Umsebenzisi: Iplanti yokuLungisa irhasi yeNdalo eChangqing Oilfield
Njengeyona yunithi inkulu yendalo yokubuyisela i-ethane yegesi e-China, iplanti yegesi yendalo e-Changqing Oilfield yiprojekthi ephambili ye-CNPC yokuphucula umgangatho kunye nokusebenza kakuhle. Ukufezekisa unikezelo lwezixhobo ekrwada inkqubo yokuvelisa ethylene ukusuka ethane ngokukhawuleza kangangoko kunokwenzeka, le projekthi amkelekanga kuphela phambili ngamazwe "ifriji ifriji + Ukwandiswa ifriji + igesi kabini overcooling + ubushushu obuphantsi distillation" ethane recovery iteknoloji engundoqo umzimba, kodwa wamkela iteknoloji ephambili kuyilo lobunjineli kunye nokwakhiwa. iqonga loyilo, "kunye nemowudi yomjikelezo wobomi obugcweleyo", ukufezekisa ulawulo lwedijithali kunye nobukrelekrele benkqubo yonke yoyilo, ukuthengwa, ukwakhiwa, ukusebenza kunye nokugcinwa.
Emva kokugqitywa kweplanti yokucoca igesi yendalo, inokuqonda ukusetyenzwa konyaka kwe-20 billion cubic metres zegesi yendalo, imveliso yonyaka yeetoni ze-ethane ezizigidi ezisisi-1.05, iitoni ezingama-450,000 kunye ne-hydrocarbon ezinzileyo, elingana nexabiso lemveliso yentsimi yeoli yasekhaya, ikwaphawula ukuba uphuhliso lwegesi yendalo yaseTshayina luye lwagqiba uphuhliso lwerhasi yendalo, kodwa lugqibezele uphuhliso lwerhasi yendalo. uphuhliso olukumgangatho ophezulu oluvaliweyo lwetyathanga leshishini leCNPC eShaanxi.
Amanzi ajikelezayo avale inkqubo yokupholisa yesixhobo sokulungisa igesi yendalo isebenzisa ukupholisa komoya + ukupholisa kwamanzi ukupholisa amanzi ajikelezayo. Ngenxa yamanzi okupholisa amanzi ajikelezayo avaliweyo okupholisa inqaba isebenzisa amanzi aphantsi komhlaba ngokuthe ngqo njengamanzi ongezelelweyo, inkqubo inotyekelo olucacileyo lokukhula emva koxinaniso, kwaye kulula ukuyifaka kwaye ibambelele kwi-tower yokupholisa i-filler, isixhobo sokutshiza, kunye neetyhubhu zokutshintshiselana kobushushu, ezichaphazela isiphumo sotshintshiselwano lobushushu, okubangela ukuba ukujikelezwa kwangaphakathi kweqondo lokushisa kuyancipha kwaye umphumo olindelekileyo wokutshintshana kobushushu awukwazi ukufezekiswa. Ngenxa yokubambelela kunye nokubekwa kwesikali kunye ne-biological slime, kulula ukubangela ukubola phantsi kwesikali. Kwiimeko ezinzima, kunokubangela amanqaku okuvuza kwi-tube yotshintshiselwano lobushushu kwinqaba yamanzi okupholisa. Emva kophando kwisiza, kwafunyaniswa ukuba ukunyuswa kwenzekile kwisixokelelwano samanzi sokutshiza sangaphandle.
Ipharamitha yokubeka iliso: conductivity
I-conductivity yokuzaliswa kwamanzi okutshiza yi-2290μs / cm, kwaye i-salinity iyonke yi-1705.08mg / L, inkulu kune-1000mg / L eyiliweyo. Xa amanzi okutshiza ehlala engumphunga kwaye amanzi ehlala ezaliswe kwakhona, i-conductivity iyanda ukusuka kwi-2290 μs / cm ukuya kwi-10140 μs / cm emva kweyure ye-1 yokusebenza, i-conductivity yanda phantse amaxesha ama-5, i-salinity iyonke yanda ukusuka kwi-1705.08mg / L ukuya kwi-3880.07mg / L, ukuba i-spray ifike kwi-multiple. inokufikelela kwi-34900 μs / cm emva kweeyure ze-48 zokusebenza, kwaye i-concentration factor ifikelela malunga namaxesha angama-30. Ngoko ke, xa umgangatho wamanzi wokutshiza ungekho kumgangatho kunye nokulungiswa komgangatho wamanzi akwenziwanga, amanzi okutshiza afaka ukulinganisa okunzima kunye neetyuwa ezicwebezelayo kwi-tube yokutshintshwa kobushushu bokutshintshana kwamanzi, ukutshiza umbhobho oyintloko wamanzi, i-spraying yokupholisa isiphumo sokutshiza kunye ne-spraying epholileyo ye-circula, i-spraying epholileyo ye-spray kunye ne-spray epholileyo. i-filler ivaliwe, okukhokelela ekungeneni komthamo wokungena komoya we-fan epholileyo yomoya kunye nokunciphisa umoya wokupholisa umoya.
Ukusombulula ezi ngxaki zingasentla, inkampani ifakele isixhobo sokulinganisa i-inductivity kwi-intanethi kwinqaba yayo yokupholisa ukujonga ukuqhutywa kwamanzi okutshiza ngexesha lokwenyani xa umgangatho wamanzi wokutshiza ungahambelani nomgangatho kunye nokunyangwa komgangatho wamanzi akwenziwanga, i-alarm ivuliwe ukubonelela ngesiseko esichanekileyo sonyango lwamanzi olulandelayo kunye nokutshiza ukuzaliswa kwamanzi.
I-electrode ye-conductivity conductivity eveliswa yi-Shanghai Boqu Instrument Co., Ltd., inoluhlu olukhulu lokulinganisa kunye neempawu ezichasayo, ezisombulula ingxaki ye-sensor fouling ebangelwa yityuwa ephezulu yeesampuli zamanzi kwisayithi, inciphisa umthwalo wokusebenza kwendawo yokusebenza yabasebenzi bokulondoloza, kunye noluhlu lwayo oluphezulu kakhulu lwe-0-2000 kwiimfuno zesayithi ezifunekayo kwi-site.
