## Abstract

ガラス粒子および豊浦砂粒子を充填濾材として, 油水エマルジョンの濾過分離特性と圧力損失について実験的に検討した.清澄淵過理論に基づいて油滴の分離効率を近似的に計算する方法を提案し, 清澄濾過係数を充填粒子径, 粒子の形状係数および濾過速度の関数として実験的に相関した。さらに, 本モデルに基づいて計算される充填層空隙内の油滴の比堆積率変化を, Kozeny-Carman 式に適用して, 充填層の圧力損失および層内部の液圧分布の経時変化を近似計算する方法を提出した.本報は粒子充填層における油水エマルジョンの濾過分離における油滴の分離効率および圧力損失の推定に有益であった.

The separation characteristics and the pressure drop for deep bed filtration of heavy oil/water emulsion were experimentally investigated with granular beds of glass beads and Toyoura sand. A mathematical model for calculating the separation process was proposed on the basis of deep bed filtration theory. The filter coefficient was correlated by empirical formulas with particle diameter, particle shape factor and superficial velocity. Furthermore, a calculation model was presented for estimating the pressure drop and the hydraulic pressure distribution in granular beds by considering the deposition change of oil droplets in the pores calculated by both the deep bed filtration theory and the Kozeny-Carman equation. It was shown that the proposed method was useful for predicting the separation efficiency of oil droplets and the pressure drop for the separation of oil/water emulsion by granular beds.
