Amabwiriza yo Kwita ku Gushyiramo
VJP(imiyoboro y'imyenda idafite isuku)mbere yo gushyiraho, bigomba gushyirwa ahantu humutse hatarimo umuyaga.Itsindaiy'inyumagupfunyikaurwego rwa VJP ntirushoborabe funguraed, kugira ngo hirindwe ko umuyoboro winjira mu bintu by'amahanga (umusenyi, utunyabuzima duto, nibindi). Mu gihe cy'imvura cyangwa igihe kirekiregutoseikirere, kandi bagomba kwita cyane ku gice cy'imbere cy'umuyoboro kidapfa amazi.
Birabujijwe gukoresha VJP mu buryo butaziguye nk'amashanyarazi yo gusudira, agace k'impakacyangwa gusudira kuri VJP.
VJPgupfunyikaurwego ntirushobora gukurwaho kugeza igihe umuyoboro ushyiriweho kugira ngo hirindwe ko gusudira kwangirika mu zindi nzira.
Mu gihe cyose cyo gushyiraho, VJP igomba kwitabwaho nezaRinda impande zombiya VJP, ntugakoresheimashini ikoresha umwuka udafite umwukaagace ka VJP (ishusho ya 1 na 3) nk'ingufu zo gukumira gusohoka kw'umwuka uva mu kirere.
Mu gihe ushyiraho, witondere uburyo bwo kuzamura icyuma, ntugapfe cyangwa ngo wangirike.
Intambwe zo gushyiraho VJP
1. Igenzuraiigishushanyos, niba ingano n'inganoy'imiyoboroku bishushanyo ni bimwehamwe naiimiyoboro yo mu murimaBmbere yo gushyiraho, shakahanzeburi VJP hakurikijwe igishushanyo mbonera naumubareUrugero:HL2018GLN-59-02-01, bivuze ko kode y'umushinga ari 59, imiterere ya azote y'amazi, umuyoboroOya.01 y'umurongoOya.02. Icyapa cy'icyuma gifite ikiumubareifatanye na VJP aho hantu (ishusho ya 1), kandi hashyizweho icyapa cy'amashanyarazi cyo kwangirikahafi y'aho icyuma gifunga umwuka kiri kuriiVJP(Ishusho ya 2).
Icyitonderwa:inganokandi Oya.y'imiyoboro iri mu gishushanyo igomba kuba imwe n'iyainganonaOya.byaVJPsku kazi. Niba hari itandukaniro mu igenzura, menya neza ko wavugana n'abakozi bacu ku kazi.

3. Mbere yuko flanges zihuzwa, banza urebe niba impeta zo gufunga n'icyuma gifunga gikonje byashyizweho neza
4. Sukura ingingo zaumugore n'umugabokongera igiheumuyoborokasheimpetan'icyuma gifunga ibintu gikonje gifite reagent idafite amavuta n'amazi.
5. Shyiramo umuyoboro w'ingabo n'umugore ugororotse kandi buhoro buhoro. Hanyuma ukuremo uduce tubiri tw'ingufu hanyuma ukande, hanyuma ushyiremo imigozi yose ku duce tw'ingufu (ntuyishyiremo vuba).
6. Nyuma yo kugenzura neza aho flanges ebyiri ziherereye, komeza ibyuma buhoro buhoro. Menya neza ko flange iguma iringaniye mu gihe cyo kuyishyiraho
7. Reba niba gufunga flange byujuje ibisabwa.
8. Itsindahagati y'inkunga ebyiri ni metero 3, icyapa cya PTFE kigomba gushyirwa hagati y'aho inkunga iherereye n'ahoiy'inyumaumuyoboro.
Ibisobanuro birambuye ku mikorere n'imitangire
1. Abakora bagomba kuba bazi neza ibijyanye n'akazigutembas hagati y'ibikoresho biri muri sisitemu. Bikwiye kumenyekana ko ogisijeni y'amazi, azote y'amazi na argon y'amazi ari ibintu bitera umwijima. Iyo ubushyuhe bw'ikirere buri hejuru y'aho ubushyuhe bubera, biba bisanzwegasifykandi iterwa n'umuvuduko, bigatuma umuvuduko wiyongera buhoro buhoro muVJP n'ibindi bifitanye isanoibikoresho.
