Amanqaku ama-4 ekufuneka Uwazi Ukukhetha Imitha yeNdawo ephathwayo yerhasi yeNdalo

imitha ephathekayo yombethe sisixhobo esilungileyo kwiinjineli ezisebenza entsimini kwaye zinokusetyenziswa ngokubambisana ne-intanethi ye-hydrocarbon kunye namanzi

abahlalutyi bendawo yombethe ukuqinisekisa umgangatho werhasi yendalo. Umhlalutyi we-intanethi ubonelela ngomlinganiselo oqhubekayo we-intanethi we-hydrocarbon dew point (HCDP)

kwigesi yendalo. Ngokuchaseneyo, iimitha zombethe eziphathwayo zibonelela ngovavanyo olukhawulezayo nolulula lwe-HCDP kunye neendawo zombethe wamanzi kwiindawo ezahlukeneyo zesampulu kwinkqubo.

Okokuqala, Kutheni Kubalulekile Ukulinganisa Indawo yoMbethe yeeHydrocarbons kunye naManzi?

Zombini i-hydrocarbon kunye nendawo yombethe wamanzi zezona parameters eziphambili zomgangatho werhasi yendalo. Ngokulinganisa ngokuhambelana ne-ISO6327 okanye i-ASTM D1142,

yonke igesi yendalo esasazwayo kufuneka ihambelane nemigangatho yerhasi yamazwe ngamazwe yokusasazwa, ukugcinwa, ukuhanjiswa nokusetyenziswa kwayo,

njenge CEN -- EN16726.

Ngelixa i-intanethi ye-hydrocarbon kunye nabahlalutyi bendawo yombethe bafakwe kwiindawo eziphambili kwindawo nganye (ezifana nokunqumla urhwebo kwimibhobho yegesi yendalo),

izixhobo zombethe eziphathwayo zibalulekile kwiinjineli ukuba zivavanye umgangatho wendalo kwiindawo ezahlukeneyo zesampulu kuyo yonke le nkqubo. Oku kuvumela

bachonge iindawo ezivuzayo okanye bajongane neziphene kwaye bachonge naziphi na iingxaki zomgangatho kwindawo ethile. Njengenxalenye yesicwangciso solondolozo lwesiqhelo,

umvavanyi ophathwayo wombethe udla ngokusetyenziswa ukuqinisekisa imilinganiselo yomhlalutyi we-intanethi.

Imitha yendawo yombethe ephathwa ngesandla inokulinganisa ngokukhawuleza idatha yendawo yombethe kwaye ilungelelanise iziphumo zabanye abahlalutyi bendawo yombethe.

Hk-J8A103 ubushushu obuphathwa ngesandla kunye nesixhobo sokulinganisa ukufumat enendawo yombethe, ibhalbhu eyomileyo nemanzi, ubushushu kunye nokufuma

umsebenzi wokulinganisa, umatshini omnye oneenjongo ezininzi, ulula kwaye ulungele. I-chip ye-RHT ethathwe ngaphandle, impazamo yomlinganiselo ophezulu wokuchaneka

encinci, ilungele zonke iintlobo zeshishini lokuvelisa oomatshini bokuchaneka okuphezulu.

Okwesibini, Unokukhetha njani uMvavanyi weNdawo yoMbethe ophathwayo

Iimodeli ezininzi zeimitha yenqaku lombethe ephathwayo kunye nabahlalutyi bendawo yombethe behydrocarbon abaphathwayo bayafumaneka kwimarike.

Le mibuzo iya kukunceda uthelekise iimpawu kunye nezibonelelo zeemodeli kwimarike:

1.Ngaba inaso isiqinisekiso sommandla wehlabathi wengozi?

Ukukwazi ukusebenzisa umvavanyi wendawo yombethe ukulinganisa iindawo zombethe ngokuthe ngqo kwiindawo ezinobungozi ngaphandle kwesidingo semvume yokusebenza esebenzayo kuthetha.

ukuba imilinganiselo inokwenziwa ngokukhawuleza nangokulula. Umzekelo, abasebenzi benkxaso banokulinganisa iimpendulo ezikhawulezayo ngendawo

ijonga ukufumanisa unobangela wokuphazamiseka kwenkqubo. 

2. Ngaba ilula kwaye iyaphatheka?

Ihamba ngaphandle kokutsho ukuba isixhobo sokulinganisa umbethe esiphathwayo kufuneka kube lula ukusiphatha kwaye sibe nobomi obude bebhetri ukuze

inokwenziwa ngokuthembekileyo kwintsimi kwaye ithuthwe ngokulula.Hengko608 series dewpoint transmittersziyaphatheka kwaye zixinene,

ilungele ukulinganisa imibhobho yegesi, iibhokisi kunye nezinye iindawo ezimxinwa. 

3. Ngaba iziphumo zomlinganiselo zithembekile?

Bonke abavavanyi bendawo yombethe ababonakalayo bezandla basebenzisa itekhnoloji yesipili esibandayo ukulinganisaiindawo zombethe we-hydrocarbon. Nangona oku kuninzi

indlela ethembekileyo yokumisela iindawo zombethe, njengoko ixhomekeke ekuqwalaseleni ngokuthe ngqo ukubunjwa kwe-condensation kwisibuko sokupholisa;

kukho umahluko kwindlela obu buchule busetyenziswa ngayo. Ikhono lokubonelela ngedatha echanekileyo kunye nenjongo kwindawo nganye yokulinganisa

Kubalulekile kwakhona xa ukhetha isixhobo, kwaye ayizizo zonke iimodeli ezibonelela ngoku.

4. Ngaba iyahlangabezana nemigangatho yomgangatho werhasi yamazwe ngamazwe?

Njengoko kukhankanyiwe ngasentla, igesi yendalo kufuneka ihlangabezane nemigangatho yamazwe ngamazwe efana ne-CEN16726 okanye i-easee-gas cbp-2005-001-02. Nayiphi na

ephathekayoumvavanyi wendawo yombethekufuneka abe nokuchaneka okufanelekileyo ukuhlangabezana nezi mfuno.
