Kufunika kwawo kuli mu mtengo wawo wapamwamba pamsika, ntchito yawo monga fakitale yoyeretsera ndi mankhwala, komanso momwe amakhudzira njira zogwirira ntchito zogwiritsira ntchito, kukonza, ndi kutumiza kunja. Chifukwa madzi oundana ndi osinthasintha komanso oyaka, njira zogwirira ntchito zolimba zimagwiritsidwa ntchito poyendetsa, kunyamula, komanso kuteteza chilengedwe. Makhalidwe awo akuthupi, makamaka kuchulukana ndi kulemera kwa mamolekyulu, zimakhudza mwachindunji magwiridwe antchito, kuchuluka kwa kubwezeretsa, komanso kupanga phindu m'machitidwe a mafuta ndi gasi.
Kodi kuchulukana kwa madzi oundana kumayesedwa bwanji panthawi yolekanitsa ma hydrocarbon?
Kuyeza kuchuluka kwa madzi oundana ndikofunikira kwambiri pakuwongolera njira ndi kufotokozera zinthu. Njira zodziwika bwino zoyezera zimaphatikizapo ma hydrometer, omwe amagwiritsa ntchito ma calibrated floats kuti apereke kuwerenga kwachindunji kwa kuchuluka kwa madzi kapena API gravity, ndi ma pycnometer, omwe amazindikira kuchuluka kwa madzi kutengera kulemera kodziwika ndi kuchuluka kwa chitsanzo cha madzi. Njira zapamwamba zowunikira zingagwiritsidwenso ntchito, nthawi zambiri pogwiritsa ntchito zosungunulira kuti ziwunikenso bwino. Ma model oneneratu monga Hankinson-Thomson (HT) ndi njira za Hankinson-Brobst-Thomson (HBT) amayesa kuchuluka kwa madzi a hydrocarbon okhuta ndi opanikizika m'mikhalidwe yogwirira ntchito. M'munda, zida zowunikira monga Lonnmeter inline density meters zimagwiritsidwa ntchito kwambiri poyang'anira kuchuluka kwa madzi mosalekeza komanso molondola, kuthandizira kukonza njira zenizeni. Njira zonsezi zimapangitsa kuti njira zoyezera kuchuluka kwa madzi oundana zigwire ntchito, kuonetsetsa kuti zofunikira zoyendetsera ntchito komanso zamalonda pakulekanitsa madzi a hydrocarbon mu kuyeretsa mafuta zikukwaniritsidwa.
Kodi kuchulukana kwa madzi ofupikitsidwa kumakhudza bwanji zotsatira za njira yoyeretsera mafuta?
Kuchulukana ndi chinthu chachikulu chomwe chimayang'anira momwe ma hydrocarbon amagawikira panthawi yothira mafuta. Kuchulukana kwa madzi oundana kumatsimikiza kugawikana kwa zinthu pakati pa kudula kwa distillate monga naphtha, petulo, ndi dizilo. Kusiyanasiyana kwa kuchulukana kumakhudza magwiridwe antchito, kagwiritsidwe ntchito ka mphamvu, komanso kukolola kwa gawo lililonse la distillation, chifukwa chakudya chopepuka kapena chokhuthala chimafuna mikhalidwe yosiyanasiyana ya reflux ndi magwiridwe antchito. Kuyeza kolondola kwa kuchulukana kumalola kukonza bwino ntchito za reflux drum ndi njira zolekanitsira magawo, zomwe zimapangitsa kuti zinthu zikhale bwino komanso zikhale zofanana. Kafukufuku wasonyeza kuti kusunga kuchulukana komwe kulipo mu chakudya kumaonetsetsa kuti mitsinje yazinthu ikukwaniritsa zomwe zafotokozedwa, kuchepetsa zinyalala ndikukonza bwino chuma cha mafakitale oyeretsera. Kuphatikiza kuchuluka kodalirika kwa ma hydrocarbon condensates kumathandizira kulekanitsa bwino magawo a hydrocarbon ndikuthandizira magwiridwe antchito okhazikika pa distillation ya mafuta osakonzedwa ndi mayunitsi ochotsera condensate.
N’chifukwa chiyani deta yolondola ya kuchuluka kwa mafuta ndi yofunika kwambiri pokonza magawo a hydrocarbon opepuka?
Ma hydrocarbon fractions opepuka, omwe nthawi zambiri amakhala mu C5–C10, ndi ofunikira kwambiri popanga zinthu zamtengo wapatali monga mafuta ndi petrochemicals. Deta yolondola ya kuchulukana ndi yofunika kwambiri pakukonza njira, kuwongolera ubwino, komanso kukwaniritsa zofunikira za malonda. Kuyeretsa ma hydrocarbons opepuka kumafuna kusintha kolondola kwa magawo olekanitsa kutengera mayankho a nthawi yeniyeni a kuchulukana—nthawi zambiri omwe amaperekedwa ndi zida zolumikizirana monga Lonnmeter metres—kuti asunge magwiridwe antchito bwino ndikupewa kupanga kokwera mtengo kosagwirizana ndi spec. Njira zowunikira, kuphatikiza chromatography ya gasi kuphatikiza ndi kusanthula kuchulukana, zimagwiritsidwa ntchito kwambiri poyang'anira kapangidwe kake ndi katundu wakuthupi. Njira yosamala iyi imalola kusinthasintha kwa njira ndi kutsimikizira khalidwe mu kusanthula kwa magawo a hydrocarbon opepuka, zomwe zimapangitsa kuti pakhale njira yabwino yogwiritsira ntchito komanso kuyang'anira mphamvu kudzera mu njira zolekanitsa ma hydrocarbon mu kuyeretsa mafuta.
Ndi njira ziti zabwino zomwe ziyenera kutsatiridwa poyesa zakumwa zoziziritsa kukhosi kuti muyeze kuchulukana kwa madzi?
Kuyesa zakumwa zochepetsedwa kumafuna kutsatira kwambiri njira zabwino kuti zitsimikizire kudalirika ndi kuyimira bwino. Zitsanzo ziyenera kusonkhanitsidwa pogwiritsa ntchito zida zoyera, zopanda kuipitsidwa—zotsukidwa musanagwiritse ntchito—ndi kusungidwa m'zidebe zomwe sizitulutsa kapena kuyamwa ma hydrocarbon. Ma protocol amakakamiza kugwira gawo loyimira la mtsinje wamadzimadzi woyenda, kupewa kutayika kwa zitsanzo chifukwa cha nthunzi kapena kuzima kwa flash, makamaka pazinthu zotentha pang'ono. Zidebe zimatsekedwa ndikulembedwa nthawi yomweyo kuti zichepetse kuwonekera. Ogwira ntchito amatsatira njira zotetezeka zolimba chifukwa cha momwe madzi ochepetsedwa amatha kuyaka komanso kusinthasintha. Miyezo yoyendetsera, monga yomwe imaperekedwa ndi ASTM International, imafotokoza njira zina zokonzekera, kusamalira, ndi kusunga. Kuwongolera kolimba kumeneku ndikofunikira pakuwongolera bwino kwa hydrocarbon condensate ndikuthandizira zotsatira zolondola komanso zogwira ntchito kuchokera ku zida zoyezera kuchulukana kwa condensate.
