Abstract
PURPOSE: To permeation-separate an oil-free liquid in large quantities by treating an oil-in-water type emulsion of a special compsn. consisting of oil, a surfactant and water with a porous membrane made of specified resin.
CONSTITUTION: An oil-in-water type emulsion contg. oil, a liquid to be separated from the oil and a surfactant is permeation-treated with a porous membrane made of resin with a critical surface tension above 35 dyn/cm or resin mixt. and having through pores with an average pore diameter of 0.03W5μm, a pore diameter distribution -r4/-r3 below 0.5 and an average pore diameter satisfying the relation of equation II between the average particle radius (-rE) of the emulsion and the average pore diameter (-r) of the membrane. The emulsion to be treated has a compsn. represented by equations I [where α=X/(X+Y); X is the vol. fraction of oil in the liquid to be treated; Y is the vol. fraction of a liquid to be separated by treatment other than oil in the liquid to be treated; Z is the amt. (mol/l) of the surfactant; Tb is the b.p. (°C) under 1 atm of the liquid to be separated; T is the temp. of the liquid to be treated; and Tb>T].
