摘　　要：碳分母液苛化补碱工艺,目的在于解决河南某氧化铝厂混联法氧化铝生产中拜耳法氧化铝产量逐渐增大,烧结法氧化铝产量逐步缩小,系统碳碱量逐渐升高,混联法氧化铝生产两系统产能不能充分发挥的生产瓶颈。As alumina production by Bayer process is increasing, the alumina production by Sintering process is reducing gradually and the amount of sodium carbonate is increasing in the system in an alumina refinery by Mixed combination process, the causticization alkali addition process of carbonated spent liquor is introduced to solve this problem in this paper.
