I-Five-Column Three-Effect Multi-Pressure Disstillation Process
Uhlolojikelele
I-five-tower three-effect ubuchwepheshe obusha bokonga amandla okwethulwa ngesisekelo se-distillation yendabuko ye-five-tower differential pressure, esetshenziselwa ikakhulukazi ukukhiqizwa kotshwala bezinga eliphezulu. Imishini eyinhloko ye-distillation yendabuko eyimibhoshongo emihlanu ehlukene ihlanganisa umbhoshongo ongahluziwe, umbhoshongo wokuhlanza, umbhoshongo wokulungisa, umbhoshongo we-methanol, nombhoshongo wokungcola. Indlela yokushisisa iwukuthi umbhoshongo wokulungisa kanye nombhoshongo wokuhlanza kushiswa isitimu esiyinhloko nge-reboiler, futhi umbhoshongo wokulungisa umhwamuko wewayini unikeza ukushisa kumbhoshongo ongahluziwe wokukhipha isihluzi ngokusebenzisa i-reboiler. Umusi wewayini we-dilution tower unikeza ukushisa embhoshongweni we-methanol nge-reboiler. Umbhoshongo wokungcola usebenzisa isitimu esiqondile ukunikeza ukushisa ngokuqondile, futhi ukusetshenziswa kwesitimu kukhulu. Imishini eyinhloko ye-five-column three-effect differential pressure distillation iphinde ibe umbhoshongo ongahluziwe wokucwilisa amanzi, umbhoshongo wokuhlanza, umbhoshongo wokulungisa, umbhoshongo we-methanol, nombhoshongo wokungcola.
Okwesibili, izici zenqubo
1. Inqubo yokuhlanganisa yokushisa enemiphumela emithathu yokushisisa umbhoshongo wokucwenga amanzi, umbhoshongo we-de-methanol, umbhoshongo wokungcola, bese kuba umbhoshongo wokuhlanjululwa kanye nombhoshongo we-de-methanol ukushisisa umbhoshongo ongahluziwe wokushisisa ukuze unciphise ukusetshenziswa kwesitimu. Ukukhiqizwa kwamathani ophuzo oludakayo olusezingeni eliphezulu ngamathani angu-2.2.
2. Ingxenye yokukhipha umoya kanye nesihlukanisi zihlelwe engxenyeni engenhla yombhoshongo ongahluziwe wokucwiliswa kwe-distillation ukuze kuncishiswe ukungcola okunjengokuqinile okuqukethwe ku-alcohol ongahluziwe kungena ohlelweni lokulungisa, ngaleyo ndlela kuthuthukiswe ukuhlanzeka kotshwala obungahluziwe.
3. I-crude distillation tower reboiler ithatha ubuchwepheshe obunelungelo lobunikazi bokushisisa kwe-thermosyphon esikhundleni semodi yokushisa yokujikeleza okuphoqelekile, futhi umphumela wokonga amandla uyamangalisa, futhi isenzakalo sokuvinjelwa kweshubhu lokushintshanisa ukushisa kwe-reboiler siyasuswa.
4. I-copper piper packing yengezwe ohlelweni lwe-distillation ukuze kuthuthukiswe ikhwalithi yokunambitheka kotshwala obuphelile.
Okwesithathu, indlela yokushisa
Isihluthulelo sokonga amandla wale nqubo imodi yayo yokushisisa, lapho isitimu esiyinhloko sidluliswa ku-reboiler ukushisa ikholomu yokulungisa. Isitimu sewayini se-distillation sinikezwa kukholamu ye-methanol kanye nombhoshongo wokuhlanjululwa nge-reboiler yekholomu ye-methanol kanye ne-reboiler yekholomu ye-dilution. Idilution tower kanye nomhwamuko wewayini we-methanol ngokulandelana ngokulandelana kudluliswa kukholomu yokuhluza kabusha kwekholomu A kanye no-B ukuze kuhlinzekwe umbhoshongo ongahluziwe wokucwiliswa kwe-distillation. I-distillation tower amanzi angcolile akhanyisa isitimu ukuze anikeze umbhoshongo wokungcola. Umbhoshongo owodwa ungena kusitimu nemibhoshongo emihlanu ukuze uzuze ukuhlangana okushisayo okunemiphumela emithathu ukuze kufezwe izinjongo zokonga amandla. Ukukhiqizwa kwamathani ophuzo oludakayo olusezingeni eliphezulu ngamathani angu-2.2.
Okwesine, ukuthambekela kwezinto ezibonakalayo
I-mash evutshiwe evutshiwe idliswa kusukela phezulu kwekholomu yokukhishwa kwe-distillation ngemva kwezigaba ezimbili zokushisa kwangaphambili. Umhwamuko wewayini ongaphezulu kombhoshongo wokucwiliswa kwewayini ongahluziwe uyafinyezwa bese uhlanjululwa futhi uhlanjululwe kumbhoshongo wokuxubha ukuze uhlambulule utshwala obungahluziwe bufinyelele ku-12-18% (v/v). Utshwala obuphansi bushiswa kuqala bese bungena embhoshongweni wokulungisa oseceleni eliphezulu kulayini wekholomu yokuphuza utshwala. Utshwala (96% (v/v)) bukhishelwa kukholamu ye-de-methanol ukuze kuqhutshekwe nokukhipha ukungcola okufana ne-methanol, futhi utshwala obuphelile bukhishwa phansi.
Ezinye izinzuzo
1. Mayelana nokonga amandla, indlela yokushisisa yomjikelezo we-thermosiphon reboiler ingena esikhundleni semodi yokushisa yomjikelezo ophoqelelwe, futhi isebenzisa ubuchwepheshe bethu obunelungelo lobunikazi ukugwema ukuvinjelwa kweshubhu lokushintshanisa ukushisa kwe-reboiler. Ukusetshenziswa kotshwala ngethani lotshwala ngu-20kwh. Uma kuqhathaniswa nokuthuthukiswa kwe-distillation ye-distillation ye-tower emihlanu yokuhluka kwe-distillation engu-40-45kwh, ukonga amandla ngu-50%, okugwema ukugcinwa kwepompo yokujikeleza okuphoqelekile ye-reboiler futhi kwandise impilo yesevisi ye-reboiler.
2. Ukwelashwa kwewayini elingcolile: Utshwala obungcolile obusuka kumbhoshongo wokucwilisa umzimba ongahluziwe, umbhoshongo wokuxubha, umbhoshongo we-methanol, njll., newayini elilula elisuka kusihlukanisi sikawoyela wefuseli lingena embhoshongweni wokungcola, bese uphuzo oludakayo lwasezimbonini lukhishwa ngemva kokuba i-condenser yombhoshongo wokungcola isiphelile. Uwoyela wefuseli uyakhishwa, bese u-alcohol ongahluziwe okhishwe emugqeni oseceleni ongaphezulu ube usudluliselwa kumbhoshongo wokuxubha ukuze kwandiswe isivuno sotshwala sezinga eliphezulu.
3. Mayelana nokuthuthukisa ikhwalithi yotshwala, ngaphezu kwezinyathelo zobuchwepheshe, isakhiwo semishini sithuthukisiwe. Umbhoshongo ongahluziwe we-distillation ufakwe idivaysi yokuhlanza iwayini elingahluziwe, futhi umbhoshongo wokucwiliswa kwe-distillation unikezwa idivayisi yokususa i-copper filler sulfur ukuqinisekisa ukuhlanzeka nokunambitha kotshwala.
Okwesithupha, izinga eliphezulu lokusetshenziswa kwamandla otshwala kanye nethebula lokuqhathanisa ikhwalithi.
