Abstract
An assembly for removing hydrophilic contaminants and a method of removing hydrophilic contaminants such as sodium included in an oil-state liquid using the removing assembly, which is able to remove positively the hydrophilic contaminants such as the sodium included in the oil-state liquid in each process of the plant such as a phenol producing apparatus as well as maintain a certain level of the removing performance for a long duration, consisting of: a coalescing element for coalescing and separating from the oil-state liquid the moisture including the hydrophilic contaminants such as sodium by being penetrated the fiber layer having the characteristics of alkali resistance and solvent resistance, typified by a carbon fiber; a liquid feeding means for feeding and supplying a mixed liquid of the moisture including the hydrophilic contaminants and the oil-state liquid; a water collecting means for collecting the moisture including the hydrophilic contaminants which is coalesced and separated; and a oil collecting means for collecting the oil-state liquid from which the moisture including the hydrophilic contaminants is separated and removed.
