Isticmaale: Warshad ka shaqaynaysa gaaska dabiiciga ah ee Changqing Oilfield
Sida unugga soo kabashada ethane gaaska ugu weyn ee Shiinaha, warshad gaaska dabiiciga ah ee Changqing Oilfield waa mashruuc muhiim ah oo CNPC ah si kor loogu qaado tayada iyo waxtarka. Si loo gaaro sahayda alaabta ceeriin ee geeddi-socodka soo saarida ethylene ka ethane sida ugu dhakhsaha badan, mashruuca ma aha oo kaliya in ay qaataan caalamiga ah ee horumarsan "qaboojiyaha qaboojiyaha + qaboojiyaha ballaarinta + qaboojiyaha double gaas + distillation heerkulka hooseeyo" ethane soo kabashada ugu weyn ee technology jirka, laakiin sidoo kale korsado technology horumarsan in design injineernimada iyo construction.CNPC si buuxda u faa'iido u faa'iido iyo design SP3 caalamiga ah, saddex nooc oo caalami ah ayaa isticmaala. "iyo warshad wareegta nolosha buuxda" hab, si loo gaaro digital iyo maamulka caqliga leh ee habka oo dhan ee design, soo iibsiga, dhismaha, hawlgalka iyo dayactirka.
Ka dib marka la dhammeeyo warshadda daaweynta gaaska dabiiciga ah, waxa ay xaqiijin kartaa sannadlaha ah processing 20 bilyan cubic mitir oo gaasta dabiiciga ah, wax soo saarka sanadlaha ah ee 1.05 milyan oo tan oo ethane, 450,000 tan iyo hydrocarbon iftiin xasiloon, oo u dhiganta qiimaha wax soo saarka ee beer saliid dhexdhexaad ah, waxa ay sidoo kale calaamadee in Shiinaha ee horumarinta gaaska dabiiciga ah ma aha oo kaliya in ay dhamaystirto horumarinta ku salaysan horumarinta, laakiin horumarinta gaaska dabiiciga ah ee Shiinaha ayaa sidoo kale ma aha oo kaliya in la dhamaystiro horumarka ku salaysan. tayada sare ee horumarinta xidhxidhan-loop ee silsilad warshadaha CNPC ee Shaanxi.
Nidaamka munaaradda qaboojinta ee wareegga biyaha ee xiran ee warshadda gaaska dabiiciga ah waxay isticmaashaa qaboojinta hawada + qaboojinta biyaha si ay u qaboojiso biyaha wareegaya. Sababo la xiriira biyaha qaboojinta ee munaaradda qaboojinta xiran ee biyaha wareega waxay si toos ah u isticmaashaa biyaha dhulka sida biyo dheeri ah, nidaamku wuxuu leeyahay dabeecad cad oo lagu cabbiro ka dib fiirsashada, waana sahlan tahay in la dhigo oo loo hoggaansamo buuxinta munaaradda qaboojinta, aaladda buufinta, iyo tuubooyinka kulaylka, saameynaya saameynta kulaylka isweydaarsiga, taasoo keentay farqiga heerkulka wareegga gudaha hoos u dhaco iyo saameynta isweydaarsiga kulaylka ee la filayo lama gaari karo. Iyadoo ay ugu wacan tahay ku-dhejinta iyo dhigidda miisaanka iyo dhoobada noolaha, way fududahay in la keeno daxalka miisaanka hoostiisa. Xaaladaha daran, waxay keeni kartaa dhibco ka soo daadanaya xidhmada tuubada kulaylka ee munaaradda biyaha qaboojinta. Baaritaanka goobta ka dib, waxaa la ogaaday in qoloftu ay ka dhacday nidaamka biyaha buufinta wareegga dibadda.
Qiyaasta la socodka: dhaqdhaqaaqa
Daawaynta ee buuxinta biyaha buufinta waa 2290μs/cm, iyo wadarta milixdu waa 1705.08mg/L, taas oo ka weyn 1000mg/L nashqadaynta. Marka biyaha buufiyo ay si joogto ah u uumi baxaan oo biyuhu si joogto ah u buuxsamaan, korantadu waxay kor u kacdaa 2290 μs/cm ilaa 10140 μs/cm ka dib 1 saac oo shaqo ah, kororka tamarta ayaa kordhay ku dhawaad 5 jeer, wadarta milixdu waxay ka korodhay 1705.08mg / L ilaa 3880.07mg / L, iyo 2. conductivity gaari karaa 34900 μs / cm ka dib 48 saacadood ee hawlgalka, iyo factor fiirsashada gaadho oo ku saabsan jeer 30. Sidaa darteed, marka tayada biyaha buufinta ma aha ilaa heerka caadiga ah iyo pretreatment tayada biyaha aan la fulin, biyaha buufiyo foomamka scaling daran iyo cusbada crystallized ee wareegyada kulaylka biyaha xidhmo beddelka biyaha, buufin biyaha ugu weyn ee xidhmooyin, buufin biyo qabow, sababa buufinta kulaylka xiran ee tuubada ugu weyn, taas oo sabab u ah buufinta kulaylka xiran ee la xiray. iyo buuxinta waa la xannibay, taasoo keentay in mugga gelitaanka hawo ku filnayn ee marawaxa hawada qaboojiyey iyo hoos u saamaynta qaboojinta hawo.
Si loo xalliyo dhibaatooyinka kor ku xusan, shirkadu waxay ku rakibtay qalabka cabbiraadda inductive online ee munaaradda qaboojinta si ay ula socdaan dhaqdhaqaaqa biyaha buufinta waqtiga dhabta ah marka tayada biyaha buufiyo aysan buuxin heerka caadiga ah iyo prereatment tayada biyaha aan la fulin, alaarmiga waxaa loo hawlgeliyaa si loo bixiyo saldhig sax ah oo biyo ah oo soo socda oo lagu buufiyo buuxinta biyaha.
Electrode conductivity inductive oo ay soo saartay Shanghai Boqu Instrument Co., Ltd., waxa ay leedahay baaxad weyn oo cabbiraadda iyo sifooyinka anti-fouling, kaas oo xalliya dhibaatada dareemayaasha wasakh ah oo ay sababto salinity sare ee muunado biyaha ee goobta, yaraynaysaa culayska shaqada ee hawlgalka goobta ee shaqaalaha dayactirka, iyo baaxadda ultra-weyn ee 0-2000ms / cm ee shuruudaha cabbirka ee goobaha loo baahan yahay.
