Kuyerekeza kusanthula kwa caustic soda ndi phulusa la soda

Osiyana ndi koloko phulusa (sodium carbonate, Na2CO3) ngakhale amatchedwa "alkali", koma kwenikweni ndi wa mankhwala zikuchokera mchere, ndi koloko caustic koloko (sodium hydroxide, NaOH) kwenikweni sungunuka m'madzi amphamvu alkali, ndi amphamvu zikuwononga ndi hygroscopic. katundu.Soda phulusa ndi caustic soda amatchedwanso "ma alkali awiri a mafakitale", onse omwe ali m'makampani amchere ndi mankhwala.Ngakhale kuti ndi osiyana kwambiri wina ndi mzake potengera njira yopangira zinthu komanso mawonekedwe azinthu, kufanana kwawo kwamankhwala kumawapangitsa kukhala olowa m'malo mwa magawo ena akumunsi, ndipo mtengo wawo ukuwonetsanso mgwirizano wabwino.

1. Njira zosiyanasiyana zopangira

Soda wa Caustic ndi wapakati pamakampani a chlor-alkali.Makampani ake opanga pang'onopang'ono asinthidwa ndi electrolysis kuchokera ku njira ya caustic pachiyambi, ndipo pamapeto pake adasanduka njira yamakono ya ionic nembanemba electrolysis.Yakhala njira yodziwika bwino yopangira ma soda ku China, yomwe imawerengera zoposa 99% yazinthu zonse, ndipo njira yopanga ndi yogwirizana.The ndondomeko koloko phulusa anawagawa njira ammonia alkali, ophatikizana alkali njira ndi masoka alkali njira, mmene ammonia alkali njira nkhani 49%, ophatikizana alkali njira nkhani 46% ndi masoka alkali njira nkhani pafupifupi 5%.Ndi kupanga polojekiti ya Trona ya Yuanxing Energy chaka chamawa, gawo la trona lidzawonjezeka.Mtengo ndi phindu la njira zosiyanasiyana zopangira phulusa la soda zimasiyana kwambiri, zomwe mtengo wa trona ndi wotsika kwambiri.

2. Magulu osiyanasiyana azinthu

Pali mitundu iwiri ya soda yomwe imapezeka pamsika: soda yamadzimadzi ndi soda yolimba.Soda wamadzimadzi akhoza kugawidwa mu 30% madzi m'munsi, 32% madzi m'munsi, 42% madzi m'munsi, 45% madzi m'munsi ndi 50% madzi m'munsi malinga ndi gawo lalikulu la sodium hydroxide.Zodziwika bwino ndi 32% ndi 50%.Pakalipano, kutulutsa kwa alkali wamadzimadzi kumaposa 80% ya chiwerengero chonse, ndipo 99% caustic soda ndi pafupifupi 14%.Phulusa la soda lomwe likuyenda pamsika limagawidwa kukhala alkali wopepuka komanso alkali wolemera, onse omwe ali olimba ndipo amasiyanitsidwa ndi kachulukidwe.Kuchuluka kwa alkali wopepuka ndi 500-600kg/m3 ndipo kuchuluka kwa alkali wolemera ndi 900-1000kg/m3.Heavy alkali account for about 50-60%, malinga ndi kusiyana kwa mtengo pakati pa awiriwa ali ndi 10% kusintha malo.

3. Mitundu ndi njira zoyendera

Mitundu yosiyanasiyana yakuthupi imapangitsa kuti koloko ndi phulusa la koloko likhale losiyana mumayendedwe ndi njira.Zoyendera zamadzimadzi zamchere nthawi zambiri zimapangidwa ndi galimoto wamba kaboni zitsulo thanki, ndende yamadzimadzi zamchere ndi wamkulu kuposa 45% kapena zofunikira zapadera ziyenera kupangidwa ndi galimoto ya faifi tambala zosapanga dzimbiri, zamchere zimagwiritsidwa ntchito 25kg thumba la pulasitiki lansanjika zitatu kapena ndowa yachitsulo.The ma CD ndi kusunga koloko phulusa ndi yosavuta, ndipo akhoza mmatumba awiri ndi limodzi wosanjikiza matumba pulasitiki nsalu.Monga mankhwala owopsa amadzimadzi, alkali yamadzimadzi imakhala ndi chigawo champhamvu chopanga ndipo madera ogulitsa amakhala ku North ndi East China, pomwe kupanga kolimba kwa alkali kumakhazikika kumpoto chakumadzulo kwa China.Malo opangira phulusa la soda ndi okhazikika, koma malo ogulitsa ndi omwazikana.Poyerekeza ndi soda, zoyendera zamadzimadzi zamchere ndizoletsedwa, makilomita oposa 300 mgalimoto.
