| Abstract: | 150 kt/a (20 t/h) heavy sodium carbonate through extrusion plant of Zigong Honghe chemical general factory in which bepex company technology of Germany has been imported is the first plant of that kind in China and also is the second same scale bepex technology plant in the world. The paper describes the its process,combination of chemical unit,operation principle of main imported equipment,arrangement character .commissioning and technical revamp situation, Technology and economy of two processes of solid phase hydration and extrusion from light sodium carbonate were compared. It is showed that heavy sodium carbonate through extrusion is the only bulk materials handling process without any chemical reaction and is better than that of solid phase hydration in the aspect of process, power consumption and technical performance. |
