Nyaya Yekushandisa Chigadzirwa Chekurapa Gasi Rechisikigo muChangqing Oilfield

Mushandisi: Chigadzirwa Chekugadzira Gasi Rechisikigo muChangqing Oilfield

Sechigadzirwa chikuru chekugadzirisa ethane yegesi yechisikigo muChina, chirimwa chekugadzira gasi rechisikigo muChangqing Oilfield ipurojekiti huru yeCNPC yekuvandudza mhando uye kushanda zvakanaka. Kuti vawane zvinhu zvekugadzira ethylene kubva ku ethane nekukurumidza, chirongwa ichi hachingoshandisi chete tekinoroji yepamusoro yepasi rose ye "refrigerant refrigerant + expansion refrigeration + double gas overcooling + low temperature distillation" ethane recovery main body, asiwo chinoshandisa tekinoroji yepamusoro mukugadzira nekuvaka mainjiniya.CNPC inoshandisa zvizere mukana wayo wese uye mashandisirwo ayo, iyo yepamusoro yepasi rose SP3D three-dimensional collaborated design platform, "uye full life cycledigital factory" mode, kuti iwane digital uye nehungwaru manejimendi yemaitiro ese ekugadzira, kutenga, kuvaka, kushanda nekugadzirisa.

Mushure mekupedzwa kwenzvimbo yekuchenesa gasi rechisikigo，Inogona kugadzira gasi rechisikigo rinosvika mabhiriyoni makumi maviri emagetsi pagore, kugadzirwa kwegore negore kwematani mamiriyoni 1.05 eethane, matani zviuru mazana mana nemakumi mashanu emvura uye hydrocarbon ine simba, yakaenzana nehuwandu hwemafuta emumba ane huwandu hwepakati, zvinoratidzawo kuti kukura kwegasi rechisikigo reChina hakuna kungopedzisa shanduko kubva pakukura kwakavakirwa pachiyero kuenda kukukura kwakavakirwa papurofiti, asiwo kwakaita kuti pave nekuvandudzwa kwemhando yepamusoro kwekambani yeCNPC muShaanxi.

Sisitimu yemvura inotenderera inotonhodza yefekitori yekugadzira gasi rechisikigo inoshandisa kutonhodza kwemhepo + kutonhodza kwemvura kutonhodza mvura inotenderera. Nekuda kwemvura inotonhodza yefekitori inotenderera inoshandisa mvura yepasi pevhu zvakananga semvura yekuwedzera, sisitimu iyi ine katsika kekukwira mushure mekuzara, uye zviri nyore kuisa nekunamatira kune chinozadza firita chetower inotonhodza, mudziyo wekupfapfaidza, nemachubhu ekutsinhana kupisa, zvichikanganisa mhedzisiro yekuchinjana kupisa, zvichikonzera mutsauko wekupisa kwemukati unoderera uye mhedzisiro yekuchinjana kupisa inotarisirwa haigone kuwanikwa. Nekuda kwekunamatira uye kuiswa kwechiyero uye slime yebiological, zviri nyore kukonzera ngura pasi pechiyero. Muzviitiko zvakakomba, zvinogona kukonzera nzvimbo dzekubuda kwemvura muchubhu yekutsinhana kupisa yefekitori yefekitori yemvura inotonhodza. Mushure mekuferefeta panzvimbo, zvakaonekwa kuti kukwira kwakaitika musystem yekutsinhana mvura yekuyerera yekunze.

Chikamu chekutarisa: kutenderera kwemhepo

Kufambiswa kwemvura inopfapfaidzwa i2290μs/cm2, uye huwandu hwemunyu i1705.08mg/L, inova yakakura kupfuura 1000mg/L yakagadzirwa. Kana mvura yekupfapfaidza ichiramba ichibuda uye mvura ichizadzwazve nguva dzose, simba rekufambisa mvura rinowedzera kubva pa2290 μs/cm kusvika pa10140 μs/cm mushure meawa imwe chete yekushanda, simba rekufambisa mvura rakawedzera kanenge ka5, huwandu hwemunyu hwakawedzera kubva pa1705.08mg/L kusvika pa3880.07mg/L, uye huwandu hwakawanda hwasvika ka2.3. Kana mvura yekupfapfaidza isina kutsiviwa, simba rekufambisa mvura rinogona kusvika 34900 μs/cm mushure memaawa makumi mana nemasere ekushanda, uye huwandu hwemvura hunosvika ka30. Saka, kana hunhu hwemvura yekupfapfaidza husiri padanho rakajairika uye mushonga wemvura usati waitwa, mvura yekupfapfaidza inoita scaling yakanyanya uye munyu wakakora mu circulating water heat exchange tube bundle, spray water main pipe, closed cooling tower filler uye spray tank, zvichiita kuti heat exchange effect ye circulating water spray iderere, uye filler inovharika, zvichikonzera kusakwana kwe air inlet volume ye air-cooled fan uye kudzikira kwe air-cooling effect.

Kuti vagadzirise matambudziko ari pamusoro apa, kambani iyi yakaisa mudziyo wekuyera mvura inopfuudzwa mudura rayo rekutonhodza kuti iongorore kufambiswa kwemvura inopfuudzwa panguva chaiyo kana mvura inopfuudzwa isingakwane uye mvura isina kugadziriswa zvakanaka, alarm inobatidzwa kuti ipe hwaro hwakarurama hwekugadzirisa mvura uye kudzoreredza mvura inopfuudzwa.

Electrode yekufambisa inoburitsa mvura inogadzirwa neShanghai Boqu Instrument Co., Ltd., ine huwandu hwakakura hwekuyera uye hunhu hwekudzivirira kusvibiswa, izvo zvinogadzirisa dambudziko rekusvibiswa kwemasensa kunokonzerwa nemunyu wakawanda wemasampuli emvura panzvimbo, zvinoderedza mutoro wekushanda kwevashandi vekugadzirisa panzvimbo, uye huwandu hwayo hwakakura hwe0-2000ms/cm hunofukidza zvinodiwa pakuyera panzvimbo.
