyiciro cyamazi kiboneka, kuberako ibipimo bigira ingaruka zikomeye kuri SSC / HIC.

Ihinduka rifatika rya gaze - kwerekana icyiciro ni:

ppH₂S=(H₂S agace gato) × (igitutu cyuzuye)

• Kubigize gaze,agace gato ≈ ppm / 1.000.000(ishingiro rya ppmv).
• Koreshaigitutu cyuzuye(ntabwo ari igipimo).
• Inyandiko z'igice:Akabari 1=100 kPa; 1 psi ≈ 6.895 kPa.

Ingero zakozwe (ppm imwe, ubukana butandukanye):

• 1.000 ppm=0.001. Kuri100 barigitutu cyose: ppH₂S=0.001 × 100 =0.1 bar.
• Kimwe1.000 ppmkuri10 barigitutu cyose: ppH₂S=0.001 × 10 =0.01 bar.
• Nubwo ppm isa, urubanza rwa kabiri rufite10 × hepfo ppH₂S, mubisanzwe biganisha kubintu bitandukanye / kugerageza ibisabwa mubisobanuro byumushinga.

Impamvu ibi bifite akamaro ko kugura imiyoboro:

Nkuko ppH₂S yiyongera, imishinga isanzwe ikomeza kugenzura kubintu bitwara SSC / HIC ibisubizo - kenshiimipaka igoye (cyane cyane weld / HAZ), isuku yicyuma / kugenzura kwinjiza, hamwe nubushobozi bukenewe bwo kwipimisha / igipimo (HIC / SSC mugihe cyagenwe). Niyo mpamvu itegeko ryo kugura rivuga gusa "H₂S=X ppm" akenshi bidahagije kugirango urangize ibikoresho - ibikoresho bya serivise. Mu myitozo, H₂S (ppmv cyangwa mol%),igitutu cyose, ubushyuhe,pH, chloride, kandi niba icyiciro cyamazi yubusa kibaho. Hamwe nibi, ppH₂S irashobora gushirwaho kandi inzira yibikoresho (hamwe nibisabwa ibyangombwa / kwipimisha) birashobora gushyirwaho muburyo budasubirwaho. Umuyoboro wa Octal usanzwe usaba ibahasha ya serivisi (ppH₂S, pH, ubushyuhe, chloride, nicyiciro cyamazi) mbere, hanyuma ugahuza inzira yibikoresho hamwe nurwego rwerekana ibyateganijwe kugirango umushinga utangire gusubiramo tekiniki bitinze -.

Ibikoresho bya serivisi bikeneweBashyizweho kugirango birinde SSC / HIC kunanirwa, bityo itegeko rigomba gusobanura umuyoboro nka aibikoresho bya serivise nziza- ntabwo ari OD / WT gusa n amanota. Mubikorwa, gahunda yo kugura igomba kuvuga neza:

• Kugenga ibipimo bisharira:NACE MR0175 / ISO 15156 (kandi nikihe gice gikurikizwa), hiyongereyeho umukoresha / ibigo byihariye.
• Ibahasha ya serivisi (ishingiro ryo guhitamo):ppH₂S (cyangwa H₂S ibigize + umuvuduko wuzuye), pH, ubushyuhe, chloride, kandi niba amazi yubusa ahari.
• Igipimo cyo kugenzura ibikoresho:kugenzura imiti (incl. isuku / inclusions), inzira yo gukora ibyuma nkuko bisabwa na spec, inzira yo kuvura ubushyuhe, hamwe nifatizo ryo kugenzura ubukana.
• Kwipimisha neza (mugihe bisabwa na spec):Impamyabumenyi ya HIC / SSC, inshuro nyinshi, hamwe nibisabwa.
• PSL / ibisabwa byiyongera:urugero, API 5L PSL2 hamwe nibisabwa - ibisabwa byinyongera bya serivisi aho bishoboka.
• Igenzura rya Weld / HAZ (niba umuyoboro wo gusudira byemewe):Weld seam NDT igipimo hamwe nibisabwa / ibisabwa bisabwa n'umushinga ITP.

Uburyo Octal Umuyoboro ushyigikira amasoko - amasoko ya serivisi:Umuyoboro wa Octal mubisanzwe utangirana naibahasha ya serivisihanyuma yubaka isubiramo - ipaki yiteguye hafi yayo - yemeza niba umuyoboro wibyuma bya karubone byemewe cyangwa niba kuzamura (kugenzura ubukana bukomeye, kugerageza impamyabumenyi ikomeye, CRA / yambaye / umurongo) bikenewe kugirango byemezwe.
