Icala Lokusetshenziswa Kwesitshalo Sokwelapha Igesi Yemvelo eChangqing Oilfield

Umsebenzisi: Isitshalo Sokucubungula Igesi Yemvelo eChangqing Oilfield

Njengeyunithi enkulu kunazo zonke yokubuyisa i-ethane yegesi yemvelo eShayina, isitshalo sokucubungula igesi yemvelo eChangqing Oilfield siyiphrojekthi eyinhloko ye-CNPC yokuthuthukisa ikhwalithi nokusebenza kahle. Ukuze kufezwe ukuhlinzekwa kwezinto zokusetshenziswa zenqubo yokukhiqiza i-ethylene kusuka ku-ethane ngokushesha okukhulu, iphrojekthi ayisebenzisi nje kuphela ubuchwepheshe bomzimba obuphambili bokubuyisa i-ethane bomhlaba wonke "bokuqandisa ifriji + ukukhulisa ifriji + ukupholisa igesi kabili + ukupholisa okuphansi kwezinga lokushisa", kodwa futhi isebenzisa ubuchwepheshe obuthuthukisiwe ekwakhiweni nasekuthuthukisweni kobunjiniyela. I-CNPC isebenzisa ngokugcwele inzuzo yayo iyonke kanye nokusetshenziswa kwayo, ipulatifomu yokuklama esebenzisana ye-SP3D esezingeni eliphezulu yomhlaba wonke, "nemodi ye-"life cycle full digital factory", ukuze kufezwe ukuphathwa kwedijithali nokuhlakaniphile kwayo yonke inqubo yokuklama, ukuthengwa, ukwakhiwa, ukusebenza kanye nokugcinwa.

Ngemva kokuqedwa kwesitshalo sokwelapha igesi yemvelo，Ingakwazi ukucubungula minyaka yonke ama-cubic metres angama-20 billion egesi yemvelo, ukukhiqizwa kwaminyaka yonke kwamathani ayizigidi eziyi-1.05 e-ethane, amathani angu-450,000 kanye ne-stable light hydrocarbon, okulingana nenani lokukhipha lensimu yamafutha yasekhaya ephakathi nendawo, futhi kuphawula ukuthi ukuthuthukiswa kwegesi yemvelo yaseShayina akuqedi nje kuphela ukuguqulwa kusuka ekuthuthukisweni okusekelwe esikalini kuya ekuthuthukisweni okusekelwe enzuzweni, kodwa futhi kufeze intuthuko evaliwe yekhwalithi ephezulu yeketanga lezimboni le-CNPC eShaanxi.

Uhlelo lombhoshongo wokupholisa ovaliwe ngamanzi olujikelezayo lwesitshalo sokucubungula igesi yemvelo lusebenzisa ukupholisa komoya + ukupholisa amanzi ukupholisa amanzi ajikelezayo. Ngenxa yamanzi apholile ombhoshongo wokupholisa ovaliwe ngamanzi ajikelezayo lusebenzisa amanzi angaphansi komhlaba ngqo njengamanzi engeziwe, uhlelo lunomkhuba osobala wokukhulisa ngemva kokuhlushwa, futhi kulula ukufaka nokunamathela ku-filler yombhoshongo wokupholisa, idivayisi yokufafaza, kanye namashubhu okushintshanisa ukushisa, okuthinta umphumela wokushintshanisa ukushisa, okuholela ekutheni umehluko wokushisa kwangaphakathi unciphe futhi umphumela wokushintshanisa ukushisa olindelekile awukwazi ukufezwa. Ngenxa yokunamathela kanye nokufakwa kwesikali kanye ne-biological slime, kulula ukubangela ukugqwala ngaphansi kwesikali. Ezimweni ezimbi kakhulu, kungabangela amaphuzu okuvuza epaketheni leshubhu lokushintshanisa ukushisa lombhoshongo wamanzi okupholisa. Ngemva kophenyo lwendawo, kwatholakala ukuthi ukukala kwenzeke ohlelweni lwamanzi olusebenzisa i-spray circulation yangaphandle.

Ipharamitha yokuqapha: ukuhanjiswa komoya

Umthamo wokugcwalisa kabusha amanzi okufutha ungama-2290μs/cm2, kanti usawoti ophelele ungama-1705.08mg/L, okungaphezu kuka-1000mg/L oklanyelwe. Uma amanzi okufutha ehlala ehwamuka futhi amanzi egcwaliswa kabusha njalo, ukuhanjiswa kwamandla kuyanda kusuka ku-2290 μs/cm kuya ku-10140 μs/cm ngemva kwehora eli-1 lokusebenza, ukuhanjiswa kwamandla kukhuphuke cishe izikhathi ezi-5, usawoti ophelele ukhuphuke kusuka ku-1705.08mg/L kuya ku-3880.07mg/L, kanti ukuhlushwa okuphindaphindekile kufinyelele izikhathi ezingu-2.3. Uma amanzi okufutha engashintshwa, ukuhanjiswa kwamandla kungafinyelela ku-34900 μs/cm ngemva kwamahora angu-48 okusebenza, futhi isici sokuhlushwa sifinyelela cishe izikhathi ezingu-30. Ngakho-ke, lapho ikhwalithi yamanzi okufutha ingekho ezingeni elijwayelekile futhi ukwelashwa kwangaphambili kwekhwalithi yamanzi kungenziwa, amanzi okufutha akha ukukala okukhulu futhi usawoti ocwebezelwe ku-bundle yeshubhu yokushintshana kokushisa kwamanzi ajikelezayo, ipayipi eliyinhloko lamanzi okufutha, i-closed cooling tower filler kanye nethangi lokufutha, okubangela ukuthi umphumela wokushintshana kokushisa we-circular water spray unciphe, futhi i-filler ivinjiwe, okuholela ekutheni ivolumu yokungena komoya enganele yefeni epholile emoyeni kanye nomphumela wokunciphisa ukupholisa komoya.

Ukuze kuxazululwe izinkinga ezingenhla, inkampani ifake ithuluzi lokulinganisa i-inductive conductivity online embhoshongweni wayo wokupholisa ukuze iqaphe i-conductivity yamanzi e-spray ngesikhathi sangempela lapho ikhwalithi yamanzi e-spray ingahlangabezani nezinga elijwayelekile futhi ikhwalithi yamanzi ingalungiswa kusengaphambili, i-alamu iyavulwa ukuze inikeze isisekelo esinembile sokwelashwa kwamanzi okulandelayo kanye nokuvuselelwa kwamanzi e-spray.

I-electrode yokuqhuba ugesi ekhiqizwa yiShanghai Boqu Instrument Co., Ltd., inobubanzi obukhulu bokulinganisa kanye nezici zokulwa nokungcola, okuxazulula inkinga yokungcola kwenzwa okubangelwa usawoti omningi wamasampula amanzi endaweni, kunciphisa umthwalo womsebenzi wabasebenzi bokulungisa endaweni, kanye nobubanzi bayo obukhulu kakhulu obungu-0-2000ms/cm buhlanganisa izidingo zokulinganisa ezidingekayo endaweni.
