Abstract

뭉침과 깨어짐 현상을 동반한 탄산칼슘 침전반응에서 입도분포변화를 실험적으로 연구하고 입자군 수지를 이용해 입도분포 변화를 계산하였다. 이 방법에 따라 계산한 결과는 두 현상이 일어나면서 결정화 과정이 진행되는 실험적 결과를 잘 설명하였다.

Changes of particle size distribution with agglomeration and breakage were experimentally studied in calcium carbonate precipitation. The particle size distribution using population balance equation were calculated. The calculated population density agrees with the experimental data which are agglomeraive and breakable.
