Ngo-April, 2019, ikhemikhali ye-Haiyuan yasebenzisa uguquko lobuchwepheshe lokonga amandla lokulungiswa kwephampu yokushisa yokuhlukanisa utshwala ye-propargyl endaweni yonke yokuthunyelwa kwenkampani ngenhloso yokuqinisa ukuphathwa kokukhiqizwa kwamakhemikhali amahle kanye nesiqalo sokuthuthukisa ngokuphelele ikhwalithi yomkhiqizo kanye nokunciphisa ukusetshenziswa.
Ubuchwepheshe bokonga amandla be-propargyl alcohol partition heat pump distillation buthuthukiswe yi-Tianjin University Ngokusekelwe kumishini yokusebenza ekhona kanye nokusebenzisa i-software process simulation calculation.Ubuchwepheshe be-diaphragm distillation kanye nobuchwepheshe bokukhipha isisu sepompo lokushisa kuhlanganiswe okokuqala, futhi lobu buchwepheshe busetshenziselwa inqubo yokuhlushwa ye-propargyl alcohol kanye ne-1,4 butynediol okokuqala.Amandla kagesi asetshenziswa esikhundleni somusi, ukuze ukusetshenziswa kwamandla adingekayo enqubweni yokuhlushwa kotshwala be-propargyl kanye ne-butynediol kungancishiswa cishe ngo-25% uma kuqhathaniswa nenqubo evamile, futhi izindleko zonyaka zingasindiswa ngama-yuan ayizigidi ezingu-20.
Ubuchwepheshe be-diaphragm distillation bokwengeza i-diaphragm eqondile phakathi nekholomu evamile yokuphuza utshwala, futhi uhlukanise ingxenye ephakathi yekholomu evamile yokuhluza ibe izingxenye ezimbili: uhlangothi lokuphakelayo kanye nohlangothi lokubuyisela.Ekusetshenzisweni okusebenzayo, ukuhlukaniswa kwezingxenye ezintathu, izingxenye ezihlanzekile zingatholakala phezulu, maphakathi nangaphansi kombhoshongo ngokulandelanayo, ukuze kubonakale ukuhlukaniswa kwezingxenye ezintathu embhoshongweni owodwa.Umgomo wokonga amandla wobuchwepheshe be-diaphragm distillation uwukuhlanganisa ukuhlukaniswa kwangaphambili kwezingxenye ne-distillation, ukunciphisa ukuxubana kwempahla kanye nobunzima bokuhlukana, ukuze kwehliswe ukutshalwa kwezimali kokuqala kanye nokunciphisa izindleko zokusebenza.Ubuchwepheshe be-diaphragm distillation bufaneleka ngokukhethekile uhlelo oluzohlukaniswa lapho izingxenye zamaphuzu abilayo aphakathi zibala iningi futhi izingxenye ezikhanyayo nezingxenye ezisindayo zithatha ingxenye encane, kuyilapho konga cishe u-30% wemali yokuqala.Izinto zokusetshenziswa zokuhlushwa kotshwala be-propargyl yi-propargyl alcohol 3.2%, amanzi 90.8%, ne-butynediol 6%.Amanzi, njengengxenye ephakathi, alandisa iningi, elihlangabezana nezimo zesevisi yobuchwepheshe be-diaphragm distillation.
Eminyakeni emi-3-5 ezayo, i-Henan Haiyuan Fine Chemical Co., Ltd. izibophezele ekubeni yisilinganiso semboni yamakhemikhali enhle yaseChina, futhi ilwela ukushayela imboni ukuthi ithathe uhlaza, ukonga amandla, ikhwalithi ephezulu kanye umzila wezobuchwepheshe ngokuthuthuka kwawo.
