| Abstract: | A study is made on the continuius production of the crystallized Na_2SO3 by alkali absorption of SO_2 gas,neutralization,filtered inpurity under high pressure,crystallization,separation by dehydration,and drying. This production process is short in time for material preparation and high in production,and thus it has a bright future in metallurgical indestry. |
