Njira Yothira Distillation ya Zigawo Zisanu Zitatu-Zotsatira Zambiri
Mwachidule
Zitsanzo zitatu za nsanja zitatu ndi teknoloji yatsopano yopulumutsira mphamvu yomwe inayambitsidwa pamaziko a distillation yachikhalidwe ya nsanja zisanu, yomwe imagwiritsidwa ntchito makamaka popanga mowa wapamwamba kwambiri.Zida zazikulu zopangira distillation zamitundu isanu ya nsanja zimaphatikiza nsanja yopanda distillation, nsanja ya dilution, nsanja yokonzanso, nsanja ya methanol, ndi nsanja yonyansa.Njira yowotchera ndiyoti nsanja yosinthira ndi nsanja yosinthira zimatenthedwa ndi nthunzi yoyambira kudzera mu chowotchera, ndipo nthunzi yamphepo yavinyo imatenthetsa kunsanja yopanda distillation kudzera mu reboiler.Mpweya wa vinyo wa dilution Tower umapereka kutentha kwa nsanja ya methanol kudzera mu reboiler.Nyumba yonyansa imagwiritsa ntchito nthunzi yolunjika kuti ipereke kutentha mwachindunji, ndipo nthunzi imakhala yaikulu.Zida zazikulu zamitundu isanu yamitundu itatu yosiyanitsira distillation ndi nsanja yopanda distillation, nsanja ya dilution, nsanja yokonzanso, nsanja ya methanol, ndi nsanja yonyansa.
Chachiwiri, makhalidwe ndondomeko
1. Njira zitatu zomwe zimagwirizanitsa kutentha kwa kutentha kwa nsanja ya dilution, nsanja ya de-methanol, nsanja yonyansa, ndiyeno kusungunula nsanja ndi de-methanol nsanja kuti zitenthetse nsanja ya distillation kuti kuchepetsa kutentha kwa nthunzi.Kupanga matani abwino kwambiri kumwa mowa ndi matani 2.2.
2. Gawo la degassing ndi olekanitsa amakonzedwa kumtunda kwa nsanja ya distillation yakuda kuti achepetse zonyansa monga zolimba zomwe zili mu mowa wopanda mowa womwe umalowa m'dongosolo lokonzekera, potero kumapangitsa kuti mowa wauchidakwa ukhale wabwino.
3. The crude distillation tower reboiler imagwiritsa ntchito ukadaulo wovomerezeka wa kutentha kwa thermosyphon m'malo mokakamiza kuzungulira kutentha, ndipo mphamvu yopulumutsa mphamvu ndi yodabwitsa, ndipo kutsekeka kwa chubu chosinthira kutentha kwa reboiler kumachotsedwa.
4. Kuyika kwa piper yamkuwa kumawonjezeredwa ku distillation system kuti muwongolere kukoma kwa mowa womalizidwa.
Chachitatu, njira yotenthetsera
Chinsinsi cha kupulumutsa mphamvu kwa njirayi ndi kutentha kwake, komwe nthunzi yoyamba imadutsa mu reboiler kuti itenthetse mzere wokonzanso.The distillation nsanja vinyo nthunzi amaperekedwa kwa methanol ndi nsanja dilution kudzera methanol ndime reboiler ndi dilution column reboiler.Dilution Tower ndi mpweya wa methanol tower umadutsa muzobowoleza za A ndi B kuti zipereke nsanja ya distillation.The distillation tower madzi otayira amayaka nthunzi kuti apereke nsanja yonyansa.Chinsanja chimodzi chimalowa mu nthunzi ndi nsanja zisanu kuti chigwirizane ndi matenthedwe atatu kuti akwaniritse zolinga zopulumutsa mphamvu.Kupanga matani abwino kwambiri kumwa mowa ndi matani 2.2.
Chachinayi, mmene zinthu zilili
Phala wokhwima wofufuma amadyetsedwa kuchokera pamwamba pa ndime ya crude distillation pambuyo pa magawo awiri a preheat.Mpweya wavinyo womwe uli pamwamba pa nsanja ya crude distillation umafupikitsidwa kenaka kuchepetsedwa ndikuyeretsedwa mu nsanja yochepetsera kuti muchepetse mowa wopanda pake mpaka 12-18% (v/v).Chakumwa cham'munsi chimatenthedwa ndikulowa munsanja yokonzanso pamzere wapamwamba wa mzere wa distillation.Mowa (96% (v/v)) amatengedwa kupita ku de-methanol kuti apitirize kuchotsa zonyansa monga methanol, ndipo mowa womalizidwa umachotsedwa pansi.
Ubwino wina
1. Pankhani yopulumutsa mphamvu, njira yotenthetsera ya thermosiphon reboiler imalowa m'malo mwa njira yotenthetsera yokakamiza, ndipo imagwiritsa ntchito ukadaulo wathu wapatent kuti tipewe kutsekeka kwa chubu chosinthira kutentha kwa reboiler.Kumwa mowa pa tani imodzi ya mowa ndi 20kwh.Poyerekeza ndi kusintha kwa asanu oyambirira nsanja kusiyana kuthamanga distillation 40-45kwh, mphamvu yopulumutsa ndi 50%, amene amapewa yokonza reboiler anakakamizika kufalitsidwa mpope ndi kutalikitsa moyo utumiki wa reboiler.
2. Chithandizo cha vinyo wosasadetsedwa: Mowa wodetsedwa kuchokera ku nsanja yopanda distillation, nsanja ya dilution, nsanja ya methanol, ndi zina zotere, ndi vinyo wopepuka kuchokera pamafuta olekanitsa amafuta amalowa munsanja yonyansa, ndipo mowa wakumafakitale umachotsedwa pambuyo poti condenser yonyansa yatha.Mafuta a fuseli amachotsedwa, ndipo mowa wonyansa wotengedwa kuchokera kumtunda wam'mbali umaperekedwa ku dilution Tower kuti muwonjezere zokolola za mowa wapamwamba kwambiri.
3. Ponena za kuwongolera mowa wabwino, kuphatikiza pamiyeso yaukadaulo, kapangidwe ka zida zakonzedwanso.Nsanja ya crude distillation ili ndi chipangizo choyeretsera vinyo, ndipo nsanja ya distillation imaperekedwa ndi chipangizo chochotsera sulfure mkuwa kuti zitsimikizire kuyera ndi kukoma kwa mowa.
Chachisanu ndi chimodzi, mowa wabwino kwambiri wa mowa wamphamvu komanso tebulo lofananiza labwino.