2. Gukonjesha VJP mbere yo kuyikoresha
Kubera ko VJP idakoreshwa iba iri ku bushyuhe bw'ikirere, umuyoboro wuzuyemo umwuka urimo ubushuhe. Kubwibyo, intego yo gukonjesha mbere ni: icya mbere, kugabanya buhoro buhoro ubushyuhe bwa VJP kugeza ku bushyuhe bw'amazi ashyushye, kugira ngo hirindwe ko amazi menshi ashyushye ashobora gukorana n'umuyoboro usanzwe w'ubushyuhe, bigatuma habaho ubwinshi bw'umwuka wihuta kandi mwinshi, bigatuma VJP irushaho gukandagira, bityo bikangiza VJP n'ibikoresho bya terminal liquid. Icya kabiri, ni ugukuramo buhoro buhoro umwuka uri muri VJP no kwirinda ko amazi menshi ashyushye ashobora gukorana n'umwuka, bigatuma VJP ikomeza gukonja no kuziba imbere.
Mbere yo kongera gukoresha umuyoboro wa adiabatic ukoresha vacuum nyuma yo kuwukoresha bwa mbere cyangwa kuwuhagarika, hagomba gukorwa gukonjesha mbere y’uko umuyoboro wa adiabatic ukoresha vacuum ushobora gukora neza nyuma yuko ugeze aho ukorera.
3.IcyoUburyo bwo Gukonjesha Mbereya VJP
Ubwa mbere, reba niba valves, igipimo cy'umuvudukosn'agakoresho k'umutekanon'ibindi.muri sisitemu ya VJP bari mu mimerere isanzwe ijyanye nayo. Nyuma y'ibivuzwe harugurugenzurairangiye, fungura buhoro buhorovalve y'ubwinjiriro bwa sisitemu ya VJPkandi uhindure umwuka/gasifyamazi adatemba cyane mu mwuka ukonje kugira ngo-gukonjeshaVJPkurikubyerekeyeIminota 30. Igitutu kiri muVJPirahindagurika cyanemuri iki gihe.Iyo igitutu kiri muriVJPihinduka ihamye, ingano y'inyongera ishobora kwiyongera buhoro buhoro kugeza igihe yujuje ibisabwa.(Icyitonderwa: mu gihe cyo gukonjesha mbere yo gukonjesha, niba igitutu kiri muVJPiri hejuru y'umuvuduko ujyanye n'igishushanyo mbonera,bigomba guhita bibaho ako kanyayahagazegutera umuti muri sisitemu ya VJP.MIgihe kimwe,fungura burunduumwukavalvesku murongo kugira ngo barekure igitutu.)
4. SAkazu HasiVJP
Mu guhagarika guterwa, birabujijwe cyane gufunga valve zombi z'uburyo bwa VJP icyarimwe, kugira ngo bibe closed muriVJPsisitemu, bigatuma amazi asigaye arushaho gushyuha cyane muri VJPbitewe no gukwirakwiza gaze.
5. Igihe runakaDischarge yaCryogenicLibirayi (LikiyidiOogisijeni gusa)
Kubera ko hydrocarbon n'ibisigazwa bibaho muriVJP yaogisijeni y'amazi, ibi bintu bizashyirwa mu muyoboro w'imbere igihe kirekire iyo binyujijwe muVJP.Iyo hydrocarbons zishyizwe mu muyoboro ari nyinshi kandi igihe kirekire, uko ikirere gishyuha cyangwaumusaruro waogisijeni y'amazi irakomezaipakiye, ubwinshi bw'ibinyabutabire bya hydrocarbon muVJPkwiyongera, kandi uburyo umwuka wa ogisijeni usigaye bushobora guteraanguturikasion.
6.UmutekanoDumukoziya VJP
Muri buri kimwe muri ibyoVJPSisitemu igomba gushyiraho sisitemu yo gusohora amazi mu buryo bw'umutekano (harimo na valve yo gufasha n'ivali yo guhumeka), Iyo umuvuduko wa VJP ugeze ku muvuduko wo gufungura wa valve zo kurinda umutekano uzifungura ubwazo kandi zigasohora umuvuduko ku gihe. Muri icyo gihe,umwukaValve zishobora kandi gufungurwa n'intoki kugira ngo zirekure umuvuduko kugira ngo sisitemu yose ya VJP ikomeze kugira umutekano.
