NMP distillation zida mu Ningguo nthawi

Dzina la pulojekitiyi ndi 50 tons/tsiku NMP rectification liquid rectification project. NMP zinyalala zamadzimadzi amagwiritsidwa ntchito ngati zopangira. Malingana ndi kusiyana kwa kusakhazikika kwa chinthu chilichonse, ndondomeko yokonzanso mosalekeza ingagwiritsidwe ntchito kulekanitsa madzi, NMP, zigawo zopepuka ndi zigawo zolemera, kotero kuti madzi mu NMP akhoza kuchepetsedwa kuchoka pa 15% muzopangira kukhala pansi pa 100ppm. Njira yochizira zinyalala za NMP imatengera njira yopangira vacuum yokhala ndi nsanja zitatu mosalekeza + njira yodutsa nsanja imodzi + kuyamwa gasi wansanja imodzi. Zida zogwirira ntchito zimakhala ndi nsanja 5, zotengera 18, zosinthira kutentha 10 ndi mapampu 22. Chigawo ichi ndi famu ya thanki, gawo lowongolera komanso gawo lagalimoto yotsitsa ndikutsitsa. Kupanga maola processing pachaka maola 8000, mosalekeza ntchito chipangizo. Kusinthasintha kwa mapangidwe ndi ntchito ndi 60% ~ 120%.
