Wogwiritsa: Malo Opangira Mafuta Achilengedwe ku Changqing Oilfield
Monga gawo lalikulu kwambiri la gasi wachilengedwe ku China, malo opangira gasi ku Changqing Oilfield ndi pulojekiti yofunika kwambiri ya CNPC kuti ipititse patsogolo luso komanso luso. Kukwaniritsa kotunga zipangizo kwa ndondomeko kupanga ethylene ku ethane posachedwapa, ntchito osati utenga patsogolo mayiko "refrigerant refrigeration + Kukula firiji + awiri mpweya overcooling + otsika kutentha distillation" ethane kuchira luso lalikulu la thupi, komanso utenga luso patsogolo mu zomangamanga kamangidwe ndi construction.CNPC ntchito zake zonse patsogolo SP3D ndi leverages ubwino padziko lonse SP3D ndi leverages ake comangirirani mbali zonse zapadziko lonse SP3D. kapangidwe nsanja, "ndi moyo wathunthu cycledigital fakitale" akafuna kukwaniritsa digito ndi kasamalidwe wanzeru ndondomeko yonse ya kamangidwe, kugula, kumanga, ntchito ndi kukonza.
Akamaliza kukonza gasi gasi mankhwala, akhoza kuzindikira chaka processing 20 biliyoni kiyubiki mamita gasi, kupanga pachaka matani 1.05 miliyoni a ethane, matani 450,000 ndi khola kuwala hydrocarbon, lofanana ndi linanena bungwe mtengo wa zoweta sing'anga-kakulidwe mafuta munda, komanso zimasonyeza kuti China anamaliza chitukuko cha gasi, koma anamaliza chitukuko cha gasi, koma anazindikira kukula kwa gasi, koma anazindikira kukula kwa gasi chitukuko, komanso anazindikira sikelo zochokera chitukuko cha gasi. chitukuko chapamwamba chotsekeka cha makina amakampani a CNPC ku Shaanxi.
Madzi ozungulira adatseka nsanja yoziziritsa ya malo opangira gasi amagwiritsa ntchito kuziziritsa kwa mpweya + kuziziritsa kwamadzi kuziziritsa madzi ozungulira. Chifukwa cha kuzirala kwa madzi ozungulira madzi otsekedwa kuzirala nsanja amagwiritsa ntchito pansi mwachindunji monga madzi owonjezera, dongosolo ali ndi chizolowezi zoonekeratu kuti lonse pambuyo ndende, ndipo n'zosavuta m'gawo ndi kutsatira kuzirala nsanja filler, chipangizo utsi, ndi machubu kutentha kuwombola, zimakhudza zotsatira kutentha kuwombola, chifukwa mkati kufalitsidwa kutentha kusiyana amachepetsa ndi kuyembekezera zotsatira kuwombola kutentha sangathe kukwaniritsa. Chifukwa chomatira ndi kuyika kwa sikelo ndi matope achilengedwe, ndizosavuta kuyambitsa dzimbiri pansi pa sikelo. Zikavuta kwambiri, zitha kuyambitsa kutayikira mumtolo wosinthitsa kutentha kwa nsanja yamadzi ozizira. Pambuyo pofufuza pamalopo, zidapezeka kuti makulitsidwe achitika mumayendedwe akunja opopera madzi.
Monitoring parameter: conductivity
The conductivity wa kutsitsi replenishment madzi ndi 2290μs/cm, ndi okwana salinity ndi 1705.08mg/L, amene ndi wamkulu kuposa 1000mg/L. Pamene kutsitsi madzi nthawi zonse nthunzi nthunzi ndi madzi zonse kubwezeredwa, madutsidwe ukuwonjezeka kuchokera 2290 μs/cm kwa 10140 μs/cm pambuyo 1 ora ntchito, madutsidwe chawonjezeka pafupifupi 5 nthawi, okwana salinity kuchuluka kwa 1705.08mg/L kwa 3880.07mg/L ngati kutsitsi ndi ndende, ndi kutsitsi ndi 2. amatha kufika 34900 μs / masentimita pambuyo pa maola 48 akugwira ntchito, ndipo ndende imafika nthawi za 30. Choncho, pamene khalidwe la madzi opopera silili loyenera komanso kukonzedweratu kwamadzi sikuchitika, madzi opopera amapanga makulitsidwe aakulu ndi mchere wonyezimira m'matumba ozungulira madzi otentha kutentha, kupopera madzi chitoliro chachikulu, kutsekedwa kwa madzi otsekemera ndi kutsekedwa kwa madzi opopera. chojambuliracho chimatsekedwa, zomwe zimapangitsa kuti mpweya wozizira ukhale wosakwanira komanso kuchepetsa kuzizira kwa mpweya.
Kuti athetse mavuto omwe ali pamwambawa, kampaniyo idayika chida choyezera pa intaneti munsanja yake yozizira kuti iwunikire madulidwe amadzi opopera munthawi yeniyeni pomwe kutsitsi kwamadzi sikumayenderana ndi muyezo komanso kusamalidwa bwino kwamadzi sikunachitike, alamu imatsegulidwa kuti ipereke maziko olondola amankhwala otsatiridwa ndi madzi opopera komanso kubwezeretsanso madzi.
The inductive conductivity elekitirodi opangidwa ndi Shanghai Boqu Instrument Co., Ltd., ali lalikulu muyeso osiyanasiyana ndi makhalidwe odana ndi fouling, amene amathetsa vuto la kachipangizo fouling chifukwa cha mchere wambiri wa zitsanzo madzi pa malo, amachepetsa ntchito pa malo ntchito ya ogwira ntchito yokonza, ndi kopitilira muyeso-akuluakulu osiyanasiyana 0-2000 zofunika pa siteshoni muyeso/cm.
