Wogwiritsa Ntchito: Fakitale Yopangira Gasi Wachilengedwe ku Changqing Oilfield

Monga malo akuluakulu obwezeretsa mpweya wachilengedwe ku China, fakitale yokonza mpweya wachilengedwe ku Changqing Oilfield ndi pulojekiti yofunika kwambiri ya CNPC kuti ikonze bwino komanso kuti zinthu ziziyenda bwino. Pofuna kukwaniritsa kupereka zinthu zopangira kupanga ethylene kuchokera ku ethane mwachangu, pulojekitiyi sikuti imangogwiritsa ntchito ukadaulo wapamwamba wapadziko lonse wa "refrigerant friji + expansion friji + double gas overcooling + low temperature distillation" wa ethane recovery main body, komanso imagwiritsa ntchito ukadaulo wapamwamba pakupanga ndi kumanga kwaukadaulo. CNPC imagwiritsa ntchito bwino phindu lake lonse komanso kugwiritsa ntchito kwake, nsanja yapamwamba yapadziko lonse ya SP3D yogwirizana ndi magawo atatu, "ndi full life cycledigital factory mode", kuti ikwaniritse kayendetsedwe ka digito komanso kanzeru ka njira yonse yopangira, kugula, kumanga, kugwira ntchito ndi kukonza.

Pambuyo pomaliza ntchito yokonza mpweya wachilengedwe，Imatha kupanga ma cubic metres 20 biliyoni a gasi wachilengedwe pachaka, kupanga matani 1.05 miliyoni a ethane pachaka, matani 450,000 ndi hydrocarbon yopepuka yokhazikika, yofanana ndi mtengo wotulutsa mafuta apakatikati, ikuwonetsanso kuti chitukuko cha gasi wachilengedwe ku China sichinangomaliza kusintha kuchokera ku chitukuko chokhazikika kupita ku chitukuko chokhazikika, komanso chakwaniritsa chitukuko chapamwamba kwambiri cha unyolo wamafakitale wa CNPC ku Shaanxi.

Dongosolo loziziritsira madzi lozungulira la fakitale yopangira gasi lachilengedwe limagwiritsa ntchito kuziziritsa mpweya + kuziziritsa madzi kuti liziziritse madzi ozungulira. Chifukwa cha madzi ozizira a nsanja yoziziritsira madzi yozungulira, limagwiritsa ntchito madzi apansi panthaka mwachindunji ngati madzi owonjezera, dongosololi limakhala ndi chizolowezi chokulira pambuyo poikamo madzi ambiri, ndipo n'zosavuta kuyika ndi kumamatira ku chodzaza choziziritsira, chipangizo chopopera, ndi machubu osinthira kutentha, zomwe zimakhudza momwe kutentha kumayendera, zomwe zimapangitsa kuti kusiyana kwa kutentha kwamkati kuchepe ndipo mphamvu yosinthira kutentha yomwe ikuyembekezeka siyingakwaniritsidwe. Chifukwa cha kumamatira ndi kuyika kwa sikelo ndi matope achilengedwe, zimakhala zosavuta kuyambitsa dzimbiri pansi pa sikelo. Pazochitika zazikulu, zimatha kuyambitsa malo otayikira mu chubu chosinthira kutentha cha nsanja yoziziritsira madzi. Pambuyo pofufuza pamalopo, zidapezeka kuti kukulira kwachitika mu dongosolo la madzi opopera madzi akunja.

Gawo lowunikira: kuyendetsa bwino mphamvu

Mphamvu yoyendetsera madzi opopera ndi 2290μs/cm, ndipo mchere wonse ndi 1705.08mg/L, womwe ndi waukulu kuposa 1000mg/L womwe unapangidwa. Madzi opopera akamatuluka nthawi zonse ndipo madziwo akuwonjezeredwa nthawi zonse, mphamvu yopititsira patsogolo madzi imawonjezeka kuchoka pa 2290 μs/cm mpaka 10140 μs/cm pambuyo pa ola limodzi logwira ntchito, mphamvu yopititsira madzi imawonjezeka pafupifupi nthawi 5, mphamvu yonse ya mchere inakwera kuchoka pa 1705.08mg/L kufika pa 3880.07mg/L, ndipo mphamvu yochulukirapo inafika nthawi 2.3. Ngati madzi opopera sanasinthidwe, mphamvu yopititsira madzi imatha kufika pa 34900 μs/cm pambuyo pa maola 48 ogwirira ntchito, ndipo mphamvu yochulukira madzi imafika nthawi pafupifupi 30. Chifukwa chake, pamene mphamvu ya madzi opopera siili yokhazikika ndipo chithandizo cha madzi sichikuchitika, madzi opopera amapanga kukula kwakukulu ndipo mchere wosungunuka umayikidwa mu chubu chosinthira kutentha cha madzi ozungulira, chitoliro chachikulu cha madzi opopera, chodzaza choziziritsa chotsekedwa ndi thanki yopopera madzi, zomwe zimapangitsa kuti mphamvu yosinthira kutentha ya madzi ozungulira ichepe, ndipo chodzaza chimatsekedwa, zomwe zimapangitsa kuti mpweya wolowera mpweya ukhale wosakwanira komanso kuchepetsa mphamvu yoziziritsira mpweya.

Pofuna kuthetsa mavuto omwe ali pamwambapa, kampaniyo idayika chida choyezera mphamvu zamagetsi chothandizira pa intaneti mu nsanja yake yozizira kuti chiziyang'anira mphamvu zamagetsi zopopera nthawi yeniyeni pamene mphamvu zamagetsi zopopera sizikukwaniritsa muyezo ndipo kuyeretsa bwino madzi sikukuchitika, alamu imayatsidwa kuti ipereke maziko olondola a kuyeretsa madzi ndi kubwezeretsanso madzi opopera.

Ma electrode oyendetsera magetsi opangidwa ndi Shanghai Boqu Instrument Co., Ltd., ali ndi miyeso yambiri komanso makhalidwe oletsa kuipitsa, zomwe zimathetsa vuto la kuipitsidwa kwa masensa komwe kumachitika chifukwa cha mchere wambiri wa zitsanzo zamadzi pamalopo, zimachepetsa ntchito ya ogwira ntchito yokonza pamalopo, ndipo kuchuluka kwake kwakukulu kwa 0-2000ms/cm kumakwaniritsa zofunikira zoyezera pamalopo.
