Continuous phase mass transfer in laminar liquid-liquid slug flow

Mass transfer in wetted-wall column with cocurrent laminar liquid-liquid flow

“…These expressions are analogous to those for the local mass-transfer coefficients (Hatanaka, 1984), but Y0 and Y" correspond to the average mass-transfer coefficients for the penetration theory (B -*• 0) and for the Leveque solution (B -°=), respectively. Equation 19 agrees well with the previous two asymptotic solutions (Asai et al, 1985) for all the values of B with a maximum deviation of 2.7%. On the other hand, eq 20 for a < 0 accords with the expression derived from the asymptotic solution for the local mass-transfer coefficients (Byers and King, 1967), within an error of 0.4%.…”

“…Approximate solutions have been proposed by Hatanaka (1984). The corresponding two asymptotic solutions for the average mass-transfer coefficients with a > 0 have been reported by Asai et al (1985), but here the following more compact single empirical expressions are proposed Figure 3. Film-phase mass transfer-dissolution of MIBK in water.…”

“…The density and viscosity of ethylhexyl alcohol were determined by conventional techniques, and the diffusivity of I2 in ethylhexyl alcohol was measured by using a diaphragm cell. All the other properties were taken from the literature (Asai et al, 1983(Asai et al, ,1985Perry and Chilton, 1973).…”

Experimental determination of pressure drop and statistical properties of oil-water intermittent flow through horizontal pipe

“…The presence of slug flow in liquid-liquid vertical flow has been reported by Asai et al [2] and Qiu et al [25]. Oil-in-water slug flow has been studied also in micro-channel flow -see Refs.…”
